Should be good there. They are at least single phase and might even be DC.

I'm sure its going to be a pretty good heater this winter in my small shop.Running solo should not be too bad. Less than 5A I remember reading somewhere.Of course if I keep adding processor modules and/or an RA92 or two I can see that changing.If I can leave it running I'll add it to my other Hecnet machines(emulated)
