Need some help here, as things get a little blurry with the phase angles and everything. But here's my question: I have a 208V/30A 2 pole breaker, feeding 10A to each phase. i need to calculate power. I have 3 methods and need to know which one is correct. 1.) 208V x 10A = 2080 Watts (total power used by both phases) 2.) (208V x 10A) for 1 phase + (208V x 10A) for the other phase = 4160 Watts for both phases 3.) (120V x 10A) for 1 phase + (120V x 10A) for the other phase = 2400 Watts for both phases OMIT POWER FACTOR AND ANYTHING ELSE PLEASE. I would like to eliminate confusion, because coefficients are easy to understand. and please just answer my question directly.
