Locked rotor code letter: PE Power Rotating Machines practice question

A 100 hp, 460 V, three-phase, 60 Hz induction motor with a nameplate speed of 1,780 rpm drives a process air compressor. Its nameplate shows locked-rotor code letter G, which NEC Table 430.7(B) and NEMA MG 1 define as 5.6 up to (but not including) 6.3 kVA per horsepower.

To check the voltage dip when the motor starts across the line at rated voltage, the engineer needs the largest locked-rotor current the code letter allows. That current is most nearly:
