120/208

hi folks,

I am kinda confuse when calculating power for 208v systems. Let me know if I am wrong in the next situation:

I have 5 moving lights consuming 750watts each, on 208v.

Each fixtures will suck 3,61 amps on 2 different phases. So by additionning 5 fixtures, i'd get:

phase 1 : 14.44amps
phase 2 : 10,83
phase 3 : 10,83

Then, if I add 2 750w lekos connected on the third phases. I would add 12,5amps to phase 3.

This would also give me a total of 12.5amps of return on my neutral cable.

Is that right?

Your question is not clear. Are the movers three phase or single phase loads? If they are single phase, how do you intend to divide the movers among the three phase source?
