What does Article 342 refer to in the National Electrical Code?

Article 342 in the National Electrical Code (NEC) specifically pertains to Intermediate Metal Conduit (IMC). IMC is a type of conduit that is used to protect and route electrical wiring in various installations. It is heavier than electrical metallic tubing (EMT) but lighter than rigid metal conduit (RMC), making it a preferred option in many applications due to its strength and resistance to corrosion while being easier to handle and install than RMC.

This article covers various aspects of IMC, including its purpose, installation methods, and standards related to its use, ensuring that electrical systems are safely and effectively protected. Understanding Article 342 is essential for ensuring compliance with NEC regulations in installations that involve intermediate metal conduit, promoting safety, reliability, and durability in electrical work.
