I am having an electrician wire my nema 14-50 plug tomorrow. I read that some people have it connected to a 50amp circuit breaker and some to a 60amp circuit breaker. Does anyone know which is better? I am planning on using the home charging plug that came with the etron.
Thanks

The circuit breaker size will be based on the wire size used from the panel to the 14-50. To use a 60A circuit breaker, you will need to run 6 gauge wire, but for 50A you can run 8 gauge (cheaper).
50A vs 60A will not affect your charging speed, assuming both go through a 14-50 plug.

I wired my own garage circuit for the ETron level 2, and frankly, a 60A circuit will cost you more for the wire and breaker, but gain you nothing.

Ok great! The guy installing it usually does Tesla chargers so I just wanted to make sure I was getting the best charging performance I could out of the garage. Thanks

Depending on your voltage at the charger outlet (208-240), the amperage required to deliver 9.6kWh is between 38-44.25A. Your breaker should have a limit 20% higher than your expected load. We have a 50A and it works fine. Per Joe's post, the bigger wiring to bear the 60A will probably cost a pretty decent chunk of cash. To date, the only charger that is bigger is a clipper creek unit which will run at around 65A. (They do have an industrial 80A but it costs $2700...)...

If you are using the Audi module, 50A should do it...

I have a 40A dual pole breaker with no issues. I had a 50A breaker but electrician downsized based on the rating for Audi charger. FYI...
