14-position distribution box depth

The depth of a 14-position distribution box typically ranges from 70mm to 120mm, with some models offering adjustable depth up to 20mm.Standard Depth and AdjustabilityFor a 14-way distribution board, such as the Acti9/Multi9 series, the internal depth is designed to accommodate multiple MCBs or RCBOs while providing sufficient wiring space . Many modern distribution boxes allow adjustable installation depth, often up to 20mm, to ensure proper alignment with wall surfaces and ease of wiring . This adjustability is particularly useful in flush-mounted or surface-mounted installations.Internal Volume ConsiderationsChoosing a deeper box improves internal volume, which facilitates conductor splicing, easier cover installation, and compliance with wire-fill requirements . For a 14-position box, the depth must allow for:Proper spacing between MCBs or RCBOsAdequate clearance for neutral and earth barsSafe routing of incoming and outgoing cablesPractical RecommendationsSurface-mounted boxes generally have a depth of around 80–100mm, while flush-mounted boxes may require 100–120mm depending on wall thickness and wiring complexity .Always verify the manufacturer's datasheet for exact dimensions, as depth can vary slightly between models and brands.Consider future expansion and additional wiring space to avoid overcrowding, which can compromise safety and maintenance access . By selecting a 14-position distribution box with sufficient depth and adjustable features, you ensure safe, code-compliant, and convenient installation for residential, commercial, or industrial applications.
