What information is typically included in a load calculation for electrical service?

The load calculation for electrical service is a crucial step in ensuring that the electrical system is designed to accommodate the needs of the connected devices safely and efficiently. The inclusion of continuous vs. non-continuous loads, total demand, and diversity factors in this calculation is essential for several reasons.

Continuous and non-continuous loads help determine how much energy will be used over time. Continuous loads are those that are expected to run for three hours or more, while non-continuous loads operate for shorter periods. This distinction is vital because it influences the sizing of the electrical components, such as circuit conductors and breakers, to ensure they can handle the necessary load without risk of overheating or failure.

The total demand is calculated to see how much load the electrical system will need to supply at peak times, allowing for proper sizing of transformers and service entrance equipment. It ensures that the system can provide adequate power without tripping circuits or causing damage.

Diversity factors consider the fact that not all circuits will be under maximum load at the same time. By accounting for this, a more accurate and efficient plan can be formed, potentially reducing costs by avoiding over-sizing the system components.

This comprehensive approach, focusing on load types and demand, ensures that the electrical service design
