I have the electrician installing the NEMA 14-50 with 40 amp service/50 amp breaker in the coming weeks. My thinking is...just in case at some point in the future I want to add the dual charger and wall connector I would have him use the larger wire and conduit to satisfy 80 amp service/100 amp breaker. The run is short so the difference in cost is negligible. Question becomes does it make sense for me to go ahead and get the wall connector and have it installed even if the dual charger is not. Best I can tell it will still provide the 40 amp service it would just be permanent on the wall and then keep the other connector that comes with the car in the car. Thoughts?
