Isolated ground receptacle

摘要

A strap for mounting an electrical wiring device in a mounting box comprises a yoke member having laterally projecting tabs on each end thereof, the tabs being fastened to the mounting box. A pad of electrically insulating material is positioned upon the tab so as to be interposed between the tab and the mounting box when the strap is mounted. The tab and pad are each provided with a slot through which a mounting screw passes, and the portion of the pad defining the slot has a beveled aperture with resilient lips so as to engage the threads of the mounting screw received in the slot to prevent movement of the mounting screw with respect to the strap and to insulate the strap from the mounting box.
