Provides both arc fault protection per UL1699A and ground fault protection per UL943 in one convenient device Protects from both series and parallel arcs downstream from the Outlet Branch Circuit (OBC) AF/GF receptacle OBC AF/GF receptacles also protect from upstream series arcs Trip indicators make it easy to diagnose arc and ground faults Device self-tests periodically to ensure proper function of both the ground fault and arc fault protection elements Automatic grounding system eliminates the need for bonding jumper in grounded metal enclosure; provides redundant measure of ground continuity when jumper is used Lock-out functionality prevents miswired line-load connections and GFCI/AFCI circuitry damage
