We just placed our order for our first Tesla and we have inquired with a local electric company for converting 2 standard outlets to a 14/50 outlet. The estimate came back at $600 ($200 for material and $400 for labor). From all of the video's I've seen, that seems high. The panel is next to our 2 car garage and inside our house. The wires are run through the attic and accessible. What are other people paying for the conversion?
