NON COMPLIANT NEW EV INSTALLATIONS

John Peckham
I was sent some information from the ECA concerning an audit undertaken by the Office of Low Emission Vehicles.


The sites inspected were those installed by "qualified" and "registered" installers claiming the OLEV subsidy.


0.8% were found to be dangerous (C1), 19.6% Potentially Dangerous (C2) and 25.6% requires improvement (C3). That makes 46% of new EV installations by qualified and registered persons to be non-compliant.


Am I the only person who thinks this is an utter disgrace?

    A couple of issues with your posts.


    1. Harry you do not need a concurrent earth fault on a vehicle charge point with the loss of the supply neutral. With a loss of the supply neutral the vehicles bodywork will rise up  to a voltage possibly approaching 400V. A person grasping the door handle or a child reaching under the vehicle to retrieve a ball could receive a fatal shock.


    2. UKPN the agreed procedure with the ENA/DNOs is if the EV extra load does not exceed 13.8kW MD then the installer must inform the ENA within 1 month. The ENA has an on line facility to do this. They then inform the DNO. If the MD will exceed 13.8kW then the installer must inform the DNO before work commences for consent. You will of course know that as UKPN is a member of the ENA?


    3. I know that the IET has done a lot of research on this subject and has involved a lot of input from industry experts including the HSE and ENA so glib remarks about the the IET are at best ill informed. I was involved with giving presentations on this subject with the IET at Elex shows. We did 2 at Ali Palli and Manchester before the lock down. I have posted on the forum about the free Webinars coming soon, you may find it useful to watch the first one as the topic of MD and EV are covered by the counties leading expert on the subject.


    4. I used to think I knew it all when I was a highly trained Technical Officer in the Post Office now I realise how little I know and every day is a school day!
