GENERAL INFORMATION
Typical Full Load Currents
For Single and Three Phase Electric Motors
The information in the chart below was obtained from the National
Electric Code Table 430-148 and 430-150 and from U.L. Industrial
Control Standard 508. The voltages shown are standard rated motor
voltages. The currents listed are permitted for system voltage ranges
of 110-120, 220-240, 440-480, and 550-600 volts.
The full load current values listed are for motors running at standard
speeds with normal torque characteristics. Motors which are
non-standard, such as low speed, high torque or other special
applications may have higher full load currents.
Caution: For accurate and reliable motor protection, motor nameplate
current should be used to obtain actual motor full load amps for all
motors.
