4.4) ACTUAL POWER RATING CALCULATIONS
Because the HEATER VOLTAGE RATINGS only come in 4 different voltages, and there
are so many different voltages in the field, the TOTAL POWER RATING is only completely
accurate if the VOLTAGE IN is exactly equal to the HEATER VOLTAGE RATING. This
means, in most cases, the TOTAL POWER RATING is not completely accurate. The
AMERAGE and INPUT VOLTAGE can be used to calculate the ACTUAL POWER
RATING.
FORMULAS TO CALCULATE ACTUAL POWER RATINGS
THREE PHASE SINGLE PHASE
DEFINITIONS: PA = Actual Power Rating
I = Amperage VI = Input Voltage

4.5) STEAM CAPACITY CALCULATIONS
Steam Capacity Calculations are based on the impossible feed water temperature of 212°F.
WARNING – Anything above 140°F will cause damage to water solenoid and pump.
