What kind of "servers" are we talking about? If these are PCs we are vastly over rating the load.
What does the "clamp" say?
I have had a Kilowatt on this 24/7 cludge here (P4 2.8GZ, 2 hard drives, router, DSL modem, LAN switch, External DVD, monitor and an ink printer, electric train, amp/speaker on a UPS)
It shows 201 KWH for 1112 hours of running. That is 180w average draw.
He could quite easily run 8 machines on one 20a circuit but I could also understand why you would want to split this out across 8 separate UPS's.
If these servers are really PCs he is probably going to save money on his hardware using 120v since that is what they sell cheap and I doubt he would get 3p in a residence no matter what.
That is about a ton and a half of A/C the way I read it.
