Supply for a camper van.

AncientMariner
A neighbour has just bought a camper van and I noticed that it is plugged into a garage socket whilst it is on the drive. I guess this so that they can do any fitting out it needs and keeping it's battery charged.


Having been reading the posts on EV charging, I am wondering whether similar requirements would apply to a regular 13A socket whether inside the garage, or outside the garage?  The supply is 1-phase TN-S

    in reality, I don't think there's a difference with an electric vehicle - if anything perhaps less of a risk because it's only 16 A not 32 A or more

    Indeed. As technology is moving on there less of a difference between caravans, EVs (and as davezawadi mentioned) mobile & transportble units - yet BS 7617 currently has somewhat differing requirements for each - some of which would be incompatible with the ESQCR in some situations (charging a motorhome from PME earthed system). I hope that no-one thinks it a good idea that the new PME CNE break detecting and c.p.c. switching charge points should come with a label that says "not suitable for use with electric motorhomes".


    I'll have to see if the DPC offers any improvement, but perhaps now would be a good time to start thinking about lobbying for a change to the ESQCR to allow PME earth to be used for caravans where TT isn't suitable and suitable precautions are taken to automatically disconnect the vehicle (and charge point if it itself has exposed-conductive-parts) from the PME system (including PE) when a broken CNE is detected.


    I still reckon it would be logical to build that protection into smart meters.
