The National Electrical Manufacturers Association (NEMA) has published ABP 2-2011 Recommendations on AFCI / Home Electrical Product Compatibility, developed by NEMA’s Molded Case Circuit Breakers Product Group. According to NEMA, the guide provides designers of home electrical products (HEPs) with information on the operating parameters of arc-fault circuit interrupters (AFCIs), with the goal of avoiding conditions in which the HEP could cause the unwanted tripping of an AFCI. ABP 2 offers guidance for designing HEPs operating at 120 Vac and rated at 20 amps or less, and characteristics discussed in the guide include ground-fault current, peak currents, and high frequency emissions.
