NOMINAL AMPERE RATINGS OF AC GENERATING UNITS ON SINGLE PHASE (100% POWER FACTOR approximate values)

NOMINAL AMPERE RATINGS OF AC GENERATING UNITS ON SINGLE PHASE (100% POWER FACTOR approximate values)				NOMINAL AMPERE RATINGS OF AC GENERATING UNITS ON 3 PHASE (80% POWER FACTOR approximate values)
TO FIGURE HOW MANY AMPS A CERTAIN KW UNIT WILL DELIVER USE THE CHART BELOW OR TAKE KW AND MULTIPLY BY 1000 THEN DIVIDE BY THE VOLTAGE YOU ARE GOING TO USE FORMULA IS KW * 1000 / NEEDED VOLTAGE = AMPERAGE AVAILABLE				TO FIGURE HOW MANY AMPS A CERTAIN UNIT WILL DELIVER ON 3 PHASE USE THE CHART BELOW OR TAKE KW AND MULTIPLY BY 1000 THEN DIVIDE THAT BY VOLTAGE MULTIPLIED BY 1.73 MULTIPLIED BY .8 FORMULA IS KW * 1000 / ((VOLTAGE * 1.73) *.8)
OTHER SCIENTIFIC FORMULAS YOU CAN USE FOR CALCULATIONS: WATTS= KW * 1000 POWER (WATTS) = VOLTS * AMPERES AMPERES = POWER (WATTS) / VOLTS VOLTS = POWER (WATTS) / AMPS (SINGLE PHASE) KW / .8 = KVA				TO FIGURE HOW MANY WATTS A DEVICE WILL USE IN A 3 PHASE APPLICATION, USING INPUT RATING, TAKE INPUT VOLTAGE X INPUT AMPERAGE X 1.732 X .80 THE CONSTANT 1.732 RESULTS FROM THE FACT THAT NOT ALL 3 PHASES ARE PRODUCING THE SAME AMOUNT OF POWER AT THE SAME TIME AS THE WAVES GO THRU ZERO AT DIFFERENT TIMES. FORMULA IS ((VOLTAGE * AMPERAGE) * 1.732 * .8) / 1000= KW
SINGLE PHASE COLUMNS (pick proper single phase voltage column 3 or 4, scroll down to needed amperage then follow that row left to KW, then take that KW*1.66= KW SIZE NEEDED)				THREE PHASE COLUMNS
