What aspect does Article 220 specifically address regarding branch circuits?

Article 220 specifically addresses load calculations related to branch circuits. This article outlines the necessary procedures and formulas for determining the load that branch circuits must be able to carry safely and efficiently. Understanding load calculations is crucial for ensuring that circuits are properly designed to handle the expected electrical demand without risk of overload.

By following the guidelines set forth in Article 220, electrical contractors can accurately assess the total loads that will be imposed on various branch circuits in different lighting, appliance, and equipment scenarios. This helps ensure compliance with national standards and enhances safety within electrical systems.

While feeder sizing, wiring methods, and safety regulations are essential components of electrical work, they are covered in other areas of the National Electrical Code (NEC). Article 220 focuses specifically on how to calculate the loads for branch circuits, making it essential for the design and installation of safe and effective electrical systems.
