What You Need to Know

  • A tripping circuit breaker could be a sign of an overloaded circuit, a short circuit, a ground fault, or a worn-out breaker.
  • Homeowners will want to hire an electrician to determine the cause of the frequently tripping circuit breaker.
  • Electricians may recommend replacing the circuit breaker, installing GFCI outlets, or rewiring part or all of the home.

Q: Every few hours—sometimes minutes!—my living room and one side of my kitchen lose electrical power. I’ll check the breaker panel and, sure enough, a circuit breaker has tripped…again. Should I call an electrician, or is there a simple DIY fix I can try first?

A: While it’s frustrating when a circuit breaker keeps tripping, they are important safety mechanisms. Designed to shut off the electrical current when something goes wrong, circuit breakers are one of the best ways of protecting a home from an electrical fire. “When a circuit breaker trips, typically it is because we use too much electricity, which causes it to overload and turn off,” says Christopher Haas, expert electrician and owner of Haas & Sons Electric in Millersville, Maryland. For those who need an electrical panels 101 refresher course or aren’t sure how to reset circuit breakers, each breaker has an on/off switch and controls a separate electrical circuit in the home. When a breaker trips, its switch automatically flips “off,” and it must be manually turned back on to restore electricity to the circuit. For those wondering, “Is it dangerous if a circuit breaker keeps tripping?” the answer is that it can be, depending on the source of the problem. An electrician can ultimately deal with the root issue, but a little sleuthing will reveal whether it’s something that’s easily remedied.

In many cases, the cause of a circuit breaking tripping is an overloaded circuit.

A circuit overloads when more electrical current is being drawn through the wires than they can handle, tripping the circuit breaker. If this happens, there may be a few additional signs:

  • Buzzing noises coming from outlets
  • Devices charging slowly
  • Electrical outlets not working
  • Flickering lights
  • Scorch marks on outlets and light switches

If a circuit breaker keeps tripping in one room, homeowners can test for circuit overload by turning off all the switches in the affected area and unplugging all appliances and devices. After the breaker is flipped back on, the devices can be turned back on one at a time, with homeowners waiting a few minutes in between to see if the circuit remains on. If the breaker trips before all the appliances are turned on, the experiment can be repeated, this time turning them on in a different order. It may be necessary to do this several times to find out how many appliances can be operated at once before the circuit overloads.

“As a short-term solution, you can unplug unnecessary appliances to prevent tripping circuit breakers. You may still get some trips, but you can limit them by unplugging devices that you don’t need to use,” advises Dan Mock, vice president of operations at Mister Sparky , an electrical company with 90 locations in the U.S. The best long-term solution, however, is to pay an electrician for the cost to rewire the house and add additional circuits. The cost to replace an electrical panel is about $1,274 on average.

Other times, the issue may be caused by a short circuit.

A “short” circuit means that two wires that should not be coming into contact are inadvertently touching, triggering a sudden surge of electricity through the wires. A short can occur in an outlet, a switch, or within an appliance if wires are loose or have been chewed through by mice or pets. Some signs of a short circuit include:

  • Popping sounds
  • Discolored outlets or switches
  • Burning smells

Testing to see if an appliance has a short is similar to testing for an overloaded circuit. When an appliance that has a short in its wiring is turned on, it will immediately trip the circuit. Homeowners can also try plugging it into an outlet in a different room. If the breaker for that room trips, there’s a short in the appliance (if it’s unclear what breaker goes to what room, the breaker can be identified with one of the best circuit breaker finders ). Electrical shorts can be a major fire hazard, so it’s a good idea to call a licensed electrician for this circuit breaker repair. It’s wise to stop using the outlet or appliance until a pro takes care of the problem.

Another potential cause of a circuit breaker tripping is a ground fault.

A ground fault occurs when the electricity running through a home’s wiring diverts from the wiring loop and travels to the ground, usually due to faulty wiring or water infiltration in an outlet or switch box. Water is a conductor, which is why walking through puddles is often listed as something not to do in a power outage in case of downed power lines. Once water makes contact with wires, electricity can jump from the wiring loop and follow the water trail. This creates a surge in electricity leading to a tripped circuit breaker. If a person comes in contact with the electricity that is on its way to the ground, this can result in electrocution. Homeowners may notice a few signs of a ground fault, including:

  • Tripped GFCI (ground fault circuit interrupter) outlets;
  • A burning smell coming from an outlet; and
  • Lights flickering.

Newer electrical breakers have features designed to protect against the danger of ground faults. According to Haas, “Ground fault breakers sense electricity going to earth as opposed to going through the wires of the circuit. You’ll find [these] for bathrooms, kitchens, garages, exteriors, and basements.” GFCI outlets are another safety feature that shut off the electric current within a fraction of a second of sensing a ground fault.

If a ground fault is the problem, the cause of the errant water must be discovered and repaired, and any damaged wiring must also be replaced. It’s also a good idea to install GFCI outlets in rooms where water is commonly used. A GFCI outlet costs $210 on average.

Sometimes a bad or worn-out circuit breaker can be the culprit.

In some cases, the circuit breaker itself may be faulty. Breakers that are old, damaged, or were installed incorrectly may trip frequently for no apparent reason. Alternatively, faulty breakers may not trip when they are supposed to, leaving the home at risk of electrical fire. Some signs of a bad circuit breaker include:

  • The circuit breaker getting hot and tripping frequently;
  • The circuit breaker won’t reset;
  • It has been over 10 years since the breaker was last serviced; and
  • The breaker has scorch marks.

An important electrical safety tip to keep in mind is that resetting a breaker over and over again can cause what is called an arc flash, which is a small electrical explosion that can be deadly. If resetting the breaker once does not remedy the issue, it’s a good idea for the homeowner to hire an electrician near them who knows how to replace a circuit breaker safely. Mock warns, “Don’t take any chances with circuit breakers. Instead, call a licensed electrician who knows the safe ways to replace breaker boxes, upgrade circuits, and diagnose potential electrical problems in your home.” Wiring a breaker box is a job to leave to an experienced electrician.

A professional electrician can help determine the specific cause of a frequently tripping circuit breaker.

Most circuit breaker problems—aside from those explained in the sections above—will need to be inspected and addressed by a licensed electrician. According to the Electrical Safety Foundation International (ESFI) , each year “thousands of people in the United States are critically injured and electrocuted as a result of electrical fires, accidents, [or] electrocution in their own homes.” While homeowners may be tempted to save on electrician costs by attempting circuit breaker replacement or repair themselves, electrical work is not suitable for casual DIYers. “Yes, you have to pay, but you can save many hours of head-scratching by hiring an electrician. Electricians will also have all the right tools for diagnosing and repairing the circuit,” Haas adds. “Lastly, they will come with a warranty/guarantee should something arise, and they will typically return at no additional cost.”

What Causes a Circuit Breaker to Trip?

Trevor

Circuit breakers are an essential component of any home electrical system. They are designed to protect our homes and appliances from electrical overloads and short circuits. But what causes a circuit breaker to trip, and how can we prevent it from happening? In this comprehensive guide, we’ll delve into the common reasons why circuit breakers trip and provide some practical tips to avoid this problem.

A circuit breaker may trip due to three primary reasons: overloads, short circuits, and ground fault surges. Overloads occur when a circuit draws more power than it can handle, usually due to too many appliances operating on the same circuit. Short circuits and ground fault surges happen when a hot wire comes into contact with a neutral wire or a ground wire, causing a large amount of current to flow and overheat the circuit. Less common causes can include faulty wiring, a damaged breaker, or power surges from storms and lightning strikes.

Understanding Circuit Breakers

Before we dive into the reasons, it’s important to understand what a circuit breaker is and how it works. A circuit breaker is an electrical safety device designed to protect an electrical circuit from damage caused by overcurrent, overload, or short circuit. Its primary function is to interrupt the current flow when it detects a fault in the electrical system, thereby protecting equipment and preventing the risk of fire.

Circuit breakers can be reset either manually or automatically to resume normal operation, unlike fuses which must be replaced after operating once. They come in various sizes, from small devices that protect low-current circuits or individual household appliances to large switchgear designed to protect high voltage circuits feeding an entire city.

Common Reasons for a Circuit Breaker to Trip

There are three primary reasons why a circuit breaker might trip:

  • Overloads : This is the most common reason for a circuit breaker to trip. Overloads occur when a circuit is drawing more power than its rated capacity. This can happen when too many appliances or devices are operating on the same circuit at the same time.
  • Short Circuits : A short circuit is a more serious issue. It occurs when a “hot” wire comes into contact with a neutral wire in one of your outlets. This can cause a large amount of current to flow, creating more heat than the circuit can handle, which in turn causes the circuit breaker to trip.
  • Ground Fault Surges : Similar to a short circuit, a ground fault surge happens when a hot wire comes into contact with a ground wire or the metal box that houses the wiring. This causes a sudden rush of electricity that can heat up the circuit, causing the breaker to trip.

Other less common reasons for a circuit breaker to trip include faulty wiring, a damaged breaker, or power surges from storms and lightning strikes.

Preventing Circuit Breakers from Tripping

Here are some practical tips to prevent circuit breakers from tripping frequently:

  • Distribute Electrical Devices : Avoid plugging too many devices into one circuit. Instead, distribute them across multiple circuits to balance the load.
  • Inspect and Replace Old Wiring : Old and faulty wiring can cause short circuits or ground faults. Regular inspection and replacement of old wiring can prevent these issues.
  • Use Surge Protectors : Surge protectors can protect your devices and prevent circuit breakers from tripping during power surges.
  • Replace Old or Damaged Circuit Breakers : If your circuit breaker is old or damaged, it may trip more frequently. Consider replacing it with a new one.

In conclusion, circuit breakers play a vital role in maintaining the safety of our homes. Understanding why they trip and how to prevent it can help us maintain a safe and efficient electrical system. If your circuit breaker continues to trip frequently, it’s best to consult a professional electrician to diagnose and fix the problem. Remember, dealing with electricity can be dangerous, and it’s always better to be safe than sorry.

Frequently Asked Questions

What is the difference between a circuit breaker and a fuse.

Both circuit breakers and fuses serve the same purpose – to protect an electrical circuit from damage caused by an overcurrent, overload, or short circuit. The main difference is how they handle the fault condition. A fuse will melt when overloaded, interrupting the circuit but requiring replacement. On the other hand, a circuit breaker will simply trip (switch off) and can be reset either manually or automatically to resume normal operation.

How can I tell if my circuit breaker is faulty?

Common signs of a faulty circuit breaker include the breaker constantly tripping, the breaker not staying reset, a burning smell or visible burn marks around the breaker, or physical damage to the breaker itself. If you suspect your circuit breaker is faulty, it’s best to consult a professional electrician.

How often should circuit breakers be replaced?

There’s no hard and fast rule for when to replace a circuit breaker. They can last for many years, even decades, if they’re not exposed to excessive moisture or heat and are not constantly being tripped. However, if you’re experiencing frequent tripping or other issues, it’s a good idea to have them inspected by a professional electrician, who can recommend replacement if necessary.

Can I reset a tripped circuit breaker myself?

Yes, you can usually reset a tripped circuit breaker yourself. First, identify the tripped breaker in your electrical panel. It will typically be in the “off” position or in a middle position between “on” and “off.” Simply switch the breaker to the “off” position and then back to the “on” position. However, if the breaker continues to trip, it’s best to consult a professional electrician as it could be a sign of a more serious problem.

Consider this your beginner’s guide to tackling those annoying tripped circuit breakers like a pro. So, let’s dive in and get your power back on in no time!

Understanding Circuit Breakers: The Basics

Before we get into finding a tripped circuit breaker, let’s talk about what they are. A circuit breaker is like a traffic cop for electricity in your home’s electrical panel, also called a service panel or breaker box. It controls the electricity flow, keeping your electrical system safe from overloads and problems. If a circuit breaker trips, it’s like it puts up a “stop” sign for electricity to prevent damage or dangerous situations.

What is a Circuit Breaker?

Think of a circuit breaker as your electrical system’s guardian. It’s like a super cool switch that can be turned on or off manually or even flips itself off automatically when it senses weird stuff happening with the electricity.

If the electricity flow gets too intense for the circuit breaker to handle, it does its magic and disconnects the circuit. This way, it prevents the electrical wires and your fancy appliances from getting all hot and bothered or worse, damaged.

Circuit breakers are like the superheroes of your home’s electrical system, making sure everything stays safe and sound, and avoiding those nasty electrical fires and accidents.

Types of Circuit Breakers and Their Functions

Let’s talk about the different types of circuit breakers. Knowing what they do  can help you pick the right one for your electrical needs Here are some common types of circuit breakers:

  • Magnetic Circuit Breakers: Picture this: a superhero with electromagnetism as their superpower! These circuit breakers use electromagnetic force to trip when the electrical current goes above the limit they’re designed for. They’re like the Flash, super-fast in detecting and reacting to electrical surges.
  • Thermal Circuit Breakers: These circuit breakers have metal strips that act as their sensors. When there’s an overload or a fault, the strips heat up, bend, and cut off the power. It’s like a safety valve that keeps the temperature from getting too hot in your electrical system.
  • Thermal-Magnetic Circuit Breakers: Think of these circuit breakers as the ultimate protectors. They combine the powers of both magnetic and thermal circuit breakers, providing double the defense against overloads and short circuits. They’re like the Avengers of the circuit breaker world, ready to tackle any electrical challenge.
  • Ground Fault Circuit Interrupter (GFCI): GFCIs are the safety experts when it comes to preventing shocks. They’re designed to detect imbalances in electrical current and quickly interrupt the flow of electricity if it’s taking an unintended path, like through water or a person. They’re like invisible shields protecting us from electrical hazards, especially in areas like bathrooms and kitchens.

Common Reasons for Circuit Breaker Trips

Circuit breakers can sometimes get a little jumpy and trip for various reasons. Let’s explore some of the most common causes and how to prevent them:

Overloaded Circuit: When you cram too many appliances or devices into one outlet, it can cause the circuit to get overloaded and trip the breaker. It’s like a traffic jam in your electrical system. The solution? Spread out your power-hungry friends by using different outlets or try to limit the number of appliances on one circuit.

Short Circuit: Ever seen sparks fly when you plug in a faulty appliance? That’s a short circuit. It happens when the “hot” wire (the one that carries electricity) touches the “neutral” wire (the one that returns electricity). It’s like a shortcut that electricity takes, causing a surge and tripping the breaker. Unplug the faulty appliance and call an electrician if it keeps happening.

Ground Fault: If electricity takes a detour through an unintended path, like a person or water, it’s called a ground fault. It’s like a sneaky escape route for electricity. This can trip the breaker to prevent electrical shocks or fires. If you suspect a ground fault, consult with a qualified electrician for help.

Overloaded Circuits: Recognizing the Signs

An overloaded circuit occurs when you have too many electrical devices or appliances drawing power from a single circuit. This can lead to a tripped circuit breaker and potential hazards. Here are some signs that you may have an overloaded circuit:

  • Frequently tripping circuit breaker: If your circuit breaker trips frequently, especially when using certain appliances or devices, it could be a sign of an overloaded circuit.
  • Flickering or dimming lights: When you turn on multiple appliances or devices, you may notice your lights flickering or dimming. This indicates that the circuit is struggling to handle the power load.
  • Warm electrical outlets: If your electrical outlets feel warm to the touch or emit a burning smell, it could be a sign of an overloaded circuit. This can be dangerous and should be addressed promptly.

To avoid overloading your circuits, distribute the electrical load evenly among different circuits in your home. Consider using power strips with built-in circuit breakers to protect against overloads and ensure that you’re not exceeding the capacity of the circuit. If you frequently experience circuit breaker trips due to an overloaded circuit, it may be necessary to consult a licensed electrician to assess and upgrade your electrical system.

Short Circuits: Identifying and Preventing Risks

A short circuit occurs when a hot wire comes into contact with another hot wire or a neutral wire, causing a surge of electricity. This can be caused by wiring issues, damaged appliances, or faulty electrical connections. Here’s how to identify and prevent short circuits:

  • Signs of a short circuit: If you notice sparks, a burning smell, or a sudden loss of power without tripping the circuit breaker, it could be a sign of a short circuit.
  • Inspect the wiring: Check for any visible signs of damage, such as frayed wires, loose connections, or exposed conductors. Damaged or deteriorating wiring can increase the risk of short circuits.
  • Avoid overloading outlets: Do not plug too many devices into a single outlet, as this can increase the risk of a short circuit. Use power strips with built-in surge protectors to distribute the load evenly.
  • Use proper electrical insulation: Ensure that all wires are properly insulated and protected to prevent contact with other wires or surfaces.
  • Seek professional help: If you suspect a short circuit or are unsure about the safety of the wiring in your home, it is recommended to consult a licensed electrician who can identify and resolve the issue safely.

Preventing short circuits is essential for the safety of your home and family. Regularly inspect your electrical system, address any wiring issues promptly, and avoid overloading outlets to minimize the risk of short circuits.

Ground Faults: Safety Measures and Solutions

Ground faults occur when electricity flows through an unintended path, such as water or a person. This can result in electrical shocks and fires. Here are some safety measures and solutions to prevent ground faults:

  • Install Ground Fault Circuit Interrupters (GFCIs): GFCIs are designed to detect ground faults and quickly interrupt the flow of electricity, protecting against electrical shocks. Install GFCI outlets in areas where water is present, such as bathrooms, kitchens, and outdoor outlets.
  • Test GFCIs regularly: GFCIs have a built-in test button to ensure they are working correctly. Test them monthly by pressing the test button and verifying that the power is cut off. Reset them afterward to restore power.
  • Avoid using electrical devices near water: Keep electrical devices away from water sources to reduce the risk of ground faults. This includes using extension cords and appliances in wet areas.
  • Inspect and maintain electrical wiring: Regularly inspect the wiring in your home for signs of wear, damage, or aging. Replace any damaged or worn-out wiring to minimize the risk of ground faults.
  • Consult a licensed electrician: If you experience frequent ground faults or are unsure about the safety of your electrical system, it is recommended to consult a licensed electrician for professional inspection and repairs.

Picture this: you’re watching TV or browsing on your phone when, suddenly, half the lights in your home turn off. You check your circuit breaker and flip one of the switches back to “ON,” but an hour later it trips again…and again. Sound familiar? Having your circuit breaker trip over and over can be frustrating, but don’t sweat. In this article, we’ll explain the most common causes of a tripped circuit breaker. Keep reading to learn which causes might apply to your situation, when to try do-it-yourself fixes, and when it’s best to call an electrician.

Things You Should Know

  • The most common causes of tripped circuit breakers are overloaded circuits, short circuits, and ground faults.
  • Test for overloaded circuits by resetting your breaker and plugging in devices until it trips again. The device that caused the trip is overloading the circuit.
  • Test for short circuits by resetting your breaker and plugging in items into different sockets. The device or socket that always trips the breaker likely has a short circuit.
  • Have an electrician test for ground faults if you’ve already ruled out overloaded and short circuits. Ground faults are too dangerous to test for on your own.

Step 1 Overloaded circuits

  • For example, if your bathroom and kitchen are part of the same circuit—that is, the plugs in your kitchen and bathroom are all connected to the same switch on your circuit breaker—then the breaker might trip if you run your microwave and hair dryer at the same time.

Step 2 Short circuits

  • Short circuits often happen when wires come loose or get damaged by corrosion or wear and tear, or even from an animal chewing through them. [3] X Research source
  • Short circuits can occur in the wiring in your home or in individual devices. For instance, a refrigerator can have a short circuit due to a loose wire.

Step 3 Ground faults

  • Ground faults often happen due to water leaking into outlets or devices. They also occur when loose or corroded wires come into contact with ground wires, or when defective devices cause electricity to flow to a ground wire.

Step 1 Unplug all devices affected by the tripped switch.

  • If you have multiple devices sharing a single outlet in the area affected by the tripped breaker, it’s likely that that group of devices is causing the overload. [6] X Research source

Step 2 Turn on the circuit breaker switch that was tripped.

  • Wear safety goggles or stand to the side of a breaker when flipping a switch to “ON” in case of sparks.
  • If the switches aren’t labeled, narrow down the affected area by flipping the switch to “ON” and checking which devices and lights turn on again.
  • If multiple switches tripped at the same time, there might be an overloaded circuit in more than one area of your home, or you may have another issue such as a short circuit or ground fault.

Step 3 Reconnect devices one by one to find what’s overloading the circuit.

  • If none of the devices immediately trip the circuit breaker, it’s possible that your circuit isn’t getting overloaded right away. Leave the devices plugged in and turned on for a few minutes to see if the breaker trips again.
  • If the breaker trips after several minutes, try the process again, but leave 1-2 less important devices unplugged. Eventually, you’ll find a combination of devices that doesn’t trip the circuit breaker.

Step 4 Plug the device that was tripping the breaker into a different outlet.

  • Leave your devices plugged in and on for a few hours. If the circuits are not overloaded, the circuit breaker shouldn’t trip.
  • If the circuit breaker trips for the same part of your home again, plug additional devices into other outlets. You may need to try different combinations of plugs and outlets to see which combination doesn’t overload your circuits.
  • If you try several combinations and the breaker continues to trip, it’s possible that you have a short circuit or ground fault somewhere in your home.

Step 1 Unplug affected devices and turn the tripped switch back on.

  • If devices are plugged into surge protectors, unplug each device from the surge protector before unplugging the surge protector itself.

Step 2 Plug devices back in one by one to find the short-circuit.

  • If the circuit breaker trips whenever you plug something into a particular outlet, you probably have a short circuit in that outlet.
  • If one particular device always trips the breaker, but other devices don’t, you probably have a short circuit in that particular device.

Step 3 Test potentially shorted devices in other outlets.

  • If the device you want to test is too large to move—such as a kitchen refrigerator or washing machine—use a long extension cord to reach other outlets.

Step 4 Have a licensed electrician repair any short circuits.

  • If you find a short circuit in an individual device, check if your product is covered by a warranty. If it is covered, you might be able to get it fixed or replaced for free.

Have a licensed electrician check your home for ground faults.

  • Tell your electrician which outlet or area of your home is affected by the tripped circuit breaker. This will help them narrow down the exact problem.
  • Avoid using sockets that appear water-logged or that show signs of water damage.

Understanding Circuit Breaker Tripping

Understanding Circuit Breaker Tripping

Circuit breakers are protection devices for electrical circuits. When too much current passes, the breaker trips, stopping the flow of electricity and preventing damage. This can be caused by faulty wiring, too many appliances on one circuit, or a ground fault.

Overloading can cause tripping. This happens when too many devices are connected to a single circuit. Heat builds up in the wires, which can start fires or cause damage. To prevent this, distribute loads across multiple circuits and don’t connect too many appliances to one outlet.

Short circuits also lead to tripping. This happens when two wires with opposite charges come in contact or when a wire touches something grounded. This causes an immediate surge in current that triggers the breaker. Check for exposed wires or insulation damage, and call an electrician if you spot any signs of trouble.

Ground faults can also cause tripping. This happens when there’s an unintentional connection between a live wire and a conductive surface. Install GFCIs to avoid this.

In short, know what causes circuit breakers to trip. Identify potential hazards like overloading, short circuits, and ground faults. Take steps to prevent accidents and ensure your electrical equipment is safe. If you’re unsure how to handle electrical problems, call a licensed electrician.

Overloading Causes

Circuit breakers trip to stop overheating, electrical fires, and damage to electrical parts. Plugging in too many devices can cause the circuit to become overloaded, so the breaker trips to cut off the power.

Short circuits are like a blind date gone wrong. They can be explosive, and often end in disaster. This happens when a hot wire comes into contact with a neutral or insulation/water. This throws off the electric balance, causing danger and tripping.

Short Circuit Causes

A short circuit happens when a low-resistance path appears between two points in the circuit that aren’t usually connected. This can cause too much current to flow, making a circuit breaker trip. Insulation or wiring damage, faulty appliances, and circuit overload are the most common reasons for a short circuit. It’s critical to identify and fix the root cause quickly to avoid electrical fires and other dangers .

When too much power passes through a circuit, the circuit breaker will automatically turn off. It’s designed to protect wiring and guard against electrical accidents . But if the breaker trips regularly, there may be underlying issues that need investigation and repair. Often times, this means upgrading or replacing components.

Sometimes short circuits are caused by human error or wear and tear. But they may also come from design or installation problems. Planning and upkeep from local electricians can keep electrical systems running safely and appropriately for a long time. If your circuit breaker is tripping a lot, get an experienced technician to review your system and suggest solutions that match your needs and budget .

Overheating Causes

Circuit breakers are essential safety features. They stop electrical fires and protect your appliances. When overloaded, too much current flows, producing heat. This causes the breaker to trip!

Other factors can cause overheating. Damaged insulation on wires increases resistance. Loose connections add resistance and heat. High temperatures and poor ventilation worsen the situation.

It’s important to maintain and service the electrical system. Checks of all components will make sure they work efficiently. To avoid tripping, prevent overheating. This will reduce energy consumption and safeguard equipment. So, let’s learn about circuit breakers and how they deal with overloads!

It is crucial to select the right type of breaker. Each one has its own advantages in specific situations. For instance, thermal circuit breakers are perfect for small appliances like hair dryers or irons . Meanwhile, magnetic circuit breakers are great for bigger loads such as air conditioners or refrigerators .

Remember, circuit breakers are like Beyoncé – they can handle a lot, but have their limits.

Circuit Breaker Ratings and Specifications

Circuit breakers are designed to protect electrical circuits from overloads. To ensure that circuits and appliances are safe, the ratings and specifications of circuit breakers need to be understood.

If a circuit breaker trips often, it may mean there’s an issue. It’s best to get professional help in these cases. Time to go on a hunt for your electrical wiring!

Troubleshooting Circuit Breaker Tripping

Circuit breakers can flip out for multiple reasons, like overloads , short circuits , and ground faults .

Overloads happen when too much electricity passes through the circuit, creating too much heat and tripping the breaker. Short circuits are when two or more wires touch, resulting in extra current. Ground faults occur when the power takes an unexpected route, like through a person’s body.

To figure out why your circuit breaker is tripping, it’s important to figure out what is going on and act accordingly. Inspections and maintenance can also help avoid future tripping.

Stop your circuit breaker from misbehaving with these prevention tips!

Preventing Circuit Breaker Tripping

A circuit breaker tripping can be prevented with understanding. When circuits are overloaded, breakers trip to avoid overheating and potential fires. Here are 3 steps that can help you prevent circuit breakers tripping:

  • Know the electrical load – work out how many appliances & devices are connected to one circuit. Don’t overload them by spreading high-energy equipment across multiple circuits .
  • Look after your appliances – ensure all your appliances & devices are in good condition, with no damaged cords or frayed wires.
  • Upgrade your system – if you’re tripping breakers often you may need to upgrade the electrical system with higher capacity breakers or more circuits.

Plus, investing in surge protectors can also assist in preventing circuit overload and subsequent tripping of breakers. By following these steps you can make sure your home’s electricity runs safely and without interruption due to circuit breakers tripping.

Remember: these precautions will keep you from tripping more than just your circuit breakers!

Safety Precautions

Safety must be taken seriously when dealing with circuit breakers . Always switch off the main power supply before beginning work. Wear protective gear such as insulated gloves and boots to stay safe from electrocution. Never touch wires or components inside the box without proper training. Keep the area around the breaker box free from any flammable substances. Inspect breakers for damage or wear regularly .

Label each circuit breaker correctly . Test them frequently for functionality. This will help identify circuits quickly in case of an emergency. These precautions and practices ensure safety while dealing with circuit breakers. When in doubt, blame it on the circuit breaker – it’s always a good scapegoat for electrical woes!

Circuit breakers are essential components of any electrical system. They stop too much current flowing and thus, protect against potential fires . The most common cause for tripping is overload. But, other causes like short circuits and ground faults can also cause the breaker to trip. When it trips, there is something wrong that needs to be fixed right away.

Short circuits occur when two wires touch each other. This creates a low resistance path which allows a lot of current to flow with no load. Ground faults occur when the hot wire touches something incorrectly wired or with a damaged cord.

To prevent tripping, regular maintenance of the electrical system is needed. Keeping appliances in good condition, replacing worn-out cords and fixtures, and periodically checking for loose wires all help reduce the chances of tripping. In summary, understanding why the breaker trips and taking precautionary measures will keep you safe and save you repair costs.

First, the two talk about the different sizes of breakers before moving on to the different types. Finally, Heath shows Kevin how to test certain breakers to ensure they’re working properly.

Circuit breakers exist to protect people, appliances, and homes from dangerous electrical current. However, few people understand why the trip and how they operate. Master electrician Heath Eastman shows host Kevin O’Connor why this happens, and even explains a few different types of breakers.

All About Electrical Systems

Breakers Protect Circuits

When electricity comes into the house, it flows through the electrical service panel. From there, the electricity flows out through different branches in the house, each controlled by a circuit breaker. Should a branch begin to overload and overheat, the breaker will trip to prevent damage.

Breaker Sizes

There are two main sizes of breakers in a house: 15 amp and 20 amp. The amp rating explains how much current the breaker can handle before it will trip, and each requires a certain size of wire. Fifteen-amp breakers require a 14-gauge wire, while 20-amp breakers require a 12-gauge wire.

How They Work

A 15-amp breaker won’t necessarily trip the moment it experiences a spike above 15 amps. Many devices draw more amps upon start-up, and these breakers allow those temporary spikes. However, should the breaker sense elevated amperage for longer than is typical, it will trip to prevent the circuit from overheating.

GFCIs and AFCIs

Beyond circuit overload protection, there are other types of breakers that offer additional coverage. These include GFCI breakers and relatively-new AFCI breakers .

GFCI (ground fault circuit interrupter) breakers need to experience the same amount of current going out as coming back through the circuit. If the breaker experiences a drop in returning current, it assumes that the circuit is leaking, whether it be through a water source or a person. When this imbalance occurs, the GFCI trips immediately.

AFCI (arc fault circuit interrupter) breakers sense when the circuit, a device, or an appliance is arcing (the current is jumping from the circuit and onto something else or someone). When the breaker recognizes the arc signature, it trips immediately. These breakers are relatively new and look similar to GFCI breakers, but they’re becoming a code requirement in most locations.

How to Test Breakers

Homeowners, electricians, and inspectors can test their breakers. There are devices that users can plug into an outlet and replicate an error. These devices, known as AFCI/GFCI testers, can trip the breaker altogether or replicate a ground or arc fault, triggering the breaker. This is one of the best ways to ensure that a breaker is working properly.

When to Call a Professional

If a circuit is continuously tripping, or you know that it should be tripping and isn’t, be sure to call in a professional. An electrician will be able to determine the cause of the issue and make sure your circuit breakers and electrical system are safe.

Heath explains what a circuit breaker is, why they trip and how it protects a home. A circuit breaker is a device, installed in the electrical panel, that controls whether power can be sent from the panel through a circuit. Heath explains this ability is controlled by a switch that can be operated either manually—like when a person wants to interrupt power for service—or automatically, like a breaker trip.

He says power overloads, current “leaks”, and arcs are the three reasons that would cause a breaker to trip. A Power overload happens when a device is calling for more power than a receptacle , or a circuit is designed to provide. Current “leaks” are caused when current strays from the circuit for whatever reason, though it happens most commonly when moisture is present. Arcs can happen when the wire breaks down over time (due to overloads but also due to other factors, like animals chewing the wire and other decay) but what Heath sees the most is human error.

If a specific receptacle is consistently tripping the breaker, Heath advises to have a licensed electrician identify the problem to ensure the work is done safely.

Breaker Test

A circuit breaker tripping results from short circuits, overloaded circuits, and ground faults. In each case, an unintended excessive flow of current triggers the trip. You must reset the circuit breaker by flipping it back on to restore power.

Circuit breakers trip because they cannot handle the amount of current running through them. Tripping the circuit breaker interrupts the flow of electricity and protects your devices or appliances from damage.

Without electrical circuit breakers , the possibility of electrical fires would be much higher.  

This guide looks at what causes circuit breakers to trip, what you can do, and how to identify a bad breaker.

What Would Cause a Circuit Breaker to Trip

There are three leading causes of circuit breaker trips:

  • circuit overload
  • electrical faults (i.e., ground faults and arc faults)
  • short circuits

Below are factors that can cause circuit breaker trips. 

Circuit Overload

A circuit overload happens when the flow of electric current running through the circuit exceeds the amperage of the devices it serves. 

For example, if your microwave is a 12.5 amp appliance, you can run it on a 15 amp circuit. That means your microwave is safe as long as the amperage running through the circuit is 15 amps .

However, if the circuit receives an excessive electrical load over 15 amps , it will automatically trip to protect your device from damage. If the circuit doesn’t trip, the excess current will fry the circuit in your microwave. 

Also, if you operate too many appliances and devices on one circuit, its internal mechanism heats up, causing the breaker to trip. 

Circuit overload is the most common reason for breakers tripping. 

Ground Faults

A ground fault occurs when the active wire comes into contact with a ground wire made of bare copper. Sometimes, this fault may happen when the hot wire touches the metal box connected to the ground wire.

Excessive current flows once the active wire touches the ground wire, flowing into the earth. If you step on the affected area, ground faults can cause shock and even electrocution. The uncontrolled flow of electricity will cause the circuit breaker to trip.

Arc Faults 

An arc fault happens when exposed faulty wiring touches, causing the electric current to arc at the meeting point. As a result, sparks occur, which can ignite an electric fire.

A corroded or loose connection is the main culprit for arc faults. Circuit overloads, ground faults, or short circuits trip an AFCI (Arc Fault Circuit Interrupter) circuit breaker.

Arc faults result from damaged, loose, or corroded terminals and wires. The arc fault builds up over time as the heat due to the cable damage and terminals build up to the point of ignition.

Short Circuits

A short circuit occurs when an active wire touches a neutral wire, and the electrical current takes an unintended path of least resistance. 

The common cause of short circuits is frayed wires coming into contact when the wires touch. The electrical current flow increases significantly, causing the circuit breaker to trip to stop the electricity from damaging appliances.

It is a short circuit because the current bypasses the proper circuit wiring channels and flows through a shorter, unplanned pathway.

Short circuits occur 

  • When insulation melts and wires are exposed
  • Within appliances with damaged internal wiring
  • Due to damaged and frayed extension or appliance cords

How do You Fix a Breaker that Keeps Tripping?

A dedicated circuit breaker tripping indicates too much current flowing through the wiring or connection to the outlet.

Here is a step-by-step guide to follow when you notice the first trip:

  • Begin by turning off all the appliances and unplug electrical devices from the outlet. Also, switch off light fixtures and unplug those that you can. This prevents any appliances from damaged when the breaker is reset and a sudden surge of power comes through.
  • Open the circuit panel or box and locate the on and off buttons of the circuit breaker. You may notice an orange or red color on the breaker when it is off. 
  • Flip the switch from off to on to reset the circuit breaker. Once the breaker is reset, you can switch and test the appliances to see if the electrical power is flowing.
  • Keep safe as you reset the breaker by working from the side of the electrical box instead of the front. That way, you will avoid any sparks (should there be any) when you switch the breaker back on.
  • Some people prefer to switch the main electrical switch when working on the circuit breaker for added safety. 

Types of Circuit Breakers

Standard circuit breaker.

Standard circuit breakers monitor the modulation of the electric current coming into your devices and appliances. 

This circuit breaker stops the current from flowing when it detects the excessive flow of electricity. 

Standard circuit breakers come in two forms:

  • Single-pole circuit breakers
  • Double pole circuit breakers

Single-Pole Circuit Breakers

Single-pole circuit breakers are the most common breakers in homes and buildings. They monitor the electric current’s flow in one wire and trip if that wire experiences a very high influx of electricity.

These breakers deliver only 120 volts and work well for 15 to 30 amp circuits. Single-pole circuit breakers come with one switch in the back. 

Double-Pole Circuit Breakers

The double-pole circuit breakers monitor the current in two wires simultaneously. You will notice two switches on the back of these breakers.

The double-pole circuit breakers will trip even if only one of the wires receives too much current. They can accommodate between 15 to 200 amps while delivering 240 volts. 

Single-pole breakers are a good fit for lighting fixtures and other standard home outlets. On the other hand, double-pole breakers work for larger appliances like dryers and washing machines. 

Ground Fault Circuit Interrupter (GFCI)

The GFCI circuit breaker interrupts the line due to ground faults. They trip when the current starts to follow an uncharted path into the ground. These ground fault surges occur when a foreign conductor, like water, comes in contact with a receptacle .

At the same time, they offer protection against circuit overloads and short circuits. 

GFCI circuit breakers come built into specialized outlets required for wet areas in the home, including :

  • Outdoor areas like the balcony, patio, porches, and decks
  • Laundry rooms
  • Swimming pools
  • Six feet from a sink
  • Six feet from the bathroom

These breakers help prevent shock or electrocution should the electrical outlet contact water. 

Arc Fault Circuit Interrupter (AFCI) 

The AFCI circuit breaker detects normal and abnormal arc faults, so it will trip when it detects a dangerous arc fault that can cause a fire. 

The AFCI circuit breaker doesn’t work to protect devices and appliances plugged into an outlet. It works to prevent electrical fires due to faulty connections and wiring. The internal sensing mechanism in the circuit breaker senses the conditions of an electric arc, and the circuit trips to avoid an electric fire.

AFCI protection can also be built into an outlet. The National Electrical Code (NEC) requires these types of breakers to feature in :

  • Common rooms
  • Laundry areas

AFCI and GFCI circuit breakers can co-exist and complement each other for the best protection.

Combination All Fault Circuit Interrupter (CAFCI)

The CAFCI breaker senses and reacts to any electrical fault, including ground and arc faults.

CAFCI is a relatively new technology that meets new NEC requirements for circuits requiring arc and ground fault protection.

Do Circuit Breakers Get Weak?

A circuit breaker can wear out and become weak. If a breaker trips frequently, the thermal or magnetic element can lose calibration, causing it to trip at lower amp loads than intended. A breaker constantly under thermal stress caused by overloading the circuit will eventually trip more frequently.

Let’s not forget breakers are not impervious to damage. As the internal mechanical parts wear out, they become very sensitive and may not hold under normal load amperage and temperatures.

Electricians refer to this as a bad breaker .

Will a Bad Breaker Keep Tripping

By definition, bad breaker malfunctions, so it will keep tripping until it is either replaced or rectified .

A licensed electrician performs this simple test to see if a breaker will keep tripping and determine if it can be repaired or replaced in the following steps.

  • The electrician will switch off all the fixtures and appliances in the house. Also, unplug everything.
  • Find the malfunctioning circuit breaker . The electrician will go to the electrical box and locate the breaker lighting orange or red or the one with the switch off.
  • They will ascertain that it is the correct circuit breaker. After that, the electrician puts the breaker off.
  • With the switch on, the breaker is back on as well. The electrician will plug the appliances into the outlet with the problem circuit breaker. Now, they will turn the devices and appliances on. 

If the breaker trips, the electrician will investigate the circuit’s current amount. The breaker is bad if the current is according to the appliance’s rating.

How You know if a Circuit Breaker is Bad

Breakers do wear out after a while. It has a problem if the breaker doesn’t stay on after resetting it.

Since the circuit breaker controls the electric flow in the house, it is essential to monitor it and catch signs that it has gone bad early.

Here are key signs that denote a bad circuit breaker :

It Frequently Trips

Frequent tripping could be because of a bad breaker. After tripping and resetting, your circuit breaker should stay on unless it detects high current flow. 

To ensure that the issue is not the electricity but the circuit breaker, call an electrician to examine your electricity’s flow and determine whether it is the cause of the constant tripping.

If it is not, then the circuit breaker is the problem. 

The Breaker Overheats

Electrical systems will heat up when active. Typically a breaker can heat to about 60°C (140°F) before problems arise.

Terminations for standard rated breakers: UL 489 Paragraph 7.1.4.2.2 says the temperature rise on a wiring terminal at a point to which the insulation of a wire is brought up as in actual service shall not exceed 50°C (122°F). Terminations for 100% rated breakers: UL489 Paragraph 7.1.4.3.3 says the temperature rise on the termination shall not exceed 60°C (140°F). Handles, knobs, and other user surfaces: UL489 Paragraph 7.1.4.1.6 says the maximum temperature on handles, knobs, and other surfaces subject to user contact during normal operation shall not exceed 60°C (140°F) on metallic and 85°C (185°F) on nonmetallic surfaces.

Call an electrician immediately if the breaker becomes too hot.

There are Scorch Marks

Scorch marks around receptacles, appliances, and the electrical box should tell you your circuit breaker has gone bad.

The burn marks indicate that wiring insulation has melted off and the circuit wires are now sparking and emanating heat or fire. That means that the circuit breaker did not interrupt the excess current and reached the wires and burned them. 

You may see melted wire sheathing on the wire where it connects to the breaker.

Professional electricians can use a  thermal imaging infrared camera to locate the heat source. The infrared camera allows them to pinpoint the problem area through the walls and other construction material.

A Burning Smell

Sometimes you may smell the insulation burning, but no scorch marks are present to denote which outlet is the problem. 

With the help of the infrared camera, an electrician can help locate electrical issues. 

If you encounter a burning odor, shut off the main power and call for emergency service from an electrician. 

The electrical wires burn because power surges through the circuit, melting the wire insulation.

What is Nuisance Tripping

Nuisance tripping is when a breaker trips without a fault to warrant the interruption to the electric current flow.

Nuisance tripping occurs due to several reasons:

Stringent Protection on Circuits 

Sometimes the circuit is protected by stringent conditions that detect any variance as a fault and cause a trip. 

Such stringent conditions can be tuned to accommodate the home’s or building’s electric needs.

A Highly Sensitive Circuit Breaker

In some cases, the circuit breaker has been set to susceptible settings so that they can detect even the slightest fault, even a minor average variance.

For example, the manufacturer can set an AFCI circuit breaker to sensitive standards to detect another circuit’s arc. This common issue may occur in a daisy chain where the circuit breakers connect in a linear series. There may be a faulty electrical outlet you are unaware of on the circuit. It is common for multiple rooms to share a breaker in older houses.

The Breaker Encounters Power Under Different Conditions

The variation in the current is normal, but the breaker responds to it by tripping because the flow is outside the breaker’s regular operation.

Your circuit breaker is tripping because the voltage it is encountering is not within the standard operation. You will need to adjust the circuit breaker or the voltage to eliminate nuisance tripping.

The Breaker Trips with Nothing Plugged in

A breaker tripping with nothing plugged in occurs when a hot, neutral wire is touching somewhere in the circuit. The common causes include frayed or damaged electrical wires, loose connections, faulty electrical receptacles, light switches , or dimmers.

Electrical wire damage happens when:

  • wiring is chewed by animals such as rats, squirrels , raccoons, etc
  • wire sheathing and insulation ages and become frayed
  • wires rub against sharp edges such as punch-outs with missing grommets or wire clamps

Loose connections often occur when electrical wire nuts come loose or electrical tape wears out causing wires to touch.

Defective wiring can be anywhere along the circuit, so it’s best to contact a licensed electrician to troubleshoot why the breaker is tripping.

Replacing a Bad Circuit Breaker

  • Check the electrical panel to see the compatible approved circuit breaker brands. Also, make a note of the brand of the electric panel . This is to help you determine if there are upgrades they could recommend for the hardware.
  • Order online or go to the hardware store and purchase the breaker of the same voltage as the one you are replacing.
  • Go and open the electrical box and switch off the bad breaker. Loosen the terminals and remove the wires using a pair of needle-nosed pliers. Ensure the pliers have rubber insulated handles to avoid shock or electrocution since you will use the pliers to grab the live wires from the terminal. That is a safety measure.
  • Remove the bad breaker. Replace it with the new breaker and slip its clips into place. Remember to switch off the replacement breaker.
  • Next, using the pliers, hold the wiring and tighten the screws on the terminal. It is crucial to ensure that the wires and screws in the terminals are in the right place.
  • Turn the breaker on and replace the electrical panel cover.

Can a Breaker Fail Without Tipping

If you have a newer electrical panel , it’s not likely for a breaker to fail and not trip. However, in older breaker boxes like Federal Pacific , the breaker failing to trip is common.

The main reason Federal Pacific was investigated by the Consumer Products Safety Commission (CPSC) was widespread structure fires involving breakers failing to trip when an electrical overload was present. They found that the circuit breaker contacts would fuse to the bus bar.

Modern breakers will trip when a failure occurs as an added layer of safety. Most older breakers did not have these safeguards.

With AFCI breakers, if the Internal sensing mechanism fails, the breaker reverts to a standard breaker. The AFCI sensor mechanism will no longer work, but the breaker would still trip from overcurrent protection. Therefore, you should test the AFCI breaker regularly.

Conclusion 

Listen to your circuit breaker . It’s alerting you of a problem when it trips. That communication could be a problem with the breaker itself, the circuit, or the amount of electric current coming into your home.

How to Fix a Tripped Circuit Breaker That Won’t Reset

An old, damaged circuit breaker that keeps tripping.

  • July 5, 2024
  • Electrical Tips

Have you ever had a circuit breaker trip and found that it won’t reset? It’s a common problem, and one that can be frustrating when you’re not sure what to do.

The most common reasons for a circuit breakers that won’t reset are:

  • Damaged breakers
  • Electrical shorts
  • Loose wiring
  • Damaged insulation

As the top reviewed residential and commercial electrician in our area , we’ll walk you through how to check for each of these common reasons, and discuss how to fix them.

Why circuit breakers trip

A circuit breaker is a safety device in your home designed to stop the flow of electricity if there’s an overload, which can help prevent fires. When the current flowing through the circuit breaker becomes too much for it to handle, it “trips” and shuts off the power to prevent a fire from starting.

Most of the time, resetting a tripped circuit breaker is a simple matter of flipping the switch back to the “on” position. However, sometimes the breaker won’t reset no matter how many times you flip it.

First, try to reset the tripped circuit breaker

First, we should perform a basic test to make sure the breaker is actually malfunctioning. If you haven’t already tried manually resetting the circuit breaker, this is the place to start.

Locate your circuit breaker box and open the cover. Once you’ve located the tripped breaker, flip it to the “Off” position. Then, flip it back to the “On” position. You should hear a click as the breaker resets. If the breaker trips again, or simply won’t reset, there may be a problem with your wiring.

How to fix a tripping circuit breaker

Check to see if the circuit breaker is damaged.

If the circuit breaker trips and won’t reset, the first thing you should do is check to see if the switch is damaged. Circuit breakers are designed to trip when they become overloaded, which means they’re also designed to be flipped back on when the overload is resolved. However, if the switch itself is damaged or the electrical panel is outdated , it may not reset properly.

To check for damage, first make sure that there’s no power going to the breaker box by flipping all the switches to the “off” position. Then open up the panel and visually inspect the faulty breaker for any signs of burned or blackened areas. If you see any charring or burning around the switch, it’s likely time to replace it.

In some cases, you may be able to reset a damaged breaker by gently bending the switch back into place. However, this is only a temporary fix and the breaker will eventually need to be replaced.

We recommend that if you see any damage, it’s best to replace the entire circuit breaker rather than just the switch.

Check to see if there’s an electrical short

Another reason why your circuit breaker won’t reset after tripping is because there’s an electrical short somewhere in your home. An electrical short occurs when there’s too much current flowing through a wire, causing it to overheat and potentially start a fire.

To figure out if there’s an electrical short, the first thing you should do is turn off all of the switches in your breaker box. Once everything is off, go around your home and look for any signs of an electrical fire, such as burning smells or smoke. If you see or smell anything suspicious, call a licensed electrician right away.

If you don’t see any signs of a fire, the next step is to identify which circuit is causing the problem. Start by flipping on one switch at a time and seeing if the breaker trips. If it does, leave that switch off and move on to the next one. Repeat this process until you’ve found the problem circuit.

Once you’ve identified the problem circuit, the next step is to figure out where the electrical short is located. The easiest way to do this is to start at the breaker box and work your way down the circuit until you find the problem.

If you’ve followed these steps and you believe there may be an electrical short, it’s important to call an electrician right away. They’ll be able to locate the source of the problem and fix it before it causes any further damage.

Check for loose wiring

Another common reason for a circuit breaker to trip is because of loose wiring. Over time, wires can loosen and become frayed, which can cause them to short circuit.

The best way to check for loose wiring is to listen to your devices and appliances for the sound of buzzing or crackling. One common culprit is buzzing light switches or outlets. If you don’t find a faulty appliance, note that this can also be true around the breaker.

If you hear these noises and suspect that your circuit breaker is tripping because of loose wiring, the best thing to do is call an electrician as soon as possible. Trying to fix the problem yourself could result in injury or even death.

An electrician will be able to quickly diagnose the problem and make the necessary repairs. In most cases, they’ll also be able to prevent the problem from happening again in the future.

Look for signs of corrosion

Another common reason for a circuit breaker to trip is corrosion. This is especially true if you notice any moisture or wetness in the electrical panel . Corrosion can cause the metal parts of the breaker to break down, which in turn can cause a short circuit.

Corrosion usually appears in the form of a white, chalky substance building up around screw terminals. Look for signs of corrosion, rust, or moisture around the circuit breaker.

If you suspect that corrosion is the culprit, call an electrician to have a look at the problem. Trying to clean or repair the corrosion yourself could result in serious injury.

Check for damaged insulation

Sometimes circuit breakers will have insulation around them to stop cold air from entering through the box itself. Damaged insulation is another common cause of tripped circuit breakers. If you have insulation around the box, inspect it to see if it looks damaged.

If the insulation around your electrical wiring is damaged, it could cause a short circuit. Once again, if you suspect that this is the problem, call an electrician rather than trying to repair the problem yourself.

Is it dangerous if a circuit breaker keeps tripping?

We are often asked if tripping circuit breakers are dangerous. If your circuit breaker keeps tripping, it could be a sign of an electrical problem in your home, up to and including serious fire risks. While it’s not necessarily dangerous if your circuit breaker trips occasionally, if it happens frequently, it should be fixed right away.

If your circuit breaker trips and won’t reset, don’t panic! Many times the problem is something minor that you can easily fix yourself. However, if you’re unsure of what to do or think the problem may be something more serious, always err on the side of caution and call an electrician . Trying to fix the problem yourself could result in serious injury or even death.

Resetting a tripped circuit breaker is a relatively simple process that most people can do on their own. However, if the breaker trips repeatedly or if you have any questions about your electrical system, it’s always best to contact a professional electrician for assistance.

If you have any questions about resetting your circuit breaker or if you need assistance from a professional, don’t hesitate to contact us . We’re here to help!

what trips a circuit breaker

Resetting Circuit Breakers – What Every Homeowner Should Know

Knowing the basics when it comes to electricity can go a long way in helping keep your family and home safe. One often misunderstood aspect of home electricity is circuit breakers and what to do when they ‘trip’. Here’s a quick, informative overview to help keep you safe.

The Fundamental Role of a Circuit Breaker

The home circuit breaker was invented nearly a century ago. However, it wasn’t until the 1960s that they began to be broadly adopted instead of traditional fuses. The number of circuits in a home can vary greatly, depending on the year built and the size of the home. When a circuit breaker senses that a circuit is drawing too much power, it ‘trips,’ automatically shutting off power to the circuit.

Importantly , faults that result in a tripped circuit breaker are NOT typically what cause electrical fires since the breaker did its job and stopped the flow of electricity before a fire could start. However, electrical fires (nearly 50,000 each year in the U.S. alone) most often start from faults that do NOT trip traditional circuit breakers – and this is why Ting was created.

Each breaker has a rating that determines how much current it can safely carry and interrupt. Circuit breakers that feed receptacles (outlets) are rated at 15 or 20 amps, and will automatically trip if current exceeds these ratings. Lighting circuits are typically on circuits protected by 15 amp breakers. In addition to these, your electrical panel will also contain a limited number of larger “double-pole” breakers that have higher amp ratings for big appliances like air conditioners, water heaters, stoves and clothes dryers.

Does Ting generate an alert when a breaker trips?

When a breaker trips, it fulfills its role of keeping your home safe. Ting does not alert on the actual ‘tripping’ of the circuit breaker. However, depending on the root cause, Ting may alert on underlying conditions that led the circuit breaker to trip. We’ll cover those situations below.

What Causes a Circuit Breaker to Trip

Breakers can trip for a few reasons but with the same purpose in mind – to keep you safe. So be mindful if you’re planning to reset the breaker. Here’s how to know when it is safe or not.

(1) Overloaded Circuit

The most common cause of a circuit breaker tripping is too much current being drawn by lighting, devices or appliances on a given circuit, overloading it. Overloading wiring in a circuit generates immense heat, which can cause a fire.

Is it safe to reset the breaker when it tripped from an overloaded circuit?   Depending on the age and design of your home, overloads can be somewhat common but normally easy to pinpoint. If a breaker tripped when on the initial use of an appliance or light, it is possible that is what overloaded it. In this situation, unplug some items to reduce the load on the circuit – then reset the circuit breaker. If it trips immediately or soon thereafter, this means you are likely facing with a more serious problem than an overload.

Does Ting alert on overloaded circuits?

Ting does not detect that a circuit is “overloaded.” However, Ting does notify and warn of low voltage conditions that can occur from an overload.

(2) Short Circuit

The wiring in your home consists of three different types of wires: a live or hot wire, a neutral wire, and a ground wire. When a live wire comes into contact with the neutral wire, a ‘short’ occurs, allowing a lot of current to flow and overload the circuit. Short circuits are generally a much bigger problem than a circuit overload, as they can potentially create a risk of both fires and electrocution. A specific type of short circuit, a ground fault surge, occurs when the hot wire touches either the ground wire or a metal electrical box that the ground wire is connected to. Ground fault surges can potentially be even more dangerous than short circuits and cause electrocution. GFCI protection of certain outlets in the home has been required by code since the 1970s.

Is it safe to repeatedly reset the breaker if it keeps tripping from a short circuit? The short answer, excuse the pun, is no . Repeatedly resetting a breaker could result in an arc flash or a fire (see the recent news story below). If the circuit is not overloaded and the breaker trips after one attempt at resetting it, leave it in the tripped state. It is essential that you contact a professional electrician to determine the source of the problem.

News Story – House Fire On 2/23/2023 in Kennewick, WA a home experienced an electrical fire in the attic .  The homeowner reported to the fire department that the circuit breaker tripped multiple times and was reset each time before they smelled smoke in the home.  Repeatedly resetting a tripped circuit breaker is NEVER safe. Thankfully there were no injuries from this fire.

Does Ting alert on short circuits?

If a short circuit trips a circuit breaker, Ting would likely sense the very brief arc associated with the short but would not alert on this fault.

By design, a short circuit should always cause a breaker to trip. It is important to remember that while it is a very brief event, a short circuit might also cause sparks, popping sounds, and possibly some smoke, despite the breaker safely tripping to shut off electricity for the circuit.

(3) Old or Faulty Circuit Breakers

Though not nearly as common as the above causes, a circuit breaker might trip – not due to a problem with the circuit – but with the breaker itself. If your breaker or your electrical panel is old, faulty, or not wired properly, it can also cause the breakers to trip. Remember, repeatedly resetting a breaker could result in an arc flash or a fire. If the circuit is not overloaded and the breaker trips after one attempt at resetting it, leave it in the tripped state. It is essential that you contact a professional electrician to determine the source of the problem.

On the other hand, outdated breaker boxes can have worn connectors, and a breaker may not trip when it should, which can cause a circuit to overload and start an electrical fire.

Trust Your Instincts

When in doubt, call a pro. Don’t try and reset a breaker if it trips again after resetting it once. It is essential that you contact a professional electrician to determine the source of the problem.

What’s Tripping My Circuit Breaker? 4 Possible Causes

As electricity flows through the wiring in your house,  circuit breakers  serve as critical safety devices that prevent overloads. When too many amps of electricity are pulled into a circuit, both damage and danger result. Wiring can overheat and melt insulation, causing a fire.

A circuit breaker is a more modern, reusable version of a fuse. The breaker constantly monitors the flow of electricity into a circuit, and if for any reason the amperage exceeds the circuit’s rated amount, the breaker trips and the flow of electricity is interrupted at the breaker panel. All outlets on that individual circuit and all devices plugged into it are instantly powerless.

How Much Load Is Too Much?

In a typical residence, circuits in living spaces like bedrooms and family rooms are generally rated for 15 amps. Parts of the home where more amperage is used such as the kitchen or laundry room will be controlled by more heavy-duty circuit breakers rated for 20 amps. Certain high-demand appliances, electric water heaters and central HVAC equipment will typically occupy an individual dedicated circuit and are rated for 30 to 50 amps.

While a tripping breaker is an important safety feature, it can be an annoyance as well, particularly if it happens often. A breaker that trips repeatedly is telling you something important about your home’s electrical circuitry or devices connected to it. Repeated breaker trips should never be simply reset and ignored.

Here are four common causes for a tripped circuit breaker.

Circuit Overload

A circuit overload, which is the most common cause of a breaker trip, occurs when a device plugged into the circuit demands more amperage of electricity than the circuit is rated to supply. This may occur because too many devices are already drawing current on that circuit and the circuit has reached its maximum rated capacity.

The remedy for circuit overload is to re-distribute the load more evenly by plugging some devices into other circuits.

Appliance Issues

Another may occur when a single electrical device draws excessive amps due to an internal malfunction or defect. For example, the electric motor incorporated in an air conditioner compressor may overheat due to internal wear and may pull too many amps. Or a heater or stove that utilizes electric resistance coils to produce heat may begin to cause overloads.

When a single device or component is causing breaker trips, it must be disconnected from the circuit and evaluated to isolate the problem. Repair or replacement of the device is required before it can be plugged back in and utilized safely.

Short Circuiting

A circuit short occurs when an insulated portion of the black “hot” wire physically contacts another black wire or a white neutral wire. This sends a surge of amperage into the circuit that causes the circuit breaker to trip instantaneously.

Short circuits may occur when household wiring degrades due to age and insulation frays or cracks, allowing bare wires to come in contact. Or it may be caused by an internal defect in any device that’s plugged into an outlet on the circuit.

Short circuits should be tracked to their source by looking for any discolored outlets, melted or cracked power cords or any devices that malfunction or emit a smell of burning wire. If obvious external causes can’t be readily identified, the problem is likely within the wiring itself. Leave the breaker switch off and contact a  professional electrician  to trace the problem.

Ground Fault

A ground fault happens when the hot wire in circuit contact either a ground wire or a grounded metal component such as the metal outlet box. A ground fault is simply another version of a short circuit that causes an electrical overload which triggers the breaker to trip in response.

Pinpointing and correcting a ground fault can be done by a qualified electrician using equipment specifically designed to troubleshoot circuitry.

what trips a circuit breaker

6 Reasons Your Circuit Breaker Keeps Tripping

Circuit breakers are indispensable components of your electrical system. The device will shut off when it detects a short circuit, an overload, or a power surge. It is common for the breaker to trip once in a while, but if it keeps tripping, it could be due to one of the the following issues.

1. Your Electrical System Has a Short Circuit

One common reason your circuit breaker keeps tripping is a short circuit. The simplest definition of a short circuit is contact between the neutral and the live wires. When the wires touch, it can cause your circuit breaker to trip immediately after turning it on.

Contact between the live and neutral wires will cause a sudden flow in current. The wires can overheat and may start a fire. A discolored receptacle or a burning smell are symptoms of a fault in the circuit.

The short circuit could also be in the appliance rather than the electrical system. You can identify the source of the problem by turning off all the electronics on the circuit. Switch them on one at a time until you find the appliance tripping the breaker.

It is advisable to remove the appliance or have an electrician troubleshoot the circuit. You could cause further damage to your equipment or risk electrocution. Consider consulting our electricians at Huft Home Services in Sacramento for prompt electrical service.

2. The Circuit Is Overloaded

Circuit overloading occurs when an electrical load exceeds the rating of your electrical system. The breaker will trip when it detects a current greater than the circuit’s rated value. Without the breaker, the wires will overheat and start a fire.

Burning smells, warm receptacles, or discoloration on switches could be signs of a circuit overload. You may notice lights dimming when you turn on an appliance. It means the circuit has insufficient amperage to power your equipment.

For example, if the lights flicker when you turn on the microwave, the circuit will need an upgrade. Also, connecting multiple devices could exceed the amperage of the electrical system. You could move some of the devices to another outlet.

You can also reduce the circuit’s load by using LED bulbs rather than incandescent ones. Avoid using extension cords excessively. A better long-term solution is to upgrade the electrical system to suit your lifestyle and energy needs.

You may need a 20-amp circuit in your workshop for your power tools. An aging vacuum cleaner or oven may draw more power from your electrical system as it becomes inefficient. If you are unsure of the cause of the problem, reach out to our electrical team.

3. Power Surges and Arc Faults

A power surge is a sudden spike in voltage. The voltage can vary from a minor increase to a considerable voltage spike that can damage appliances and valuable equipment. Even small increases can cause your electronics to fail gradually over time.

Sometimes lightning may cause a surge in your electrical system. A direct strike on the power line will trigger a voltage spike.

A power surge can also occur after an outage. When the electricity is restored, there is a jolt in the voltage. You can unplug all devices during severe storms to eliminate the risk of equipment failure.

The best way to protect your electronics is to use a surge protector. Many point-of-use surge protectors resemble extension cords, but it is worth noting not all extension cords are surge protectors.

A point-of-use surge protector is affordable and suited for powering one or two appliances. However, you could opt for a whole-house surge protector. A whole-house surge protector will keep your electrical system safe regardless of the source of the voltage spike.

4. Ground Faults and Electrocution Hazards

A ground fault is when the current takes an unintended path to the ground. It occurs when the live wire touches the appliance’s outer casing or ground wire. Electricians consider ground faults to be another type of short circuit since there is a bypass across the wiring.

As with short circuits, ground faults will reduce the resistance in the conductor. A lower resistance can allow the uncontrolled flow of current. Your circuit breaker will repeatedly trip if there is a ground fault in your electrical system.

The principal risk of a ground fault is an electrocution hazard. Touching an exposed wire can create a path of least resistance to the ground. Damp conditions can increase the risk of a ground fault and electrocution.

The NEC (National Electrical Code) requires GFCI (Ground Fault Circuit Interrupter) outlets in the kitchen, bathroom, or outdoors. A GFCI outlet constantly monitors the voltage in the hot and neutral wires. When there is contact between the hot and ground wire, the device stops the current.

A ground fault could also occur due to wiring faults during installation. Reversing the polarity of the live and neutral wire in an outlet can cause a shock or short circuit. Reverse polarity allows electricity to continue flowing into the appliance even when off.

A GFCI circuit can detect changes in power faster than a regular circuit breaker. Its primary role is to protect you and your family from electrocution. You can count on Huft Home Services for electrical solutions to keep your Sacramento home safe.

5. Breaker Trips Due to Outdated Wiring

Outdated wiring in your home could be another reason the circuit breaker keeps tripping. Older homes have electrical systems that cannot handle the electrical demands of a modern household. You can overload the circuit or trigger a fire by using the latest energy-demanding appliances.

One of the issues with outdated circuits is the absence of grounding connections. If you have two-pronged receptacles in your home, you may want to upgrade to a three-pronged outlet. The lack of a grounding slot can increase the risk of appliance damage or electrocution.

Aluminum wires in outdated electrical systems can melt due to circuit overloading. The plastic casing also increases the risk of a fire when it burns.

Additionally, deteriorating insulation on the conductor can trigger a ground fault. According to statistics, 90% of ground faults are caused by deteriorating insulation on wires and appliance cables.

6. Outdated or Worn Circuit Breaker

A circuit breaker can trip due to a loss of efficiency or a manufacturer’s defect. In such instances, the breaker may shut off the power even without the occurrence of a short circuit or overloading.

If your circuit breaker keeps tripping, schedule an electrical inspection. It is advisable to avoid tinkering with the breaker panel on your own. Consider consulting a certified electrician to prevent electrocution, fires, or appliance damage.

Certified electricians can pinpoint the problem in the shortest time possible. Professionals have the requisite training to handle complex and risky electrical projects. You can work with our team to plan an electrical system that suits your needs.

What Does a Circuit Breaker Tripping Mean?

 when there's a circuit breaker tripping, it can indicate that the circuit breaker detects an electrical issue, and it shouldn't be ignored..

circuit breaker tripping

The pandemic-induced surge in home electricity use is real. Consider that, according to the National Bureau of Economic Research, American spending on  home power consump tion  skyrocketed by $6 billion! 

With more usage comes more problems, and circuit breaker issues are among the most common. When there's a circuit breaker tripping, it can indicate that the circuit breaker detects an electrical issue, and it shouldn't be ignored.

 Circuit Breaker Tripping 101

Most circuit breaker issues center around circuit overload. Circuit breakers are a vital part of your home's electrical system since they are designed to prevent costly and damaging surges in electrical current. 

The breaker, working in tandem with a fuse, serves as an electrical unit's internal sensing mechanism. At the slightest sense of excess current, the circuit breaker will "trip," triggering a cease in all electrical activity within the circuit.

Not only can such a smart mechanism help with preventing damage to wires and other electrical components, but circuit breakers can also save lives by preventing electrical fires. According to the National Fire Protection Association,  electrical failures  were the second leading cause of home fires between 2012-2016.

So why do circuit breakers trip? Here are the three most common reasons for circuit breaker tripping and how you can go about fixing a circuit breaker.

 1) Circuit Overload

By far, the m ost common reason a circuit trips is because it's overloaded. Even running a circuit at its electrical capacity can cause home appliances to burn out or a circuit to trip. Ideally, you want to run a circuit below its capacity to keep it from tripping and to prevent any damage from occurring. 

The most familiar example of circuit overload is an over-stuffed power outlet. When you have a dozen gadgets all demanding electrical current to work, eventually that single outlet's capacity will experience overload, and the circuit will trip.

Knowing what each electrical outlet in your house can handle is key to preventing circuit overload. Even a single high-current appliance like a washing machine cannot plug into just any outlet.  Understanding your power outlets  is critical for a safer home.

Before you head to your circuit breaker box or call your electrician, notice what was plugged in at the outlet where the tripped circuit occurred. You may have overloaded it.

 2) Short Circuit

Similar to an overload, when a circuit "shorts," it responds to more current than it can bear. But a short circuit is far more dangerous. 

A short circuit occurs when a "hot" or active wire comes into contact with either another active wire or a neutral wire. The touching wires cause a spike in current that can likewise trip your circuit breaker. Most often, the causes for short circuits are mechanical issues like: 

  • Loose Connections
  • Improper Wiring
  • Damaged Wires

Faulty components, like switches, plugs, cords, appliances, or lighting fixtures, are often culprits of short circuits. Short circuits can occur if you screw or nail into drywall and penetrate an electrical wire.

Remember that short circuits may involve faulty circuit wiring, but the device you're plugging in can cause the problem as well. Keep this in mind, especially if you're using older devices or gadgets that have been out of commission for years, as these can be more prone to short circuits, independent of what's going on in the outlet.

Due to their volatile nature, short circuits are some of the biggest causes of electrical fires, so be extra attentive and don't hesitate to call a professional. As a general rule, most people should never  DIY electrical issues  in their homes.

 3) Ground Fault Surge

 Ground fault surges are similar to short circuits because they involve a sudden spike in current, creating an overload. Ground faults occur when an active wire comes into contact with the ground wire. The contact can come directly or indirectly via the metal housing that connects to the ground wire. 

Copper grounding wires are especially prone to ground fault surges. Copper is the most  conductive material  in everyday use when it comes to home electrical systems. When a hot wire touches the ground wire's copper coating, it results in superconductivity that overwhelms the circuit. A similar result can come from an active wire touching a ground's metal outlet box. 

 Understanding and Fixing Circuit Breaker Issues

So how should you go about troubleshooting a circuit breaker issue? Even though you should leave anything remotely technical to a professional, there are a few things you can do to investigate circuit breaker trip meaning.

First thing's first. Make sure you and your family are safe. Check for signs of excess heat or burning—smell for what could be smoke from an electrical fire. If you sense any signs of a fire, evacuate and call 911.

Check for any discoloration around an outlet. Also, make a note of any sparks or popping noises coming from the outlet. Any of these could be a sign of a ground fault surge or a short, in which case simply flipping the circuit breaker switch won't help. And remember, the older the outlet, the more likely it is to experience problems.

Look for any signs of damage to your devices. Remember that the problem could be coming, not from your home's outlet, but from what you plugged in.

If there are no signs of a blown circuit, try going to your circuit breaker service panel. You may be familiar with this metal box, often located in a garage or utility room. Flip the switch of the house area that tripped, and see if that "resets" the circuit. 

 Fixing a Circuit Breaker

If a simple flipping of the switch doesn't work, it's time to call a professional electrician. The seasoned team at Buell Electric can assess the problem and fix a circuit breaker, which may involve repairs or upgrades. 

Circuit breaker tripping may be as innocent as overloading an outlet, but it can point to more serious problems as well. The best way to know for sure is to  contact us  today.

Why Does My Circuit Breaker Keep Tripping and How to Fix It?

Blog Image

When you notice that the circuit breaker is tripping the first time, it is easy to not worry about this at all. But the more times that this happens, the easier it is to see it as a big problem. Outside of being annoying, it could be a sign that something is wrong with your system. 

Working out the exact reason why your circuit continues to trip is a challenge. However, if you know where to look and what may be causing the problem can really make a difference. Some of the reasons why your circuit breaker is tripping and some of the steps you can take to fix this problem include:

Why is My Circuit Breaker Tripping?

There are different reasons why your circuit breaker may be struggling and tripping. This can happen on occasion, but if it does it often, it is a sign that something is wrong. Some of the most common reasons a circuit breaker is tripping includes:

1.     The Circuits are Overloaded

The reason this is called a circuit breaker is that it is designed to break up the circuit when too much current tries to run through. For example, if your circuit is designed to be 20 amps and you are running 30 amps to it, the breaker is going to stop this and trip in an effort to keep the home safe . 

Often we try to plug too many things into the same circuit. This causes it to overload and will make it hard to protect your home. The circuit breakers will do their best and can trip to do this. 

2.     You Need to Do a Heavy-Up

Sometimes it is hard to know how much the circuit is able to take or how much your appliances are sending over to the circuit. You may find that the appliance is running way higher than you expected and this can cause the circuit to trip. If this is the cause, it may be time to do a heavy-up.

To keep it simple, a heavy-up is a way to increase the amperage that comes into the home at your service panel. This allows you to upgrade your circuit breakers and electrical system to receive and handle more energy at the same time. If you do this, be prepared for the whole service panel to get replaced with this. 

3.     The Circuits are Shorting

This could be a serious problem because it relates back to the wiring in the home. There are several wires that are attached to the outlet. When the wires get close enough for two hot wires to touch each other, or a hot wire is able to touch a neutral wire, this causes the circuits to trip. 

If this is the main problem with your circuit breaker, then it is important to get someone over to take a look. It will not fix itself and could lead to a lot of damage from a fire inside the home. 

4.     You Have a Ground Fault

A ground fault will sometimes happen when a hot wire is touching something it shouldn’t, but this time it is touching the metal outlet box. This can be dangerous too and you need to get a professional over to see what is going on and see what your options are to fix it. 

5.     Faulty Appliances or Bad Wiring

If something is wrong with your appliances or the wiring is not doing well in your home, then this can be enough to make your circuits stop working well. A faulty appliance can cause a circuit over and over again. When this is the case, you should consider replacing the appliance to keep things safe. 

If one of your outlets has not been wired well, then it may be enough to make the breaker trip. If you get the same results out of one particular outlet, even when you try to fix it, then a qualified electrician needs to take a look at it for you. 

How to Fix Circuit Breakers That Trip

When a circuit breaker trips once or twice, then it is usually not a big deal. This is a sign that there was a surge to the system and it was able to keep your appliances safe. This is what the system is meant to do. When the circuit breaker seems to trip over and over again, then this is a sign that you need to make some changes. 

If you have a circuit breaker that seems to trip many times, then there are a few things you are able to do. Often the problem is that too many things are plugged into the same circuit. By unplugging a few of them, you may be able to fix it all. 

If you are researching some of the potential issues and notice that only one appliance is making this happen, then unplug that one and add something else there. If you can do this without the circuit tripping, this means that you need to replace that appliance. 

In some cases, the issue is going to be from old wiring in your home. Even if it was installed right, there is the potential that it has just gotten old. When this is the case, it is time to call in an electrician to check the wiring and see what is causing the issue. They can help get the wiring up to code to keep you safe. 

Taking Care of Your Circuit Breaker

The circuit breaker in your home is an important component. You want to make sure that it is taken care of to ensure all your electricity and appliances always work, without causing damage to the home. When the circuits start to trip, it is a sign that something is wrong. 

There are many reasons why your circuit breakers are struggling with tripping and running into problems. When you notice some of the issues above, it is time to take care of the circuits and make sure they get fixed early on.
