What is the difference between IMC and EMT conduit?

Intermediate metal conduit (IMC) is a steel tubing heavier than EMT but lighter than RMC. … Electrical metallic tubing (EMT), sometimes called thin-wall, is commonly used instead of galvanized rigid conduit (GRC), as it is less costly and lighter than GRC.

Is EMT the same as IMC?

EMT is commonly used for branch circuit wiring in homes (where the wiring runs are exposed) and in commercial buildings. … In residential wiring, IMC is usually limited to service entrance assemblies and exposed runs to and from exterior service panels. Otherwise, EMT is the standard for household installations.

What is the difference between EMT IMC and rigid conduit?

Rigid is a thick wall conduit that is normally threaded. EMT is a thin wall conduit that is not thick enough to be threaded. Electrical Metallic Tubing—EMT EMT is also called “thin-wall” conduit because it is thin and lightweight, especially compared to RMC.

Where can I use EMT conduit?

EMT conduit is more affordable than IMC or GRC, but its thin walls are more easily punctured. It is most often used in dry interior spaces, but it can be used in damp locations with corrosion-resistant hardware and rain-tight fittings.

Can you install EMT in a wet location?

EMT can be used in wet locations as long as the conduit is galvanized and you use all fittings that are identified for wet locations and protected from corrosion. EMT can be used in concrete as long as the fittings are identified for use. 358.10 Uses Permitted.
