Where in the NEC would you find information regarding switchboards and panelboards?

The National Electrical Code (NEC) contains various articles that cover specific topics related to electrical installations. In the context of switchboards and panelboards, Article 408 is the relevant section. This article provides guidelines, definitions, and requirements regarding the installation of panelboards and switchboards, which are crucial for managing electrical circuits and distributing power safely within a building or facility.

Panelboards are typically used to divide electrical power into subsidiary circuits, while switchboards serve a similar purpose but are usually larger and can handle higher voltage and current. Article 408 addresses aspects such as the construction, installation, accessibility, and maintenance of these devices, ensuring they are safely integrated into electrical systems.

Understanding Article 408's content is essential for electricians to ensure they adhere to safety standards and code requirements when installing or maintaining switchboards and panelboards. This knowledge helps prevent electrical hazards and ensures system efficiency and reliability.
