We have in our factory a trim press machine with a nameplate FLA of 192 amps at 460 v 3 phase. No resistive load, just a control plc and 2 servo motors. Avg draw using a clamp on meter is 10 to 15 amps. It is fed from a 30 amp breaker with #10 wire and we have not had any problems for the 8 years this machine has been running, 3 shifts , five days a week. I need to relocate this machine within our factory. I’m stumped at finding a code allowace for under sizing a load, even though experience shows 30amps is more than enough. I hate to install a 200 amp service unnecessarily,but i dont want to be violating any codes at the same time. Any help would be greatly appreciated.
