Eaton’s Cutler-Hammer Arc Fault circuit breakers (AFCI) provide protection from fires caused by arcing faults. Arcing faults can occur when insulation around cords, wires, or cables is damaged or deteriorated. More than 1/3 of electrical fires that occur each year can be attributed to these arcing faults. AFCI’s are required on bedroom circuits for new construction per the 2002 National Electric Code. AFCI breakers come in 15 and 20 AMP for both our BR and CH Types.
