I'm getting my I4 M50 in a few weeks (at port in germany shipping to NJ USA) and its my first electric car. I want a level 2 charger for my house but im not sure about the best setup(purchasinga Charge Point). My goal is the highest amps for quickest charge. My question is how many amps should i tell my electrician i need? Whats recommended for the car? Not sure if im asking that question the right way or not. I know it depends on the panel but lets assume i have one that can support the highest power levels.
