Abstract
A grounding device for an electrical conduit which includes: a bushing having an outer wall and a notch in the outer wall; a lug rotatably accommodated by the notch; and a grounding connector with a set screw which is attached to the lug. The grounding conductor is electrically contacted to the bushing by the set screw. In addition, the force exerted by the set screw frictionally engages the lug with the bushing and locks the lug in place so that the lug is no longer free to rotate. The grounding connector can be reoriented by loosening the set screw and rotating the lug to a different orientation.
