Overview
This calculator helps you determine the electrical current (amperage) flowing in a circuit for a given apparent power (kVA) and voltage. This is critical for selecting the correct wire size and breaker rating in electrical installations.
💡
Pro Tips
In three-phase systems, I = (kVA × 1000) / (√3 × V).
Always design for the maximum current to avoid overheating and fire hazards.
Voltage is the Line-to-Line (L-L) value for three-phase calculations.

Fun Facts
"Amperage is named after André-Marie Ampère, a French physicist who was one of the founders of electromagnetism."
"A typical household circuit is rated for 15 or 20 Amps."
"High-voltage transmission lines carry electricity at low amperage to minimize energy loss as heat."
