EV CHARGING EQUIPMENT

John Peckham
I am hearing from my network of contractors, that have actually read the new 722, that they have been asking charging equipment manufactures for documentary proof to comply with Note 5 of 722.411.4.


They are getting knocked back for asking or in one case a Declaration that says the particular device complies with BS 7671. I think that is wrong to declare that as BS 7671 is an installation safety standard and not a product standard. I believe that as a minimum the equipment must comply with the Low Voltage Directive and be CE marked. I also believe that manufacturers have to issue a Declaration of Conformity. 


BS 7671 722 has numerous references to the various standards required such as BS EN 61851 that the equipment must comply with. I am thinking it may be illegal to offer the sale of equipment that does not comply with the Low Voltage Directive and is not CE marked?


I am hoping the countries top man of equipment safety standards, Paul Skyrme , sees this post and will come on and give us his expert view?


Has any forum member asked for a Declaration of Conformity from EV charging equipment manufacturers and received one?

    Plugs and sockets are for some strange reason excluded from the LVD. 




    There is no Europe wide market for them as the are a UK centric device, and the other countries that have adopted them have adopted our standards requirements for them along side that.

    So if you have a nice shiny new M’plug EV charging station attached to the wall of the house just make sure that the electrician that installed it also installed a 30 mA double pole type A RCD in the consumer unit or circuit upstream of it, because apparently that single pole type AC RCBO is not fit for purpose.


    Helpful guidance from the manufacturer?


    Being single pole it doesn’t even count as an emergency switch and there’s no discrimination with the RCD that is required upfront of it, it fails to pass inspection on any points at all.


    It’s going to take twenty five minutes to write the observations up on an EICR.

    The data sheet / installation instructions from MasterPlug effectively say a Type A RCD (at least) is required upstream ! So they do tell you to do this.



    If conducting inspection and testing, EV CoP 4th Edition is now available, moved on a lot since 2nd Ed.

    I have been searching the internet and have checked the manufacturers website  without finding the data sheet or installation instructions, which brings us right back around to the original post.

    The EV charging socket has to be protected by a Type B RCD or a Type A or F with an direct current detection (RDC -DD). You cannot use a Type A RCD without the extra DC detection,it has to be Type B as a stand alone RCD.


    Thanks to Paul and Graham for pointing out that our fine British 13A sockets do not need to comply with the LVD as they are not used in Euroland.

    When does a general purpose 13-amp socket outlet become a charging point?

    When you plug an electric vehicle in!

    I was thinking at the very least, as soon as you install a socket labelled “Suitable for electric vehicle charging”.


    What about the pitch sockets on a caravan and camping site? Are all the sockets potentially a EV charging socket in such locations?

    On a caravan site the sockets are probably going to be connected to a TT supply usually but may be TN-S so no worries about loss of PEN. 16A or 32A sockets but doubt full RCDs do not meet 722. So not suitable for vehicle charging.

    You weren’t on the ball, you should have pointed out that the reference to use is BS7671:2018:Amd 1 2020 available to view on the IET website.
