Formulas

DC: kW to Amps

I_(A) = 1000 × P_(kW) ÷ V_(V)

1000 × 917.65 ÷ 460 = 917,649 ÷ 460 = 1,994.89 A

AC Single Phase (PF = 0.85)

I_(A) = 1000 × P_(kW) ÷ (PF × V_(V))

917,649 ÷ (0.85 × 460) = 917,649 ÷ 391 = 2,346.93 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

917,649 ÷ (1.732 × 0.85 × 460) = 917,649 ÷ 677.21 = 1,355 A

AC Conversion Comparison

On DC, 917.65kW at 460V draws 1,994.89A. AC single-phase at PF 0.85 pulls 2,346.93A because reactive current is added on top of the real power. Three-phase at the same voltage needs only 1,355A per line since the same 917.65kW is shared across three conductors instead of one.

Frequently Asked Questions

How many amps is 917.65 kW at 460V?expand_more

917.65 kW at 460V draws about 1,355 amps on an AC three-phase circuit at PF 0.85. Alternate cases at the same voltage: 1,994.89A on DC, 2,346.93A on AC single-phase.

How much does 917.65 kW cost to run?expand_more

917.65 kW costs $156.00 per hour at $0.17/kWh (US residential average, last reviewed April 2026). At 8 hours/day that is $37,440.08 per month.

How many amps does a 917.65 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, 917.65 kW works out to about 1,355A 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 917.65 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.

How does three-phase affect the amps for 917.65 kW?expand_more

Three-phase at 460V draws 1,355A per line versus 2,346.93A single-phase. Less current per conductor means smaller wire and lower I²R losses.

Is 917.65 kW single-phase or three-phase?expand_more

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