Where should liquid-tight flexible metallic conduit NOT be used?

In dry locations
Where subject to physical damage
In low voltage applications
In permanent installations

The correct answer is: Where subject to physical damage

Liquid-tight flexible metallic conduit is specifically designed for environments where moisture and humidity may exist, providing protection for electrical conductors. However, it is crucial to understand the types of locations and situations where its use is appropriate. The conduit is not intended to be used where it is subject to physical damage. Applications involving potential mechanical impact require a more robust and protective conduit solution that can endure such conditions without compromising safety and reliability. Thus, in areas where physical damage is a concern, using alternative types of conduit, such as rigid metallic conduit (RMC) or intermediate metallic conduit (IMC), is advisable as they provide a higher level of protection against impacts and other physical threats. While liquid-tight flexible metallic conduit can be used in dry locations, low voltage applications, and permanent installations, the emphasis on avoiding areas prone to physical damage is critical for maintaining the integrity of electrical systems. Proper selection of conduit type based on environmental conditions and physical exposure is essential to ensure optimal performance and safety in electrical installations.
