ABSTRACT:
A ground fault interruptor (GFI) electrical connector receptacle device for use with a twist-lock, multi-prong plug has passages in the face plate in registration with electrical contact blades coupled to a GFI circuit to disconnect the blades upon detection of a ground fault. The configuration and shape of the passages through the face plate accept the twist-lock plug so that the foot of the L-shaped grounding prong of the plug is brought into engagement with the rear surface of the housing face plate when the plug is rotated to restrain the plug from axial removal.
