An electrical receptacle directly mounts on a conventional service panel to adapt the panel for electrical connection with a standard power cord. The receptacle has an insulative housing and includes one or more lower spring contacts, two or more upper spring contacts and a rear contact. One or more lip members on the rear end of the housing are inserted beneath the panel's hook-like retaining tabs, and each lower spring contact is thereafter pivoted into wiping engagement with one of the blades on the panel that serve as power terminals. The respective prongs of the power cord are inserted through openings on the upper face of the receptacle for wiping engagement with the upper spring contacts. At least one of the prongs is thus connected electrically to a corresponding blade on the panel via an interconnected upper spring contact and lower spring contact or, alternatively, via an interconnected upper spring contact and rear contact, which rear contact is tied to the load end of a selected circuit breaker module by an interconnecting cable. In one preferred construction, a connection path that reverses back upon itself and that includes an overload protection device interconnects each rear contact with an upper spring contact. At least one other prong is connected electrically to a ground bus on the panel via an interconnected upper spring contact and rear contact, which rear contact is tied to the bus by a cable.
