I have a 200A General Switch mains panel in my house, probably dating back to around 1979. I have already replaced two breakers due to frequent tripping (well below rated current) and flickering on a lighting circuit.
One of them had what appeared to be arcing/ carbon tracking on buss contacts.
Due to these issues should I look at replacing all the breakers?

but breakers come loose and resultant arcing can develop pits.
