I have NEMA14-50 in my garage, and would like to install Wall Connector using the same line.
Currently a subpanel has a 50amps circuit breaker for this line --
This subpanel is fed from the main panel, and has 60amps circuit breaker --
Subpanel has a few other circuit breakers as you can see on the first photo, not just the charger:
- kitchen outlets (x 3)
- bath outlet
- washer
- dish washer
- garbage disposal.
So it's roughly 10amps left to all of the above (with 50 amps for the circuit breaker).
Question: what circuit breakers I should use if I upgrade NEMA14-50 to a Wall Connector?
I think it should be:
- main panel's circuit breakers 60 amps -> 70amps for the subpanel;
- subpanel's circuit breakers for the EV charger 50 amps -> 60 amps.
The main panel's main circuit breaker is 200amps, and I think it's sufficient for the combined load.
PS. Extra karma question -- are there any limitations on the length of a line that's feeding into the Wall Connector?
My previous EV was a Leaf (charging on the front), vs Tesla has charging port on the back, so I have to park backing into the garage,
to reach the back of the car, or I am thinking to put the Wall Connector on the other wall so probably need to use bigger gauge
wires to maintain some resistance, but could not find any guidance on this.
PPS. I am planning on installing the Wall Connector myself, like I did the NEMA14-50 and the line that went from the subpanel to garage.
Thanks for any info!
