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

Article 342 of the National Electrical Code specifically addresses Intermediate Metal Conduit (IMC). IMC is a type of conduit that is more lightweight compared to rigid metal conduit while still offering a certain degree of strength and integrity for electrical installations.

IMC is designed to provide mechanical protection for conductors and cables within, offering better corrosion resistance due to its protective coatings. It is typically used in a variety of applications, particularly where environmental conditions call for a more resilient type of conduit that is easy to handle and install.

Understanding the specific applications and advantages of IMC under Article 342 helps electricians and engineers ensure compliance with electrical installations, providing safety and adherence to best practices outlined in the NEC.
