It dictates the size of your main incoming transformer, circuit breakers, and busbars. The Core Concepts: Diversity and Demand Factors

Add up the results from each category to find the . 4. The Formula maximum demand calculation

You rarely turn on every light, appliance, and motor in a building at the exact same time. Maximum demand calculation relies on two key principles: It dictates the size of your main incoming

Practical Example: A Small Residential Unit Lighting: 2,000W (Diversity 66%) = 1,320W Sockets: 10,000W (Diversity 40%) = 4,000W The Formula You rarely turn on every light,

3,000W (Diversity 100% of first 10A + 30% of rest) ≈ 1,800W Total Calculated Demand: 7,120W

Whether you are an engineer designing a new skyscraper or a homeowner upgrading to an EV charger, understanding maximum demand ensures the lights stay on without overpaying for infrastructure. Why Calculate Maximum Demand?
