The answer
Requires a dedicated 240V branch circuit sized at 125% continuous load per NEC 625 (48A charger needs 60A breaker and #6 AWG copper; 40A charger needs 50A breaker). Hardwired is standard above 40A; plug-in 14-50 receptacles require GFCI breaker in garages (NEC 210.8). Must pass panel load calculation and municipal permit inspection.
