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?

    The separation distances that "keep cropping up" in the case of separation of TT systems (2.5 m, 3.5 m, 10 m) are actually based on Figure 16 in BS 7430.




    Graham, thank you for your opinion above. So I think that I would be all right 'cos the service cable is modern and the old PILC one is a good 10 m away where it runs in company with the probably metal gas pipe and probably plastic water pipe. The gas main in the street is still metal and runs very close to the lamp post and the JB to my property.


    I know all of this 'cos being a nosey sort of character, I was present when holes were dug.


    But what I don't know is what goes on next door, so yes I can see that TT doesn't work for everybody.
