Which Article of the NEC outlines the support requirements for RMC?

The National Electrical Code (NEC) outlines the support requirements for rigid metal conduit (RMC) in Article 344. This article provides specific details regarding the installation, support, and securing of RMC to ensure safety and effectiveness in electrical installations.

RMC is a type of conduit that is often used for protection and support of electrical conductors. Proper support is crucial to maintain its integrity and to prevent issues related to sagging or mechanical damage, which can diminish the conduit’s effectiveness. Article 344 addresses the necessary spacing, types of supports, and installation guidelines for RMC to ensure compliance with safety standards.

In addition, while there are other articles in the NEC that deal with different types of conduit, such as Article 358 for EMT (Electrical Metallic Tubing) and Article 352 for non-metallic conduit, they pertain specifically to their respective conduit types. Thus, for RMC support requirements, Article 344 is the appropriate and relevant section.
