My electricians engineer made a load calc. The math is counter intuitive to me.
He claims that 3 1000w lights on the same leg of a 480Y system is 3000/277
But that 3 1000w lights, one on each phase, is 3000/480v
Is this correct?
This is relavant as Intend to have 250+ 1000w 277v lights.
Am I looking at 250000w/277v or 250000/480v
My main is 800 amp 480v
Thanks.
