Motor Horsepower

The ElectriCalc Pro can calculate the
full load current (amps) of a motor,
based on phase, voltage and motor
(synchronous or induction). It uses
NEC Tables 430-148 and 430-150 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 Error 8).

The ElectriCalc Pro can also calculate
an equivalent horsepower for either an
induction or a synchronous 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
430-148 or 430-150 will cause the cal-
culator to choose the next higher table
value for motor horsepower.
