ABSTRACT:
A receptacle, such as one for a duplex electrical outlet, includes a grounding plate facilitating ready grounding of the receptacle. A conventional ground screw is provided at one end of the receptacle and the grounding plate abuts the receptacle housing and has an opening therein for receipt of the ground screw, and a contoured surface extending away from the opening and for operatively engaging a ground object. The ground object may comprise a face plate for the receptacle, the grounding plate having a serrated edge abutting the face plate. Alternatively, the ground object can be a ground wire, in which case the grounding plate contoured surface comprises an arm having a V-shaped notch, or a strip with a tongue pressed from it, for receiving the ground wire.
