FIELD: electricity.
SUBSTANCE: invention is attributed to electrical energy industry, specifically to grounding devices for movable electric installations intended for maintenance personnel protection against electrical shock. Two locking bolts with smooth cylindrical nonthreaded ends are additionally introduced into device at that in the hammer body there is through slot with cylindrical wall concentric to hammer axis and width equal to metal rod diameter. In one of the side faces of hammer there are two through holes with inner thread up to vertical through slot in which holes locking bolts are screwed from the outside to lock rod in the hammer.
EFFECT: elimination presence of loop joint of grounding device elements and design simplification.
