The Air Guard base that I work at is moving a new computer training center into what used to be part of the engine shop. There will be 17 servers with a combined load of 207.2 amps. We will have 54 computers that draw 8 amps each. Add to that, 108 moniters at 3 amps each. My question is this: What size 3 phase 120/208 volt panel would I need to support this load?

Is the lighting and HVAC and water heater for the bathroom and the other 20 or so other recept all being fed from some other panel?
Will all 17 servers and all 54 computers and 108 monitors be on 24/7?

I calced it at one outlet per piece of equipment and came up with 81 amps. If the 207 is a true number I would say that you'll need 400 amps. 300 if you can get it.

I came up with 321a per line: (207 + (54 x 8) + (108 * 3))/3 = 321. I also calculate 12a per server (207.2 / 17), which means 17 circuits. (Make it 18 for easy math and one spare.)
You can place one computer and two monitors on one circuit, requiring 54 more circuits. That means you'll need at least 72 circuits. I'd say you should go with two 200a panels.
