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?

    Manufacturers installation instructions can be rather scant when it comes to how to connect the electrical supply to an EV charger, this description of how to wire an EV charger is from a forty page installation manual, three paragraphs from the whole document. There certainly is not any discussion about using open PEN detectors or the actual requirements for earth rods.


    Supply

    The zappi device should be connected to a single-phase 230V or 240V nominal AC supply. The supply should be from a dedicated 32A or 40A circuit breaker.

    Earthing

    The unit must be earthed in accordance with local regulations, e.g. It may be a requirement to install an Earthing rod if the supply is PME.

    Cable Entry

    There is a grommet in the rear of the unit for through-wall cable installation. If however, the supply and/or sensors cables are surfaced mounted, there is space at the bottom right-side of the enclosure to drill holes for the cables. It is essential that correctly sized cable glands with a minimum IP65 rating are used.
