Caravan hook up

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.

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.

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.

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.

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 ?

PVC cables are not suitable for being left in standing water ...


So I wouldn't necessarily say that it's BS 7671 not complying with good practice - and also consider that we are talking about the implementation of an HD here. So, an assembled product complying with LVD should comply with relevant ENs and HDs unless the manufacturer self-certifies otherwise ?


Agree on visibility, and also would like to point out there's a huge price difference between H0xRN-F and H0xVV-F.
