Determining
the Cause of AFCI Tripping
Document Number: 0760DB0204
When an AFCI trips, the cause of the trip must be determined before placing the circuit back into service. This data bulletin outlines several of the most common causes of AFCI tripping however it does not cover all possible causes that can occur. Arc Fault Circuit Interrupters (AFCIs) are required for installation in residences under the 2002 National Electrical Code (NEC). The 2005 NEC requires AFCIs to transition from the present (branch/feeder) AFCIs to combination AFCIs. The QO and Homeline Combination Arc-fault Circuit Interrupters, also referred to as CAFCIs, were developed to meet the NEC 2005 requirements effective January 1, 2008.
