I believe these colors to be correct. It is puzzling however that we have one brown and two blacks representing all three phases. Some three phase devices are phase sensitive (motors for example). Why not three different colors, e.g. Brown, Black and XXXX?

How do you differentiate between the two blacks? Is there a standard that mandates colors for three phase wiring?
