![]() If i had it to do over again, i'd focus more on 220v tools whenever possible. because of their lower amperage draws, the 220v tools leave more amperage for the 110v tools. i have both 110 and 220v tools adn only a 30A sub panel. some 20v motors come up to their operating speed faster than if they were operating on 110v and, because 220v draws lower amperage, it leaves more of a panel's capacity available for other loads. both the neutral and ground both terminate at the same point in the panel, and both ultimately go to ground.Īlmost all motors on tools we hobbyists use develop the same hp in either 110 or 220v configurations. ![]() i would be somewhat surprised to find the emt on your 220v lines is actually functioning as a ground, although it might. re: the emt comment, while it can function as a ground, if pure 220v is supplied to an outlet, it is usually done with 2 hots and a ground. the neutral would be needed if the 220v load needed 120v for any control applications. a 220 line that will not be supplying 120v needs only 2 hots and a ground. If not, don't.Click to expand.i believe that is incorrect. If you got 220vac in the shop, put a 220vac plug on the cord and use it that way. I would not think of doing this unless I was inclined to use my PowerPro today as a 220vac device and tomorrow as a 110vac device and the next day as a 220vac device, etc, etc. Yes, it works great as long as no one makes a mistake or uses it wrong. For comparison, if we were using 220V voltage, the max. Therefore a 110V outlet on 15A can provide 2,640 watts of power. It is a safety hazard and a code violation. Therefore a 110V outlet on 15A can provide 1,760 watts of power. ![]() There is a reason why Shopsmith will not sell you an adapter that does what is being discussed here. If nothing other than the PowerPro ever, ever gets plugged into that receptacle there is no harm done.īut if something other than the PowerPro, something like an electric drill or soldering iron, gets plugged in there - it will be toast. 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.
