Why Is My Arc Fault Breaker Tripping?

Plugging a cord into a power outlet should not shut off power to another device or area of the home. However, this is a frustratingly common event. The most common cause is a tripped arc fault circuit breaker. It is easy to reset the circuit breaker and continue on with your day, but this is an issue that requires a closer look. Some causes of a tripped arc fault circuit breaker have potentially hazardous risks, so you need to investigate the cause and fix the problem right away.

What Does an Arc Fault Circuit Breaker Do?

Arc fault circuit breaker is often abbreviated as AFCI, which is an acronym for arc fault circuit interrupter. The AFCI’s job is to monitor the amperage for an electrical arc. With an electrical arc, sparks are common, and the result could be a house fire. The arc fault circuit breaker trips to counter the electrical arc and prevent a dangerous situation.

Reasons Why an Arc Fault Breaker Trips

Electrical arcs are generated by several issues. It is important to understand what these causes are so that you know what type of corrective action to take.

High Energy Demand

The typical electrical outlet has ports for two plugs. However, people often use power strips to add more functionality to the outlet with extra ports. Sometimes, this results in the outlet’s amperage limit being breached, and this creates an electrical arc and overheating. An alternative to using power strips is to schedule the installation of additional power outlets to accommodate your needs.

Incompatible Devices

The appliances and various electronic devices sold today are designed to accommodate today’s outlets. Older equipment, however, can create an electrical arc and trip the breaker. The primary solution to deal with this problem is to replace older equipment with newer models that are compatible with today’s outlets.

Damaged Power Cords and Devices

When an electrical cord is frayed or a device is damaged in other ways, you may notice a spark when you plug in the cord. This power surge can trip the AFCI. Because of the risk of a fire or electrocution, damaged devices and cords should not be used.

A Loose Connection

Have you noticed that your power outlet does not grip onto the plug as well as it should? When this happens, the plug slips out of the socket by a small amount. The electrical device may still work, however, so you could simply ignore the issue and use the device as desired. However, this often results in overheating as well as an electrical arc and a tripped breaker.

Wiring Issues

Wiring issues can be present from the time of installation, or they can develop. If wiring is not installed correctly, it could be loose or exposed. Both of these problems can cause a tripped circuit breaker. If the wiring has been damaged in the wall, such as from rodent damage, the arc fault circuit breaker may also trip.

Diagnosing Your Tripped Arc Fault Breaker

With several causes of a tripped breaker, it is critical to understand the cause before you take action. In some instances, the issue can be remedied on your own by making a few simple changes. Other issues, however, should only be addressed by a licensed electrician.

The first step to take when diagnosing the problem is to turn off the lights and remove all plugs from the outlet. Then, reset the AFCI, and plug each plug into the outlet one by one. This is a way of checking to see if one device is the problem. While inspecting the devices individually, look for frayed or damaged cords and pay attention to how secure the plug’s connection is to the socket. In addition, inspect the devices to confirm that they are AFCI compatible.

If you do not notice any issues with the cords and devices, the outlet itself or the wiring could be problematic. These issues should only be diagnosed and fixed by an electrician. The electrician will complete the repairs safely and ensure that they are done to code.
