Which article of the NEC would you consult for information on grounded conductors?

The correct choice for consulting information on grounded conductors is Article 200 of the NEC (National Electrical Code). This article specifically addresses various aspects related to grounded conductors, including their definitions, requirements, and installation practices.

Grounded conductors, often referred to as neutral conductors, are critical in electrical systems for establishing a reference point for grounding and ensuring safety. Article 200 ensures that these conductors are properly identified and utilized within electrical installations, outlining the necessary precautions and specifications. This information is essential for maintaining compliance with safety regulations and for the proper functioning of electrical systems.

While the other articles have their relevance to different topics within the NEC, they do not focus specifically on grounded conductors. Article 100 covers definitions and terminology, Article 225 pertains to outside feeders and branch circuits, and Article 510 relates to electrical requirements for hazardous locations. Therefore, for a detailed understanding of grounded conductors, Article 200 is the appropriate reference.
