ARTICLE 312. CABINETS, CUTOUT BOXES, AND METER SOCKET ENCLOSURES
ARTICLE 312. CABINETS, CUTOUT BOXES, AND METER SOCKET ENCLOSURES312.1. Scope. Cabinets and cutout boxes, according to the definitions in Art. 100, must have doors (cutout boxes can also have telescoping covers), and are thus distinguished from large boxes with covers consisting of plates attached with screws or bolts. Article 312 applies to all boxes used to enclose operating apparatus—that is, apparatus having moving parts or requiring inspection or attention, such as panelboards, cutouts, switches, circuit breakers, control apparatus, and meter socket enclosures. The article does not apply to medium-voltage applications unless "specifically referenced" in another provision. One example of such a reference is 490.3(B).
