For three-phase systems: Amps = (kVA × 1000) ÷ (Voltage × √3). The √3 factor (1.732) accounts for the phase relationship in balanced three-phase electrical loads.
A kVA to amps calculator requires kVA rating, voltage, and system type (single/three-phase) as inputs. Simply enter these values and the calculator automatically applies the correct conversion formula.
1 kVA equals 4.17 amps at 240V single-phase or 2.4 amps at 240V three-phase. The exact amperage depends on your system voltage and phase configuration.
Generator kVA to amps uses the same formula: Amps = (kVA × 1000) ÷ Voltage for single-phase systems. Always check your generator’s nameplate voltage for accurate amperage calculations.
A reliable kVA to amps chart includes common voltages (120V, 240V, 480V) for both single and three-phase systems. Charts typically cover 1-100 kVA ranges with corresponding amp values clearly specified.
1 kVA equals 1000 watts only when power factor is 1.0 (unity). In real applications, watts = kVA × power factor, where power factor ranges from 0.8 to 1.0.
5 kVA converts to 4000-5000 watts depending on power factor (typically 0.8-1.0). Multiply your kVA by the equipment’s specific power factor for accurate watt calculations.
15 kVA equals 36.1 amps at 240V three-phase or 18.1 amps at 480V three-phase. Use formula: Amps = (15 × 1000) ÷ (Voltage × 1.732) for three-phase calculations.
