Frequently Asked Questions
Divide watts by voltage: Amps = Watts ÷ Volts. E.g., 1200W ÷ 120V = 10A.
1000W ÷ 120V = 8.33 amps.
1000W ÷ 240V = 4.17 amps.
Watts = power; Amps = current. Voltage links them: W = A × V.
Same wattage draws different amps at different voltages. Higher voltage = fewer amps.
