Supply for a camper van.

ebee:

I does seem reasonable Clive but I`m afraid not. The just Joint the N & E then bring it to the cutout as TNC-S with adjoining properties not far away they also effectively have a pretty much TNC-Sish supply too

That was exactly my experience. When my service cable was "PME'd" under the lawn, I asked why they would not repair the poor joint. I was told that all the lamp posts are "PME'd" anyway so it wouldn't make any difference. I assume that meant that there were N-E bonds at each one +/- some form of earth connexion. So if you don't know, you'd say TN-S 'cos that's what it looks like.

UKPN:

Any infringement of the ESQCR regs will be dealt with firmly and swiftly by the DNOs. As was witnessed when the picture guide book came up with the hairbrained scheme to "improve" the DNOs network. This was the horror whereby many rods were to be installed in peoples front gardens and patios to "reduce" an already low impedance. Ill conceived, needless to say didnt get past the sham "public" consultation period. 


Clash head on? I think our poster is flattering himself, there will be no clash, if incidents are reported to the DNO regarding  a PME breach the consumer will be at risk of losing the facility on safety grounds. (By law)


"its the supplier who has the duty to comply" Not true, It is the designer/specifier/installer who must be clear of their of their reasons and acknowledge their accountability in making such a decision.


Regards UKPN. 


 

If you have a look at the specific Regulation 9 of the ESQCR, it's clearly a duty of the Distributor ...


Nothing in the Regulations serves to impose a duty on the consumer in this respect.


Whilst Regulation 26 may permit the DNO to disconnect, in this case there's not a problem with the  consumer's installation, as it's only what's plugged into a socket-outlet that arguably causes a potential safety problem.


... which is probably why 1000's of caravans and motor homes are plugged into PME installations at homes around the country, and nothing is done about it ...

Surely a motor home is a motorised caravan, so is subject to section 717, and the parking space section 707. The dangers are exactly the same as electric vehicle charging, and a shock between the vehicle and the ground around it, or PME earthed extraneous parts close by, is equally possible. I have not noticed many owners taking any notice of these regulations in my locality, either with motor homes or caravans.

From BS 7671 perspective, it's effectively a caravan.


But I agree ... 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.

That's because the average householder doesn't even know those sections exist.  There's no requirement for a householder to comply with any particular British Standard when putting a 13A plug into a 13A socket.


That's the daft thing about it all.  We have the ESQCR and BS7671, and all their ridiculously complicated rules.  But the average householder knows nothing about them.

The legislation in this particular case influences the intendant "British Standard Requirements" ... and so the circle keeps being "squared".

Quite so. Why would an ordinary person think that there were any restrictions as to what may be plugged into a 13 A socket? It isn't obvious that an EV shouldn't be plugged in via an extension lead even if it goes across the road. Nor for that matter is there any reason why an ordinary person would know that the total load in a double socket should not exceed 13 A.

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
