Standard for high-voltage (HV) and low-voltage (LV) mains cables. 150mm: Required for cables larger than or when encased in concrete. Free Cable Sizing Calculator BS 7671 - ELEK Software
The calculator should output one of the standard metric duct diameters used in UK civil and electrical works:
Unlike overhead lines or surface-mounted trunking, underground ducts are unique because they are largely inaccessible once installed. Buried beneath concrete slabs, tarmac roads, or manicured gardens, they represent a "one-shot" installation.
