Abstract
A grounding jack, particularly useful in a patient load center of hospitals, and the like, is disclosed, wherein the male and female members thereof, when assembled, may be locked together by the non-current-carrying or insulated portions thereof, and the frictional engagement between the surfaces of the current-carrying portions is such that breakage of the locking means or inadvertent unlocking between the two members will not impair current flow.
