Motor Wire Sizing. It is required by the NEC for circuits supplying single motors to have an ampacity rating of greater than or equal to 125% of the full-load ampacity rating of the motor.
HP to Amps Conversion Chart: Below table is calculated amps value for the respective standard motor horsepower rating. The table first column indicates the DC current and followed by the AC current. AC current is calculated by the power factor of 0.86 for single-phase supply and 0.8 for three-phase supply. Look at the table the 1 hp motor takes ...
This calculator estimates the crucial full load amps (FLA) your motor will draw at its rated horsepower. Enter the motor’s voltage (line-to-line voltage between any two phases) and horsepower. For a more precise calculation, include the motor’s efficiency (typically 90-95%).
