Worn out breakers

[AC\DC]

I got service request that an HVAC contractor requested breakers changed out because they were worn out. How does one gauge that unless the handle like sloppy? I don’t know how you can say they’re worn out.

Is the paint on the handle indicating amperage rubbed off or missing?

I have never heard of general use branch breakers wearing out. 1 pole 15A and 20A breakers are often switching duty rated (SWD) which means they pass the same test as light switches.

There are few old or cheap brands, like Pushmatic, where they don't stay closed when turned On, but nothing that causes breakers to trip easily. The bimetal used in breakers doesn't deflect enough to change its characteristic, just like thermostats can last forever.

But hey, as long as they are paying you there is no reason to argue with them.

I can’t believe Hvac guys they must just slammed their heads to make money. He just has to reset the breaker tripped from the previous unit short now and he never reset it.

That takes the money and run I get it, but I wouldn’t want someone to do it to me so I don’t do it to other people. I’ll tell him honestly there’s no need to change it and there wasn’t.
