I've just seen a roll of UF (12/2 w/gr) that has a very unusual couductor in it. Besides the Black and Bare wires there is what appears to be a Red that was painted White on 'one side' (half the circumference)
(2) ......... In these applications, the conductor with white or gray insulation or with three continuous white stripes shall be permanently reidentified to indicate its use by painting or other effective means at its terminations and at each location where the conductor is visible and accessible.
I've noticed recently on colored wires that they are actually white wire with a thin coating of the darker color over the white. So, it is possible that when they were coating the wire to make it red that it didn't cover good. Then somebody at the plant only saw the white and loaded it in the machine as white. Just a thought.
Bill: That certainly looks confusing. On the new 12-2-2 w/g they use black and white then red and White with a red trace for two different circuits. However I have noticed with some cable when I use the seatek to strip it with the black coating will come off and there is a white wire under this black coating. Seems like the manufacturing process has cut some corners. -Mark-

I've noticed that starting to happen on some brands of cable over here as well, although sometimes it appears that the white inside is almost a separate layer bonded to the outer red or black. Strange that it's the more expensive brands being made like that now.
