I have the basics down and have a 15kVa Hammond step down transformer. Already running a 15hp RPC. Brought line voltage in and checked the outputs and have 208-210 on the output. The one thing I'm unclear on is the wiring needed for ground. There's a ground lug inside of the case. I'm assuming I need to run ground from the RPC side to that and ground from the CNC side to that. But I've also read about the X0 terminal being connected to that as well. I'm hoping someone can better explain that portion of it to me.
This is residential service. 200A main to a 100A sub in the garage. 70A breaker feeds the RPC. The transformer will only be in between the Brother and the RPC.
