What factor is used when calculating the remainder load above 3,000 VA?

In the context of load calculations, particularly when determining the remainder load above a certain threshold, the correct factor is crucial for accurate sizing of feeders and services. When calculating loads beyond 3,000 VA, using a factor of 35% allows for a more realistic assessment of the load that will actually be connected and used.

This percentage reflects an understanding of diversity in loads; not all connected devices will draw their maximum load simultaneously. Therefore, the 35% figure provides a balance that acknowledges some degree of variability and potential for not all loads to be on at the same time, ensuring that the system is not overly oversized, which would be inefficient and costly.

By applying this factor in calculations, you're able to derive a more practical and effective load management strategy, aligning with standard practices in the electrical industry. This approach ensures compliance with codes and standards that aim to optimize the performance and safety of electrical systems.
