How to Calculate Maximum Demand for Electrical Installations
A practical guide to calculating maximum demand — formulae, diversity factors, worked examples, and BS 7671 requirements.
Demand Factor, Diversity Factor, Utilization Factor, Load Factor
Energy Demand ManagementDemand FactorDiversity Factor / Simultaneity FactorLoad FactorUtilization FactorCoincidence FactorDemand Factor = Maximum demand of a system / Total connected load on the system. Demand factor is always less than one. For example, if a residence having 6000W equipment connected has a maximum demand of 300W, than demand factor = 6000W / 3300W = 55%. The lower the demand factor, the less system capacity required to serve the connected load. Feede...See more on electrical-engineering-portal electriciancalc
