I am confused about closet storage space, (NEC 410.2). The part about a closet that allows access to both sides of a hanging rod defines storage space below the rod but not above it. As there is no wall when a closet allows access to both sides of a hanging rod, and as storage space is defined off the walls, (if there is no shelf) is there no restriction (except on fixture type) above a rod when the closet allows access to both sides? If there is defined storage space above the rod, where is it stated?
