Abstract
An all stainless steel grounding electrode uses a coating of stainless steel for an upper collar which has a dual purpose cable connector. The cable connector can accommodate a cable lug and bolt connection or a cad weld connection. A cap for the collar has a one quarter turn dual heavy duty thread set to prevent corrosion from locking up the cap. An osmotic material is placed and replaced in the grounding electrode via the cap.
