What type of conductors are preferred for making terminations, splices, or taps within a raceway?

The preferred type of conductors for making terminations, splices, or taps within a raceway is metal. Metal conductors, such as copper and aluminum, are favored for these applications due to their excellent electrical conductivity, which ensures minimal resistance and optimal performance. Metal conductors are also typically more durable and better suited for maintaining reliable connections over time, especially in environments where physical stresses could occur.

Using metal conductors allows for better heat dissipation, which is critical in preventing overheating during operation. Additionally, metal conductors provide superior mechanical strength and can withstand the stresses that may be exerted during installation and use, making them more reliable compared to other conductor types.

While other materials like aluminum may be used in specific situations, metal conductors as a category remain the most common and universally accepted standard for terminations and splices within raceways.
