Preparing for my first EV, Tesla. What would be the pros and cons of getting a 200amp subpanel to my garage as opposed to 100amp? I do plan to get a HPWC installed on the inside of garage. For future proofing, If I end up with two EV years later, would it be unwise to have another HPWC on the outside? Does extreme heat have any affect on the cables during charging?
