UK switchgear and distribution box dimensions

UK switchgear and distribution boxes are typically modular, with standard module widths of 192 mm, and can be configured in height, depth, and width to suit specific electrical loads and installation requirements.Modular DimensionsMany UK low-voltage distribution panels use modular systems, allowing flexibility in height, width, and depth. For example, CUBIC's modular system uses a 192 mm module width, enabling designers to assemble switchboards to exact specifications for power distribution up to 6300 A . This modular approach allows for easy extension or modification of the switchboard without major reconstruction.Typical Enclosure SizesWall-mounted distribution boards: Often available in 13, 18, or 24-module configurations, suitable for residential or light commercial applications .Floor-standing switchboards: Can accommodate higher currents, with enclosures designed for up to 4000–6300 A, and are built to IEC 61439 standards .Service entrance switchboards: Eaton CMP switchboards, for example, provide a compact footprint with separate compartments for main service, utility metering, and distribution feeders, supporting up to 1200 A .Depth and Height ConsiderationsDepths typically range from 300 mm to 800 mm, depending on whether the board is wall-mounted or floor-standing .Heights are modular and can be customized; floor-standing units often exceed 2 meters for large commercial or industrial installations .Enclosure Types and RatingsStandard enclosures are CSA Type 1 or IP-rated for indoor use, with optional sprinklerproof or outdoor-rated versions .Schneider Electric offers PrismaSeT 6300 and other modular enclosures that integrate busbars, circuit breakers, and protective devices, ensuring compliance with IEC 61439-1&2 standards .SummaryUK switchgear and distribution boxes are highly modular and configurable, with standard module widths of 192 mm, variable heights and depths, and options for wall-mounted or floor-standing installations. Selection depends on current rating, number of circuits, and installation environment, with manufacturers providing type-tested enclosures for safety and compliance .
