1. What is a Single Phase kVA to Amps Calculator?

Definition: This calculator converts apparent power in kilovolt-amps (kVA) to electric current in amps for single-phase AC systems.

Purpose: It helps electricians, engineers, and technicians determine the current draw from electrical equipment based on its power rating.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( I \) — Current (amps)
• \( kVA \) — Apparent power (kilovolt-amps)
• \( V \) — Voltage (volts)

Explanation: The kVA value is multiplied by 1000 to convert to volt-amps, then divided by voltage to find current.

3. Importance of Current Calculation

Details: Proper current calculation ensures correct wire sizing, circuit breaker selection, and prevents electrical system overloads.

4. Using the Calculator

Tips: Enter the apparent power in kVA and system voltage (default 120V). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Why convert kVA to amps?
A: Electrical components are rated by current capacity, while equipment is often rated in kVA, requiring conversion for proper system design.

Q2: What's a typical voltage for single-phase systems?
A: Common voltages are 120V (residential) and 240V (appliances), but always verify your specific system voltage.

Q3: Does this work for three-phase systems?
A: No, use our Three-Phase kVA to Amps calculator for three-phase systems.

Q4: How accurate is this calculation?
A: It provides theoretical current; actual current may vary due to power factor, efficiency, and other factors.

Q5: What if I know watts instead of kVA?
A: Use our Watts to Amps calculator or divide watts by voltage (for purely resistive loads).
