If an engineer is specifying a 50 HP, 460V, 1800 RPM motor, they will consult the NEMA MG1 data (reflected in Table 33) to determine the full-load current is approximately 65 Amperes . This "AMP-33" figure is then used to size the upstream breaker (typically 125% of FLA for continuous duty) and the conductor wire gauge. 1800 RPM motor
