EV Charging and Lamp Posts

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?

  • I’ve been getting up to speed with the code of practice for EV charger installations recently as I’m going on the C&G 2919 course in a matter of weeks. I actually logged in to ask an EV question myself. I haven’t got it to hand but from memory I’ve got two things to say but first I’ll give myself a get out of jail free card that I’ve not yet attended said course and I’m a house basher, I don’t do street furniture 

    so voltage drop being a product of current and resistance, as per usual your three options when faced with this problem are as follows, 1) increase cross sectional area of your conductors. 2) and or decrease your design load, can a 3.5KW charger be installed instead of a 7KW one? 3) don’t install the circuit.

    Now I’ve been looking in the code of practice yesterday and I’m sure it says in there somewhere that EVC installations should be supplied individually but it can supply multiple EVCs, perhaps with this in mind utilising a street lighting circuit would not be appropriate.
