Install A Dedicated AC Line at home

Most sparky's will just want to argue with you and tell you why you don't need to do this and if you insist they'll say your crazy and anyone that says you need to this is just plain nuts! I would Study enough electrical handbooks and diy. It isn't rocket science and can be most enjoyable. You'll want to run two or more home runs to your room. 

This is a @jea48 , question.

I installed my own dedicated line and I defy you to tell me which line I did and which was the original wiring. It’s really just a mechanical process as long as you turn off the main breaker. One suggestion is to pull your own wire if you can and then have the electrician wire it into the panel. Pulling wire is pure grunt work. Use existing holes in your floor joists if you can and if that’s how your home is constructed. 

Berkeley local here, 

  Give Din at Electrical Installations a call. He’s a electrical contractor  in Oakland, licensed, and bonded. Worked with him a bunch, he knows his stuff. Just tell him you want a dedicated circuit, he’ll do the rest. 

Find someone who can do it for cash on the side. You live in CA. If you go by the book you will need to pull permit, have three inspections, and an environment impact study done before any work. You will be in at 5K before they touch any wire. Might want to have the file for permit claiming it is a plug in station for your electric car then the state and city will pay for it snd also give you a tax break. I don’t and never ever will buy an electric car but put in charger as it was free and a 6K tax credit! Nothing better than beating libs at their own game!
