Hi, I have a question for you Moparts electrical and HVAC gurus out there. I had an HVac service tech today tell me that he wants to replace the motor in a rooftop HV AC unit because it is not drawing enough amps. Is a 1.5 horsepower, 3-phase, 208 volt motor running the fan. He says it measured two amps on one leg and the rated amperage of the motor is 6 amps. So I'm wondering if the motor is larger than the fan requires, would it draw less amps? Also when measuring amperage of 3-phase, do you add the amps measured at each leg together to get the total nameplate amperage? Thanks, Joel
