I'm designing the lighting for our fall play. I want to find out how many amps our school draws on average, so I can subtract that from the Master breaker's amp rating (125 Amps), to find out how much current I can use without givin the school a blackout! There are two outlets I will be plugging into, each 3 phase, suppling 120 and 240 volts, and have seperate 60 breakers. The school has two electric meters, nobody knew if they were wired to seperate breaker boxes, or wired in series or parallel. Can the kilowatt hour reading be used to calculate average amps drawn? Meter #1 read 23954 kWh, and #2 read 23340 kWh. I do know that the kitchen (and it's electric draw) is on a seperate meter and panel, and heating is gas. Is the amp calculation possible? If so, how is it done?

This sounds like a large task! I would suggest speaking with a licensed electrician before doing anything. Have you talked with the school engineer? They may be helpful as well. Good Luck!
