Is 8m the longest?
Our situation is that the driveway is at the end of the rear garden (about 17m) and when I had a survey done for a charge point for my works vehicle they said they have to dig a trench through the garden. Everything else was okay, but the landlord wasn’t keen on this.
I know you can get cables up to 20m, but the need fitting by a spark. Is there any easier way of extending or getting MB to fit a longer cable?
