Calculation [patched]: Maximum Demand

: Often considered the most accurate, this involves recording the highest sustained current draw over a set period (e.g., 30 minutes) using a recording device at the main board. Limitation

. He realizes that if every light, the cafe’s oven, the workshop's heavy saws, and the office ACs all ran at 100% power at the exact same second, the building would need a massive, expensive power supply. maximum demand calculation

: A common thumb rule is to take 100% of the largest circuit's rating and 40% of all remaining circuits. : Often considered the most accurate, this involves

| Load | Connected (kW) | Demand Factor | Contribution (kW) | |-------|----------------|---------------|-------------------| | Lighting | 4.0 | 0.8 | 3.2 | | HVAC | 6.0 | 0.8 | 4.8 | | Elevator | 7.5 | 0.6 | 4.5 | | Sockets | 10.0 | 0.3 | 3.0 | | Pumps | 4.4 | 0.7 | 3.08 | | | | | 18.58 kW | : A common thumb rule is to take

MD is not an instantaneous spike; it is an average over a window (typically 15 minutes).
