NEC 440: motor-compressor circuits. 440.4 nameplate data required: rated-load current (RLA), locked-rotor current (LRA), branch-circuit selection current (BCSC). Conductor sizing: 440.32 per BCSC (not RLA). Overcurrent protection: 440.22 max 175% of RLA for HACR breaker (or per nameplate MCA — minimum circuit ampacity). Disconnect: 440.14 within sight of equipment, rated for locked-rotor current (or HACR rated). Short-circuit protection: per nameplate MOCP (maximum overcurrent protection). Multi-motor equipment: treat as single motor-compressor per nameplate. Common: outdoor condensing unit nameplate says MCA=25A, MOCP=40A → use 10 AWG conductors, 40A breaker.
