I need about 3,900 watts (estimated power at max load) to power a blade server, in the second bedroom of my apartment. What are my options? I have 12-gague wire. Everything in the bedroom is on it's own circuit. However, the receptacle in the hallway and on the other side of the wall is on another circuit. The blade enclosure PSUs have six C20 receptacles, and a single enclosure is rated for up to 8kW.
In the eyes of the NEC which is less of a violation?:
Also I'm going to need extension cords, because the closet I plan to put this in has no receptacles. None of these are good solutions, but I must do something right now. In the future I might be able to have an electrician come out to splice into the 240v circuit for my air conditioner compressor or maybe I'll get the server colocated in a datacenter. But right now I can't wait for any of these.
In the eyes of the NEC which is less of a violation?:
- Two tandem 15 amp breakers jumperred together (at the breaker) for 30 amps, with half the server PSUs plug into one circuit and the other half plugged into the other circuit.
- One double pole 30 amp breaker, with half the load on one circuit and the other half on the other.
- Re-wire the room for 240 volts @ 20 amps, by making the neutral hot. (Assume the fan, fan light, and LED A19 bulbs can handle 240v).
- Run new wire along the baseboard/wall (exposed) to a new 240 volts @ 30 amp circuit breaker. (Would need about 80 feet of wire).
