A bar connector is provided whereby, when the connector is in a locked position on a transformer bushing, a set screw is provided having a conical tapered end. An internally threaded bore hole is selectively provided in the connector at a point such that, when the connector is secured on the transformer bushing, the tapered conical end of the set screw bears against the chamfer of the threaded stud of the transformer, thereby locking the connector in place without damaging the threads of the stud. By utilizing this method for locking the transformer stud, thus eliminating the present lock nut, a completely insulated and sealed transformer bus is gained. An insulating cover positioned at the threaded end of the bar connector provides a flexible cylindrical base which, under thread pressure, seals the juncture of the transformer bushing with the insulated end of the bar connector. After threading the bar connector over the transformer stud, the stud is locked in place, as previously described. A second, larger insulating cover is force fitted over the smaller cover to provide a completely insulated assembly.
