Busbar Trunking Systems: Flexible power for workshops

Business Impact

Fixed socket positions limit where you can plug in equipment. When layout changes - new machinery, different production lines - rewiring is expensive and disruptive. Busbar trunking provides power along a run with tap-off points that can be moved or added. Workshops and warehouses gain flexibility without the cost of multiple rewires.

The Details

Busbar trunking is a metal duct containing conductors; tap-off units connect equipment at intervals along the run. It is commonly used in industrial buildings, workshops, and large retail or warehouse spaces. Loads can be redistributed as needs change. Installations can be three-phase for heavy machinery or single-phase for general power.

Design considers total load, cable sizing equivalent, and fault protection. Installation must allow for thermal expansion and correct earthing. We design and install busbar systems for new builds and retrofits.",

Regulatory Reference

Busbar trunking systems must comply with BS EN 61439 (low-voltage switchgear and controlgear assemblies) and BS 7671. The manufacturer's installation instructions must be followed. Earthing and protection are critical - fault currents can be high in industrial installations.

Out-of-Hours Work

Trunking installation in active workshops often requires a shutdown or phased work. We schedule installation during planned maintenance, evenings, or weekends so production is not halted.

Thanet Business Context

Workshops at Manston Business Park, industrial units in Ramsgate, and warehouse spaces across Thanet benefit from busbar trunking where layout flexibility is key. We design and install systems for local businesses.
