Why do people attach a metal bracket to a breaker. does it prevent the breaker from tripping?
Can you desscribe this “bracket”? Is it on top by the handle?
Nothing can “prevent” a breaker from tripping. Even a handle lock. The internal mechanism will still trip, even if the handle does not move to the tripped position.
A handle lock prevents a breaker from being easily turned off. As in the case of exit/emergency lighting in a store.
Maybe this is a critical circuit such as that, or maybe smoke detectors.
Pete. you answered it. I was right. You settled a bet with a know it all.
Hold-down bracket for a back-fed breaker?
The other “bracket” you might see is an interlock for a generator. It keeps two breakers from being on at the same time. (gen set vs utility)
