ABSTRACT:
An electric receptacle for trade size outlet boxes having a ground fault circuit interrupting mechanism incorporated therein. A receptacle housing includes contact jaws seated therein to receive the plug of a conductor leading to a load, electronic components to detect a ground fault and grounded neutral condition on the load side of the receptacle, plus a coil and trip mechanism to open the receptacle circuit on occurrence of a ground fault or grounded neutral condition. The complete receptacle assembly is approximately the same depth as conventional household receptacles which do not have ground fault circuit interrupting means included therein. Means to periodically test the ground fault interrupting mechanism is also included in the receptacle assembly, as well as means to indicate the circuit has been interrupted and means to reset.
