⚙️ What is Electrical Load Calculation?
Electrical load calculation is the process of determining the total power consumed by all electrical devices in a system.
It includes:
- Lighting load
- Power load (sockets, appliances)
- HVAC load
- Equipment load
📊 Key Components in Load Calculation
1. Connected Load
Total load of all equipment (in watts or kW)
2. Demand Factor
Not all equipment runs simultaneously
3. Diversity Factor
Used for optimizing system design
🧮 Example Calculation
| Equipment | Qty | Watt | Total |
|---|---|---|---|
| Lights | 10 | 20W | 200W |
| Fans | 5 | 75W | 375W |
| AC | 2 | 1500W | 3000W |
👉 Total Load = 3575W
