EV Charger

Well I'm confused now then. Note ii specifically refers to the earth rod being connected to earthing bar in the EVCP. In the event of PEN break there would be potential between the car and any extraneous conductive parts (unless the Ra meets the requirements of note ii).

Another thing to consider is proximity of exposed metal work earthed by the house supply in relation to the chargepoint such as water and gas etc. That meter cabinet could indicate a few services in the ground nearby so go careful banging the rods in!
Whilst the socket below isn't metallic the items plugged in could be class 1 devices.
Whilst unlikely you then have possibility of different potentials in fault conditions or when car is charging and something plugged.

Out of interest where abouts are you? I am in east England and as long as I can get a 1meter rod into good old Essex clay the readings are always around the 20ohm scale

That’s exactly what I was going to say especially about the socket below
I think I would just fit a pen relay as standard, too many potential problems with using rods
Or chargers that allow pme supplies

They will all have to eventually, it’s just too problematic otherwise

Did you only tt the charger or the whole property?

I'm in North Wales, this particular installation is in Rhos on Sea, North Wales. The TT system is only protecting the car charger ?

I should imagine it’s very rocky ground similiar to Cornwall unfortunately not good for rodding

In future I would probably insist on using pme friendly chargers maybe? Save you the headache!

Nice tidy looking install tho ?

Thanks mate! Yess I will use PME friendly chargers next time, like zappi?? This specific install, it was for someone I know and they had supplied the charger. I know for next time! ?
