is it common in to have a sub panel in apartment that has no main breaker. The panel outside has main going to it from meter but subpanel inside has no main, doesnt this violate the 6 disconnect rule?
A sub panel does not need a main breaker if the breaker panel feeding it is on or in the same building.
Sorry, maybe i'm the only one who don't know the 6 disconnect rule?
