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.

    i agree that reply is indeed  even less useful than the sort of discussions we get  on here, perhaps there should be  a prize for most evasive 'answer'.

    The real answer is it is perfectly OK to use any old cable so long as it is suitable for the load and environmental conditions - orange arctic is fine for lawnmowers after all...

    Who would keep such reports - there's not a statutory duty to report such failures.

    If there was no evidence of problems why did JPEL think is necessary to delete the PVC (H05VV-F) option?

    The light-duty 318-Y cable is designed for use in domestic appliances, such as those often found in kitchens and offices, with a voltage rating of 300/500V. It is suitable for use with ordinary duty portable appliances such as radios, table lamps and office equipment where the potential for mechanical stresses and mechanical damage is low.



    The 318-Y range is manufactured in accordance with BS EN 50525-2-11 and European harmonised standard H05VV-F  (often misspelled as HO5VVF). Outside of Europe, the H05VVF cable is often called NYMHY cable.

    Round in circles I think here. I've had experience of water migration through PVC, I've pointed to some information from a cable manufacturer who says the same thing.

    Whilst I wasn't involved in producing Section 721 for the 17th Edition, I do know that it arrived in HD prior to it being included in 17th Edition - along with harmonization work of the respective cable standards which we now call EN 50525.


    You asked about "reports" - they won't exist for this, because there's nothing official. If a lead fails "PAT test" or similar, it's replaced, not reported.

    Is the problem again the lack of a harmonised standard for what's probably "arctic" flex and similar? (e.g. BS 7919 Table 44 as was) - which I believe was fully intended for outdoor use and as far as I can tell hasn't causes any problem when used for caravan hookup leads despite probably millions of metres of it being thrown across camp sites in all weathers for decades. As the harmonised standards don't directly recognise arctic it's had to be lumped into the same category as the poorest bedside-lamp flex and assume the worst for its outdoor wet weather performance. I presume the PVC formulations must be at least slightly different since they have quite different mechanical properties over temperature (i.e. arctic remains flexible where other types of H05VV don't).


    I still think we've ended up swapping a mearely theoretical problem for a real actual one - I'm not at all surprised that the caravanning community are collectively ignoring the requirement to use black rubber. It doesn't do BS 7671's standing much good though.

    The average owner will not have heard of BS 7671, but the manufacturers must surely know their obligations. So what happens to all those rubber flexes which are supplied with caravans?

    BS 7671 does not mandate black rubber. There is no requirement for the rubber to be black (or orange for that matter).


    BS 7671 can only specify standards that exist ... if there's a need for a standard for arctic flex, then the relevant committee should be lobbied ... it's not different to the ongoing discussion on SY and CY cables, is it?

    There are standards for testing that cables are waterproof enough to be immersed,  - both ANSI and EN, and the EN would be 60811-501 (more info on the Elend website here  ) I guess in due course after the Brexit dust settles well have a UK standard  as well.


    I'm not sure that many makers of PVC cables report  test results  to any of these standards however, but in an ideal world we could say 'any cable passing the waterproof test XYZ'

    Ukpn appoligies, not April 1st yet but I feel that a very high precentage of caravan/motorhome and campers don't actually know the dangers of connecting to their homes. I don't think they care much when ordering a new 25m orange cable from China or that they can buy an adaptor to plug the leisure vehicle into there home. Not even the manuals for vans have anything in them about the dangers. It comes down to education for consumers. Not anyone in this fourm as you all know. If they sell that adaptor they assume its safe. The times I have seen people on sites removing the plug from the caravan and starting to coil it up whilst still connected to hook up. Anyway I have gained a vast amount of knowledge about cables now, but I think with tech like the new devices for ev chargers someone can sell this as a safety feature at the right price to consumers, but the regs are slow to bring in new tech for use in this area. The first thing that should be done is to ban the adapter which allows them to connect to a house and make sure more caravan manufactures and dealers sell a caravan with a home hook up as part of the deal, everyone is a winner in the end.
