At present there are 3 different systems in this building, 208/120 3ph , 480/277 3ph, and 240/120 single ph. Most of the 120/208 has used the black red blue color code, and the 277/480 has used the brown orange yellow colors. Coworker has stated that we cannot use the black red blue again for the 120/240 system that has been installed.
What colors would you use for this system? is it even required like he said? I don't have my code book in front of me right now, but I do know we have to have a somewhat of a different color scheme going, but I thought it had mostly to do with the voltage per se.
