An arc fault is an unintended arc created by current flowing through an unplanned path. Arcing creates excessive heat that can easily ignite surrounding material, such as wood framing or insulation, resulting in a hazardous fire.
The 2014 National Electrical Code® allows for Outlet Branch Circuit (OBC) AFCI receptacles to be installed under various conditions to provide arc fault protection.
Arc Fault technology saves lives and has been an industry standard in new construction for over 15 years. Today’s arc fault technology has been proven through arc fault breakers and has gone through several iterations to reduce unwanted tripping due to interference from devices or appliances. Arc fault circuit interrupters have been established as a stable technology which can be used in conjunction with various loads through the home in both AFCI breakers and AFCI receptacles.
