I am installing a sub panel in an attic space to be finished. It will be fed from a 60A breaker in the main panel in the basement. Would you typically use a main lug panel or main breaker panel for the sub in this situation ?
Im for the Main breaker panel with an Isolated nutreal bar. The added disconnect and protection could only be a good thing. However, the more economical way to go is the main lug which has an iso bar already in it.
