With those level 2 hard wired Tesla Chargers I always recommend a 60 amp breaker(125%) and getting a 200-amp service. ( because most customers still may want to charge during the day which can overload that 125-amp main breaker. Overhead replacement will be less expensive than Underground.
You mentioned 50 amp breaker for the hardwire charging unit but those are good for 48 amps, so wouldn’t it need 60 amp breaker since it’s continuous load?
The breaker and wire both have to derated to 80% or oversized to 125% of the continuous load (same result). How the wire is run (metal conduit with thhn/xhhw-2 vs nm-b/ser/seu/pvc conduit) can also determine the wire size due to thermal limitations.
I've always thought the charger sweet spot is 240V at 30A (24A actual). It can use common, cheap 10-2/10-3 NM, and it leaves enough headroom on a 200A service to add another charger in the future. That gets you somewhere around 22-24 miles per hour of charging, which for your garage, is plenty considering most people drive less than 50 miles a day and you have overnight. All the 50/60A hookups do is cost more money for bragging rights, and they limit a future 2 car setup unless you drop it down and under-use the wire.
Wow! GOOD STUFF in entirety. So you put a 90A breaker in the main for a 100A subpanel while there is a 50A breaker for a basement subpanel? I also see a 2P30A in there. Wondering if you looked at the amp draw. I would love a video on that!
It makes me feel uneasy when you slap the breakers that have some bare terminals and bus bars at 05:47 . I understand that the breaker panels must be disconnected, but still... and your gloves don't look like insulating ones. If this becomes a habit, it will hardly be a good one. 💤

Tesla uses the ground.. it doesn't need the extra neutral wire for 120.
