What is a push button circuit breaker called?
eHow may earn compensation through affiliate links in this story. A circuit breaker with a push button to test it is more formally known as an arc fault circuit breaker or arc fault circuit interrupter (AFCI).
What does the red button on a circuit breaker mean?
Breakers with a small colored button marked “TEST”—it could be white, yellow, green, or red—have a dual protective function. And older GFCI breaker from the 1980s with a red test button is shown below. There are two primary types: GFCI (Ground Fault Circuit Interrupter) and AFCI (Arc Fault Circuit Interrupter).
How do I know if my circuit breaker is bad?
If your circuit breaker panel has a foul odor or burning smell, consider checking or testing your circuit one by one. There may be a faulty circuit breaker in your system that needs to be replaced.

How to reset a GFCI breaker?
To reset, you push the breaker switch all the way to “OFF” and and then back to “ON.”. If nothing happens when the test button is pushed, that means the device is not functional and therefore not protecting the circuit in the way it was designed. The GFCI-breakers protect against ground faults, which is essentially current ...
What is GFCI breaker?
The GFCI-breakers protect against ground faults, which is essentially current that is traveling off the intended circuit and may be shocking you. These breakers protect circuits for pools and spa tubs, along with receptacles in wet areas like bathrooms, kitchens, garages, and exterior.
Why do we need AFCI breakers?
Because arcing of wiring is known to be a leading cause of house fires, AFCI breakers have been required for bedroom circuits since early in this century, and more recently they are must be installed to protect virtually all the 120-volt receptacles in a home.
What is a test button on a circuit breaker?
A circuit breaker with a test button. A non-contact voltage meter for testing your circuit breaker if it continues to trip. But to give you more information, there are two types of circuit breakers with a test button. These are:
How to reset a circuit breaker?
Step 1: Locate the Circuit Breaker. Go to your breaker box, open it and locate the circuit breaker that you need to reset. To find that circuit breaker, look for the tripped one or the one which is turned off. Ensure that all appliances, devices, and lights in the circuit are turned off or unplugged; it may trip again if your device has too much ...
What is an arc fault circuit interrupter?
The Arc-Fault Circuit Interrupter (AFCI) or the Arc-Fault Detection Device (AFDD): It is a breaker that detects and trips when there are loose connections or hot wire due to overvoltage. It can also catch and stop dangerous arcs.
What happens if a circuit breaker doesn't trip?
This will cause the circuit breaker to turn off. If the breaker doesn’t trip, it isn’t working correctly, so you need to replace it. Otherwise, you can repeat the process of resetting the breaker to turn it on.

How to diagnose a ground fault?
How do you diagnose a ground fault? Touch the multimeter's black lead to a grounded metal surface and touch the red lead to each wire of the circuit. A meter reading of infinity, O.L., Open Loop, or a needle that stays all the way to the left of the scale indicates an open circuit with no path to ground.
What happens when you press the test button on an AFCI?
When you press the test button on the AFCI, it sends the same signal to the circuit board to make sure that it's still functional. Of course, the AFCI still operates like a normal circuit breaker in that if the dip or surge in current exceeds a five ampere threshold, the breaker is thrown as well. Advertisement.
What is an AFCI breaker?
A circuit breaker with a push button to test it is more formally known as an arc fault circuit breaker or arc fault circuit interrupter (AFCI).
