I am looking for an article in the NEC or anywhere else which will help me with color phasing feeders. As I remember it 110/120 = black, white, green 220/240 = brown, orange, yellow 460/480 = brown, violet, yellow
Please help Thank you

| 110/240(aka- low voltage colors): A phase- black, B phase- red, C phase- blue, 208 stinger leg- orange, Nuetral- white
277/480 (aka- high voltage colors): A phase- brown, B phase- orange, C phase- yellow, Nuetral- gray
Grounding conductor is always green

You won't find in in the NEC because it is not required by the NEC. Jim

| Nothing in the 2002 about feeders. 210.4(D) discusses multiwire branch circuits where two voltage systems are present.
2005 NEC has similiar language in 210.5 and also 215.2, which will require some sort of marking scheme, but again, only when two voltage systems are present.

| Although there is nothing about color coding in 2002 NEC. Isn't there something about being able to identify one voltage system from another? I thought I read this, but will have to look to know.

| Thank you to all who have already replied. This seems to be one of those itmes which must be remembered through time in the trade. I thought I had it down, although took time away from work to relocate. Thanks again for helping me regenerate.

Yes, 210.4(D), but it doesn't apply to feeders.
