Automatic Water Pump Control with Float Switches!This wiring diagram shows how upper and lower tank float switches control a water pump through a contactor. The system automatically starts or stops the pump according to the water level, helping prevent tank overflow and dry running. A practical solution for water-level automation.

💡 LIGHTING LOAD CALCULATION

❓ How do you calculate the total lighting load of a room or building?

📐 BASIC FORMULA:

Total Lighting Load (W) = Number of Light Fixtures × Wattage per Fixture

🔹 EXAMPLE:

Room Size = 10 m × 8 m
Number of LED Lights = 20
Wattage per Light = 40 W

STEP 1: Calculate Total Lighting Load

Total Load = 20 × 40

= 800 W

STEP 2: Convert Watts to Kilowatts

Lighting Load (kW) = 800 ÷ 1000

= 0.8 kW

STEP 3: Calculate Lighting Load per Square Metre

Floor Area = 10 × 8

= 80 m²

Lighting Load Density = 800 ÷ 80

= 10 W/m²

✅ FINAL ANSWER:

Total Lighting Load = 800 W (0.8 kW)

Lighting Load Density = 10 W/m²

🔹 WHY IS LIGHTING LOAD CALCULATION IMPORTANT?

• Electrical circuit design
• Cable and breaker selection
• Distribution board load calculation
• Energy consumption estimation
• Lighting design and planning

📌 IMPORTANT NOTE:

Lighting load in watts is not the same as illumination level in lux. Required lux depends on the room's purpose, applicable lighting standards, fixture distribution and design conditions.

⚠️ DESIGN NOTE: Final electrical design should consider driver losses, control equipment, applicable demand factors, circuit protection and local electrical regulations.
