I have a 60 hp motor located 360 feet from the power source (480v 3ph.) I recomended #2 wire for the run But they ordered the starter panel and it came with a 250 amp thermal magnetic breaker. I asked them to try and swap it out for a 125 A. so the wire would be rated for the breaker but, other electricans are telling them that it's fine to run the smaller gage on the larger breaker. I haven't seen anything in 430 that says you have to size your wire for your ocpd, just to size it from you fla. But I have allways sized wire from the ocpd. Any final word on this?
