If you are planning to rewire one, there are two main approaches.

One is to use a 'control box' and associated panel. People like CBE,
Sargent make them.Â* These tend mainly to control the 12V side and
interface with the vehicle- especially in motorhomes. They generally
do have some mains element but it is generally just housing the RCD
and MCBs, rather than actual control.

The other approach is less integrated. Basic wiring with fuses or
circuit breakers etc and sensors for the water tanks. People like CBE
make the various bits you need.

Our previous mh had a Sargent Box, it was large but seemed very good.
We didn't have any problems, other than the water level sensor was
sensitive to lime scale. Adding a larger cathode (reducing the current
density and therefore scale / area over time) solved this. The new one
is a CBE. It is more compact and, so far, has been fine.



I think I need to find out what she actually wants! Her sister who lives
in Barnsley asked if I would do the job so I thought I had better do
some research before I say yes.

But thanks you have provided some interesting info for my research.



Might interior and exterior photos be help the planning?

Or essential if you are expected to sleep in it
