How would you describe the conductor with the product description of 10 - 19 SD CU THHNTHWN 2?

The designation "10 - 19 SD CU THHNTHWN 2" refers to a specific type of electrical conductor. The "10" indicates that this conductor is 10 AWG (American Wire Gauge), which is a measure of the wire's thickness. The term "19" signifies that the conductor has 19 strands and "SD" suggests that it is a stranded conductor.

The abbreviation "CU" stands for copper, indicating the material of which the conductor is made. The "THHN/THWN" notation refers to the insulation type; THHN (Thermoplastic Heat and Water Resistant Nylon-coated) and THWN (Thermoplastic Heat and Water-resistant) are commonly used in a variety of electrical installations. The number "2" may suggest that it is rated for use in certain conditions or applications, which is typical for conductors.

Given this information, the correct choice describes a 10 AWG conductor that is made of copper with a stranded construction consisting of 19 strands, which aligns with the product description provided. This interpretation helps in understanding the properties of the conductor, including its flexibility and suitability for electrical applications.
