Formulas

DC: kW to Amps

I_(A) = 1000 × P_(kW) ÷ V_(V)

1000 × 462.06 ÷ 460 = 462,059 ÷ 460 = 1,004.48 A

AC Single Phase (PF = 0.85)

I_(A) = 1000 × P_(kW) ÷ (PF × V_(V))

462,059 ÷ (0.85 × 460) = 462,059 ÷ 391 = 1,181.74 A

AC Three Phase (PF = 0.85)

I_(A) = 1000 × P_(kW) ÷ (√3 × PF × V_L-L), where V_L-L is the line-to-line voltage

462,059 ÷ (1.732 × 0.85 × 460) = 462,059 ÷ 677.21 = 682.28 A

Computers (without PFC)	0.65	892.21 A
Induction motors (no load)	0.35	1,656.96 A

AC Conversion Comparison

On DC, 462.06kW at 460V draws 1,004.48A. AC single-phase at PF 0.85 pulls 1,181.74A because reactive current is added on top of the real power. Three-phase at the same voltage needs only 682.28A per line since the same 462.06kW is shared across three conductors instead of one.

Circuit Type	Formula	Result
DC	462,059 ÷ 460	1,004.48 A
AC Single Phase (PF 0.85)	462,059 ÷ (0.85 × 460)	1,181.74 A
AC Three Phase (PF 0.85)	462,059 ÷ (1.732 × 0.85 × 460)	682.28 A

Frequently Asked Questions

How many amps is 462.06 kW at 460V?expand_more

462.06 kW at 460V draws about 682.28 amps on an AC three-phase circuit at PF 0.85. Alternate cases at the same voltage: 1,004.48A on DC, 1,181.74A on AC single-phase.

How much does 462.06 kW cost to run?expand_more

462.06 kW costs $78.55 per hour at $0.17/kWh (US residential average, last reviewed April 2026). At 8 hours/day that is $18,852.01 per month.

How many amps does a 462.06 kW EV charger draw at 460V?expand_more

460V is commercial/industrial panel voltage, not a typical AC EVSE feed to a vehicle. On three-phase 460V, 462.06 kW works out to about 682.28A per line (three-phase at PF 0.85). In practice, 400-480V three-phase is usually the AC input to a DC fast charger (50-350 kW CCS/NACS stations like Tesla Superchargers), which rectifies to DC and delivers that directly to the vehicle, rather than an AC EVSE connector. A 462.06 kW figure at 460V is most likely the AC feed to a smaller commercial cabinet or the control-side input of a larger DC fast charger, not an at-the-car AC current.

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).

Is 462.06 kW single-phase or three-phase?expand_more

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