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?

    Regards taking a peek inside any socket back box you, particularly an outdoor socket of any kind you work through the mental check list:
    • Does it look like a tidy installation.

    • How long has it been installed.

    • Is the enclosure intact, including the lid or has the IP ratings been compromised.

    • Does the socket have signs of thermal damage or is it cracked,

    • Testing without disassembly, R1+R2 or R2, insulation, polarity, single pole protective devices in the live phase, earth loop impedance and RCD times.

    • Whatever I have forgotten to write down, but would just check by habit on the day.


    We should know a lot about the socket before we decide to start digging out the sealing caps over the screws holding the enclosure together to take a peek inside the back box and we should know about any specific issues we are looking for, there may be a surprise awaiting the inspector inside the back box, but most times you know there’s an issue before you open it up.


    Assuming this EV charging socket is on its own circuit what are we looking at time wise to check the socket and circuit, twenty five minutes? So there probably is time to take it apart as you are supposed to take some fittings apart during the inspection.
