Wire corrosion

If it’s an underground service, it sounds like sulfur gases from ground water entering through the riser below the meter and then flowing into the panel through the conduit. The top of the riser is supposed to be sealed to prevent this, but that rarely happens.

I’ve seen this many times.

Yes, as always.

So is there a concern to be had with this condition?

The original concern was possible Chinese drywall.
