It's a long time since I retired but I have never seen a consumer unit with rcd & rccb's, so I would question whether you need both rather than rcd & mob's. However you have connected it according to the instructions so I would be interested to find out if that is the latest way of supplying mains electricity to a camper van.

Those are mcb's, they are just double pole mcb's rather than single pole ones.

Thanks for that I obviously did not look or read carefully enough. Done a bit of research & apparently it's a requirement for caravans under the 17th edition so presumably the same for campers. There seem to be a lot for sale that don't meet that requirement.
Excuse me for asking but the last sentence of the second statement says to " connect to a suitable earth "
Where would this be connected too ?
Wouldn't it make earth on the 240v live with to the battery of bus if connected to the body !
And isn't the block connected to earth via the hook up lead to the power outlet ?
Appreciate all corrections/explanations in advance

The suitable earth they talk about is the earth wire of the supply cable. It should also be connected to the vehicle body which as you say connects it to the battery negative. This is not a problem as rcd's, which will be disconnect the supply during a fault condition, work off AC ( mains supply ) not DC ( battery ) so a fault in the 12v side of the vehicle electrics will not affect the mains supply & the 12v circuits should not be supplied with mains voltage.
