When is it necessary to use liquid-tight flexible conduit?

Using liquid-tight flexible conduit is essential in situations where the conduit may be exposed to moisture or where the environment is likely to be wet. This type of conduit is specifically designed to prevent moisture ingress, which is critical in safeguarding the electrical components and ensuring their reliable operation. Liquid-tight flexible conduit creates a barrier that protects against water penetration, making it suitable for use in locations such as pools, kitchens, and outdoor installations where exposure to the elements is a concern.

In contrast, other applications of flexible conduit may not require such robust moisture protection. While outdoor applications may often benefit from liquid-tight options, moisture exposure can also occur in indoor settings, which is why using this type of conduit in damp areas is crucial regardless of whether the installation is outdoor or indoor. Additionally, using liquid-tight flexible conduit is not necessary for all installations, particularly in dry or non-moisture-prone environments where standard conduit may suffice. High-temperature environments require specific conduit types, but this does not inherently correlate with moisture exposure.
