commercial electrical load calculation worksheet pdf

The wattage is calculated by multiplying voltage times the power factor of the circuit.Įxample: Watts = Voltage times the Amperage times the Power Factor. VA is a standard measurement of electrical power that is used for identifying electrical circuit component requirements.Įxample: a 120 volt circuit which is providing 1 ampere = 120 volt-amperes.Ī watt is a measure of true power which is required to perform work at the rate of 1 joule per second. VA is the abbreviation for volt-ampere, which is a unit of power that is determined by multiplying the voltage and the amperage current in a circuit. The Basics of How Electrical Power is Measured and Calculated The Calculate Button Must Be Pressed when any changes are made to the form.
