Has anyone seen this type of metal piece on a breaker
Circuit breaker lockout.
Junior’s on it! Lockout.
An appliance that requires an electrical service disconnect, such as an electrical water heater, and is not within the sight of the electrical panel, is required a lockable breaker unless a service disconnect is provided by the appliance. Like others mentioned, the bracket allows you to put a lock on the breaker so nobody could turn it on by accident while a tech is servicing the appliance.
Thanks for the help
I’m taught to call out those square d breakers…
Good catch! Did they tell you why?
Some people have had issues with them not keeping strong connections. Even if they appear ok, I note
There was a recall on them but only on certain production dates that needs to be verified. The affected breakers may not provide proper AFCI protection. I don’t know about the “keeping strong connections” part
