Green crap

[rotaryfrk]

Does anybody know what that green crap that comes from the ends of stripped wires is?

I typically see it on really old wires. It appears to be oily and sticky???

It runs down the wires over years and years worth of time.

I've never seen it cause any problems. It's just nasty.

And it's not coming from a capacitor.

Could be a lot of things.

Adhesive from electrical tape
Oxidation inhibitor
deterioration of insulation
......

Try here for an answer
It doesn't mention wire but it's the same thing.

This green stuff is a thick liquid form. Oily, sticky, messy.

I've seen it in numerous electrical compartments.

I don't believe what I am seeing is Verdigris. But thanks for your input.

Is the wire in conduit? Sounds like the goo electricians use as a lubricant when pulling wire. It used to harden over time and really cause problems so they changed it to stay nice and slimey and the stuff I've seen used is green.

what about anti-ox? the stuff i have used is a light beer/brown color that probably is picking up dirt or just changing color over time to a darker almost black color.

good luck.

You will see this in most older Carrier machines. The wire vendor they once had used a lubricant when constructing the copper and insulation together because Carrier did a lot of in-line printing on the wires and they had to transverse many small pulleys in the printers. Over time this lubricant reacted with the copper and oozes out the ends of the wire at the connectors. Nasty! Calgon 10 degreaser makes quick work of it!

Everyone offered some good possibilities but, CHILLERSANDCONTROLS may have hit it on the head. The most recent time I've seen the Green crap was in an old Carrier gas pack. I believe I've seen it in other brands.

This Carrier was totally slimed up with it. It looked like Slimer from Ghostbusters worked on it last.

Anyways thanks for all your input.
