Opened breaker panel and saw this
So I’m not an expert but I am aware that there are several issues here, one being that it’s old (the actual breakers are newer—cheaper update). I had a some painters refresh some paint recently and think they didn’t cover the area while painting and/or some of it may be old.
I called two electricians. one who I’ve used before, he told me that I didn’t have to worry about it. The one I cold called said I should replace the whole box for $1700.
What’s the what here? Is this urgent?
