I am in the process of designing a grounding assembly for a high voltage switch and need to determine what contacts will handle 1200amps. The contacts are U-shaped and a flat copper conductor bar rotates into the U-shaped contact to make the connection. Can anyone point me to a reference or give me info on sizing the contacts? To decrease the amount of heat at the connection do I need more surface area?

You might send a PM to m.s.j -- he seems to be pretty experienced in high-power stuff like that:
