An arc-fault circuit interrupter (AFCI) or arc-fault detection device (AFDD) is a circuit breaker that breaks the circuit when it detects the electric arcs that are a signature of loose connections in home wiring. Loose connections, which can develop over time, can sometimes become hot enough to ignite house fires. An AFCI selectively distinguishes between a harmless arc (incidental to normal o… WebPlease note: Federal Pacific is a separate entity from Federal Pacific Electric Company, a now-defunct entity that sold circuit breakers and panel boxes that today, must often be replaced for a variety of reasons.
