Alright, lets try a test.
So in theory the field coil is rated for 220v, not 120 (or 115, or 110 or whatever) and it's wound for 50hz power. My prediction is that it will be a slowdown of 0.55:1/10 KwH which would be almost useless.
No I was wrong. I lined up the 1/10 dial to .3, applied a load and it was only off by about 0.01KwH by the time it landed on .4 KwH.
This is fine. It's not going to be spot-on accurate but that's close enough to let you have fun with it.
