⚙️ 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
