Most cost effective is 6-15r or 6-20r non locking (no l). These are 240v. From there run a y splitter cable. 30 amp 10 AWG.
Thanks Big Al, the only reason i was thinking 30 amp is so that i can possible increase the amount of miners in there in the future. But i like the t splitter cable idea, i will see how much difference the electrician will charge. He also wants me to work on his computer so my cost may not be so bad.
Can you help me understand what the benefits are of using a 30 amp circuit with a PDU compared to your set up? i have found some super cheap 240v PDUs on ebay.
Also when i dig the trench im going to throw the internet in there too, is it recommended to use the gel filled Ethernet cable or can you use regular Ethernet cable in conduit
I would go with Gel filled, That way its essentially water proof!
