I know we have all the crap in the air here, thus it comes down anytime we get rain.. but I looked over this can completely trying to find a way moisture could be getting in here... Everything a typical N3R panel should have was present & in decent shape... Then there's the conductors at terminations.... I'm guessing someone left the cover proped open for some extended period of time somewhere alog the line... This is the first time I've seen a panel with this in this city..(I've seen at least 20-30)
Steve... I thought of that at first also.. But the HO says nothing's been done out there since he moved in! (He says he's been there for 7 years, hope it hasn't been that way for THAT long!
