What type of equipment is specifically addressed in Article 408?

Article 408 of the National Electrical Code (NEC) specifically addresses the requirements and regulations for switchboards and panelboards. These are critical components of electrical systems that distribute electrical power to various circuits throughout a building or facility.

Switchboards are large assemblies that provide a centralized point for controlling electrical power distribution, while panelboards are used for distributing power and lighting circuits within a residential or commercial setting. The NEC outlines specifications for their construction, installation, maintenance, and safe operation to ensure safety and reliability in electrical systems.

Understanding the distinct standards and guidelines for these types of equipment is crucial for electricians and electrical engineers, as they help ensure compliance with safety protocols, reduce the risk of electrical hazards, and facilitate effective operation within electrical infrastructures.
