Which article focuses on the use and safety of storage batteries?

Article 480 of the National Electrical Code (NEC) specifically addresses the use and safety of storage batteries. This article outlines the requirements for the installation, maintenance, and operation of battery systems to ensure safety and reliability. It provides guidelines on aspects such as the proper installation of various types of batteries, the management of hydrogen gas emissions, overcurrent protection, and ventilation needs to prevent hazardous situations.

Understanding Article 480 is essential for electricians and engineers working with battery systems because it helps them to create installations that are not only compliant with the NEC but also safe for users and the surrounding environment. The focus on safety is critical, given the potential hazards associated with battery storage, including electric shock, fire, and chemical exposure.

The other articles mentioned do not pertain to storage batteries; for example, Article 470 deals with power conversion equipment, Article 490 addresses the grounding and bonding of equipment, and Article 500 focuses on hazardous locations. By recognizing the specific focus of Article 480, professionals can ensure they follow the correct guidelines for battery safety and compliance.
