ECN Forum Forums General Topics of the Trade General Discussion Area 3wire 3 phase grounded service

Does the equipment need to be specifically rated for 3 phase service? Or is it sufficient that the equipment be rated for the voltage to ground?

As an analogous question: is a common 240/120 single phase residential panel suitable for use when supplied from two legs plus the neutral of a 208Y/120 supply? Or does it need to be labeled for that application?
