(see also: Quick estimates for thermal wattage requirements) In this first part we focus on the wattage required for process start-up.
Get A QuoteFor a single phase AC circuit the formula to convert kilowatts (kW) to amps is: amps = (kW × 1,000) ÷ volts. It is possible to find the amperage from kilowatts if you know the voltage of the circuit using Watt's law. Watt's Law states that current = power ÷ voltage. In Watt's Law, power is measured in watts and voltage is measured in
