Please provide documentation that our switchgear doors are adequately grounded without bonding jumpers.

Per Mike Orosz on 12/03/08 - ``The ANSI C37 standard does not require bonding wire between door, removable panels etc. to the frame if it is tested and proven that the grounding is adequate. Square D switchgear was tested without the bonding wires up to 50kA SCI level. The frame, doors and panels were OK, the grounding was good. Square D considers the hinges as the grounding path.``
