We know that black, red and blue are the standard colors for ungrounded conductors on 208 3 phase as a general rule. When you go to 240 1 phase it is black and red. Now when you go to 240 3 phase you still have black and red, but do you still use the blue even though it is a 208 hi leg? This is on a delta system of course. Do some of you add another color such as orange or yellow above the blue to flag that the wire is a hi leg?
I think we got to where we used orange and blue to try and send a message somehow. How do some of the other people do this?
