\(Demand \space factor={Maximum \space demand\over Connected\space load}\)
- For smaller motors (<10 HP), not all motors operate at full load continuously, so the demand factor is less than 1.
- A typical range for small motor loads is 0.75 to 0.85, meaning only 75% to 85% of the connected load is expected to operate at peak demand.
- Thus, the demand factor for motors below 10 HP should generally be around 0.75.
Demand factor for various loads:
- Residential load (over 1 kW) = 0.5
- Residential load (< 0.25 kW) = Less than 0.5
- Motor Load (< 10 HP) = 0.75
- Commercial load (for Restaurants) = 0.7
