Insulation green stuff
Insulation green stuff
(OP)
I have a significant number of control cable wires. Standard gray control switch wiring #8 and #10 that is oozing a green sticky substance. It has no odor. Has anyone seen this before or know what it is?

I think you may get more responses in the electric power engineering forum.

Long Shot — “Green-goo ooze” is a slang term for electroendosmosis, which is mentioned in an NEC fine-print note. For it to occur, though, there has to be DC potential, moisture and thermoplastic {e.g., PVC} insulation.
99NEC310-13. FPN: Thermoplastic insulation, where used on dc circuits in wet locations, may result in electroendosmosis between conductor and insulation.
