I mentioned in another post that I would contact HSE regarding any issues reported to them arising from loss of neutral and EV charging points. They have responded and confirmed that there has been no incident reported to them. However, they were made aware of a small number of situations that were a result of poor or no load management. I should point out that this is HSE in Northern Ireland.
All EVCP’s in the public highway must be connected to a TT earthing system.
A PME earth terminal shall not be used (the supply and installation of earthing system and protection is the responsibility of the EVCP installer) as set out in section 6.2 of EDS 08 5050
Yet UKPN, as in you, appear to be telling us that using TNCS for an EV charger is perfectly fine.
Perhaps you can reference guidance from UKPN, the DNO, as to how to safely install an EV charger with TNCS earthing.
