1. What is Luminous Load Calculation?

The Luminous Load Calculation is a method to determine the total power requirement by summing up the individual power consumption of all appliances. It helps in proper electrical system design and sizing.

2. How Does the Calculator Work?

The calculator uses the simple summation formula:

Where:

• Appliance Power — Power consumption of each appliance in Watts (W)

Explanation: The calculation simply adds up the power requirements of all connected appliances to determine the total load.

3. Importance of Load Calculation

Details: Accurate load calculation is essential for proper electrical system design, circuit breaker sizing, and ensuring safe operation without overloading.

4. Using the Calculator

Tips: Enter power consumption of each appliance in Watts. At least one appliance power is required. Additional appliances are optional.

5. Frequently Asked Questions (FAQ)

Q1: What if I have more than 3 appliances?
A: You can either add them sequentially in multiple calculations or sum them manually before entering.

Q2: Should I use rated power or actual power?
A: For safety, always use the rated (maximum) power consumption of appliances.

Q3: How does this relate to circuit breaker sizing?
A: The total load should not exceed 80% of the circuit breaker's rated capacity for safety.

Q4: What about power factor?
A: This simple calculation assumes unity power factor. For precise calculations, power factor should be considered.

Q5: Can I use this for commercial installations?
A: While the principle is the same, commercial installations typically require more detailed load calculations.
