1. What is 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 flow based on power rating and voltage.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

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

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

3. Importance of Current Calculation

Details: Accurate current calculation ensures proper wire sizing, circuit breaker selection, and electrical system safety.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: Is this for AC or DC systems?
A: This calculator is for single-phase AC systems. For DC, use I = P/V (no power factor consideration).

Q2: Does this account for power factor?
A: No, kVA already includes power factor. For true power (kW) calculations, you'd need the power factor.

Q3: What's a typical voltage value?
A: Common values are 120V (US residential), 230V (EU residential), or 240V (US appliances).

Q4: How do I find the kVA rating?
A: Check equipment nameplates or specifications. For transformers, it's usually clearly marked.

Q5: Can I use this for three-phase systems?
A: No, use our Three-Phase kVA to Amps calculator for three-phase systems.
