Abstract
An electrical wiring device, disclosed in the form of a duplex receptacle having the usual cover, body, terminals and mounting strap of the type extending longitudinally of the body rear surface and along the end surfaces. Two pairs of ribs are formed integrally with the body and extend in parallel relation longitudinally of the body rear surface with the strap lying between the two pairs of ribs. The purpose and effect of the ribs is to form a physical barrier of dielectric material and to lengthen the surface distance between the strap and portions of the hot and neutral wires terminated on the sides of the receptacle from which the insulation has been removed, thereby inhibiting electrical contact or arcing between the bare wires and the strap.
