ABSTRACT OF THE DISCLOSURE A portable ground fault circuit interrupting (GFCI) device includes a housing equipped with two sets of back mounted contact blades or prongs for insertion in a con- ventional duplex wall receptacle. One set of contact blades conveys current from on socket of the wall receptacle to a known GFCI receptacle via a relay, both mounted within the housing. The other set of blades are dummy blades frictionally engaged in the other wall receptacle socket to reliably retain the portable GFCI device in place. The GFCI receptacle is accessible through a front opening in the housing for plug connection with circuits for which ground fault protection is afforded.
