ABSTRACT:
A bus bar, for electrical switchboards comprises an elongated extruded imperforate metal bar of rectangular cross section having slots, with parallel side walls, extending the entire length thereof. Some of the slots are of T-shape cross section, each with the T-leg portion opening through a face of the bar. Others of the slots are rectangular grooves of generally uniform width, with smaller V-shaped grooves on opposite sides to accommodate threaded end portions of bolts or screws, and each opens through a face of the bar. T-bolts are arranged with their heads in, and slidable along, the full length of selected ones of said T-slots, respectively, to any desired position. The bolts have threaded stems, each of which extends from its associated head through the leg portion of the T-slot in which its head is disposed, and beyond that face of the bar through which the associated T-slot opens. Each stem is adapted to threadably receive a nut for clamping supporting or connecting brackets to the bar. Mounting bolts are threadedly receivable between the grooved side walls of the "threaded" slots. The bus bars can be mounted on insulating channel members by means of the "threaded" slots and mounting bolts and can be connected to each other with their faces coplanar or in intersecting planes by the T-bolts and companion brackets. The bars can be assembled readily in a switchboard.
