Formulas

DC: kW to Amps

I_(A) = 1000 × P_(kW) ÷ V_(V)

1000 × 8.47 ÷ 12 = 8,465 ÷ 12 = 705.42 A

AC Single Phase (PF = 0.85)

I_(A) = 1000 × P_(kW) ÷ (PF × V_(V))

8,465 ÷ (0.85 × 12) = 8,465 ÷ 10.2 = 829.9 A

Power Factor Reference (DC)

How the line current for 8.47 kW at 12V 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	8.47 kW at 12V (DC)
Resistive (heaters, incandescent)	1	705.42 A
Fluorescent lamps	0.95	705.42 A
LED lighting	0.9	705.42 A
Synchronous motors	0.9	705.42 A
Typical mixed loads	0.85	705.42 A
Induction motors (full load)	0.8	705.42 A
Computers (without PFC)	0.65	705.42 A
Induction motors (no load)	0.35	705.42 A

AC Conversion Comparison

On DC, 8.47kW at 12V draws 705.42A. AC single-phase at PF 0.85 pulls 829.9A because reactive current is added on top of the real power.

Circuit Type	Formula	Result
DC	8,465 ÷ 12	705.42 A
AC Single Phase (PF 0.85)	8,465 ÷ (0.85 × 12)	829.9 A

Frequently Asked Questions

How many amps is 8.47 kW at 12V?expand_more

8.47 kW at 12V draws about 705.42 amps on DC. Alternate cases at the same voltage: 829.9A on AC single-phase.

Is 8.47 kW single-phase or three-phase?expand_more

8.47 kW is available in both, but three-phase is more common for commercial HVAC, rooftop units, and motors once you reach this range.

How does power factor affect the amps for 8.47 kW at 12V?expand_more

On AC single-phase, current scales inversely with power factor. At PF 1.0 (pure resistive, like a heater), 8.47 kW at 12V draws 705.42A. At PF 0.80 (typical induction motor), the same real power draws 881.77A. The extra current is reactive and does no real work, but still flows through the wire and the breaker.

How many amps does a 8.47 kW EV charger draw at 12V?expand_more

At 12V, this is Level 1 territory (120V AC, single-phase, typically 12-16A). A 8.47 kW draw on a standard 120V household outlet is at or above the 1,440W NEC 210.19(A) continuous figure, which is why Level 1 EVSE ships at 1.4-1.9 kW and takes 20+ hours for a full charge. If you need 8.47 kW of charging, you want Level 2 on a 240V dedicated circuit, not 120V.

Why do industrial systems use kW instead of watts?expand_more

Industrial equipment operates at higher power levels. 8.47 kW is easier to express than 8,465W. The math is identical, just scaled by 1000.
