How is the demand load determined when the average kW exceeds 12 kW?

The determination of demand load when the average kW exceeds 12 kW involves a specific calculation to ensure that the load is accurately represented for the purpose of electrical service sizing and planning. The correct approach is to multiply the average load by 1.05 for each kW above the threshold of 12. This method acknowledges that higher loads typically require more careful consideration to ensure that they are adequately supported without exceeding the capacity of the service infrastructure.

When the average load surpasses a certain limit, utilities and electricians apply this increased factor to account for peak demand and the potential for load changes, ensuring that the electrical system can handle unexpected surges in demand without compromising safety or performance. This methodology reflects common practices in electrical systems design, aligning with industry standards for reliable power delivery and management.

Choices like averaging the total kW or simply adding percentages do not accurately capture the nuances involved in calculating demand loads above the defined threshold. They either oversimplify the approach or fail to reflect the need for precise scaling in relation to actual load conditions.
