Crawl space NM cable

[kwired]

Dennis have you ever seen NM-C? I have never seen it for sale, I have seen some 1970's era stuff that had an insulated green wire like MC (or tray cable) and did not have the paper wrap, which I thought might be NM-C but I chalk that stuff up there with XHHN

Never seen anything that I know was NM-C either, though have seen what you mentioned, usually 12-2 with a 16 AWG green. The covering on that green wasn't conventional circular insulation but rather something that shaped to fill in the gaps of the cross section of that part of the cable. I don't believe these had any paper fillers, so maybe those were NM-C?

Lets start the hunt for a scrap piece of NM-C thats not also UF cable.
