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

Step 1: Understanding the question.
The minimum vertical distance of a dwelling unit from high voltage electric lines is a safety standard aimed at reducing the risk of accidents and electrocution. These guidelines are issued by safety authorities to ensure public safety around power lines.

Step 2: Analyzing the options.
(A) 3.7: Correct — According to safety regulations, the minimum vertical distance from high voltage electric lines to any dwelling is typically 3.7 meters.
(B) 2.5: This distance is insufficient for high voltage power lines.
(C) 1.2: This distance is too small and does not meet the safety standards for high voltage electric lines.
(D) 4.2: This is higher than the required minimum, though it may be applicable in certain specific scenarios, the correct minimum is typically 3.7 meters.

Step 3: Conclusion.
The correct answer is (A) 3.7, which is the minimum vertical distance for safety around high voltage power lines.

Answer 2

Safety codes specify a minimum vertical clearance between a high-voltage line and the nearest point of any dwelling below it, to guard against arcing and accidental contact. Let's check each figure:

1. 3.7: This matches the minimum vertical clearance figure specified in the applicable safety regulations for a dwelling beneath a high-voltage line.
2. 2.5: This figure is smaller than the specified minimum, and would not provide the margin of safety the regulation requires.
3. 1.2: This figure is far too small for a high-voltage line clearance, it is closer to distances used for low-voltage or service lines.
4. 4.2: This figure is larger than the specified minimum, exceeding what the regulation actually requires as the floor value.

2.5 and 1.2 fall short of the safety margin required, and 4.2 overshoots the specified minimum, leaving 3.7 as the value the regulation actually sets.

Therefore, the correct answer is 3.7.
