Abstract
An electric receptacle for ordinary household or trade size junction boxes having a complete ground fault circuit interrupter incorporated in the receptacle, including electronic components to detect a ground fault on the load side of such receptacle, and a coil and trip mechanism which is actuated when a ground fault is detected. A number of the components are utilized in this invention in ways that enable them to perform multiple functions eliminating the need for separate components and the space they would require, thereby making it possible to install a complete ground fault circuit interrupter in a smaller space within a receptacle.
