Wire and Cable - UL Code Authorities
PREFACE Each year, millions of feet of wire and Cable are installed in all types of buildings and are subjected to many different environmental conditions. Because of the choices available, it is important to know which wiring is suitable for a specific situation. It is also important to be able to properly identify these locations. Markings on or associated with the product, the UL Listing, Classification, or Verification information, and requirements in the current edition of the National Electrical Code all convey the information needed to ensure a compliant installation. This publication explains markings found on UL Certified, Listed, Classified, or Verified wire and Cable . UL has developed this guide for use by code Authorities , electric utilities, contractors, installers, users, designers, and other interested parties to aid in understanding the markings found on wire and Cable , and the applicable codes and standards in order to facilitate a reasonably safe and code-compliant installation.
When these assemblies use Recognized cable and are sent to a building site separately, instead of being supplied with the equipment, these cable assemblies may be identified as Listed Computer Interconnection Cable Assemblies (DVPJ). Similarly, for communication equipment, Listed Communication Cable Assemblies (DUNH) may be used. AWM
