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 3,500 watts?
Frequently asked questions
29.2 amps (3,500 W ÷ 120 V). On a circuit, a 3,500 W resistive load needs at least a 30 A breaker — and 25% more if it runs 3+ hours continuously.
