What does the product description "10 - 19 SD CU THHN-THWN 2" indicate about the conductor?

• A. 10 AWG with 19 strands, hard copper conductor
• B. 10 AWG with 19 strands, soft copper conductor
• C. 8 AWG with 19 strands, soft copper conductor
• D. 10 AWG with 12 strands, soft copper conductor

Answer: (B)

The product description "10 - 19 SD CU THHN-THWN 2" specifies that the conductor is a 10 AWG (American Wire Gauge) size with 19 strands, indicating it is designed for flexibility and ease of handling due to its stranded construction. The use of "CU" in the description signifies that the conductor is made of copper. The designation "SD" further implies that it is a soft drawn conductor, meaning it is more ductile and malleable compared to hard drawn copper, making it suitable for various applications where bending and flexibility are necessary. Additionally, "THHN-THWN" refers to the type of insulation used for the conductor, which indicates it is suitable for both wet and dry locations, providing a layer of protection for the electrical wiring. Overall, the details in this product description align perfectly with choice B, confirming its accuracy.
