Is there any negative to increase the breaker to 50amp( 50 x .80 = 40/7 = 5.6a) for 5 miners and one PDU per breaker? I wonder if they have a 5 (c13) PDU at great price?

Also, Big Al says here ( https://bitcointalk.org/index.php?topic=2478836.0 ) that for every 11amps of three phase power you can run three miners one for each phase? If true then, 50a x .80 = 40a/11a = 3.63a x 3 miners = 10.9 miners?

50 amps breakers require 8 gauge wire. Good luck finding matching receptacles unless your using a PDU that matches that.

Your original post indicated 208V power, which is what I presumed was being supplied to your stated 2 pole breakers, with the 3 phase power balanced between them. For anything more complicated, hire a certified electrician and have him do the math. 3-phase power is not as simple to work with as single phase.

Correct I was looking for PDU's to match and found 3 phase PDU's here http://www.bitcoinpowerstrips.com it is the marketing page for http://www.raptorpowersystems.com/

I wanted to go from the panel, hard wired directly to the PDU mounted on the shelving. We ordered a WYE/3phase transformer and we have electricians, I just do not like them as much. They are not very helpful and we are shopping around.
