   en.wikipedia.org/wiki/Arc-fault_circuit_interrupter

   This AFCI (the circuit breaker with the yellow label) is an older generation AFCI circuit breaker. The current (as of 2013) devices are referred to as "combination type." An arc-fault circuit interrupter ( AFCI ) or arc-fault detection device ( AFDD ) [ 1 ] is a circuit breaker that breaks the circuit when it detects the electric arcs that are ...
