See attached. Are these breakers that you find in outdoor disconnects just regular breakers that would fit in a panel? Like if I say gimme a GE fat 2 pole 40, a Federal Pacific Stab Lok 2 pole 30 or a Zinsco 25 etc?
Or are they a special bread made for outdoors with a different mounting application?
It's there behind the breaker on bottom. Just pull down and away and it should pull off. With power disconnected of course.
Uh oh...I never turn off power when changing breakers. Am I being stupid? Or do you mean because it would be easy to kill the circuit inside?
BTW, the issue here was the inspector seeing the 50A breaker outside on a 40 max unit. I suspect the installers, confronted with two old square D panels with both cartridge and screw type fuses and a blade type disconnect labeled "furnace" inside; meant to track it all down at some point and then let it get away from them. It turned out to be the blade disconnect, threw a couple 40s in and all is good.
Well...to be honest I never changed that type of fuse before and didn't know which was hot, top or bottom. Suddenly I'm a rookie again and wondering if I'm about to make a fatal mistake, simply because it's old and I've never seen one before. I completely forgot about the NCVD that was right below my nose in my shirt pocket. In the end I slammed them in with insulated channel locks while bracing for a small arc flash or inadvertant fumble to ground...
