When wiring lighting or other devices on a 277v system, what colors go to what phase, in what order? I know the colors, but was asked on a test for employment this question, and I can't figure it out on a 3 phase system.

Brown, Orange, Yellow, for the three hot phases in that order, and Gray for the Neutral
Ok thanks
