Thanks for the replys. Here is what i am doing. I am putting in a 100amp sub panel and from that will run 240v 20amp breakers and 1 120v 20 amp for my switch, router and fans. My main panel is about 2 feet from the sub and the sub is 1 foot from my miners. I got a triplite 100-240v 20amp pdu along with all the needed c13 adapters. 100 amps should give me more than enough room for now as i will only be using about 25 amps.
