Which calculation considers both the branch circuits and feeders?

The calculation that takes into account both branch circuits and feeders is the Service Load Calculation. This type of calculation is essential because it helps in determining the total electric load that will be served by the electrical service entrance. It encompasses the loads served by all the branch circuits and integrates the capacity and demands of the feeders connecting to those circuits.

By understanding the Service Load Calculation, you can ensure that the electrical service is adequately sized to handle the total expected load, which includes both continuous and non-continuous loads from various circuits. This approach is crucial for ensuring safety, compliance with code requirements, and the efficient operation of the electrical system.

The other options, while related to load calculations, do not encompass both branch circuits and feeders in the same way. Total Load Calculation focuses on the sum of all loads without specifically addressing their distribution through feeders. Demand Load Calculation emphasizes the anticipated maximum load that may be required, rather than detailing how that load is served. Active Load Calculation, while relevant in certain contexts, does not capture the full scope of both branch circuits and feeders. Therefore, the Service Load Calculation is the most comprehensive and appropriate method for this evaluation.
