If you have a piece of equipment that is 220 volt single phase,and nameplate of 70 amps, and has a 100 amp breaker installed in the machine,can you hook this up to a 20 amp breaker with # 12 wire,and be legal ? The reason I ask is that is how the machine is wired and it is only used at about 30 second intervals and it stays on,I'm thinking that regardless of if it runs or not you still have to size the breaker and wiring to the machine and not just what works
