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?

    Just how safe are “granny leads”?



    To some extent they should be similar to a wall mounted mode 3 charge point - apart from the first few inches of lead (before the in-line box of tricks). The in-line box providing similar functionality to the gubbins inside a mode 3 charge point. PME earthing issues aside.

     

    What are the standards for “granny leads”?



    I'd hazard a guess at BS EN 61851-1 (but Graham probably knows better than me on that point),

     

    Can they and do they actually leak DC current, why don’t they have an inline RCD in their flex like some of the portable hot tubs?



    They do - an RCD of some sort in the lead (within the box of tricks - sorry "In-Cable Control and Protection Device (IC-CPD)") is a basic requirement. Exactly what kind of RCD seems less clear....
