How Many Amps Is 17,040 Watts at 24V?

17,040 watts equals 710 amps at 24V on a DC circuit. On AC single-phase at PF 0.85 the same real power would be 835.29 amps.

Assumes a DC circuit. Typing a commercial L-L voltage (208/400/480V) re-routes the result to three-phase; 277V stays on single-phase because it's the L-N lighting leg of a 480Y/277V wye; 12/24V re-routes to DC.

Formulas

DC: Watts to Amps

I(A) = P(W) ÷ V(V)

17,040 ÷ 24 = 710 A

AC Single Phase (PF = 0.85)

I(A) = P(W) ÷ (PF × V(V))

17,040 ÷ (0.85 × 24) = 17,040 ÷ 20.4 = 835.29 A

Circuit Sizing

Energy Cost

Running 17,040W costs approximately $2.90 per hour at the US average rate of $0.17/kWh (rates last reviewed April 2026). That is $23.17 for 8 hours or about $695.23 per month. See detailed cost breakdown.

AC Conversion Detail

The DC baseline for 17,040W at 24V is 710A. On an AC circuit with a power factor of 0.85, the current rises to 835.29A because reactive current flows alongside the real-power current.

Power Factor Reference

Power factor is the main reason 17,040W draws more current on AC than DC. At PF 1.0 (pure resistive, like a heater), the load pulls 710A at 24V on the single-phase basis the rest of the page uses. At PF 0.80 (typical induction motor), the same 17,040W pulls 887.5A. That is an extra 177.5A just to overcome the reactive component. Use the typical values below as a starting point, not for precise engineering calculations.

Frequently Asked Questions

17,040W at 24V draws 710 amps on DC. For comparison at the same voltage: 710A on DC, 835.29A on AC single-phase at PF 0.85. Actual current depends on the load's power factor.
Yes. Higher voltage means lower current for the same real power. 17,040W at 24V draws 710A on DC. As a resistive-baseline comparison at the same wattage, a DC or PF 1.0 load would draw 1,420A at 12V and 355A at 48V. Doubling the voltage halves the current and also halves the I²R losses in the conductors.
Resistive loads like space heaters and toasters have a power factor of 1.0, so 17,040W at 24V on a single-phase AC basis draws 710A. An induction motor at the same wattage has a PF around 0.80, drawing 887.5A on the same basis. The extra current is reactive, it does no real work but still has to flow through the conductors and breaker.
At 710A on 24V, branch-circuit sizing depends on whether the load is continuous (NEC 210.19(A) applies the 125% continuous-load rule), the equipment nameplate FLA, and the conductor and termination ratings. 24V is a commercial or industrial panel voltage, not a typical household receptacle voltage.
NEC 210.19(A) sizes the conductor and overcurrent device at not less than 125% of any continuous load (a load that runs three hours or more), equivalently 80% of the breaker rating. At 710A (the current the branch conductors actually carry on DC), the minimum breaker that satisfies this is 890A under typical assumptions. Brief non-continuous use can run closer to the full breaker rating, but space heaters, EV chargers, and long-running appliances should be sized for the continuous case.
