Scope:

These requirements cover electrical rigid metal conduit – steel (ERMC-S), elbows, couplings, and 
nipples for use as a metal raceway for installation of wires and cables in accordance with CSA C22.1, 
Canadian Electrical Code, Part I, NOM-001-SEDE, Standard for Electrical Installations, and NFPA 70, 
National Electrical Code (see Reference Item No. 1, Annex A). ERMC-S is provided with a zinc, zinc-
based, nonmetallic, or other alternate corrosion-resistant exterior coating and an organic or zinc interior 
coating. It is the user's responsibility to determine the appropriate product for their application. 

1.2 Non-ferrous and stainless steel conduit are covered by the standards listed in Reference Item No. 2, 
Annex A. 

Project need:

To update the current standard due to user experience/feedback/new technology (new edition). This proposed New Edition is being developed at the request of CANENA THSC 23A MT1. It will provide the industry with updated requirements on steel electrical rigid metal conduits.
