Not sure if this topic is still open or being monitored by folks here, but have a question. I am faced with this exact situation in a couple of months. I have a suitcase style single
phase distro that has a mix of single 15A and 20A breakers and outlets. The
venue I am setting up in has 3
phase power, so my plan, as some suggested here, was to
tie in my black and red, and cap or tape the blue
leg. The good news in my case (I think) is that my
feeder is #2 which should be good for 195A.
Here is my question, the
venue has 2 CAM panels, one is rated at 100A the other at 400A. I think I read somewhere that this means each
leg has that amperage
rating, and not the entire feed, is this correct ?? So in the case of the 100A panel (3-phase), if I only use 2 legs I get 2 X 100A, correct ??
Even though I won't be pulling more than 100A total in gear, I am thinking that since my
feeder is #2, and I don't have a main
breaker in my
distro, it is probably a better (not good) idea to cable into the 100A panel and not the 400A one, but again, I won't be pulling more than 100A in gear, so my
feeder should be fine.
Thanks
Neil
