Caravan diversity question

[Pretty Mouth]

What allowance for diversity, if any, would you apply to caravan hookup sockets?

The circuit will have just one hookup point, with two 16A sockets. It's a fair distance from the CU, so voltage drop is going to be significant. It would be good to keep the cable CSA down if feasible.

Is this for touring caravan hookup or for a static van

Touring

Surely two sockets is two hook ups.

Probably. Never done caravans before

Each socket should have individual rcd protection and individual circuit protection. See Section 708.

These are supplied at the hookup unit.

I'm fairly happy with the regs side of the job, I'm just trying to fathom whether I treat the circuit feeding the hookup unit as a 32A load, or if I can apply some diversity to it

Most touring hookups are often limited to 10 amps it's very rare to find 16amp in the UK, in Europe a lot of sites only offer 6 amp

I'm in the design stages/site preparation of something similar, but for four points.
Each point has a 16 interlocked, switched socket protected by a 10A type C RCBO, and I've allowed 24A as the design current.
The only long term heavy load likely to be drawn by a touring caravan is the electric space heating, which is usually 2kW max.

That is fine each outlet is individually protected.
