ABSTRACT:
A ground adapter is disclosed which comprises an electrically conductive metal body having a threaded cylindrical end portion of a size fitting a threaded opening in the wall of an object to be grounded. The metal body has a transversely extending hole at the end portion opposite the threaded end. A small longitudinally extending threaded hole is provided in the end wall of the metal body and intersects the transverse hole for the ground wire. A screw member is positioned in the threaded hole and movable into and out of the transverse hole for anchoring a ground wire in place. In a second embodiment, the transverse hole may be threaded and the longitudinal hole made smooth to receive an a ground wire extending therein. Other embodiments include auxiliary connections for securing a metal bonding ribbon in place as well as a grounding wire. One such embodiment clamps a metal bonding ribbon around a pipe or conduit for grounding. Another such embodiment clamps a metal bonding ribbon and a grounding wire together in the ground adapter.
