kVA per Horsepower is Calculated as Follows:
For three-phase motors:
For single phase motors:
Table 10. NEMA Locked-Rotor Current Code Letters
➊
Locked-rotor kilovolt -amperes-per-horsepower range includes the lower figure up to, but not
including, the higher figure (i.e., 3.14 is letter “A” and 3.15 is letter “B”).
