1. What is House Load Calculation Electrical?

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

Purpose: Helps homeowners and electricians determine the total electrical demand for proper circuit sizing and energy management.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ P_{kW} = \sum \left( \frac{P_{load}}{1000} \right) \]

Where:

Explanation: Each appliance's wattage is divided by 1000 to convert to kilowatts, then all values are summed for the total load.

3. Importance of Electrical Load Calculation

Details: Proper load calculation ensures electrical systems are not overloaded, prevents circuit breaker trips, and helps with energy efficiency planning.

4. Using the Calculator

Tips: Enter the wattage of up to three appliances. Leave fields blank for unused appliance slots. All values must be ≥ 0.

5. Frequently Asked Questions (FAQ)

Q1: Why convert to kilowatts?
A: Kilowatts are the standard unit for household electrical load measurement and utility billing.

Q2: Where can I find appliance wattage?
A: Check appliance nameplates, manuals, or use a wattage meter. Typical values: fridge (150-400W), TV (50-200W), AC (1000-3500W).

Q3: Should I include all appliances?
A: For full load calculation, include all major appliances that might run simultaneously.

Q4: How does this relate to circuit breakers?
A: Total load should not exceed 80% of circuit capacity (e.g., 16A breaker = 1920W max continuous load).

Q5: What about power factor?
A: This calculator assumes resistive loads. For motors or inductive loads, consider power factor in detailed calculations.
