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?

    This is rather like expecting a mini to pull a circus caravan. By all means co-locate the lights with the charge points, so folk can see if they want to plug in at night, but unless there are very few charge points indeed, then there will need to be far more to consider than a slightly thicker cable. I'd start by verifying the available supply capacity with the DNO and go from there. The costs of more cable to handle voltage drop will pale beside any  requirement to subsidize a new substation transformer. You'd probably want to pull all 3 phases and neutral to each point.

    you cannot do this with out involving the design of the charger install and the DNO , so you need to liaise.
