Hi, I am not too familiar with campervans but I would certainly think you would have to turn on the RCD. That is certainly the case with my caravan.

I think it must depends on the set-up. We just plug in & power is automatically switched to the hook up from the leisure battery. It's the only system we've known.

Mains power comes into any vehicle or caravan via a small consumer unit which has an RCD in it, that is the one I was referring to. It is necessary for safety as it will trip if you have a malfunction of any electrical equipment. Whether there are any other switches in camper-vans or motor-homes I have no idea as I've never had one, but I do have some understanding of electrics in general.
If you plug in the EHU and the RCD has tripped or been turned off, none of the mains appliances should work.

Can't speak for your camper, but the breakers in my caravan naturally remain 'on' (unless a fault trips them) all the time, not needing resetting after last disconnect from EHU. I just hook up the EHU cable, switch on control unit master switch, heater and charger switches as required and all sorted.
The EHU bollards on sites are another matter, not a lot of standardisation on those it seems! Some are just plug and go, others plug in and rotate to switch on, others plug in then flip breakers on. Sure there will be other types as well!

Most Motorhomes and Caravans have "latching" RCDs that don't trip when power is lost, they only trip when an earth fault is detected so they remain closed when you disconnect the mains.

My RCD has never been off except when being tested. Why would you want to turn it off? Plug in to EHU and check that the kettle is working.

To be safe you should plug in to the EHU and test that the RCD trips to ensure it is working properly before you put the kettle on.

Testing the RCD as Saxo says is very useful as it confirms there is power coming through. If power is not present the test button won't trip.
