Formulas

DC: kW to Amps

I_(A) = 1000 × P_(kW) ÷ V_(V)

1000 × 376.18 ÷ 400 = 376,175 ÷ 400 = 940.44 A

AC Single Phase (PF = 0.85)

I_(A) = 1000 × P_(kW) ÷ (PF × V_(V))

376,175 ÷ (0.85 × 400) = 376,175 ÷ 340 = 1,106.4 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

376,175 ÷ (1.732 × 0.85 × 400) = 376,175 ÷ 588.88 = 638.78 A

AC Conversion Comparison

On DC, 376.18kW at 400V draws 940.44A. AC single-phase at PF 0.85 pulls 1,106.4A because reactive current is added on top of the real power. Three-phase at the same voltage needs only 638.78A per line since the same 376.18kW is shared across three conductors instead of one.

Circuit Type	Formula	Result
DC	376,175 ÷ 400	940.44 A
AC Single Phase (PF 0.85)	376,175 ÷ (0.85 × 400)	1,106.4 A
AC Three Phase (PF 0.85)	376,175 ÷ (1.732 × 0.85 × 400)	638.78 A
