What is the designation for Liquidtight Flexible Metal Conduit?

• A. Type PVC
• B. Type LFMC
• C. Type EMT
• D. Type FMT

Answer: (B)

Liquidtight Flexible Metal Conduit is designated as Type LFMC. This designation is crucial because it differentiates this specific type of conduit from others within the National Electrical Code (NEC) standards. LFMC is designed to provide a means of raceway that is flexible, resilient to moisture and chemicals, and suitable for use in environments where movement is anticipated, such as in connection with motors or other machinery. Understanding this designation helps electricians select the correct conduit type for various applications based on their durability, flexibility, and environmental resistance. In contrast, the other choices represent different types of conduits: Type PVC refers to polyvinyl chloride non-metallic conduits, Type EMT refers to Electrical Metallic Tubing, which is usually rigid and metallic but not flexible, and Type FMT refers to Flexible Metal Tubing, which does not have the same moisture-resistant properties as LFMC.
