Conductors of what size and larger shall be stranded when installed in raceways?

Conductors of what size and larger shall be stranded when installed in raceways?

• A. 6 AWG
• B. 10 AWG
• C. 4 AWG
• D. 8 AWG

Answer: (D)

Stranded conductors are typically required for larger sizes due to their flexibility and ease of installation, especially in raceways where bending and maneuvering may be necessary. In this context, the correct size for conductors to be stranded when installed in raceways is 8 AWG. Using stranded conductors helps reduce the likelihood of damage when pulling the wire through bends and turns in a raceway system. This is particularly essential for larger conductors, as solid conductors can be more rigid and could break or become damaged during installation. Therefore, the industry standard mandates conductors of this gauge and larger to be stranded, influencing their performance and reliability in electrical applications. The other sizes listed in the choices do not follow the standard guidelines for stranding when installed in raceways, making them less suitable for ensuring the optimal functionality and flexibility required during installation.
