Formulas

DC: kW to Amps

I_(A) = 1000 × P_(kW) ÷ V_(V)

1000 × 605.45 ÷ 480 = 605,445 ÷ 480 = 1,261.34 A

AC Single Phase (PF = 0.85)

I_(A) = 1000 × P_(kW) ÷ (PF × V_(V))

605,445 ÷ (0.85 × 480) = 605,445 ÷ 408 = 1,483.93 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

605,445 ÷ (1.732 × 0.85 × 480) = 605,445 ÷ 706.66 = 856.75 A

AC Conversion Comparison

On DC, 605.45kW at 480V draws 1,261.34A. AC single-phase at PF 0.85 pulls 1,483.93A because reactive current is added on top of the real power. Three-phase at the same voltage needs only 856.75A per line since the same 605.45kW is shared across three conductors instead of one.

Circuit Type	Formula	Result
DC	605,445 ÷ 480	1,261.34 A
AC Single Phase (PF 0.85)	605,445 ÷ (0.85 × 480)	1,483.93 A
AC Three Phase (PF 0.85)	605,445 ÷ (1.732 × 0.85 × 480)	856.75 A
