I had a few basic questions which I ended up resolving myself for a DIY install. However, just to be certain I called the helpline for charger installs. I basically got a receptionist who had no knowledge of electricity other than anything thats listed on the Tesla website. She put me on hold to "check with an electrician they had" and then gave me a generic response out of the Wall Connector manual. Maybe it was a one-off thing, but they are certainly better off NOT offering this at all.
