TL;DR
An EV dedicated branch circuit is a circuit serving nothing but vehicle charging equipment, run from its own breaker and sized so the charger's continuous draw does not exceed 80 percent of the rating — a 48-amp charger therefore needs a 60-amp circuit in 6 AWG copper. The NEC treats EV charging as a continuous load, and most hardwired Level 2 installs also require GFCI protection or rely on the unit's internal protection per its listing.
