Note: This NOI (originally published on August 3, 2022) was reissued by the responsible SDO on July 23, 2024. 

 

Note: As requested by the responsible SDO, this NOI being reissued as the standard was in the initial stages of development for more than 12 months. An additional comment period of August 22 to September 13, 2023 (originally published on August 3, 2022).

 

1.1 These requirements cover steel electrical intermediate metal conduit (IMC), nipples, elbows, and couplings. This conduit is provided in trade sizes 1/2 – 4 (16 – 103), for use as a metal raceway for the installation of wires and cables in accordance with the National Electrical Code (NEC), NFPA 70. The values in parentheses are metric designators of conduit.

1.2 Steel intermediate metal conduit is provided both internally and externally with an acceptable level of corrosion resistance in normally corrosive environments. Reference 6.1 for details regarding protective coatings.

Project need:

To support innovation in the field of Wiring Products by providing requirements for the construction/installation/use of Intermediate Metal Conduit in the Canadian context. This proposed New Standard is being developed at the request of Industry, regulators, and Certification agencies. It will provide the industry with updated references and requirements based on current best practices.
