I'm planning for the Tesla 14-50 outlet install very close to my panel. My panel is 100A and doesn't plan to upgrade anytime soon and hence ruling out a Tesla wall charger in the near future. I understand that 6-3 Copper is ideal, but have a spare 8-3 Copper wire and 6-3 Aluminum wire at my disposal for outlet install. Since the Gen 2 charger limits 32A, which of these would be better in terms of less heat and longer life?
