ABSTRACT:
A modular, light-weight, portable electric power distribution cabinet having high structural integrity and being readily adaptable for cost effective use in a wide variety of applications. The cabinet can be arranged to be a main power feed, trunk or branch feed type cabinet and a plurality of cabinets of said type can be selectively coupled to one another to provide a power distribution network of any desired configuration. The cabinet also provides for direct access of power cables to the interior of the cabinet so that cables with lugs at the ends thereof can be directly coupled to a bus feed arrangement within the cabinet. The direct access feature of the cabinet includes a cable clamp door to simultaneously engage and clamp a plurality of lugged cables for ancillary strain relief. The cabinet includes a transparent panel to permit a worker to view the interior of the cabinet without exposure to an electric shock hazard so that the worker can attend to the coupling of the lugged cables to the bus feed arrangement. The transparent panel is provided with small diameter holes for direct insertion of an appropriate tool to engage set screws of the lugs of the lugged cables so that the lugged cables can be fastened to the bus feed arrangement without having to remove any panels from the cabinet.
