Has anyone done any testing to see if older breakers trip easier than new ones?
I would assume the springs get weaker over time therefore trip easier. The only evidence I have of this is getting a service call for a breaker tripping ending up replacing it and all is fine.
I'm curious if there has been any scientific testing on this.

Greetings Alpelec,
I doubt anyone would venture into this testing as it would not be advantageous to the manufacturers. The reason manufacturers do not give an EOL statement is because the moment I said something needs to be replaced in 20 years my competitor would say theirs lasts 21 years. So other than PEARL, which is an association that deals with reconditioning and so on there are really no ongoing testing on this. Now, remember it is less about a "spring" in most of these as it is about the bimetal strip or electronic trip mechanism so I feel it would be less about the spring aspect of this.
