I picked up my car at the factory on Saturday and had the electrician come over to install my NEMA 14-50 outlet bright and early this morning. After about an hour, he was finished and the install looked nice an clean. I wrote him a check, he went on his way, and I quickly plugged the charger in. I figured I would add a few miles of range before it was time to head off to work since the 120 V 12A overnight charge wasn't able to completely replace the charge used up by the weekend joyriding. As I was getting ready to go to work, I smelled something that smelled like burning plastic. I went over to the breaker box where the new breaker for the 14-50 was installed and I noticed some thin wisps of smoke coming out around the new breaker!:scared:
I yanked the charge cord out of the wall, shut off the breaker and quickly called the electrician back. He was properly concerned and raced back to investigate. Both the new breaker and the adjacent existing breaker had obvious burn marks. He drove back to the shop, got two new breakers, cleaned the bus bar, replaced both breakers, and then I plugged the charger back in and he waited there about 10 minutes to make sure everything was OK. After giving me the all clear, he went on his way again and I went to work. When I got home, I plugged back in and the car is now happily charging with no further incidents.
I'm still not sure if the new breaker was defective or just the act of messing around with the original 1954 electrical system in our house caused something else to fail. If you already have your car when you get your plug installed, I would strongly suggest having the electrician hang around for five or ten minutes while it's charging just to make sure nothing is out of the ordinary. If you get your plug installed before you get your car, you might want to hang around for a few minutes the first time you charge it. It would be a real shame to burn down your house- and your brand new Model S!
