NECA Releases Revised Standard for Installing Steel Conduits (RMC, IMC, EMT)
The National Electrical Contractors Association (NECA) is excited and proud to announce the publishing of its revised standard NECA 101 – 2020, Standard for Installing Steel Conduits (RMC, IMC, EMT). This revised ANSI-approved standard describes installation procedures for steel rigid metal conduit (RMC), steel intermediate metal conduit (IMC), and steel electrical metallic tubing (EMT), including steel conduits with a supplementary PVC coating, used as raceway systems for electrical wiring in residential, commercial, and industrial occupancies. This Standard also includes information on fittings and other applicable accessories necessary for a quality installation of these raceways.
NECA 101 drills down into installation details not found in the NEC, such as threading techniques, recommended securement processes that compensate for thermal expansion and contraction, bending processes and protection from electromagnetic interference (EMI). Because workmanship is described in this standard, it does recommend use of specific tools to accomplish complete installations. Specific techniques must be used when threading PVC-coated rigid conduit. This must be performed in a manner that the coating remains intact and undamaged. Multiple quality workmanship installation methods and techniques are provided to assist not only seasoned electrical workers, but also those learning the electrical trade.
“NECA’s National Electrical Installation Standards (NEIS®) are the only quality and performance standards for electrical construction. The NEIS collection has grown, and as new technologies emerge, the NEIS evolve and keep pace,” said Michael Johnston, NECA’s executive director of standards and safety. Johnston also emphasizes that “the standards are constantly evolving and providing significant value to those in the electrical designing and engineering communities. The NEIS help professionals in developing design specifications in that they reduce and often eliminate specification writing time.” The NEIS are often used by electrical contractors, consulting engineers, facility managers, and other professionals who design and specify for electrical construction projects. With their installation detail, illustrations and thorough explanations, the NEIS are a valuable training tool for electrical industry. In fact, NECA 101 is a valuable reference included in the Energy Storage and Micro-grid Training and Certification (ESAMTAC).
