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?

    Hence the preference for a dedicated EV charging circuit, even if it is only a 13-amp socket?





    But BS 7671's idea of a circuit considers only overcurrent protective devices, not RCDs - so you could have a separate circuit for the EV point but still have the upstream RCD shared with other circuits (e.g. as in split load CUs).


    Yes but ...

    722.531.2.101 "... each charging point shall be protected by its own RCD ..."


    If the circuit is in say a garage, it might be clipped direct, in trunking, or in conduit, so no need for the RCD to be in the CU. If the EVCP is on the side of a house and the cable is buried in plaster, it will need an upstream RCD. If that is not an RCBO, there will have to be another one locally.


     




    Yes but Andy does have a point ... in A1:2020 to BS 7671:2018,, this Regulation has been revised, now numbered 722.531.3.101 and the point need not have its own RCD.  And in the same amendment, the charging point must have its own overcurrent protective device (722.533.101).
