1. What is an Electrical Load Calculator for Home?

Definition: This calculator estimates the total electrical load of a home by summing the power consumption of all appliances and converting to kilowatts.

Purpose: It helps homeowners and electricians determine the total power requirements for proper electrical system design and safety.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( P_{kW} \) — Total electrical load (kilowatts)
• \( P_i \) — Power of individual appliances (watts)

Explanation: The wattage of all appliances are summed and divided by 1000 to convert to kilowatts.

3. Importance of Electrical Load Calculation

Details: Proper load calculation ensures your electrical system can handle demand, prevents circuit overloads, and helps with energy planning.

4. Using the Calculator

Tips: Enter the number of appliances and their individual wattage ratings. Common appliance wattages:

• Refrigerator: 150-400 watts
• LED TV: 30-100 watts
• AC Unit: 1000-3500 watts
• Microwave: 600-1200 watts

5. Frequently Asked Questions (FAQ)

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

Q2: How do I find appliance wattage?
A: Check manufacturer labels, specifications, or use a wattage meter.

Q3: Should I include all appliances?
A: Yes, for accurate load calculation, include everything that uses electricity.

Q4: What about appliances not always running?
A: The calculation shows peak load when everything runs simultaneously.

Q5: How does this relate to circuit breakers?
A: Your main breaker should handle at least 125% of your calculated load.
