Is flexible metal conduit (FMC) permitted for use in wet locations?

Flexible metal conduit (FMC) is not permitted for use in wet locations due to the potential for water to penetrate the conduit, which could lead to electrical hazards. FMC typically lacks the necessary sealing and protective characteristics required to safeguard the conductors from moisture and water exposure. In wet locations, it is crucial to utilize conduit that is specifically designed to withstand those conditions, such as rigid metal conduit or non-metallic conduits that have proper ratings for wet environments.

While there may be instances where FMC can be suitable for certain specific applications, these generally do not extend to wet locations where there is a constant risk of moisture ingress. The prohibition on FMC in wet locales emphasizes the importance of adhering to electrical codes and standards that maintain safety and ensure the integrity of the electrical systems installed in such environments.
