Description / Abstract:

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 nominal 10-ft (3.05-m) lengths. It 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 a 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 fittings provide for the electrical continuity required of an equipment grounding conductor.
