US Patent 8106297 Grounded conduit bushing

By providing a grounding conductor assembly affixed to a conduit bushing in a manner which enables the grounding conductor assembly to extend inwardly from the bushing, effectively being positioned coaxially with the inside diameter of the rigid metal conduit, conduit bushing is realized which enables all grounding wires to be quickly and easily mounted to the grounding conductor assembly. The conduit bushing of the present invention includes a generally circular shaped cover or cap member mounted to the terminating end of the conduit and incorporating an enlarged aperture which overlies the elongated passageway formed in the conduit. In this way, the electrical power carrying wires are able to extend outwardly from the rigid metal conduit into the desired outlet box, junction box with the grounding wire being quickly affixed to the receiving zone of the grounding connector assembly.
