초록 ▼

An electrical plug and receptacle having safety features is provided. The plug includes a body, at least two conductors, and a skirt. The conductors extend from the body and are laterally surrounded by the skirt. The skirt is retractable into the body so that when the plug is used with a conventional receptacle, the skirt retracts into the body as the conductors are inserted the sockets of the receptacle, shielding a user from inadvertently touching the conductors. The plug further includes a toggle stop that locks the skirt into its fully extended position for using the plug with a safety electrical outlet assembly of the present invention. The safety outlet assembly includes a cover and a receptacle adapted to be secured to an electrical junction box. The receptacle has a receiver adapted to matingly engage the skirt on the safety plug. The cover is removably secured to the receptacle and includes an aperture having a periphery spaced-apart from the outer periphery of the receiver to define an opening for receiving a skirt of a safety plug.
