Maximum Demand Calculation «Pro ✪»

Categorise every electrical load (lighting, cooking, HVAC, motors) into groups as per standard tables (e.g., Table C1 or C2 in AS/NZS 3000). Determine Connected Load Calculate the full current for each circuit, often using for fixed loads. Apply Diversity

The most accurate method for existing buildings. A recording device (data logger) measures the highest sustained current draw over a 30-minute period. Limitation: maximum demand calculation

: Often used during the design phase before a building is constructed. It involves listing all equipment and applying diversity factors —the assumption that not all appliances will run simultaneously. Categorise every electrical load (lighting

Used for existing buildings where you can monitor actual usage over time using a data logger. maximum demand calculation
