Question for US miners, I have a unused 20 Amp double pole breaker in my panel. I know it will provide 220V. Any issues hooking up my miners to a circuit with 2 hots and a ground?

You need to check how is the breaker connected. are both poles hot or 1 is hot with the other to neutral? Normally it should be 1 hot and 1 N and both switches are connected externally. if your hot input is 110v, than you have 110v output too, plus N of course.

this is viable as the inside of the breaker box can be such that one of the 2 hot bars may be shorter then the other.

let me see if I can find a photo

best I can find.

please be very careful 220/240 = strong powerful possible death

The circuit is all ready wired to an outlet in the garage, for a 220V welder. I was planning on wiring a new outlet in the house. I understand that a 220 2 pole breaker uses 2 hots and the ground. I guess what I'm asking is it OK to use that kind of circuit on the power supples for miners? I know they will run on 220V.
