ABSTRACT:
Sections of a bus bar stack are coupled together with insulating spacers between bars of different potentials, by a clamping device that embraces the stack, thereby avoiding the need for cutouts in the bars at the coupled junction. The form of the clamping device may be a U-shaped bracket encompassing the stack and having adjustable clamping means mounted on the leg ends for applying resilient clamping pressure on the stack through a pressure member bridging between the bracket legs. Alternatively, a support on one side of the stack and a clamping element spaced from the support are joined by levers. Adjustable clamping means on the ends of the clamping element apply clamping pressure on the stack through the levers. The support may form part of an enclosure for the bus bars and may include an insulated tray having offset slots for supporting the coupled bus bar sections in desired relation to each other.
