Maximum Demand Calculation -

: Overestimating demand leads to unnecessarily expensive cables and oversized components.

The "secret sauce" of maximum demand calculation is the (or Demand Factor). maximum demand calculation

: Identify every individual circuit and its total connected load in watts or amperes. maximum demand calculation

| Term | Unit | Description | |-------|------|--------------| | Connected Load | kW, A | Sum of all nameplate ratings | | Maximum Demand (MD) | kW, kVA | Highest average load over demand interval | | Demand Interval | Minutes | 15, 30, or 60 (utility-specific) | | Load Factor | % | (Average Load / MD) × 100 | | Diversity Factor | — | Sum of individual MDs / System MD | | Coincidence Factor | — | Inverse of diversity factor | maximum demand calculation

Maximum demand = 400 kW x 0.8 = 320 kW
