ABSTRACT:
An improved housing for a busway system is provided by a two-piece ground bus which includes a generally U-shaped upper section having a top portion and a pair of parallel side flanges extending a predetermined distance and a generally U-shaped lower section having a bottom portion and a pair of parallel side flanges extending intermediate and parallel to the side flanges of the upper section. The main bus bars are retained intermediate the top portion and the bottom portion of the ground bus while also being positioned between the side flanges of the upper section of the ground bus. A side rail is provided on each side of the ground bus. A plurality of fasteners extend along the length of the busway section and connect each side rail with both the upper and lower sections of the ground bus. Ears formed out of the side rail members immediately adjacent the top portion of the ground bus provide additional reinforcement of the housing for resisting magnetic forces created by high fault currents running through the bus bars.
