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.

A busway and insulator assembly for use with the busway are described. The insulator assembly provides access to the conductive busbars through the busway housing and is configured for use with plug-in tabs which extend from the outer edges of the busbars. The insulator assembly includes a base having openings therethrough for cooperation with each plug-in tab. Insulated stabs extend from the insulator base and are disposed between the plug-in tabs-to prevent arcing between the tabs and exposed areas of the busbars. Additionally, the insulator base includes track members for slidably receiving an insulated cover which may be moved into a position blocking access to the plug-in tabs or moved to a position permitting access to the plug-in tabs.

An electrical power distribution busway system which includes a housing having side channels and top and bottom channels is described. The channels enclose and secure at least one stack of conductive busbars in place. At least one of the top or bottom housing channels is adjustably mounted between the side channels so the overall housing may be adjusted to accommodate various arrangements of busbars or busbars having different thicknesses. In a preferred form of the invention, the adjustable channels include holes which are aligned with elongate slots through the side channels. Fasteners extending through the aligned holes and slots allow the adjustable channel to be moved and fixed at different locations along the elongate slot.
