Why is My Arc Fault Breaker Tripping?

Why Arc Fault Breakers Keep Tripping

When you plug a cord into an electrical outlet, you expect the device to power up immediately and without issue. While this happens most of the time, there are instances when the power shuts off in another area of your home. This is typically due to an arc fault circuit breaker that has tripped. Resetting the breaker is generally a fast and easy solution, but if the situation happens again, you need to take a closer look at what is going on. Many causes of a tripped arc fault circuit breaker have potentially dangerous consequences, so they need to be diagnosed and repaired quickly.

About Arc Fault Circuit Breakers

Another name for an arc fault circuit breaker is arc fault circuit interrupter, which is shortened to AFCI. The purpose of the AFCI is to monitor electricity consumption and respond to a detected electrical arc. Sparks are often present with an electrical arc, and these sparks can lead to a fire. When the AFCI trips, power is cut to the outlet, and the danger is prevented.

What Makes Arc Fault Circuit Breakers Trip?

Arc fault circuit breakers detect electrical arcs that have potentially damaging and dangerous outcomes. Electrical arcs are caused by several factors. It is important to understand these factors so that you can take proper action to prevent serious outcomes from the electrical arc.

Excessive Power Demand

Power cords make it easy to expand the functionality of your power outlet by adding more sockets. However, power outlets have an amperage limit, and adding more sockets can result in excessive power demand. When too much energy is running through the outlet, the AFCI will be tripped. If you identify this as the cause of your issue, you can request installation service for a few new power outlets to safely meet your needs for electricity.

Devices That Are Not AFCI-Compatible

Generally, the various electronic devices and appliances on the market today are compliant with AFCIs. However, if you plug older equipment that is not AFCI compliant into an outlet, the result may be a tripped breaker. If this happens regularly, it may be time to upgrade to more modern appliances and devices.

Device and Cord Damage

For electricity to flow properly into a device, both the device and its cord must be in good condition. A common sign that a cord or the device is damaged is a spark when the cord is plugged into the wall. This spark may be followed by a tripped AFCI. A spark comes with the risk of electrocution or a house fire, so the device and the cord should be thoroughly inspected for damage before they are used.

Improper Socket Connection

The socket should maintain a secure grip on the plug’s prongs at all times. When the connection is loose, the plug will dangle at an angle from the socket. Often, the device may still power up, making this a problem that is easy to ignore. However, an improper connection can lead to overheating as well as a breaker that trips frequently.

Bad Wiring

In some instances, wiring is installed incorrectly, such as if it is exposed or loose. Even if the wiring is installed correctly, it can be damaged. For example, you could unintentionally put a nail through a wire while hanging a picture, or a rodent could gnaw through a wire. These issues often produce an electrical arc that causes the circuit breaker to trip. Bad wiring is a common cause of house fires, so this issue requires urgent attention.

How to Diagnose the Problem

To determine what is causing your AFCI to trip, you need to consider issues with the cords, devices, outlet and wiring. To check your devices, remove all plugs from the outlet, and turn out the lights. After resetting the breaker, plug the cords back into the outlet one at a time. As you do, inspect the cords for fraying or other signs of damage. Look at how securely the socket grips the plug. In addition, search for wording on the cord that indicates it is AFCI compliant.

If you determine that a cord or device is causing the issue, you can remedy the problem yourself relatively easily. However, if you find that the devices and cords are not to blame, a professional diagnostic service for the wires and outlet is in order. Your licensed electrician can determine the cause and repair the damage.
