I = (kVA x 1000) / V
Single phase conversion divides apparent power by circuit voltage to estimate current. It is useful for quick checks before moving into detailed design.
Example
- 5 kVA at 230V -> 21.7 A (single-phase)
- 12 kVA at 120V -> 100.0 A (single-phase)
FAQ
What is the single phase kVA to amps formula?
Use I = (kVA x 1000) / V for single phase systems.
Is line voltage used in single phase conversion?
Yes, use the actual supply voltage of the circuit, such as 120 V or 230 V.
What voltage should I use?
Use the rated operating voltage of your single phase load to keep the estimate practical.
