What is the three phase color code for 208v?
25/02/2006 · Orange is reserved for the high leg of a 120/240 three-phase system, with A-B = B-C = C-A = 240, A-N = C-N = 120, and B-N = 208. Wherever the N is found, and B is also found, then B must be orange. If there is no N in a box or other device, so there is no possibility of tapping in a 120 single-phase load, then B doesn't have to be orange, but it is a good idea.
