Aircraft hangars are addressed in which article of the NEC?

Aircraft hangars are specifically addressed in Article 513 of the National Electrical Code (NEC). This article outlines the requirements for electrical installations in aircraft hangars to ensure safety and compliance with regulations. It covers various aspects such as wiring methods, equipment requirements, and special considerations for hazardous locations due to the presence of fuel and volatile substances often found in hangars.

Understanding the focus of Article 513 is crucial for ensuring that electrical systems in these environments are both safe and functional. The article provides guidelines tailored to the unique hazards and operational needs of aircraft hangars, including provisions related to lighting, grounding, and emergency systems.

The other articles listed do not pertain directly to the specific topic of aircraft hangars; hence they do not provide the framework needed for such installations. It's important to familiarize oneself with these distinctions when working with the NEC, as choosing the correct article ensures compliance and enhances safety in specific electrical applications.
