Nice job. However that breaker in the main panel that feeds the sub panel looks like a Siemens. It should be a GE to match the brand of the main panel. That is important especially now since a lot of current will be running through it to charge the car.
I have a question. I have the 10-30 dryer outlet on my garage wall, and I am only using the gas dryer. I bought the new Gen 2 NEMA 10-30 Adapters from Tesla. Every time when I charge my 2021 Model 3, the first few minutes can get 25mi/ hr , 24/24V 236v , but after 5-10 mins, it changes to 12mi/hr 12/12A 236V automatically . And never go back to 25mi/ hr , 24/24V 236v again. Do you know what is going on ? I hope you can help me.
