Article 280 pertains to what kind of electrical components?

Article 280 of the National Electrical Code (NEC) specifically addresses surge arresters, which are devices designed to protect electrical equipment from voltage spikes. These transient overvoltages can arise from various sources, including lightning strikes and switching operations. Surge arresters function by diverting excess voltage away from sensitive equipment, thus preventing damage and ensuring the safe operation of electrical systems.

Understanding the role of surge arresters is crucial for electricians, particularly in environments where equipment is vulnerable to electrical surges. Knowledge of Article 280 helps electricians determine proper installation practices and the types of surge protection that are required for specific applications.

Other choices, while relevant to electrical systems, fall under different articles in the NEC. Cabinets and cutout boxes, junction boxes, and integrated gas spacer cable refer to other types of electrical hardware and installations, but they do not fall under the purview of Article 280. Each of these components is covered by its own set of NEC regulations, outlining different standards and requirements for their installation, use, and maintenance.
