Stranded conductors are defined as which of the following?

• A. Wire made of a number of smaller wire strands wrapped around each other
• B. A single solid wire
• C. A fiber optic strand
• D. A coaxial conductor

Answer: (A)

Stranded conductors are wires built from multiple smaller strands twisted together to form a single conductor. This design provides greater flexibility, which is important in alarm wiring where cables need to bend and navigate through tight spaces. The option describing a wire made of several smaller strands wrapped around each other matches this definition exactly. A solid wire is not stranded, a fiber optic strand is for light transmission rather than electrical current, and a coaxial conductor is a specific type of cable with shielding, not simply a bundle of strands.
