Amps Are All Askew
Dear Swami, I'm stumped (and so is everyone I've asked thus far). I can't seem to figure out the power draw on a show. Here's the layout: 15 - VL4k spots @ 208V; 16,000W each = 24,000W 3 - Clay Paky Alpha 800 @ 208V; 1200VA each = 3600W (assuming PF = 1) 12 - S4 Series 2 Lustr @ 208V; 168W each = 2016W 3 - Colorado Solo1 @ 208V; 62W each = 186W So that's: 24,000 3,600 2,016 186 29,802W total The incoming voltage from the service is about 117V phase-to-neutral and about 202V phase-to-phase. When I do the math (29,802W ÷ 202V), I keep coming up with 147.5A total, or 49 amps per leg in a balanced 3-phase system. What my meter is telling me is about 82 to 86 amps with every light in the rig on full. Unfortunately, audio and video are using the same service, so that pushes it up to the low 90s range, and it's a 100-amp service, so it is way too close. Am I missing so...
