I'm designing a re-wire of an existing TN-C-S outdoor facility which includes an EVCP installation pre BS 7671:2018, and changing out the TP+N DB and final circuit wiring for new. Whilst make making a large assumption prior to a site visit, I am not aware of the EVCP being TT install and expect the PEN to be providing the earthing arrangement. As I am providing a new final circuit supply, is this statutory that I remove the PEN and provide an an earth electrode to bring the EVCP upto BS 7671:2018? Irrespective this is best practice and will be employed.
BS 7671 "Wiring Regulations" has no statutory force.
They're starting to get some - for private rented dwellings they're a statutory requirement, likewise for any installation that contains parallel or switched alternative generation (according to the ESQCR). Even in other situations the contract with the customer is likely to require delivery of an installation that complies with the wiring regs - so you could potentially still end in court for failing on that point even if it's then a civil rather than criminal case.
In any event, if you're entirely replacing the circuit and wish to certify if complies with the current edition of BS 7671 (which is likely what the customer requires) then it makes sense to do it properly. That doesn't necessarily mean TT islands though - there are models of charge point that claim to detect (most) broken CNE conditions and disconnect all conductors (including the c.p.c.) in that event - which BS 7671 says is an acceptable alternative. If it's all outdoors and each charge point (& vehicle) can be well out of reach of anything connected to the CNE, my preference would be for TT.
