TL;DR
A charging amperage setting is the maximum current an EV charging station is configured to deliver, selected with DIP switches or a smartphone app so the unit matches the circuit feeding it. Because EV charging is a continuous load, the NEC limits the charger to 80 percent of its breaker rating: a 60-amp circuit supports a 48-amp setting, a 50-amp circuit supports 40 amps.

Because EV charging is a continuous load, the NEC limits the charger to 80 percent of its breaker rating: a 60-amp circuit supports a 48-amp setting, a 50-amp circuit supports 40 amps. Installers record the value at commissioning, and inspectors may check it against the breaker and wire gauge.
