Question #369
The safe distance between a mobile elevating work platform and the outermost conductors of power lines with a rated voltage from 1 to 15 kV is:
Bezpieczna odległość podestu od skrajnych przewodów linii elektroenergetycznych o napięciu znamionowym od 1 do 15 kV wynosi:
a
3 m
3m
b
15 m
15m
c
5 m
5m
Correct answer
d
20 m
20m
Why?
For this question, select at least 5 m horizontally from the outermost conductor (skrajny przewód). The precise regulatory range is above 1 kV up to and including 15 kV. The 3 m distance applies up to and including 1 kV, so the question states the lower boundary imprecisely.
