What is the minimum safe distance for voltages above 330kV?

• A. 3m
• B. 8m
• C. 6m
• D. 10m

Answer: (B)

Minimum safe distance from exposed energized parts rises with voltage to prevent arcing. For voltages above 330 kV, the established clearance is eight metres. This margin helps protect people and equipment from flashovers and electric shocks even under varying conditions like moisture or weather. In practice, keep the forklift, loads, and any conducting parts outside this zone; if proximity is unavoidable, de-energize or isolate the circuit or implement appropriate barriers and safe work procedures. The other distances don’t meet the standard for this voltage level: smaller clearances aren’t sufficient to prevent arcing, while a larger distance isn’t the required minimum in this context.
