EV Charging and Lamp Posts

richard64

We have a job wiring lamp post lighting in a private car park.

Somebody has decided that an EV point will be fitted at each lamp post and will supply the light.

When you apply the 3% volt drop for the luminaire, obviously the cable size increases substantially.

Any thoughts?

    Broadgage, you need to avoid a TNC-S supply if possible, thus a private TX. This will end up the best and in the long run cheapest option.

    We have no idea how often the neutral loss sircuit should be tested, 3 months, or whatever? 7kW chargers are no good for a car park where people park for an hour. We simply don't have the data!
