Organization: NEMA
Publication Date: 1 January 2020
Status: active
Page Count: 17
scope:

This Standard covers the requirements for steel electrical metallic tubing for use as a raceway for wires or cables of an electrical system. Finished tubing is typically furnished in Standard 10-ft (3.05-m) lengths. The production of lengths shorter or longer than the Standard length shall be allowed. EMT is protected on the exterior surface with a metallic zinc coating or alternate corrosion protection coating (see UL 797 for alternate corrosion protection coating requirements) and on the interior surface with zinc or organic coating.

This Standard also covers electrical metallic tubing elbows.

Properly assembled systems of EMT-S, manufactured in accordance with this Standard, and other identified fitting provide for the electrical continuity required of an equipment grounding conductor.
