Formulas

DC: kW to Amps

I_(A) = 1000 × P_(kW) ÷ V_(V)

1000 × 16.8 ÷ 24 = 16,800 ÷ 24 = 700 A

AC Single Phase (PF = 0.85)

I_(A) = 1000 × P_(kW) ÷ (PF × V_(V))

16,800 ÷ (0.85 × 24) = 16,800 ÷ 20.4 = 823.53 A

Power Factor Reference (DC)

How the line current for 16.8 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	16.8 kW at 24V (DC)
Resistive (heaters, incandescent)	1	700 A
Fluorescent lamps	0.95	700 A
LED lighting	0.9	700 A
Synchronous motors	0.9	700 A
Typical mixed loads	0.85	700 A
Induction motors (full load)	0.8	700 A
Computers (without PFC)	0.65	700 A
Induction motors (no load)	0.35	700 A

AC Conversion Comparison

On DC, 16.8kW at 24V draws 700A. AC single-phase at PF 0.85 pulls 823.53A because reactive current is added on top of the real power.

Circuit Type	Formula	Result
DC	16,800 ÷ 24	700 A
AC Single Phase (PF 0.85)	16,800 ÷ (0.85 × 24)	823.53 A

Frequently Asked Questions

How many amps is 16.8 kW at 24V?expand_more

16.8 kW at 24V draws about 700 amps on DC. Alternate cases at the same voltage: 823.53A on AC single-phase.

Is 16.8 kW single-phase or three-phase?expand_more

16.8 kW is typically three-phase in commercial and industrial settings.

What is the formula for kW to amps?expand_more

DC: Amps = (kW × 1000) ÷ Volts. AC single-phase: Amps = (kW × 1000) ÷ (Volts × PF). AC three-phase: Amps = (kW × 1000) ÷ (Volts_L-L × √3 × PF).

How much does 16.8 kW cost to run?expand_more

16.8 kW costs $2.86 per hour at $0.17/kWh (US residential average, last reviewed April 2026). At 8 hours/day that is $685.44 per month.

Why do industrial systems use kW instead of watts?expand_more

Industrial equipment operates at higher power levels. 16.8 kW is easier to express than 16,800W. The math is identical, just scaled by 1000.
