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?

    Thank you for all your replies.

    I will state again that the EV system is not our responsibility.

    However, there are three tower blocks with a 200A 3 Ph Landlord's supply (And each has a 400A 3Ph for the dwellings).

    15 charging points; 3 off one block and 6 from the other two.

    Loading calcs suggest the supply is sufficient, but that is down to the EV company and council clerk of works to verify.

    My question is, would it be reasonable to suggest that a 5% volt drop will be sufficient?
