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?

    Yes Simon, it matters to me. I take your point about just installing a socket and I agree up to a point, The charger is not the only appliance I can foresee being plugged in there, vacuum, pressure washer etc.

    But I know that the primary use will be to plug in the car overnight. I don't know the characteristics of the RCD in the charging lead, therefore don't know whether the upstream RCD I install will be blinded by any DC leakage currents. 722.1 Scope says "..circuits intended to supply electric vehicles for charging purposes", it will be a new circuit.

    Andy B, exactly. The socket should be labelled "EV" and "suitable for electric vehicle charging", 722.55.101.0.201.1 (i) so with such a label the client could feel inclined to invite friends with other vehicles and charging leads to use it. 


    Edit; I know I could take it out of the scope of 722 by spurring off an existing ring circuit, but that does not feel right to me.
