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?

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

    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.

    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.

    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.

    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.

    The 1 port 2.3 kW mode 2 uk 3 pin plug electric vehicle charging station is not a complicated bit of equipment.


    Indeed it is an IP rated outdoor double accessory box with a single socket in one side and a single pole C16 RCBO providing Type AC RCD and overload protection in the other side.


    Straight away this raises some potential questions, so like JP some people thought they would ask the manufacturer for guidance, some of them did this through the S’fix website, so we can see their question and the answer from the manufacturer.

    For example:

    I thought that anything to do with EV Charging required a Type A RCD or RCBO




    This does not comply with current EV Charging BS 7671 Wiring Regulations

    Hi BoomSparky,

    The current regulations do require that there be at least a Type A device `at some point from the distribution board to the outlet' protecting an EV charging installation, it does _not_ specify that this needs to be immediately at the socket.

    So let’s just refer to the Code of Practice (mine is the second edition):

    But, at least "standard" plugs and socket-outlets are covered by the Plugs and Sockets (Safety) Regulations 1994.

    ...

    But we are getting away from JP's OP. ..




     



    Apologies John. 

     


     




    Ah! But! I am trying to steer it back around.


    Does anyone have one of those Masterplug 13-amp EV charging stations to hand or fixed to the front wall of their house or somewhere similar? If so please go and dismantle it and post a picture of where the socket is marked EV on its rear.


    If if I see one of these whilst undertaking the preparation of an EICR I will definitely be taking it apart to have a look inside it.
