Max Demand — Calculation

It is industry best practice to add a "spare capacity" (usually 10-20%) to the final calculation to allow for future upgrades or additional equipment. Practical Example (Residential) Imagine a small house with: 20 points (Approx. 1000W) Outlets: 15 points (Approx. 3000W) Air Con: 5000W Using a simplified diversity factor: Lighting: (Full load for first 3A, 50% for remainder) →right arrow Outlets: (Full load for first 10A, 50% for remainder) →right arrow Air Con: (Usually 100% of the full load) →right arrow
