What is the definition of LFMC in the context of raceways?

• A. A circular raceway with a rigid design
• B. A raceway with a liquidtight, nonmetallic jacket
• C. A flexible metal raceway with a sunlight-resistant jacket
• D. A rigid conduit for underground installation

Answer: (B)

The definition of LFMC, or Liquidtight Flexible Metal Conduit, emphasizes its construction and purpose in electrical installations. LFMC is specifically designed to be a raceway that features a liquidtight, nonmetallic jacket, which makes it ideal for environments where protection from moisture and liquids is essential. This protective jacket allows the conduit to be used in various applications, including those where flexibility and environmental protection are required. In contrast, other options describe different types of raceways that do not accurately reflect the characteristics of LFMC. For example, a circular raceway with a rigid design does not accommodate the flexible nature of LFMC. Similarly, while there are raceways with sunlight-resistant jackets, the specific feature of being liquidtight and having a nonmetallic jacket distinguishes LFMC from flexible metal options. Lastly, a rigid conduit for underground installation does not align with the flexibility aspect inherent in LFMC. Thus, the defining feature of LFMC being a raceway with a liquidtight, nonmetallic jacket is what makes it the correct answer in this context.
