How is the surface-mounted electrical box grounded
Connecting the receptacle grounding terminal to the metal box ensures an effective ground-fault current path. Two 20 amp circuits were pulled to the building- so two hots, two neutrals and one ground. The ground wire was terminated on the receptacle. In addition, four installation rules warrant the continuity of the equipment. Find the answer in Sections 250. 146 (A), (B), (C), and (D) of the NEC. It establishes a dedicated, low-resistance return path for stray electrical current, preventing dangerous voltage from building up on conductive surfaces.
