What’s the maximum length of 3 pin plug cable you could use to charge a PHEV, ours would need to be about 10metres to reach the outside of the house. What length of cable is supplied with your PHEVs?
I have made up our own extension cable using 2.5mm 3 core orange caravan cable ( be careful some on eBay are only cheap 1.5mm) and fitted a 3 pin waterproof socket.
Unfortunately I have suffered a brain injury and occasionally I get confused and often say the wrong thing.
