Installing consumer units into campervan.

[Paul Cain]

I have bought 2 CPN Cudis consumer unit, a 4 way and an 8 way unit, which both came with a 100a isolation switch, I have also bought Cudis DP RCBOs 16a, type A, curve C, these are the 2 way type with no fly leads. I want to install these into my campervan.

I'm unsure which terminal are live and neutral on the isolation switch. I'm hoping that they are the same orientation as the RCBOs. If so am correct that I can connect the isolation switch and the RCBOs together with a DP busbar which I believe connects them from the bottom and loads going from the top of the RCBOs. I have attached pictures of the items.

The 2 way is for eletrical hook, mains coming into the van which will then connect to a Victron Multiplus 2 inverter/charger. Them from the Multiplus2 connecting ti the 8 way which will feed 3 Circuits to the van.

Terminal 1 is normally the live supply and 3 neutral. It is important the orientation of the busbar puts live to the correct terminal of the RCDs.

out of interest why do you think you need both in your camper?

Then if terminal 1 is live, then that busbar will not work as the isolation switch is not the same orientation as the RCBOs.

So what is the beat way to go about wiring this unit.

If you mean both units, they did have 12 way only 14. Si the 2 way was better use of space for me.

Should have read didn't have 12 way.

your busbar will determine the correct terminals at the main switch, just test for continuity with the busbar fitted at the main switch. The main switch is not polarity conscious, ie it makes no difference to the switch.

Thank you Binky, that's all I needed to know. So I can wire isolation switch up, to same orientation making a neater install as able to use the DP busbar.
