An electrical receptacle assembly with an enhanced heat dissipation arrangement includes a housing having a front side with plug contact receiving openings and a rear side spaced from the front side, a circuitboard mounted in the housing between the front and rear sides thereof and spaced from the rear side, a plurality of varistors mounted to the circuitboard and disposed between the circuitboard and the rear side of the housing, and a mounting bridge fitted over the exteriors of the rear side and top and bottom ends of the housing for mounting the housing to an outlet box and providing a heat sink for dissipating from the housing heat generated by the varistors. The varistors are mounted to the circuitboard in the housing on the front side thereof opposite to the rear side where the electrical components are mounted to the circuitboard. The varistors have leads which are bent into G-shaped configurations so that portions of the leads extend from the front side to the rear side of the circuitboard around the peripheral edge thereof so as to place the varistors along the rear side of the circuitboard adjacent to the interior rear side of the housing in close proximity to the mounting bridge for rapid heat dissipation and remote from electrical components mounted on the front side of the circuitboard. A heat barrier plate made of heat-retardant material is positioned between the varistors and rear side of the circuitboard to impede heat produced by the varistors from reaching and impinging upon the circuitboard. The leads of the varistors also extend around the periphery of the barrier plate.
