What does the Type FMT refer to in conduit classifications?

Type FMT refers to Flexible Metallic Tubing, which is designed specifically for use in various electrical applications where flexibility and protection of conductors are required. This type of conduit is made from thin-walled metallic materials and is particularly useful in areas where wiring needs to navigate around corners or where frequent adjustments are necessary.

Flexible Metallic Tubing is appreciated for its ability to withstand environmental hazards and is often used in commercial and industrial settings. Its lightweight nature, combined with the ability to offer a degree of mechanical protection, makes it a preferred choice for certain installations.

The others listed—Reinforced Thermosetting Resin Conduit, Liquidtight Flexible Metal Conduit, and Electrical Nonmetallic Tubing—refer to different types of conduits that serve specific purposes but are distinct from FMT in terms of material composition, protection levels, or application areas. For instance, liquidtight conduit is specifically designed for environments where moisture protection is critical, while thermosetting resin conduit is used for certain chemical resistance applications.
