Question: Q) How can I tell if a cable is listed for use in wet locations?I am trying to specify a PLTC/ITC twisted, shielded pair cable (and a 3C/shielded) - 18AWG or 20AWG, which is listed for use in wet locations. (It will be run in conduit underground and in conduit exposed to the weather in a chemical plant).The manufacturer keeps directing me to their catalog where it says things like "suitable for direct burial" (for some cables) and "moisture resistant" (for others). I would think that a UL listing would be something the manufacturer would be able to point to rather easily and definitively... if they make such a product and aren't just trying to snowball me.
Verifying Cable Listing for Wet Locations
1. Check for UL Listing
Look for cables that are listed by Underwriters Laboratories (UL) as "Suitable for Use in Wet Locations." The UL listing should be printed on the cable jacket or in the manufacturer's specifications. Search the UL website (https://uldatabase.ul.com/) using the cable manufacturer and model number to verify the listing.
2. Look for "Water-Resistant" or "Moisture-Resistant" Labels
Some manufacturers use these terms to indicate that the cable is suitable for use in wet locations. While these labels are not as definitive as a UL listing, they can provide an indication that the cable is designed for moisture resistance.
3. Review the Manufacturer's Specifications
Carefully examine the manufacturer's catalog, website, and technical data sheets for information on the cable's suitability for wet locations. Look for phrases such as "direct burial," "outdoor use," or "weatherproof."
4. Contact the Manufacturer
If you cannot find clear information on the cable's wet location listing, contact the manufacturer directly. Ask them to provide a written statement confirming that the cable is UL listed for use in wet locations.
Additional Considerations: Consider the specific conditions of the chemical plant environment. Ensure that the cable is suitable for use with the chemicals and potential corrosive agents present. Proper installation methods, such as using waterproof conduit and connectors, are also crucial for protecting the cable from moisture. Flag for review
