Distribution Cabinet Installation

Distribution panel (box) installation requirements are as follows: Distribution panels (boxes) should be made of non-combustible materials. Open distribution panels may be installed in production areas and offices where the risk of electric shock is low. Enclosed cabinets should be installed in processing workshops, foundries, forgings, heat treatment plants, boiler rooms, and woodworking shops, where the risk of electric shock is high or the working environment is poor. In hazardous work areas where conductive dust is present or flammable or explosive gases are generated, enclosed or explosion-proof electrical equipment must be installed. All electrical components, instruments, switches, and wiring in the distribution panel (box) must be neatly arranged, securely mounted, and easily accessible. The bottom of a floor-mounted panel (box) should be 5-10 mm above the ground. The center height of the operating handle should generally be 1.2-1.5 m. There should be no obstructions within 0.8-1.2 m in front of the panel (box). The protective wire connection should be secure. No exposed live conductors should be allowed outside the panel (box). Electrical components mounted on the outer surface of the panel (box) or on the distribution panel must be reliably shielded.
