4.3) AMPERAGE CALCULATIONS
The
INPUT VOLTAGE, PHASE, TOTAL POWER RATING,
and
HEATER
VOLTAGE RATING
are used to calculate the amperage.
NOTE:
380-425V heaters are not usually rated for 380-425V. They are usually 208-240V heaters
that have been re-stamped 380-425V and wired in series.
FORMULAS TO CALCULATE AMPERAGE
