Article 426 addresses which of the following systems?

Article 426 specifically addresses Fixed Outdoor Electric Deicing and Snow-Melting Equipment. This article lays out the requirements and guidelines for systems designed to prevent the accumulation of snow and ice on outdoor surfaces, enhancing safety and functionality. Such systems are crucial for maintaining accessibility in cold climates, especially in areas like walkways, driveways, and roofs.

The focus on these systems includes aspects such as installation, maintenance, and safety protocols that ensure effective operation while preventing hazards associated with electrical installations in potentially wet and icy conditions. The requirements help ensure that the equipment used is both efficient at melting snow and ice and safe for human interaction and the environment.
