Caravan hook up

Former Community Member
Former Community Member
Hi I am fitting a caravan hook up on the wall next to  the dno incomer box. No wires exposed. Do I still require an earth rod. The earth bond will be prob 1 ft long inside so not exposed. I know if I fit the box away using swa then yes earth rod would be used.

    Interesting combination.

    Yes, I am struggling with the idea of a socket at both ends. It looks good, but I am also having difficulty identifying the member on the NICEIC site.

    If you have a look for caravan electrical equipment and cables on the internet you will soon realise hardly anything on offer actually complies with the requirements of the Wiring Regulations BS7671.

    Or indeed BS 7671 doesn't comply with accepted good practice in the caravanning sector - the vast majority of electric hook-up leads are bright orange - so they can be seen clearly against the grass and so greatly reduce the chances of trips or being mowed over ... yet BS 7671 demands rubber types (H05RN-F or H07RN-F or equivalent) which as far as I can tell are only available in matt black.


    And as for attempting to apply the general requirements of BS 7671 on top of A721 for the 12V system is a complete non-starter.

    That is an interesting regulation that may be worthy of discussion, due to what Eland Cables say on their website:


    The H05RN-F cable is the 300/500V variant of the H07RN-F 450/750V cable, with Class 5 flexible copper conductor cross-sectional area sizes of 0.75mm2 and 1mm2 only.
    H05RN-F Cable | Eland Cables


    So, how can H05RN-F cable meet the requirements stated in The Wiring Regulations BS7671 for a caravan hook up lead to have a minimum conductor size of 2.5mm2 ?

    I have seen the 16 amp plugs and sockets reversed, on one occasion it was on the supply cable to a hired inflatable bouncy castle at a children's birthday party in a private garden.

    Like EV chargers technology could change the regs on this subject as they changed the EV charger instalation due to its demand and promoting a cleaner earth as in planet.

    The answer is to park the caravan inside your garage at home and use a garage socket.


    That resolves earthing issues and those of the socket getting wet, but it ain’t going to resolve the issue of the type of socket not being suitable within a domestic property or for that matter not actually being suitable for use on a caravan park pitch, because it’s not interlocked.

    Got me thinking about my caravan.

    It's  two year old touring van parked next to garage. It's built onto a Al-Co metal frame and timber and plastic construction.

    Has a DP RCD and DP mcbs. Our supply is TT 3Ø 100amp per phase. To caravan is 2.5 6242Y from 16A mcb to Canavan supply box with 30mA DP RCCD.

    I think everything is covered at home!


    Out and about, we have never been on a site but in fields using only battery power (large solar anel on roof) and gas heating/cooking and hot water.

    Water from stand pipe to 50l water barrel and onboard WC cassette emptied into elson point.


    None of this nanby-pamby going to sites with showers, toilet blocks and washing machines.

    AJJewsbury:
    In what way is this suggestion different from hundreds of items of street furniture?

    Possibly it's somewhat more likely that someone will take a firm grip of a caravan door handle/frame while entering/exiting (probably many times and hour if loading/unloading) - I suspect the numbers for touching the local lamppost would be somewhat lower.


    Also the additional electrodes for street lighting are likely to be reasonably effective given the small loads - a caravan hooked up to a 100A domestic PME supply won't have that luxury.


       - Andy.


    Here in London we have EV charging points attached to lampposts. This firm char.gy take on average 90 minutes to install them, and mention that earth mats and/or rods might be needed.

    Just to avoid possible confusion - I don't think that's a "TT kit" - just a ready-made assembly of what usually goes inside a caravan - the G/Y will be a bonding conductor to the chassis rather than to an earthing conductor for an electrode.
