I'm starting to plan for getting a car charger installed.
The ideal location would be on the garage wall next to the drive.
The garage has a 4mm armoured cable from the main consumer unit currently fused at 32A.
The consumer unit is 35m away on the opposite side of the house.
Does the charger need to be connect to the main consumer unit, or could it use the garage supply?
(I think chargers are normally 7kW, so it would pretty much max out the 4mm cable).
If it could reuse the existing garage connection, would it desirable anyway to run a new cable? (thinking that over 35m on 7kW the voltage drop is likely to be material and it may be worth using an overrated cable to save on transmission losses).
Experiences welcomed.
