  • Patent number: 4767359
    Abstract: A six plug safety receptacle is described that is designed to replace the standard double plug receptacle usually found in most homes and businesses. In one embodiment the receptacle is adapted to plug into a standard three prong receptacle. The face plate is usually removed and the receptacle is locked in place using the same opening that secures the face plate. In the second embodiment the outlet contains a terminal block having three terminals adapted to be connected to the house wires located in the receptacle box. In this case the standard double plug receptacle is eliminated and the wall receptacle is secured to the box by the same two screw holes in the box used to secure the former receptacle. A circuit breaker and an external switch control for resetting the circuit breaker is located on the wall receptacle.
