What does the Type FMT refer to in conduit classifications?

• A. Flexible Metallic Tubing
• B. Reinforced Thermosetting Resin Conduit
• C. Liquidtight Flexible Metal Conduit
• D. Electrical Nonmetallic Tubing

Answer: (A)

Type FMT refers to Flexible Metallic Tubing. This type of conduit is specifically designed to provide a lightweight, flexible option for wiring in various applications. It is made from thin-wall, flexible metal and is used primarily in areas where there may be some movement of equipment or where rigid conduit might be too cumbersome. Flexible Metallic Tubing is particularly advantageous for its ability to be bent and shaped to fit around obstacles, making installation simpler and faster in complex environments. It also offers a degree of protection against physical damage to the conductors contained within. The metallic nature of FMT helps to shield the conductors from electromagnetic interference, a common concern in electrical installations. In contrast, other conduit types mentioned serve different purposes, such as Liquidtight Flexible Metal Conduit, which is designed for moisture and corrosion protection, or Electrical Nonmetallic Tubing, which is better suited for dry environments where additional flexibility is needed without the concerns of moisture or metal corrosion. Each conduit type has its distinct applications and benefits, aligning with specific installation needs and environmental considerations.
