Kurt - Except under special circumstances, the USNEC does not use color coding for phase conductors. There are reserved insulation colors for ground (green, with one or more yellow stripes) and for neutral (white or "natural gray" [whatever that is]). Otherwise, your free to use whatever color you find aesthetically pleasing, provided there is no confusion about what conductor should connect to where. If your product requires a particular phase ordering, this should be identified on a wiring diagram and labeling of the connection points.

Tarver, PE ptar...@nortelnetworks.com -----Original Message----- From: Andrews, Kurt [mailto:kandr...@tracewell.com] Sent: Thursday, October 12, 2000 2:45 PM Group, Is there a standard color coding for 120/208V 3 phase wiring inside a product for U.S. use only? The product in question is ITE and I can find nothing in UL 1950 about color coding other than green/yellow must be used for ground. Thanks in advance for your help. Kurt Andrews
