Is there actually stuff in BS7671 about caravan wiring?

Â*From 17th ed (as I don't have 18th ed)

721.421.2

The wiring systems shall be installed using one or more of the
following:

(i) Insulated single-core cables, with flexible class 5 conductors,
in non-metallic conduit.

(ii) Insulated single-core cables, with stranded class 2 conductors
(minimum of 7 strands), in non-metallic conduit.

(iii) Sheathed flexible cables.


It's not what cables to use that bothers me. It's more what advances
are there in making it more user friendly. I had never even considered
that all the lighting should be 12V.

Hmm, there is a whole debate there.

Most modern ones have a 'smart' box which controls various things,
including a user control panel. Just how much of functionality is
required is open to debate. You could implement most things with just
switchers and simple sensors (for water level, voltage sensing etc). No
need for LCD displays and menus. Perhaps a simple voltmeter.

If you look on YouTube, there are videos where people have done their
own conversions and wired up simple but adequate electrical systems
without using a commercial controller.

I might be overestimating what she wants.
