Buss bar - rivets or bolts?

Buss bar - rivets or bolts?

Buss bar - rivets or bolts?

(OP)
I have a Westinghouse switchgear (460v, 1400A)with copper finger clamps to the buss bar. The suppport base end (opposite from clamping end) of these fingers are attached to a solid copper yoke (feed power connector) by 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 the fingers be bolted? Any problem with metals to the copper; strength; code? Thanks for any help offered.

RE: Buss bar - rivets or bolts?

If you touch any of that stuff you'll void the UL listing.  Get the manufacturer to fix it for you or replace it all together.
