Hi guys could do with a little advise on a rather large job re-wiring lamp posts in a car park. The supply will need to cover a distance of around 120M from mains to sub board where floods are already wired in 2.5mm SWA on 2 circuits the furthest travelling another 123M the other travelling around 75M.
Ive worked out that the sub feed would need to be of a 10mm CSA based on the distance from mains to sub board but how do i take into account the extra length of smaller run out from the sub board?
Cheers :crazy:
