    Yes, several times. These breakers need to be used at least once per year or they need to be dismantled & cleaned & lubricated. In particular the pawls on the manual charging mechanism stick.

    Yes – problems with CB being closed when it indicates open.  Current solution is to fit long allen bolts to ensure cb can be used as a point of isolation
