Liquidtight flexible nonmetallic conduit is subject to which of the following limitations?

Liquidtight flexible nonmetallic conduit (LFNC) is designed for a variety of applications, but it does have certain limitations that should be considered during installation and use.

One significant limitation is its performance in direct sunlight. Exposure to ultraviolet (UV) rays can degrade the material over time, leading to brittleness and potential failure of the conduit. This means it is generally advisable to avoid using LFNC in applications where it will be directly exposed to sunlight for prolonged periods unless it is specifically rated for UV exposure.

Additionally, LFNC can also become brittle at extremely cold temperatures. The material used in LFNC may lose its flexibility and become rigid, which can lead to cracking or breaking under mechanical stress in cold environments.

Therefore, both limitations—vulnerability to UV light and brittleness in low temperatures—are critical considerations when selecting and installing liquidtight flexible nonmetallic conduit. Recognizing these limitations ensures that the conduit will function safely and effectively within its intended environment.
