Maximum Demand and Diversity FAQ's
How to calculate diversity
In order to apply diversity to the total full load we need to ascertain the type of load and how frequently it is likely to be used.
- FL = Total Full Load
- DF = Diversity Factor
- DR = Diversified Result
FL x DF = DL
Note that depending on the type of load the formula above may differ, such as FL, (sum) = DR
Calculating & applying the appropriate diversity factors to a connected load requires detailed knowledge and experience, all relevant factors should be considered.

How to calculate maximum demand
To calculate the maximum demand of an electrical installation we may use the following formula:
Load 1 + Load 2 + Load 3 = Total Connected Load.
Total Connected Load x Diversity = Maximum Demand.
Note: When calculating the maximum demand for an electrical installation, the type of use of the installation / number of occupants may change throughout the life of the installation therefore the maximum demand may change.
Calculating maximum demand is not an exact science due to the many variables, many other factors should also be considered when calculating the maximum demand.
