Is liquidtight flexible metal conduit suitable for use as an equipment grounding conductor for sizes 1 1/2 inches and larger if all conditions are met?

Liquidtight flexible metal conduit (LFMC) is generally not considered suitable for use as an equipment grounding conductor, particularly for sizes 1 1/2 inches and larger, even if certain conditions are met. This is primarily due to its construction and the nature of its application, which do not consistently provide an effective ground path.

Grounding conductors must meet specific conductivity and installation requirements to ensure safety and reliability. LFMC, while providing some level of physical protection for conductors, does not guarantee the necessary continuity and capacity needed for effective grounding. The conduit itself is designed for flexibility and environmental protection rather than for grounding purposes.

In certain applications, while flexible metallic conduits can provide grounding capabilities, they must meet strict requirements that would often render them inappropriate for grounding when considering their flexibility and the potential for movement or vibration that could interrupt the ground continuity. Therefore, the assertion that LFMC is suitable for use as an equipment grounding conductor is inaccurate, leading to the conclusion that the answer is indeed false.
