Abstract: The housing includes two outwardly flanged channel members, four auxiliary housing members of generally Z-shaped cross section, and four end plate members. Each flange of the two flanges of one channel member is secured to one of the two flanges of the other channel member by a row of screws which also secures one pair of the Z-shaped auxiliary housing members in place, reversely positioned with respect to each other and with free end portions pointing toward the other pair of Z-shaped auxiliary housing members secured to the other flanges of the channel members. The flanges of the channel members and corresponding portions of the Z-shaped auxiliary housing members are cut away at opposite ends of the housing to present flat surfaces to the end plate members, which are secured in place for additional strength at the joints when sections of the bus duct are secured together by tie channels. Gaskets are provided between the flanges of the channel members and under the end plate members where the flanges are cut away.

Abstract: A two-part hinged cover is inserted between the opposite flanges of the tops of a pair of connected bus duct sections at the joint therebetween and straightened to abut their top surfaces. The cover is locked in the straightened position by a pair of screws. A gasket secured to the cover forms a seal between the top surfaces of the bus duct sections and the cover.
