The National Electrical Contractors Association (NECA), Bethesda, Md., has published the tenth volume of its growing series of National Electrical Installation Standards. NECA 101-2001, “Standard for Installing Steel Conduits,” describes installation procedures for three common types of tubular steel raceways: rigid metal conduit, intermediate metal conduit, and electrical metallic tubing.

Procedures described in the standard include threading and bending steel conduits and special considerations for installing PVC-coated steel conduit. The standard also contains an appendix dealing with the use of steel conduits as grounding electrode conductors for electrical feeders and branch circuits.

NECA 101-2001 was developed in partnership with the Steel Tubing Institute of North America, based in Mentor, Ohio.
