Spare or unused raceways shall be sealed with sealants ______ for use with the cable insulation, conductor, insulation, bare conductor, shield, or other components.

Spare or unused raceways must be sealed with sealants that are specifically identified for use with the various components contained within the raceway, including cable insulation, conductors, and other elements. This requirement ensures that the sealants are compatible with the materials present, which helps prevent degradation, insulation failure, or the introduction of harmful chemicals that could compromise the integrity of the electrical system.

Using sealants that are properly identified also supports compliance with safety standards and local codes, ensuring that installations are not only functional but also safe over their lifetime. Sealants that are simply labeled as "approved" may not necessarily meet the requirements for compatibility with specific materials, while "listed" typically refers to products that have been tested and certified for a particular purpose. Identified sealants specifically denote compatibility and suitability for use with electrical components, making them the most appropriate choice in this context.
