700

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)

16,800 ÷ 24 = 700 A

AC Single Phase (PF = 0.85)

I_(A) = P_(W) ÷ (PF × V_(V))

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

Circuit Sizing

Energy Cost

Running 16,800W costs approximately $2.86 per hour at the US average rate of $0.17/kWh (rates last reviewed April 2026). That is $22.85 for 8 hours or about $685.44 per month. See detailed cost breakdown.

AC Conversion Detail

The DC baseline for 16,800W at 24V is 700A. On an AC circuit with a power factor of 0.85, the current rises to 823.53A because reactive current flows alongside the real-power current.

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

Power Factor Reference

Power factor is the main reason 16,800W draws more current on AC than DC. At PF 1.0 (pure resistive, like a heater), the load pulls 700A at 24V on the single-phase basis the rest of the page uses. At PF 0.80 (typical induction motor), the same 16,800W pulls 875A. That is an extra 175A just to overcome the reactive component. Use the typical values below as a starting point, not for precise engineering calculations.

Fluorescent lamps	0.95	736.84 A
LED lighting	0.9	777.78 A
Synchronous motors	0.9	777.78 A

Computers (without PFC)	0.65	1,076.92 A

Frequently Asked Questions

How many amps is 16,800W at 24V? expand_more

16,800W at 24V draws 700 amps on DC. For comparison at the same voltage: 700A on DC, 823.53A on AC single-phase at PF 0.85. Actual current depends on the load's power factor.

Why does AC draw more amps than DC for 16,800W? expand_more

AC circuits with reactive loads have a power factor below 1.0, so they draw extra current. At PF 0.85, 16,800W at 24V draws 823.53A instead of 700A (DC). That is about 18% more current for the same real power.

Is 24V a standard outlet voltage? expand_more

24V is not a standard household receptacle voltage in the US. It is used on commercial or industrial panels and typically feeds hardwired equipment or specialty twistlock receptacles, not plug-in appliances. Any 16,800W load at this voltage is a dedicated-circuit, nameplate-driven install, not a plug-in decision.

Does voltage affect how many amps 16,800W draws? expand_more

Yes. Higher voltage means lower current for the same real power. 16,800W at 24V draws 700A on DC. As a resistive-baseline comparison at the same wattage, a DC or PF 1.0 load would draw 1,400A at 12V and 350A at 48V. Doubling the voltage halves the current and also halves the I²R losses in the conductors.

Why does a 16,800W resistive heater draw fewer amps than a 16,800W motor at 24V? expand_more

Resistive loads like space heaters and toasters have a power factor of 1.0, so 16,800W at 24V on a single-phase AC basis draws 700A. An induction motor at the same wattage has a PF around 0.80, drawing 875A on the same basis. The extra current is reactive, it does no real work but still has to flow through the conductors and breaker.
