Exterior raceways shall be drained and shall be listed and labeled for use in wet locations. Which term describes the approval status required for exterior raceways used in wet locations?

• A. Listed and labeled
• B. Rated for outdoor use
• C. Waterproof
• D. Tested

Answer: (A)

The requirement hinges on having formal verification from a recognized testing laboratory. Exterior raceways used in wet locations must be both listed and labeled. “Listed” means the product has been evaluated and found to meet applicable standards. “Labeled” means the product carries a label showing the listing and the intended use, including suitability for wet locations. This combination provides the NEC assurance that the raceway is not only capable of outdoor exposure but has been specifically approved for wet-location installation. Being “rated for outdoor use” is just a general environmental rating and doesn’t guarantee the formal listing and labeling for wet locations. “Waterproof” describes a property, not the certification status, and “tested” alone does not imply the product is officially listed and labeled for use in wet locations.
