But it does bring to light what seems to be the crux of my confusion. My little chart showed 3 lights and the legs that it would be using to get 208v. Horizontally is a unit and the columns show the amp draw for that leg. ......leg X.....leg Y.....leg Z Unit 1...11amp...&...11amps Unit...

Sorry, you missed I'm an idiot and on very little sleep. Thanks for your patience.

Thank you for your response. Just a follow up. You list 33amp *sqrt3 = 57amps per leg. why 33amp to start? Power Distro wiring would distribute power as: Leg X...leg Y...leg Z 11a...11a ...11a...11a 11a.....11a It wouldn't be 22a * sqrt 3 = 33amp per leg Where did the additional 11amps...

Hi all, a pretty simple question. I want to be able to calculate the load on a 100amp 3 phase service. As an example if I have 9 lighting fixtures that are rated @ 11 amps 208v each (auto ranging 200-240v actually but service will be 3 phase so 208v ish) Putting evenly across each leg x,y,z...
