I am mining here in the UK I have 4 x small farms, running just under 10PH total now.

I don't use PDU's. I have 1 x 20A breaker for EACH miner, with 2 x iec C14 power cables wired directly into each breaker.

I use these extension cables and cut off the male end:

Happy to answer any questions if you PM me. I would say at £0.10 kw/h you'll struggle to profit though :/
