    Can anyone shed information on this white round thing with the perforated mesh in the middle - is it just a breather/vent ? its only as big as a 10p piece - i am looking for a way to feed a cable (twin and earth) from this part of the van (near the rear) under and along towards the cab and back up, don't want to be blocking anything important off but don't fancy drilling any holes (n)

    It's a gas 'drop vent' to allow gas to escape .. it has a grill to prevent rodents getting in.. you could use it for a cable provided it doesn't block it completely.

    Important.. don't use twin and earth.. use a 3 core sheathed flexible cable.

    To be honest though I'd drill another hole next to existing ones for the cable and leave the vent as it is ......Their there for a reason

    Very good advice. For a motorhome you need a flexible cable.

    Why not stick it through the existing holes? looks like there could be room alongside those pipes;)

    Don't use the solid twin and earth (the flat domestic cable) it needs to be flexible use something like your hook up cable or smaller depends on the load you will be feeding. The solid will snap when flexed and it does not conform to the electrical regs!

    Depends what you're connecting this cable to. Domestic electrical accessories are designed for T&E, solid conductor, cable and don't handle flexible cable very well. Have a look at a connection unit. The supply cable terminals are different to the load terminals. The former are designed for solid conductor cables and the latter flexibles.

    I wasn't referring to the cable type, but seeing as you mention it, 2.5 sq mm is available in a 7 strand formation which, it appears, would fully comply with the CI Regs. Also, if you read the Reg, flexible appears to be an alternative cable type to stranded.

    The comment I made concerned what the cable would be terminated in. The type of cable to be used (stranded or bunched flexible) 'depends' on this.

    As I understand the regs.. you can either use

    sheathed flexible cable, or stranded cable run in non metallic conduit..

    Twin and earth should not be used..

    Its already done, just finished the job, the cable that was connected to the 240v sockets (original from new) is the same that i have used, i have just tapped into the original socket using 3 core flexi cable (like the hook up cable) and added another 240v socket at the opposite end of the van (y)
