FORMULAS FOR CALCULATING AMPERES

	horsepower times 746, divided by the voltage, will give you amperage
	wattage divided by voltage will give you amperage
	kw times 1000, divided by the voltage, will give you amperage
	kva times 1000, divided by the voltage, will give you amperage

Three Phase

Three phase calculations can be done by multiplying
the voltage by 1.73 (as seen in the example below)
Each of the single phase formulas will work this way
by multiplying the voltage by 1.73

horsepower times 746, divided by voltage times 1.73, will give you amperage
