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)

18,024 ÷ 24 = 751 A

AC Single Phase (PF = 0.85)

I(A) = P(W) ÷ (PF × V(V))

18,024 ÷ (0.85 × 24) = 18,024 ÷ 20.4 = 883.53 A

Circuit Sizing

Energy Cost

Running 18,024W costs approximately $3.06 per hour at the US average rate of $0.17/kWh (rates last reviewed April 2026). That is $24.51 for 8 hours or about $735.38 per month. See detailed cost breakdown.

AC Conversion Detail

The DC baseline for 18,024W at 24V is 751A. On an AC circuit with a power factor of 0.85, the current rises to 883.53A because reactive current flows alongside the real-power current.

Power Factor Reference

Power factor is the main reason 18,024W draws more current on AC than DC. At PF 1.0 (pure resistive, like a heater), the load pulls 751A at 24V on the single-phase basis the rest of the page uses. At PF 0.80 (typical induction motor), the same 18,024W pulls 938.75A. That is an extra 187.75A just to overcome the reactive component. Use the typical values below as a starting point, not for precise engineering calculations.

Frequently Asked Questions

18,024W at 24V draws 751 amps on DC. For comparison at the same voltage: 751A on DC, 883.53A on AC single-phase at PF 0.85. Actual current depends on the load's power factor.
At 751A 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.
Yes. Higher voltage means lower current for the same real power. 18,024W at 24V draws 751A on DC. As a resistive-baseline comparison at the same wattage, a DC or PF 1.0 load would draw 1,502A at 12V and 375.5A 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 18,024W at 24V on a single-phase AC basis draws 751A. An induction motor at the same wattage has a PF around 0.80, drawing 938.75A 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 the US residential average of $0.17/kWh (last reviewed April 2026), 18,024W costs $3.06 per hour and $24.51 for 8 hours. Rates vary by utility and time of day.
