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)
Nice write up by EV company, some good advice there. always best for supplies outside the equipotential zone to have an independent earth, but if we offer a separate earth return, and an example is a cable attached to an incoming supply sheath via a clip, this is ideal. Temporary builders supplies, which because an equipotential zone cannot be guaranteed are another example of using a separate earth return. So go ahead and feel free to use the facility.
