John Dirks Jr Posted January 16, 2018 Report Share Posted January 16, 2018 Do the NM cable manufacturers use any light oil as lubricant in the manufacturing process? I saw a drop hanging off of a conductor in the panel at an inspection yesterday. It was a light oil of sorts. I could not figure out how it had gotten there.

Jim Katen Posted January 16, 2018 Report Share Posted January 16, 2018 I don't know why or how, but I see it every so often too. Sometimes's it's amber-colored and sometimes it's a light blue. It always seems to be oozing out from inside the thermoplastic insulation. As far as I can tell, it's harmless. Quote Link to comment Share on other sites More sharing options...

Jim Katen Posted January 16, 2018 Report Share Posted January 16, 2018 Thanks for the link. When I've seen the stuff, it's been a total of a drop or two. If I ever see more than that, I'll consider it a problem. Quote Link to comment Share on other sites More sharing options...
