Which article addresses Fixed Outdoor Electric Deicing and Snow-Melting Equipment?

The correct answer is found in Article 426 of the National Electrical Code (NEC), which specifically focuses on the requirements for fixed outdoor electric deicing and snow-melting equipment. This article establishes the necessary provisions to ensure safety and proper installation for systems intended to prevent ice formation or to melt snow on surfaces like sidewalks, driveways, and roofs.

Article 426 outlines key aspects such as the types of equipment allowed, installation methods, and associated performance criteria. By addressing these specifications, the article helps to mitigate hazards related to electric shock, fire, or equipment malfunction in environments exposed to weather conditions that lead to ice and snow accumulation.

In contrast, other articles deal with different topics: Article 422 pertains to appliances, Article 424 covers fixed heating equipment, and Article 440 deals with motor circuits. Understanding the distinctions between these articles is essential for compliance with the NEC and effective application in electrical installations.
