An electrical conduit serves as a raceway that offers a protective pathway for electrical wires and cables in any environment. With a wide variety of electrical conduits available, selecting the right one based on your specific application’s needs is crucial.
Although manufacturers often recommend which type of conduit to use, this blog will focus on the various applications for liquid-tight flexible metal conduit. These include wet or moist environments, areas exposed to corrosive elements, settings prone to dust and dirt, and various outdoor environments.
Wet and Moist Environments
Liquid-tight conduit and fittings are specifically designed to protect wires and cables from liquid and moisture. These conduits are ideal for humid, damp, or wet environments where cabling is necessary. Prime examples include car washes, water management facilities, and food and beverage processing plants that regularly hose down equipment. Using liquid-tight conduit ensures public and employee safety, extends the lifespan of cables, and prevents electrical failures.
When Cables May Be Exposed to Corrosive Elements
Liquid tight conduit is also an optimal choice for environments that are often exposed to corrosive elements. This type of conduit is not only capable of keeping out moisture, but it is also effective at sealing out harmful substances that can deteriorate wires and cables. This is highly beneficial for applications such as HVAC units, chemical facilities and other areas that are prone to corrosive substances.
Various External Applications
Electrical installations exposed to outdoor elements can encounter various problems. UV rays, extreme temperatures, moisture, and other factors can cause breakage and damage. Using liquid-tight flexible metal conduit protects cables and wires from these hazards, extending their lifespan and preventing damage.
Dirty or Dusty Areas
Dirt, dust, and other tiny particles can cause short circuits and equipment malfunctions when wires and connections are not protected. In agricultural operations, textile plants, wood, pulp, and paper mills, and similar settings, a sealed, liquid-tight conduit can guard against dust and particulate infiltration.
An additional benefit of flexible metal conduit is its ability to bend. Unlike rigid conduit, flexible metal conduit bends easily, making it ideal for applications where rigid conduit would be challenging to install.
Choosing the Right Liquid-Tight Conduit
When selecting a liquid-tight conduit for a specific application, several factors need to be considered:
Material and Flexibility
Metal vs. Non-Metal: Choose LFMC for applications requiring extra mechanical strength and LFNC for environments where corrosion resistance is paramount.
Bend Radius: Ensure the conduit can be easily routed through the installation path without excessive bending.
Temperature Rating
Different liquid-tight conduits are rated for various temperature ranges. It is crucial to select a conduit that can withstand the environmental temperatures it will be exposed to, ensuring it maintains its integrity and flexibility.
Compliance and Standards
Ensure that the liquid-tight conduit meets the relevant industry standards and codes, such as UL (Underwriters Laboratories) listings and NEC (National Electrical Code) requirements. Compliance guarantees the conduit is tested and approved for safety and reliability.
Conclusion
Liquid-tight conduit is an essential component in ensuring the safety and durability of electrical systems in a variety of challenging environments. Its ability to protect against moisture, corrosion, and physical damage makes it indispensable in outdoor, wet, industrial, underground, and marine applications. By selecting the right type of conduit and following best practices in installation, you can significantly enhance the reliability and lifespan of your electrical installations.
