Abstract
An electrical wiring box assembly includes a non-metallic electrical box, a metallic grounding plate and a conducting clip. The electrical box includes a pair of mounting lugs for releasably fastening a wiring device. The grounding plate includes a central portion having a downwardly extending coupling flange frictionally retained in a slot formed in one of the box mounting lugs. The grounding plate further includes a pair of connecting portions extending downwardly from the central portion, each having an extending outwardly leg. The conducting clip includes a flat body portion and a raised portion. The flat body portion has a slot for receiving the coupling flange of the grounding plate and a self tapping hole for receiving a mounting screw. The raised portion includes a hole and a plurality of tabs formed by radially extending slits. The hole is slightly smaller than the diameter of the mounting screw. Upon passage of the mounting screw through the hole with the slits, the tabs are deflected downwardly, making firm electrical contact with the mounting screw.
