A Level 2 EVSE has a maximum continuous current of 80 A. Applying the 125% continuous-load factor from 625.41, what minimum branch-circuit rating is required?
Not quite. The answer is C: 100 A
80 A × 1.25 = 100 A minimum branch-circuit rating — this is exactly why an 80 A Level 2 EVSE is routinely paired with a 100 A dedicated circuit in the field. Sizing the circuit at the EVSE's nameplate current alone, without the continuous-load multiplier, would leave the installation undersized and out of compliance.

Checked against multiple published sources
A Mike Holt 2023 NEC changes text places the 125 percent EVSE overcurrent rule at 625.41 (its worked example is 40 A x 125% = 50 A); an ECM article groups it under 625.40-625.41 without naming an edition. Neither is the code text.
