Had this happen in a supermarket that we do work for. The building got flooded and the manager shut off the mains in a Square D I-Line panel. The breakers had never been turned off since they were originally installed. When we went to turn them back on after the flood waters receded, the internal mechanisms didn't want to cooperate. Fortunately, shortly before the flood, we had built a new service in one of their other stores and there were a couple spares for future expansion that we were able to use. Moving parts don't always operate well when they sit for several years.
15 amp GE breaker tripped and wil not reset.

I went through the same thing last year with a 4,000 amp Square D main. I recommended that management establish a pm schedule for exercising/lubricating these types of breakers to prevent future outages and was looked at like I had two heads. I've come to learn that if it's not their idea, it can't possibly be a good idea. That's ok...I've got a bunch of "I told you so"s saved up that I'm looking forward to using.

Lubricating? As a PM? You will do more damage than good if you spray lubricants in breaker mechansisms. The only way to lubricate a power breaker is full disassembly of the mech.
