  • Patent number: 7248056
    Abstract: A three phase receptacle tester including a housing, an electrical connection and a coupling assembly. The housing includes an outer surface, an opening and an inner cavity, wherein the opening provides access to the inner cavity. The electrical connection assembly having a body, condition indicators and a coupling assembly. The body having an outward surface, an inward surface and a periphery. The periphery of the body matingly engaging the opening of the housing, so as to preclude access to the inner cavity. One prong extends from the outward surface of the body for each phase and one prong extends from the outward surface of the body corresponding to a ground/common. Each of the prongs spaced radially outward from a central axis. Each of the phase prongs electrically connected with the ground/common prong and the condition indicator positioned therebetween. The condition indicator identifies at least one of current flow between a respective phase prong and the ground/common prong.
