ABSTRACT:
A high-voltage cable is fixed to the single leg of a 600-amp "T" connector, which in turn is coupled for non-removable engagement with an insulating bushing fixed to a wall of the apparatus housing it is to serve. A removable screw-applied link member selectively couples the remaining leg to the apparatus bushing whereby power is supplied to the apparatus only when the link is present and isolates the cable when it is absent. A bushing extender and novel contact extenders fix the positions of components and serve to align the two arms of the link. Each of the arms includes an externally threaded stud for engagement with the contact extenders which are positioned in the "T" leg and bushing extender such as to engage the studs before interface interference to assist and guide the screw assembly of such parts. By this system, the apparatus and cable can be tested, grounded and a visible break performed without moving the high-voltage cable.
