Hi everyone! I will be getting a Model 3 soon and now need to install an outlet for charging. My breaker box outside is on the opposite side of the house in relation to the garage so not possible to pull a line in from the outside. I have gotten a few quotes/opinions from electricians but have received somewhat differing opinions. The breaker outside that feeds the subpanel is rated 60 amps. I have two empty slots on the panel where every electrician says they can use both to pull 240v/30amps and terminating it in a new outlet. I had one electrician saying that he must upgrade the breaker to something more than 60 amps before he would proceed. The other 3 electricians say that it is not required and that I would most likely need to upgrade the wiring between the breaker and the subpanel first anyway if I really wanted to do that. I've attached pics here and hope to get a knowledgeable opinion to move forward! Do you guys think I would be fine to leave the 60 amp breaker as is and moving forward with creating a 30 amp line out of the subpanel? THANKS!
