RE: Mains Color CodesRobert, The only sections I could find in the NEC allowing light blue wire for neutral was in Chapter 4 "Equipment for General Use", article 400 "Flexible Cords and Cables". This would apply to flexible power cords for computers and such. I'm not sure what your product is or if this would apply. Hope this is helpful.
Brian 402-8. Grounded Conductor Identification One conductor of fixture wires that is intended to be used as a grounded conductor shall be identified by means of stripes or by the means described in Sections 400-22(a) through (e). 400-22. Grounded-Conductor Identification One conductor of flexible cords that is intended to be used as a grounded circuit conductor shall have a continuous marker that readily distinguishes it from the other conductor or conductors. The identification shall consist of one of the methods indicated in (a) through (f). (a) Colored Braid. A braid finished to show a white or natural gray color and the braid on the other conductor or conductors finished to show a readily distinguishable solid color or colors. (b) Tracer in Braid. A tracer in a braid of any color contrasting with that of the braid and no tracer in the braid of the other conductor or conductors. No tracer shall be used in the braid of any conductor of a flexible cord that contains a conductor having a braid finished to show white or natural gray. Exception: In the case of Types C and PD and cords having the braids on the individual conductors finished to show white or natural gray. In such cords, the identifying marker shall be permitted to consist of the solid white or natural gray finish on one conductor provided there is a colored tracer in the braid of each other conductor. (c) Colored Insulation. A white or natural gray insulation on one conductor and insulation of a readily distinguishable color or colors on the other conductor or conductors for cords having no braids on the individual conductors. For jacketed cords furnished with appliances, one conductor having its insulation colored light blue, with the other conductors having their insulation of a readily distinguishable color other than white or natural gray. Exception: Cords that have insulation on the individual conductors integral with the jacket. The insulation shall be permitted to be covered with an outer finish to provide the desired color. -----Original Message----- From: owner-emc-p...@ieee.org [mailto:owner-emc-p...@ieee.org]On Behalf Of Mavis, Robert Sent: Wednesday, April 05, 2000 1:28 PM To: Lacey,Scott Cc: emc-p...@ieee.org Subject: RE: Mains Color Codes I am running into a problem with UL not accepting the Brown/Blue color code due to UL 2044 and The NEC stating that the Neutral must be white or Natural grey. Has there been any updates to the NEC that allows the Euro Color code? -----Original Message----- From: Lacey,Scott [mailto:sla...@foxboro.com] Sent: Wednesday, April 05, 2000 4:48 AM To: Mavis, Robert Cc: 'emc-p...@ieee.org' Subject: RE: Mains Color Codes Robert, I have always found the European color codes (brown/light blue/green w/yellow) to be best for dual market use. UL and CSA seem to have no problem with the use of these. You will need to provide some kind of legend plate or tag explaining the color codes, as many U.S. electricians are still not familiar with these.

What are the allowable color codes for pigtails that come from a permanently connected apparatus to be connected to mains for US and Europe? Is there a color code that is allowable for both?
