SATTV:[snip]( I would be running 6mm cable to allow for electric car charging in the future )
I would think that 6mm would be minimum if planning for an EV circuit. Your sparky should be able to advise though, given the cable length etc.
My stovetop has 6mm cable and draws 32A so should be fine, realistically you dont need to charge a car from a 32A socket, a 10A is fine, takes longer I know, most prople would plug their car in when they get home and unplug when going to work. Having 32A allows you to have two cars, a couple of e bikes, beer fridge, Chest freezer and a couple of servers running without an issue.
