Copper wire discoloration?

[tewald (Terrill Ewald, CPI, MD# 31310)]

2004 home electrical panel in garage. Any ideas what would cause the copper to tarnish? Dampness of garage?

I don’t see an issue with it…Normal copper oxidation.

@tewald

wasn’t the bright copper usually seen.

How old is the panel? Pennies don’t stay shiny forever.
