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

The correct answer is Article 426, which specifically addresses requirements for Fixed Outdoor Electric Deicing and Snow-Melting Equipment. This article provides guidelines for the design, installation, and operation of systems intended to prevent ice formation and melting snow on outdoor surfaces, such as driveways, sidewalks, and roofs. The provisions within this article ensure that the equipment is safely installed and operated, thereby minimizing hazards associated with electrical installations exposed to the environmental conditions typical of outdoor installations.

Other articles listed do not pertain to deicing and snow-melting systems. For example, Article 422 deals with appliances, while Article 424 focuses on fixed electric heating equipment. Article 440 covers motors and motor circuits, which are not related to melting snow or preventing ice build-up. Each article has a specific focus, and understanding these distinctions is crucial for compliance with the NEC when it comes to electrical systems used for various applications.
