is the process of estimating the highest amount of electrical power a building or installation will draw at any single point in time.
Demand Factor=Maximum DemandTotal Connected LoadDemand Factor equals the fraction with numerator Maximum Demand and denominator Total Connected Load end-fraction
Are you working with a power supply?
Method 2: Calculation by Assessment and Monitoring (Empirical) maximum demand calculation
Group everything into categories (Lighting, Power Outlets, Cooking, HVAC, Motors).
This is the inverse of the diversity factor but preferred by some utilities.
Maximum Demand=Sum of Individual Loads×Demand Factor [0.5.4]Maximum Demand equals Sum of Individual Loads cross Demand Factor [0.5.4] A house has 6000W6000 cap W total connected load, but the maximum demand might only be 3300W3300 cap W is the process of estimating the highest amount
Apply standard factors (based on local electrical codes) to each category.
Properly sizing cables and circuit breakers prevents overheating, tripping, and fires.
: 20 double sockets (assumed standard 10A rating per socket group) Air Conditioning : 2 units at 3,000W each = 6,000W This is the inverse of the diversity factor
For many industrial and commercial users, utility companies charge based on the highest recorded peak (Maximum Demand Charge). The Secret Ingredient: Diversity Factors
Situation: A two‑storey office with:
The ratio of the maximum demand of a system to its total connected load. It is always less than or equal to 1.
Apply diversity factors and demand factors to the connected loads.
