Maximum Demand Calculation !!hot!!

Maximum demand calculation is a critical electrical engineering process used to determine the highest likely power load of an installation. It ensures that infrastructure like cables and circuit breakers are safely sized without unnecessary over-investment. ⚡ Core Concept: Why Not Just Sum Everything?

Worked Example (Small Office)

• Lighting: 5 kW → Apply 100% first 3kW (3kW) + 50% of 2kW (1kW) = 4 kW
• AC Units: 3 units × 2 kW each (6 kW) → Diversity 70% = 4.2 kW
• Receptacles: 10 kW → 50% = 5 kW
• Total MD = 4 + 4.2 + 5 = 13.2 kW

[ MD = \sum (Load_i \times Diversity\ Factor_i \times Load\ Factor_i) ] Lighting: 5 kW → Apply 100% first 3kW
