What is an AFCI device?

AFCI stands for Arc Fault Circuit Interrupter.
What does an AFCI device do? An AFCI device (a circuit breaker or a receptacle) is designed to protect against fires caused by arc faults in electrical wiring.
How does an AFCI breaker work? An AFCI breaker, besides of having the function of a common circuit breaker, continuosly monitors the current flow and distinguishes between normal and unwanted arcing conditions. Once an unwanted arcing condition is detected, the AFCI trips and de-energizes the circuit.
