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 three relatively-thin, wide bus plates stacked together in a compact sandwich-like array. Each of the plates has a plurality of openings therein defining a pair of parallel side portions and a plurality of jumper portions transverse to and bridging the side portions. The jumper portions of bus plates are variously concave (top bus plate), flat (center bus plate) and convex (bottom bus plate) and spaced from each other such that when the bus plates are stacked together, the jumper portions are arranged in a ladder-like array and central portions of the jumper portions are all in a common plane. 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. A comb of insulative material (e.g., of polypropylene) having portions extending through the openings in the bus plates and i…
