MOTOR FUNCTIONS

The ElectriCalc Pro can calculate

the Full-Load Current (Amps) of a

motor, based on Phase, Voltage and

Motor (Synchronous, Induction, or

DC) Horsepower using NEC Tables

430.247, 430.248 and 430.250.

Finding Full-Load Current

A 2 HP Induction motor operates on

230 Volt, Single-Phase power. What is
