I will be installing the Home wall connector soon in anticipation of my Model X WITHOUT the High Amperage Charging Upgrade. I know I'm only required to have a 60Amp Circuit Breaker but my question is other than possibly increased installation cost, Is there any reason I shouldn't opt for a 90Amp Circuit Breaker to future proof my installation in case I upgrade later? Maybe a dumb question I'm just not sure if the increased power will have an adverse effect when charging the car or if it will regulate it's self to what the car can handle. I'm fairly confident it won't be an issue but I'd rather ask then find out after I installed. THANKS.
