Solid wire is generally cheaper and easier to terminate than stranded wire. Which statement best reflects this?

• A. True
• B. False
• C. Depends on the application
• D. Only for large gauge wires

Answer: (A)

Solid wire is generally cheaper and easier to terminate because it is a single, stiff conductor that fits cleanly into most terminal blocks used in alarm equipment. The termination process is straightforward: strip a short length and tighten the screw or clamp, and the solid conductor holds its shape without fraying. Stranded wire, while more flexible, requires extra care to terminate: the multiple strands can splay or fray, and often you need additional steps like twisting, tinning, or using ferrules or special connectors to ensure a secure, reliable connection. In typical alarm installations, these factors make solid wire the more cost-effective and easier-to-connect option. If routing flexibility is a priority, stranded wire has its use, but for straightforward terminations solid wire usually wins.
