I'm wanting to know the wattage of this motor. My problem is with how the amps is written on the nameplate. My understanding has been that the stated amps should be multiplied by the SF (service factor), and to then multiply that number by the voltage to arrive at the wattage. But this motor says "AMPS SF" 10. Have they already done the math, meaning it pulls 10 amps if the service factor is 1.5?
