Table 430-148 (From 1999 NEC)
Full-Load Currents in Amperes, Single-Phase
Alternating-Current Motors
The following values of full-load currents are for motors
running at usual speeds and motors with normal torque characteristics. Motors
built for especially low speeds or high torques may have higher full-load
currents, and multi-speed motors will have full-load current varying with speed,
in which case the nameplate current ratings shall be used.
The voltages listed are rated motor voltages. The currents
listed shall be permitted for system voltage ranges of 110 to 120 and 220 to 240
volts.
