Caravan hook up
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.
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.
