ABSTRACT:
An electrical receptacle of the three contact type, one of which receives the standard, normally non-current-carrying, system ground pin of a corresponding cap.
A set screw is advanced into a threaded bore in the plastic body material of the receptacle to make contact with the aforementioned ground pin. The bore may be from the receptacle front or from behind the face plate, in either case preventing the casual or surreptitious removal of the cap and cord and the associated equipment.
