Would someone with a PowerPro that was wired by Shopsmith to run on 220 vac, please post a picture of the power connector on the PowerPro cable.

If the PowerPro was purchased to run on 220 vac, what sort of connector is required for the power source in the shop. I would assume it has two hots (two reds or a black and a red ), an ac return (white) and a ground (green).

That would be incorrect. It is three wires. Shopsmith recommends a standard 15A 250 V plug like this one. and provides instructions with the PowerPro on how to wire the plug. I used a 20A twist lock like this since that is what I have in my Shop

Wonder if ul or csa approved?

Extra degree of 'complexity' over simple cheater cord.

Not really a cheater cord in the conventional sense. My cheater cord has a 220 male and a 110 female. If it ever got disconnected from the Shopsmith's 110 cord and someone plugged in a 110 device into the exposed 100 female connected there could be an issue.

The have created a nonstandard ale plug which plugs into two different nonstandard female plug, it is a lot harder to make a mistake.

Maybe, if someone has it, a simple diagram that shows what is involved in the way of an adapter would help.

How to power a 120 vac load with a 220 vac source.

You have two options:

Replace the power cord with one that has a 220 male connector, legal but limits you to only plugging the unit into 220.
NOT SAFE and possibly not legal: make an extension cord with a 110 female outlet on one end and a 220 male plug on the other. This is what I did, this allows me to use the PowerPro in my shop with 220 or on my driveway at 110.

For my laptop I have a collection of 5 different mechanical adapters they have a US 115 volt female connector on one side and a variety of male plugs that fit 220 volt sockets all over the world unfortunately US 220 is not one of them. I asked about installing a European 220 socket in my garage but my electrician said that was not legal because they use 50 HZ and we use 60HZ to if someone plugged in a European device it might not work or be safe.

You don't purchase a 200 Volt PowerPro that all run on 110 or 220 just like your laptop or cell phone.

It is wire the same as a US 110 device one hot, one return and one ground.

The powerpro does not come in different versions. Only one version but it will run on either 115v or 230v with greater power output at the higher voltage.

I question the existence of a nickel plated terminal on any 230v plug
(usa).

Realize there are different receptacles for 230v 15A and 20A - the plug needs to match.

The 230v plug in the ss instructions is a 15A version.

The 230v plug in the miller video is a 20A version, and the 115v plug is a 15A version.

The 230v receptacles mentioned above both have two 'hots' and and a ground. No neutral is needed/used.
