Patent ID: 8558112

Claim:
A high amperage electric cable bus system comprising: a longitudinally extending raceway comprising, a plurality of longitudinally extending cable trays, each cable tray having a generally modular construction and including a pair of generally parallel longitudinally extending side members, and a plurality of laterally extending cross supports, the cross supports spanning between and fixedly coupled to each said side beam, the cable trays being positioned in a generally stacked orientation with the side beams of an a first said cable tray being secured in substantially aligned juxtaposition with the side members of a next lower cable tray, a plurality of electrical cable arrays selected for the distribution of high amperature polyphase electrical current disposed in an interior of said raceway, each cable array being associated with a respective one of said cable trays and comprising a plurality of generally parallel spaced electrical cables disposed in supporting contact with the cross supports of the associated said cable tray, clamping members for securing said electrical cables of each cable array against movement relative to said associated cable tray, and further including at least one elastomeric grommet at least partially engagable by one said electrical cable and interposed between selected one of said cross supports and an associated one of said clamping members, each said grommet including a pair of flanges provided for bearing contact with part of said selected cross support and associated clamping member respectively.
