How many amps does a 3hp electric motor draw? I'm thinking something like 30-45? Can it be wired to 220?

Hi,

1 HP equals about 746 watts so 3HP is about 2,200 watts. On a 120 volt circuit, that's about 18.5 amps, assuming a 100% conversion of electrical energy to HP. Since motors are about 85% efficient, at 3HP max you'd probably draw about 22 amps. So......IF it's a 120 volt 20 amp circuit, you're marginal in being able to operate it......
