Campervan RCD wiring

[Bigtasty1]

Hi all,

Hoping someone is able to help before I test this. Ordered 240 hook up for campervan and came with small consumer unit that had absolutely no instructions. I've tried to wire it up how I think it's me at to go but not 100% sure it's correct so thought I would check with the experts. Attached image shows 240 insert coming into unit and cable at top is a double socket. I'm not sure what the small box is below the trip switch on the right? Any help would be greatly appreciated, I'm a joiner to trade so not the most technical when it comes to electrics.

Thanks

This looks like a bit of a cheapo unit and I wouldn't use it if there are no instructions with it.
It's not CE marked either
It's too difficult to say if your wiring is correct.
The least I would do is get the installation tested.
You are in a metal box that could present a more hazardous situation than in a house.
Personally, I would get a branded unit from a reputable supplier.
