ABSTRACT:
An electrical bussing and jumper assembly for use with electrical switching devices such as circuit breakers in a three-phase distribution system. The bussing and jumper assembly comprises a plurality (three) of relatively thin, wide, bus plates stacked together in a compact sandwich-like array. Each of the plates has a plurality of jumper portions extending transversely through openings or cutouts provided in the bus plates superimposed thereover. The bus plates are insulated from each other by means of insulative coatings (e.g., of polyvinyl chloride) formed on the plates and also by means of sheets of insulative material (e.g., of polyethylene terephthalate) disposed between the coated bus plates and having openings therein aligned with the openings in the bus plates. Switching devices for use in a current distribution system are attached to the jumper portions of the bus plates, using threaded openings provided in the jumper portions.
