8+ Generator Load Calculation Formula + Examples

The method for determining the total electrical demand that a generator must supply involves a systematic approach to accounting for all connected loads. This calculation typically begins by identifying each individual electrical device or appliance intended to be powered by the generator, determining its power consumption in watts or kilowatts, and then summing these values. A crucial aspect of this process involves factoring in the demand factor and the diversity factor to account for the reality that not all loads will operate simultaneously at their maximum rated power. For instance, a building might have a total connected load of 100kW, but a demand factor of 0.8 suggests that the maximum anticipated load at any given time is only 80kW.
