For a high-voltage transformer installation, how many strands of barbed wire are required on top after extending the fence by 1 foot?

• A. 2
• B. 3
• C. 4
• D. No minimum required

Answer: (B)

High-voltage transformer sites are fenced with multiple strands of barbed wire at the top to deter climbing and reduce the chance of someone making contact with energized equipment. The standard practice is to have three strands of barbed wire along the top as the minimum barrier for such facilities. Extending the fence by one foot does not remove this requirement; the top barrier needs to be structured with at least three strands to maintain an adequate deterrent. Two strands would be easier to overcome, while four would be more than the minimum for this scenario. So, after the extension, three strands are required.
