Hi there, I'm a noob here with the recent addition of a Model Y to the family. Wife love the car and is having fun learning the vehicle.
I'm about ready to have an electrician come out to install our Tesla Wall Charger. We will be running wire from the garage panel within the walls to a spot on the wall about 15 feet away (total line run). I know the typical install for this is 6GA wire but I am looking to future proof the install so that it can support increased amperage in the future. My assumption is that battery capacity and charging speeds are only going to increase, so want to overbuild it now to accommodate for the future. I can see where 48A (on a 60A circuit) will increase to 64A (on a 80A circuit) and further increase to 80A (on a 100A circuit).
I'm not an electrician as you can see but would appreciate the thoughts and guidance from folks that have faced this decision.
If I understand correctly:
4GA can support up to 70A (at 140 degrees F)
3GA can support up to 85A (at 140 degrees F)
2GA can support up to 95A (at 140 degrees F)
So it would seem that I should be looking at 4GA minimum and preferably 3GA or 2GA to support up to a 100A circuit.
I'm sure there is a lot more to it but would appreciate your opinions! Thanks in advance!
