If No. 16 stranded wire is used on a power-limited system, what is the maximum number of strands permissible?

• A. 7 strands
• B. 8 strands
• C. 9 strands
• D. 10 strands

Answer: (A)

In power-limited circuits, terminations and lugs are designed to accommodate a specific strand count. For a No. 16 conductor, the standard limit is seven strands, which ensures the wire fits properly in the terminal and makes solid electrical contact. Using more strands can prevent a secure clamp, create loose strands, and lead to overheating or unreliable connections. Therefore, seven strands is the maximum permissible; eight or more would not be allowed, while six or fewer would still be acceptable but not maximizing the allowed count.
