Per 430.22, motor branch-circuit conductors for a single continuous-duty motor must generally be sized at not less than what percentage of the motor's full-load current?
Not quite. The answer is C: 125%
430.22 sets the baseline at 125% of the motor's full-load current (taken from the Article 430 tables) for the branch-circuit conductors of a single continuous-duty motor. This is a motor-specific rule that happens to match the 125% used for continuous loads elsewhere.
Reference: NEC 2023 430.22 (Motor Branch-Circuit Conductor Sizing)
Checked against multiple published sources
Three sources agree on 125% of full-load current: an ECM quiz based on the 2023 NEC, an ECM guide, and a Mike Holt motor chart citing 430.22. None is the code text.
