So I'm almost done the rewiring of several parts of my house -- pretty much done and going to call for inspection next week but I noticed yesterday and today that when I have been finished working in the panel for the day and go to turn back on the main breaker, it doesn't "click" on very well. In fact I have to flip it three or four times with just the right amount of force in order for it to stay "on". I don't think there's anything wrong with the circuits or breakers in the panel (I've probably spent at least $300 on new breakers as part of this renovation) but now that I've flipped the main breaker a few times and got a feel for its peculiarities, is it worn out?
Is the wonkiness in the main breaker a concern or is it somewhat normal for it to need to be pushed up hard to solidly "click" on and stay on? And if I cannot find a new 200A main breaker for sale anywhere, does that mean I need a new panel?
Edit: Yes it's a Federal Pioneer Stab-Lok panel. a 32 space / 64 circuit model. I know these panels are hated but up in Canada I can still buy brand new breakers and the government regulatory bodies haven't recalled the panels... so while I know everyone hates them and they supposedly never work properly, they are legal to operate and I didn't want to replace it.
Update: main breaker failed today in the off state while I was working in the panel. Need to replace panel now to continue renovation.
