What is the norm on them these days?

A mixture of 12V from a leisure battery and 230V for when there is a
230V hook up. Inverters?


Caravans are IMHO just things that I normally queue behind on the A64 or
overtake if I get a chance.

This one is in Bristol and needs a rewire. So apart from hogging the
middle lane of the M5 on my way to get to Britol do any caravanners have
any tips on the best way to do caravan electrics?

Stranded rather than solid core cable, to reduce fatiguing and the risk
of snapping due to movement when on the road.

Back when we had a caravan (originally with 12V only electrics), we
added a mains input, mains sockets and a chunky transformer/rectifier to
provide 12V for the existing lighting and water pump.

We never added a charger, as we used either mains or the car and didn't
normally use a dedicated battery - but that was back in the days when
cars were simpler and you could easily bump-start a car with a flat
battery if you left the TV on for too long.

If there was no mains and we needed to disconnect the car (say someone
nipping out to the shops), we still had gas lighting and a foot-pump.
