How Many Amps Is 473 kW at 460V?

473 kW at 460V draws about 698.44 amps on an AC three-phase circuit at PF 0.85, typical for commercial HVAC, industrial motors, rooftop units, and three-phase panel loads. Actual current varies with equipment power factor and duty cycle.

Formulas

DC: kW to Amps

I(A) = 1000 × P(kW) ÷ V(V)

1000 × 473 ÷ 460 = 473,004 ÷ 460 = 1,028.27 A

AC Single Phase (PF = 0.85)

I(A) = 1000 × P(kW) ÷ (PF × V(V))

473,004 ÷ (0.85 × 460) = 473,004 ÷ 391 = 1,209.73 A

AC Three Phase (PF = 0.85)

I(A) = 1000 × P(kW) ÷ (√3 × PF × VL-L), where VL-L is the line-to-line voltage

473,004 ÷ (1.732 × 0.85 × 460) = 473,004 ÷ 677.21 = 698.44 A

Power Factor Reference (AC three-phase)

How the line current for 473 kW at 460V changes with load power factor, on the same AC three-phase circuit basis the rest of the page uses. DC has no power factor; PF 1.0 represents resistive AC loads.

AC Conversion Comparison

On DC, 473kW at 460V draws 1,028.27A. AC single-phase at PF 0.85 pulls 1,209.73A because reactive current is added on top of the real power. Three-phase at the same voltage needs only 698.44A per line since the same 473kW is shared across three conductors instead of one.

Each destination page leads with the interpretation most common for that voltage, so the amps shown below use the same basis as the page you'd land on: single-phase for residential voltages, three-phase for commercial/industrial panel voltages, DC for low-voltage.

Frequently Asked Questions

473 kW at 460V draws about 698.44 amps on an AC three-phase circuit at PF 0.85. Alternate cases at the same voltage: 1,028.27A on DC, 1,209.73A on AC single-phase.
473 kW equals 473,004 watts. Multiply kilowatts by 1000.
473 kW costs $80.41 per hour at $0.17/kWh (US residential average, last reviewed April 2026). At 8 hours/day that is $19,298.56 per month.
Three-phase at 460V draws 698.44A per line versus 1,209.73A single-phase. Less current per conductor means smaller wire and lower I²R losses.
460V is commercial/industrial panel voltage, not a typical AC EVSE feed to a vehicle. On three-phase 460V, 473 kW works out to about 698.44A 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 473 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.
