I have a Westinghouse switchgear (460v, 1400A)with copper finger clamps to the buss bar. The suppport base end (opposite from clamoing end) of these fingers are attached to a solid copper yoke (feed power connector) with metal (magnetic) rivets. The fingers annealed from overheating and no longer clamp tight. Rivets are not coming out easy, and reinstalling rivets will be very difficult without specialty equipment. Can they be bolted? Any problem with metals to the copper; strength; code? Thanks for any help offered.
