Last year I purchased a Tree 250 CNC mill. I hired an electrician to get it all wired in to my rotary phase converter and the main power. He hooked it up to a 30amp breaker. Do to changing circumstances I was never able to get the machine running at that location and I'm moving it home to run in my home shop. As I'm wiring everything in it seems like I need a 50amp breaker to power the 3hp motor on start up.

Is this correct?
