Are spliced or reinsulated conductors allowed in a cellular metal floor raceway when an outlet is abandoned on loop wiring?

The correct answer indicates that spliced or reinsulated conductors are not allowed in a cellular metal floor raceway when an outlet on loop wiring is abandoned. This aligns with established safety standards and practices in electrical installation, ensuring that any conductors remain securely and correctly insulated to prevent hazards such as electrical shorts, exposures, or other safety risks that can arise from abandoned wiring.

Cellular metal floor raceways are designed to provide a safe, organized pathway for electrical wiring while providing protection from physical damage. When an outlet is abandoned, any splices or reinsulated sections can introduce risks, as they may not be adequately supported or monitored. Proper practices dictate that any wiring not in use should be removed or terminated correctly to maintain the integrity and safety of the installation according to the electrical code.

This prohibition is also reinforced by specific codes that govern wiring methods, reinforcing that all conductors within a raceway must be current-carrying and properly insulated to ensure compliance and safety.
