Recently sat the 18th Edition Course and of the understanding EV Charging points shall be fed from a TT Supply. PME is acceptable only when feeding any other equipment ie Lamp posts Ticket Machines for example and providing Type A or Type B RCD is fitted and the Charger point is then to be separately spiked. Just looking on the attached and a company called Pod Point suggest TN-S is acceptable with no need for an earth spike. Wondered if anyone else has come across this diagram and can confirm TN-S is acceptable without the spike (see - page 2)
If you are going to make the charging point a TT Island then you need to carefully follow Graham Kenyon's advice about your electrode being spaced away from any underground metallic pipework connected to a PME earthing terminal.
Also you cannot have your TT earthing system being simultaneously accessible to another earthing system, see Regulation 411.3.1.1. So you may need to change Class 1 light fittings adjacent to Class 2 and enclose any nearby pipework.
