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.
