Default Sticky Black Coating On Cu Grd Wires IN Panel

1996 house in Palm City, FL. The drywall is original. Anyone know what might be on the bare grd wires?

Since it's bare copper it's some sort of reaction. At first I thought of Chinese drywall but I don't believe that the problem goes back to the 90's.

Where is the panel located? Any corrosive material stored nearby?

No, you didn't call it sticky!!
On a side note, I ran into this a while back and asked the same question on the MB. Came to the conclusion that because it was in the laundry room the bleach and other corrosive products were attracted to the bare metal.

I would think that generally it would take some electrical current to generate this type of thing. There is all kinds of exposed copper in laundries with no black sticky stuff around!

My want to have the ground checked.

Chlorine bleach is a strong oxidizer.

The 2 main panels were in a garage mounted on an exterior cmu wall with drywall partition on the int.

There was no evidence of any corrosive items stored, and the laundry room was in the house.

The immediate area adjacent to the panels was prev used for cabinet fabrication.

So, we have unfortunately gotten nowhere yet on this one.

Then it probably is down to sampling and testing.
