The NEC is basically the fire code for building wiring.
It's not a general safety code.

- amluto 6y agoIf you look at the actual construction of a Supercharger station [0], the charger stall units don’t have any power electronics. There is a pair of big DC wires from each stall unit running to the big AC-DC units that are usually behind a fence. Regardless of how anyone may feel about the NEC, this is a field installation that needs to follow the rules. So those big cables will be sized per the NEC ampacity tables, and they will follow NEC rules based on their operating voltage. [0] I randomly stumbled on one under construction.
