Busway joint

摘要

An electrical power distribution busway joint is shown and described. The joint is configurable to electrically couple the phase busbars, the neutral busbar(s) and the ground busbars of adjacent busway sections. Each of the phase and neutral busbars from adjacent busway sections are in electrical contact with the inside surfaces of a pair of rectangular connector plates. The connector plates are fabricated from a conductive material to include at least one opening and a spacing tab fabricated from at least a portion of the material removed from the plate to form the hole. The spacing tabs of the plates cooperate to maintain a space between the plates which facilitates insertion of a busbar into the space. The tabs also prevent over-insertion of busbars into the joints which may damage insulating material within the joint. The outside surfaces of the connector plates are each engaged by a rectangular insulator formed from a section of pultruded insulating material. The cross-section of the insulator is configured to provide an increased surface distance where connector plates are located on each side of the insulator. The joint may also include end caps, where one or two bolts are fasten the end caps, insulators and connector plates together such that the busbars are clamped between respective connector plates.
