You’re good and on the right track. I would just add that you’re not installing a ‘charger’ per se, but a fancy cable hanger.

The dip switches (good) are only there to communicate to the car (where the charger is located) how much current the car is allowed to draw. This so car [charger] does not draw more current than what the [house] infrastructure can support.

Level 2 ‘chargers’ are only a way to safely deliver 208/240 V AC to the car. People get overly hung on this [charger] and often spend far more than what they need. Or are a bit deceived of what the devices actually are and do.

But with a high static load (or high continuous load), it is imperative that all connections are properly done, are tight, as you will be pulling a decently high amperage for extended periods of time, and not like a clothes dryer (a comparable load) that often runs less than an hour, with load switching on and off during the time. A poor connection can easily overheat, leading to further heating. Etc.
