Itotal=4 A+25 A+13.05 A=42.05 Acap I sub total end-sub equals 4 A plus 25 A plus 13.05 A equals 42.05 A ✅ Final Calculation Summary
For example, if a customer consumes 150 kWh over a 30-minute (0.5-hour) interval, the demand for that interval is ( 150 / 0.5 = 300 ) kW. To find the MD, a utility meter performs this calculation for every consecutive, overlapping interval and records the peak value.
Ensuring the main incoming fuse and cables can handle the peak load.
If the power factor is low, the kVA demand rises, which can trigger higher demand charges or penalty clauses. Example: a 24.75 kW peak load at 0.86 power factor yields a maximum demand of 24.75 / 0.86 = 28.77 kVA.
Step 1 – Sum connected load. 5 + 4.5 + 8 + 3.5 + 3 = 24 kW connected.
Categorize every electrical item in the building. Common categories include: Lighting circuits Socket-outlets (Power points) Cooking appliances (Ovens/Cooktops) Space heating/cooling (HVAC) Water heaters Motors and pumps 2. Determine the Load of Each Category
Find the wattage or amperage for each item. For example, a 2.4kW heater draws 10 Amps on a standard 240V circuit ( 3. Apply Diversity Factors
includes a maximum demand module that provides fast and accurate calculations in accordance with standard rules. Its automatic phase balancing algorithm ensures both maximum demand and phase imbalance are minimized. The software automatically calculates the lowest possible maximum demand with optimal phase balancing.
