If you electrician has the proper Part P certifications for fitting home chargepoints they will figure out what to do, if they don't then you should pay for someone that has proved themselves competent.Thanks, informative video. I would have liked to see the wiring into the consumer unit as that’s what I’m really interested in, but I gather this is his umpteenth charger and the wiring is already in. Still, I’m a bit clearer about what I need and the wall unit looks great.
It will typically be a simple 32A MCB in the Consumer Unit* but the installer also should run a data cable back to connect a CT clamp (the right way round) to the feed from your meter and programme the Hypervolt to monitor total current. Jordan from above likes to use a special type of armored cable called EV Ultra that includes the data cable in the same wire.
* don't believe electrical safety advise you read on the internet.
