Dimensions: The boxes are specified with length, width, and height dimensions, which vary depending on the number of ways and type. For example, compact consumer units may be available in 7, 10, 15, or 20 modules, providing ample wiring space and easy installation ( ). Material and Construction: Outdoor distribution boxes are typically fabricated from 2 mm GI sheet steel with reinforced channels for structural stability. Roofs are slightly slanted with overhangs to prevent water ingress, and doors are equipped with Godrej-type 3-position locking systems for security ( ). Protection and Safety: Many boxes conform to IP-55 protection, ensuring resistance to dust and water. Busbars and terminals are shrouded to prevent hot spots and accidental contact, and neutral and earth terminal bars are provided as standard ( ). Mounting and Installation: Boxes include studs and adjustable nuts for easy mounting and removal of pan assemblies. Knock-outs on top, bottom, and rear allow flexible cable and conduit entry.
