Where can I find the colors for 460 volts in my 2005 Electrical Code book? Where can I find the phase colors for 460 volts anywhere? I know B O Y. Brown , Orange Yellow,; but where is the phase colors listed? Any help would be great.

  1. The USA National Electrical Code does not specify colors for 3-phase wiring. Some state and local codes may.
