PF = power factor. Resistive loads (heaters, incandescent lights) are PF 1.0; motors and compressors typically run PF 0.8-0.9. For a different value, use the interactive converter.
What draws about 1,500 watts?
Frequently asked questions
12.5 amps (1,500 W ÷ 120 V). On a circuit, a 1,500 W resistive load needs at least a 15 A breaker — and 25% more if it runs 3+ hours continuously.
