IMO that is not a 230 volt compressor. If I read it right you said it had 2/14ga wires coming from it. That usually means 120vt @ 15 amps. Check out the plate on the motor and see what it says for volts and amps. If not too sure call an electrician. If you hook it up to the dryer outlet you could get some serious smokin' happenin'. With a 40 amp breaker its gonna do some damage before it blows. Good Luck and be safe. Afros are out!!!
