I expect delivery of my LRY early next year. I am looking at wiring options for the Tesla wall charger in the garage. My main incoming breaker is 200 amps, however I do not have space in the panel for a 60 amp breaker. I have 2 sub panels, both supplied via 60 amp breakers. One panel has the space to install additional breakers. My question is - can I change the sub panel breaker in the main panel to 90 amps (I have AL type se style r type xhhw 600 3 cdrs 2 awg cable servicing this panel) and then install a 60 amp breaker in the sub panel for the charger?
