Hello. I’m new to EV vehicles and getting ready to receive my model 3 in a few days. I currently running a 200 amp main breaker with a 100amp break running to the sub panel. The sub panel is at a detached garage, so really doesn’t get used much. I see that o have 3 30 amp breakers but really I think I only use 1 to power a A/C unit. I’m wondering if a 50 amp breaker will be fine to install on the sub panel.
