Hey,
i am doing a similar setup as yours. Were you successful with the transformer?
[snip]
try and find a 50amp single pole circuit breaker.
and it needs more than 10 gauge wire it needs 8 gauge and there would be a proper plug to carry that much current.
If OP and others are going to be serious about their mining set on the scale of what @philipma1957 does then better follow their threads. I have been a secret follower of their threads and seen all the types of experiences that they have shared. Whether it is setting up a new miner, bringing in a new mining rack that can hold a big set up, or may be cooling down the entire mining farm, they have always seen putting their actual pictures and explaining what is happening at their facility.
I think that is the best way to go with it. You also share your experience and we can visualize the entire project with pictures. Please start checking out what they have done in the past. Moreover, there are detailed set up threads for dummies where one can get every bit of knowledge on how to proceed.
