Abstract
An electric power busway system comprises a bus bar support housing with the opposite side plates of the housing shaped with troughs to hold the bus bars in their relative positions, preventing the bus bars from moving towards or away from one another and providing the necessary short-circuit protection and bending resistance. The metal side plates are preferably fastened together without the use of fasteners or the need for welding, through the use of a punch and die tool set. A protective insulating sheet is sandwiched between the insulated bus bars and the housing to protect the bus bar insulation coating from ruptures or tears. Clamping blocks are provided outside the protective busway housing to apply friction on the bus bars within, keeping them from sliding out of the housing assembly. The integral busway housing and clamping serve as a ground conduction facility, with the clamping blocks providing a mechanism to connect the busway section to an adjoining section.
