ECN Forum Forums General Topics of the Trade General Discussion Area Never seen before NM-B cable

The other day I came across some NM-B cable, 8-3 w/g, which had wires which all had black insulation and were numbered one, two and three.

Is what struck me as odd, was that the insulation on all the wires was black, no white/gray for the neutral and bare/green for the grounding wire.

While I could not manipulate the wire enough to read the words NM-B, I could read the words 8-3 w/g and the outer coverings were consistent with sheathed cable.

Has anyone ever seen this before, or know anything about the source of the wire?

Thanks,

Joe Myers
