Abstract

Abstract A power transfer device having various electrical components adapted for interconnection with the electrical system of a building includes a cabinet having a face plate provided with a socket opening which normally accommodates a power input receptacle adapted to receive a plug connector electrically connected to a generator. The power transfer device includes an internal compartment defined by the cabinet, and a set of connections corresponding to the electrical components located within the internal compartment. A cover plate terminal assembly is removably connected to the face plate for covering the socket opening to prevent access to the internal compartment and for providing a direct, permanently wired power input arrangement rather than a plug-type power input via a power input receptacle. The cover plate terminal assembly is also electrically interconnected with the electrical component connections in the internal compartment.
