Volt Drop calcs max load help.

Looking at a job at the minute which is only for 3 IP rated double sockets down a garden.

Problem is the garden is almost 35 meters long, then its another 21 meters from switch fuse in the house.

Anyway, what I need to double check is when choosing cable sizes for my runs, what is best to allow as load for the final circuit VD? Take it per socket or allow for the breaker rating?

At the minute its looking like 6mm out to garage then 4mm to the sockets, all in 3 core SWA i might add.

Had a little chuckle when i priced up all the gear to do it, and thought thats some dosh for a few sockets in the garden:deal:

Any ideas of what is likely to be plugged into them???

3 x double sockets = a potential 6 x 13A loads = 78A max size CPD for sockets 32A

I think you should go for 32A max

HAHA, that would make it a little easier LOL

As they're in a garden area mainly would probably be items such as mowers etc. But one is in a patio area which she uses for BBQs so could be anything they fancy taking down the garden really.

You must be a mind reader Lenny!

She actually mentioned heaters and I politly suggested otherwise. But I know that won't stop em.
