The IRC states that occupants must have access to disconnecting means - would that mean that in an apartment bldg where the main panel and disconnect is in a locked utility room the door should remain unlocked in order for the residents to access and turn off the main electrical disconnect? Also, each unit of the building has a subpanel, which is located in a closet. The building was built in the 40’s, so I am wondering if the panel’s locations in the closets is grandfathered?
Any advice? Thanks!
