1. What is Electrical Load Calculation?

Definition: This calculator computes the total electrical load in kilowatts (kW) by summing individual loads in watts.

Purpose: It helps electricians and engineers determine the total power requirement for electrical systems.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( P_{kW} \) — Total power in kilowatts
• \( P_{load} \) — Individual load in watts

Explanation: Each load in watts is converted to kilowatts (divided by 1000) and then summed to get the total load.

3. Importance of Load Calculation

Details: Proper load calculation ensures correct sizing of electrical components, prevents circuit overloads, and maintains system safety.

4. Using the Calculator

Tips: Enter up to three load values in watts. The calculator will sum them and display the total in kilowatts.

5. Frequently Asked Questions (FAQ)

Q1: Why convert watts to kilowatts?
A: Kilowatts are the standard unit for electrical system design and utility billing.

Q2: What's a typical residential load?
A: Average homes range from 3-8 kW, but this varies with appliances and size.

Q3: Should I include all devices?
A: Include all continuous loads and the largest intermittent loads.

Q4: How does this relate to circuit breakers?
A: Breakers are sized based on load calculations to prevent overheating.

Q5: What about power factor?
A: This calculator assumes unity power factor (resistive loads).
