The concern here is that with the adapter that is being proposed plugged into a 220vac outlet, there is a standard 110vac receptacle that is hot with 220vac. The PowerPro will operate safely when plugged into either 110vac or 220vac. I am no electrician but I am pretty sure you will burn up your motor and/or wiring.

If that plug matches the receptacle installed by your electrician, he should have installed a 20A 230v branch connected to a 2 pole 20A breaker. That concern is greatly reduced than if it was being used at 115v and the original induction motor. The only concern I would have is the length and wire size of the modified extension cord. ![]() I like the short, secured to the pp plug adapter cord that could prevent that as described by Paul(?) in another thread. into the '115v' end and the plug end into 230v and the 115v tool is potentially damaged as described in the 'nay' response. One caveat! You must realize the possibility of someone not realizing the unique 'function' of the modified extension cord could plug a 115v tool. the motor does not run on 'AC' and is not directly connected to the power source(115/230). I am sure the power supply is a 'switching' type that is designed to run on 230V, but will supply the dc output at a reduced power capacity at 115v. ![]() The design includes a voltage sensing(more likely a voltage tolerance?)power supply and the controller applies dc pulses to the motor. Tis unusual for motors of this size(hp), but the PP truely will run on either voltage.
