When installing a sub main swa with a separate Cpc to a distribution board should the Cpc go directly to the main earth terminal and not to the banjo on the gland then up to the m e t
If you have actually read any of BS7671 you should understand it is not an installation instruction book, you will not find wire X must go to terminal Y then Z. As with far to many instances multiple solutions can all meet the wiring regulations requirements. The regs would be too big to carry if it had to describe every permissible connection method to every conductor in all types of enclosures etc. It is the skill, knowledge and expertise of the person doing the work who will assess if their installation meets BS7671, and sign the appropriate certificate to say their work is compliant.
