What should be included in a residential load calculation?

In a residential load calculation, it is essential to consider both general loads and individual loads to ensure an accurate assessment of the electrical demand for the home. General loads include items like lighting, receptacles, and general purpose circuits that are consistently utilized throughout the house. Individual loads, on the other hand, refer to specific equipment that may have considerable power requirements, such as HVAC systems, major appliances, and other specialized electrical devices.

By incorporating both categories, the load calculation effectively captures the total electrical demand, allowing for proper sizing of feeders, service equipment, and panelboards. This ensures that the electrical system can handle the diverse range of usages without overloading, thereby enhancing safety and efficiency. A comprehensive approach to load calculation helps in preventing issues like voltage drops or circuit overloads, which can lead to system failures or electrical hazards.
