Brought home my MS last week. I have a 240 outlet on a 40 amp breaker in the garage from my failed Nissan Leaf experiment back in 2011. The outlet I had was the wrong plug configuration so I called my trusty sparky who has about 50 years of experience to come over and change the plug that I picked up at Home Depot for $8. He said I could pull 50 AMPS easily off my 40 AMP set up as the distance from the plug to the breaker box is so short (about 2 feet). He gave examples of using a 20 amp tool off a 15amp breaker- said it's done all the time etc. His question was how does the car know whether your set up is 40AMP or 50AMP? As I learned from this forum if I had a true 50AMP set up the car would charge slightly faster? Thanks!
