Hey all,

I've searched the forums and read a good bit, but have a few questions that I need answered before I get a full grip on three phase wye and how its distributed.

For example's sake lets say we have 400 amp 3 phase, that is 400 amps per phase. My Cam tails are all hooked in and feeder is run to a moving light power distro. Now from my understanding between hots the voltage is 208V. So we can pull 208V power from Hots A>B and B>C and C>A? Also, how many amps of power can we pull? If we had a big enough power distro could we essentially draw the full 1200 amps?

Example two: Same power ratings and all except this time lets say we have a 200 amp distro ( so thats pulling 600 amps, 200 amps per phase) after the distro we run feeder to our dimmer rack. Am i correct in the assumption that the dimmers will have 600 amps (200 amps per phase) before anything goes haywire?

Thanks all,

Max
