Combination Arc Fault Circuit Interrupter (AFCI) is designed to eliminate arc faults, which are unintended electrical arcs that may ignite combustible materials in a dwelling. The AFCI features a compact design, is easy to install, and offers flexibility to address shared and mixed neutrals. It meets the latest National Electrical Code (NEC) requirements. The AFCI prevents arc faults caused by damaged wires, neutral leads pinched to a grounded metal box, worn electrical insulation, loose electrical connections, shorted wires, wires or cords in contact with vibrating metal, overheated or stressed electrical cords and wires, or misapplied/damaged appliances. The device enhances safety by preventing personal injuries, electrical shocks, and fires.
