> Wow. You have a great electrician. Went to Lowes and talked to the sales guy who is a retired electrician. Answer. Yes breakers go bad. It weakens every time it is tripped. Breakers are really a one time use but everybody just resets them. If there is a short in the buried line you probably will not even be able to reset it as it will re-trip immediately. Best course of action to replace. So I spent the $20 and bought a bottle Noalax. And yes I can put in a 100 amp since the line is large enough.

This is completely false. Breakers are absolutely NOT "one time use". Who ever told you this was making it up.
Also, they do NOT "weaken" every time they trip.
That said, breakers do fail. Many times the breaker connection to the panel stab weakens and creates a high resistance connection, creating a LOT of heat at the connection, which can fool the breaker into tripping under little load.
Many times this damages the panel buss and the breaker cannot be put back in that position.
