Power Calculation Formula:
From: | To: |
The 15 Amp to Wattage calculation converts current (15 amps) to power (watts) using the voltage. This is essential for electrical system design and safety calculations.
The calculator uses the power formula:
Where:
Explanation: The formula calculates power consumption for a 15 amp circuit at a given voltage.
Details: Accurate power calculation is crucial for circuit design, breaker sizing, and ensuring electrical safety in 15 amp circuits.
Tips: Enter the voltage in volts. The value must be valid (voltage > 0).
Q1: What's the typical voltage for this calculation?
A: Common voltages are 120V (North America) or 230V (Europe) for residential circuits.
Q2: Can I use this for other amperages?
A: No, this calculator is specifically for 15 amp circuits. For other amperages, use P = V × I.
Q3: What's the maximum wattage for a 15A/120V circuit?
A: 1800 watts (120V × 15A), though continuous loads should be limited to 1440W (80% of capacity).
Q4: Does this account for power factor?
A: No, this assumes purely resistive loads. For reactive loads, multiply by power factor.
Q5: Why is this calculation important?
A: It helps prevent circuit overloads, which can cause overheating and fire hazards.
