Formulas

DC: kW to Amps

I_(A) = 1000 × P_(kW) ÷ V_(V)

1000 × 17.66 ÷ 24 = 17,664 ÷ 24 = 736 A

AC Single Phase (PF = 0.85)

I_(A) = 1000 × P_(kW) ÷ (PF × V_(V))

17,664 ÷ (0.85 × 24) = 17,664 ÷ 20.4 = 865.88 A

Power Factor Reference (DC)

How the line current for 17.66 kW at 24V changes with load power factor, on the same DC circuit basis the rest of the page uses. DC has no power factor; PF 1.0 represents resistive AC loads.

Load Type	PF	17.66 kW at 24V (DC)
Resistive (heaters, incandescent)	1	736 A
Fluorescent lamps	0.95	736 A
LED lighting	0.9	736 A
Synchronous motors	0.9	736 A
Typical mixed loads	0.85	736 A
Induction motors (full load)	0.8	736 A
Computers (without PFC)	0.65	736 A
Induction motors (no load)	0.35	736 A

AC Conversion Comparison

On DC, 17.66kW at 24V draws 736A. AC single-phase at PF 0.85 pulls 865.88A because reactive current is added on top of the real power.

Circuit Type	Formula	Result
DC	17,664 ÷ 24	736 A
AC Single Phase (PF 0.85)	17,664 ÷ (0.85 × 24)	865.88 A

How much does 17.66 kW cost to run?expand_more

17.66 kW costs $3.00 per hour at $0.17/kWh (US residential average, last reviewed April 2026). At 8 hours/day that is $720.69 per month.

How does power factor affect the amps for 17.66 kW at 24V?expand_more

On AC single-phase, current scales inversely with power factor. At PF 1.0 (pure resistive, like a heater), 17.66 kW at 24V draws 736A. At PF 0.80 (typical induction motor), the same real power draws 920A. The extra current is reactive and does no real work, but still flows through the wire and the breaker.
