Abstract

A device electrically interconnects a high voltage cable to a bushing of a deadfront electrical apparatus or switchgear. The device comprises a feed-through bushing and a separate U-member. The U-member can be installed onto, or removed from, the bushings without having to disconnect the ground. A driver mechanism applies a force to the U-member at a location substantially midway between two parallel legs of the U-member for installing or removing the U-member without cocking of the legs. The U-member carries female contacts which are engageable with male contacts of the bushings.
