Question

Minimum vertical distance of any dwelling unit from high voltage electric line is

• A. 3.7
• B. 2.5
• C. 1.2
• D. 4.2

Hint:

Always adhere to safety guidelines regarding the distance from power lines to ensure safety in construction and planning.

Answer 1

The Correct Option is A

Safety regulations fix a minimum vertical clearance between a high-voltage line and any dwelling beneath it.
1.2 and 2.5 are too small to provide an adequate safety margin, and 4.2 is larger than the actual specified minimum.
The figure the regulation sets as the minimum is 3.7.
So, the correct answer is 3.7.

Answer 2

Instead of recalling the exact figure directly, it helps to rank the four numbers from smallest to largest and reason about which one plausibly represents a strict safety floor rather than a looser guideline:

1. 1.2: The smallest figure, too tight a clearance to be a safe minimum for high-voltage lines specifically.
2. 2.5: Larger, but still below the safety floor set for high-voltage clearance in the applicable regulation.
3. 3.7: The figure that matches the minimum clearance floor set by the applicable safety regulation for dwellings beneath high-voltage lines.
4. 4.2: The largest figure, above the strict minimum the regulation actually requires.

Ranking the values and matching them against the safety floor set by the regulation points to the same figure.

Therefore, the correct answer is 3.7.
