Be Careful With Your EV Wiring Done.
Many installers these days find ways to use cheap or thin wires and you wouldn't even know about it. They replace the neutral or earthing 1 of the 5 wires with a thin or different cheap brand, and thats what causes many issues later on.
When your wire used is 4mm or cheap brand, it can cause your whole db box to spoil causing many other expensive repairs.
