I have an X-ray machine that has 80amp fla. It also requires the the ground to be sized the same as the hot wires. Requires 3 hot wires and no netrual. 3 phase 480v.
I'm providing a 100A breaker with 3#2 and 1#2 green ground. All copper.
My question is does the X-ray require a redundant ground cable? And if so, what size?
Thank you
