Minimum clearances from power lines for electric animal
fences
Power line voltage
≤1000 V
>1000 V to ≤33,000 V
>33,000 V
If connecting leads and electric animal fence wires are
installed near an overhead power line, their height above
the ground shall not exceed 3 m (10'). This height applies
to either side of the orthogonal projection of the outermost
conductors of the power line on the ground surface, for a
distance of:
2 m (6'6") for power lines operating at a nominal
•
voltage not exceeding 1000 V.
15 m (50') for power lines operating at a nominal
•
voltage exceeding 1000 V.
Electric animal fences intended for deterring birds,
household pet containment or training animals such as
cows need only be supplied from low output energizers to
obtain satisfactory and safe performance.
