I just got a quote for how much it would be to get a 220V plug in my garage, $8K! Sure I'm buying a nice car, but I did not think it would be so expensive to get the garage ready to charge a Model Y.
  1. Install Nema 14-50 (located on the left side inside the garage) on dedicated 240V-40amp from your Main Panel with 70LF Romex Cable 6-3 copper plus 30LF wire in pvc conduit 18 inches below ground. Cost: $3,000
  2. Trenching: $5,000
My garage is detached and basically on the other side of a 5,000sq/ft lot from the main electrical panel. The trenching assumes it's concrete all the way, but it's not (mostly just dirt/grass), so that might be a lot more than it would cost. But still, this is crazy.

The garage subpanel doesn't really show much, but it seems like there isn't a dedicated wire to it that can do 220V for the Nema 14-50.

Maybe this is just how much it'll cost? Any ideas? Or I can just use the regular outlet and have the slowest charging ever.

The capacity of my main electrical panel: Main Panel 240v-125amp (Brand: Eaton).
