Why Is My Arc Fault Breaker Tripping?

An arc-fault circuit interrupter (AFCI), also referred to as an arc fault breaker, is a safety device meant to respond, detect and guard against any faulty connections that cause sparking or arcing. Although this is definitely a good safety measure, AFCIs are also prone to tripping. It’s not usually a big deal if it happens sporadically. However, it’s best to read the following info so that your Daytona Beach, FL, home doesn’t end up suffering from an electrical fire.

What Makes My AFCI Trip?

Your arc fault is an important device. After all, it gives you ample warning about slow electrical leaks. Without it, you wouldn’t usually be able to detect high-intensity heating in your electrical wires. By tripping, the AFCI cuts off the power before it can lead to a fire. When your AFCI malfunctions, it can cause a whole host of problems.

Damaged Arc Fault Breaker

A damaged arc fault breaker, or AFCI, is caused by having multiple circuit overloads and resets. This can cause your AFCI to have a false trip. Additionally, an outdated or damaged AFCI may stop working properly, which will lead to the inconvenience of regular false trips.

Broken Insulation

The circuit has insulation to keep it safe. Whenever this becomes compromised by physical damage and/or rodent damage, it’ll cause your AFCI to trip.

Wear and Age

The older your electrical wires become, the more likely they are to deteriorate or become corroded. As your wires age, they’ll become increasingly brittle until they crack, which results in a voltage leak. If this is left undetected for long enough, it’ll cause an electric arc, and your arc fault breaker will trip.

Mold or Dampness

Any type of dampness can lead to mold. Plus, the moisture around your wires can lead to a short circuit. Yet again, this will ultimately cause your AFCI to trip.

Loose or Poor Connections

Whether you’ve got exposed conductors, damaged insulation, or loose wires, it’ll allow a higher than usual amount of electrical current to go through the circuit. As you’ve probably guessed, this can cause your arc fault breaker to trip.

What if the wires aren’t properly connected to the AFCI breaker? This can cause a false trip due to the AFCI’s internal sensors being unable to detect appropriate arc patterns. It’s also important to note that a poor breaker connection can lead to overheating, thereby triggering a trip.

Circuits Are Overloaded

Your AFCI may deal with an overload trip if the circuit ends up carrying a higher level of power than it was meant to. For example, it’s common to overload your circuits by connecting large electrical devices to a circuit that simply doesn’t produce enough power. In this way, your AFCI works just like other circuit breakers. When the demand for power elevates beyond your circuit’s power supply, it’ll make your AFCI trip.

Incompatibility with Devices

Finally, we’ve reached one of the most common issues an arc fault breaker can face. Incompatibility with devices and appliances such as treadmills, heaters, power tools, microwaves, or fluorescent lighting can produce mechanical arc patterns. Your AFCI often interprets this as a dangerous arc, which causes it to trip.

How Can You Avoid AFCI Trips?

The main problem with an AFCI that trips frequently is that it’s impossible to know whether it’s merely an annoying inconvenience or if you have actual arc fault circuit breaker issues. To avoid electrical shocks, appliance damage, or a fire, it’s best to use the following steps.

1. Identify the Potential Cause

Taking the time to identify the potential cause can make it much easier to narrow down the culprit. For instance, if it trips whenever you’re running your dishwasher and microwave at the same time, you should have a professional electrician investigate both devices.

2. Make Sure You’re Within the Breaker’s Capacity

Remember: Whenever you overload the breaker’s capacity, it’s going to trip your AFCI.

3. Get Repairs

Once you’ve identified the problem, be sure to get it repaired right away. This could be as simple as tightening a loose connection or as difficult as replacing your wiring.

4. Have an Electrical Inspection

The best way to set your mind at ease is by having a professional electrician inspect your entire electrical system. They’ll be able to determine if your system has any defects or is otherwise unsafe.

Troubleshooting Arc Fault Breakers

If your arc fault breaker keeps tripping, you can try to isolate the problem by doing the following:

  • Check for damaged wires or loose connections.
  • Connect and turn on only one device at a time.
  • Unplug everything from the AFCI, reset it and give it time to settle.
  • Avoid putting excessive strain on the circuit.
