The ElectriCalc Pro can calculate the Full-Load Current (Amps) of a 

motor, based on Phase, Voltage and Motor (Synchronous, Induction, 

or DC) Horsepower. It uses NEC Tables 430.247, 430.248 and 

430.250 to determine the motor Full-Load current. (If you enter a 

value for HP or Voltage that does not correspond to these tables, the 

unit will display 

none).

The ElectriCalc Pro can also calculate an equivalent Horsepower 

for an Induction, Synchronous or Direct Current motor based on a 

Voltage, Phase and Full-Load Current. When calculating Motor HP 

from an entered Amperage, a result not directly matching a value in 

NEC Table 430.247, 430.248 or 430.250 will cause the calculator to 

choose the next higher table value for Motor Horsepower.
