Article 314 covers which types of boxes?

Article 314 of the National Electrical Code addresses the requirements for outlet, device, pull, and junction boxes. These boxes play a critical role in electrical installations as they provide a safe enclosure for wire connections, protect the wires from damage, and support devices such as switches and outlets. The standard details specifications for various aspects including size, installation, and spacing of boxes, ensuring they meet safety and operational standards.

While other options include components relevant to electrical installations, they fall under different articles of the NEC. For instance, meter socket enclosures are covered under a different section focused on service-entrance equipment, while surge arresters and armored cable assemblies are also addressed in specific NEC articles. Therefore, the focus of Article 314 on outlet, device, pull, and junction boxes is central to ensuring safe and effective electrical distribution in various applications.
