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)
The EV Charge points are planned to be installed in the service yard of an office block. The mains supply is quoted as TNS and is fed via an independant Transformer located in the service yard off the DNO network. The Transformer also has full generator back up with UPS back up covering all critical equipment on site like comms rooms. Sounds to me from the advice that we should spike it and assume TNS as a PME even though it will never be converted to a PME in future but cannot offer any guarantees.
