Dimensions of the Low-Voltage Distribution Box in the Computer Room

Typical low-voltage distribution boxes in computer rooms are modular, with widths ranging from 600 mm to 1200 mm, heights from 1800 mm to 2200 mm, and depths from 400 mm to 800 mm, depending on the panel type and capacity.Typical Panel DimensionsLow-voltage distribution panels are designed to be modular and space-efficient, accommodating main service compartments, metering sections, and distribution feeders in a single assembly . Common dimensions for freestanding switchboards and distribution boards in computer rooms are:Width: 600 mm to 1200 mmHeight: 1800 mm to 2200 mmDepth: 400 mm to 800 mm These dimensions vary depending on the number of circuits, busbar size, and whether the panel includes auxiliary equipment such as metering, lighting control, or motor control centers .Installation and Clearance ConsiderationsWhen planning a computer room LV distribution box:Front clearance: Minimum 1000 mm is recommended for safe operation and maintenance access .Side and rear clearance: Typically 600 mm to 800 mm, depending on local regulations and cable entry requirements.Top or bottom cable entry: Panels are designed to allow either top or bottom entry for service cables .Mounting: Panels can be floor-mounted or wall-mounted, with front access for operation and maintenance .Standards and ComplianceLV distribution boxes in computer rooms should comply with:IEC 61439 for low-voltage switchgear and controlgear assemblies .SANS 60947 for operational safety and electrical performance .IP protection ratings (commonly IP54 or higher) to protect against dust and moisture .SummaryFor a computer room, a freestanding LV distribution box typically measures 1800–2200 mm in height, 600–1200 mm in width, and 400–800 mm in depth, with adequate clearances around the panel for safe operation. Modular designs allow flexibility for future expansion, top or bottom cable entry, and integration of auxiliary equipment such as metering and control panels .
