Your at a house all alone and don't feel like going up and down the stairs trying to figure out what breakers turns off what, so you shut the main down out of laziness..
Funny you should mention that. I have a main switchboard with CT cabinet ordered for a building that is being renovated. The 1200 main breaker will NOT move.....can't turn it off. One of my guys, a 200 pound man stood on the handle and it wont budge:laughing:...........shutting off the main sometimes will not reset..:no:
