I went to a job today for a long standing customer of ours who had an unrelated problem.
While I was there customer asked me to look at the above charger that had been fitted in their car port. Whoever installed it - possibly Chargemasters in house team did a few things that were either clearly wrong or some that didn't seem right to me. I don't have any experience with fitting EV chargers.
It was apparently fitted in June on the recommendation of BMW. Customer mentioned the guy had to come back and "change something in the consumer unit" at the house. The car port is around 30m away. That set alarm bells ringing for me and I also didn't see a rod so I thought I'd have look.
Supply to car port in 4mm XLPE and part 4mm T&E. 32A RCBO sitting on top of consumer unit. It had been swapped for a 40A RCBO. Think we all know 4mm T&E is not rated to 40A. Charger rating plate says 30A. Guess it had been tripping the 32A RCBO so he swapped it out. The car port also has a few lights/general use sockets.
The earthing system is PME. No earth rod - they had used the exported earth for the EV charger. I'm pretty sure thats now a definite no in 18th? However I'm not sure where you would stand under 17th regs? I've come across quite a few, probably 10-15 EV charging points at peoples houses in the past year or so. I'm yet to see an earth rod!
