Wiring a van converted into a catering van? Help.

Who doesn’t love an E.coli van?

Thanks for the reply. There seems a lot of confusion on the topic that's why I posted the thread. I will opt to use 4mm then, it's just I have some 10mm at home . I will bond the LPG and the chassis and leave it as that I think.

This sounds far too much like design by guesswork than actually understanding what is needed.

Don't just guess at what needs to be bonded, test it and find out for sure.

If you wish to use 10mm flexible cable then there is nothing stopping you, however the minimum requirement would be 6mm off the top of my head.

That seems back-to-front. If the supply is TN-S from a genny with an earth rod, the installation earth will be approximately at the same potential as true earth even in the event of a fault to CPC within the van, as the rod does not carry the fault current. Therefore connecting the van body to the MET will not significantly increase that hazard. However, in the event of the line conductor contacting the bodywork due to cut or chafed wiring or being pierced by a screw etc, quite a plausible scenario, then if the bodywork is not earthed there will be a full 230V between body and true earth. In any case there will probably be many points of casual contact between appliances and the vehicle, possibly including via gas pipes. I would rather have a solid connection made with a cable.

As far as cable choice goes, how about H07RN-F as a tougher alternative to arctic PVC?

Thanks for the reply. I was originally going to use arctic flex. I'm now actually thinking if it's over kill. Everything will be conduit, I'm not running under the unit itself. It's all inside.
