How Many Amps Is 9,600 Watts?

Answer
80.0 A at 120 V · 40.0 A at 240 V

Amps = watts ÷ volts. A 9,600 W resistive load draws 80.0 A at 120 V and 40.0 A at 240 V. That is too much for a 120 V circuit, so loads this size run on 240 V.

    Frequently asked questions

    Can a 15 amp circuit handle 9,600 watts?

    No. A 15 A circuit at 120 V supplies at most 1,800 W. Use a 20 A circuit (up to 2,400 W) or a 240 V circuit.

    How many amps is 9,600 watts at 12 volts?

    800 A at 12 V DC, before inverter losses (about 889 A through a 90% efficient inverter).
