ABSTRACT:
A ground fault circuit interrupter (GFCI) yoke with integral grounding screw and simple staked ground receptacle stab arrangement provides the device grounding features. The mounting screws that are attached to the yoke by means of staples provide a wall box self-grounding feature. A push-to-test arrangement is provided by a neutral strap and test contact attached to the line receptacle stab through a current limiting resistor. Depressing a test button energizes the test circuit by electrically connecting the test contact with the neutral strap. The combination of the line and neutral receptacle stabs with the line and neutral moveable contact arms and the arrangement of the receptacle stabs in alignment with the receptacle plug-in slots allows the push-to-test and interrupter contacts to be assembled within the GFCI enclosure without additional wiring.
