Minimum clearances from power lines for electric animal fences
Power line voltage (V)
≤ 1 000
> 1 000 ≥ 33 000
> 33 000
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.
This height applies either side of the orthogonal projection of the outermost conductors of the power
line on the ground surface, for a distance of
2 m for power lines operating at a nominal voltage not exceeding 1 000 V;
15 m for power lines operating at a nominal voltage exceeding 1 000 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 per-
formance.
In electric animal fences intended for deterring birds from roosting on buildings, no electric fence
wire shall be connected to the energizer earth electrode. A warning sign shall be fitted to every point
where persons may gain ready access to the conductors.
Fence wiring should be installed well away from any telephone or telegraph line or radio aerial.
Ensure that all mains operated, ancillary equipment connected to the electric animal fence circuit
provides a degree of isolation between the fence circuit and the supply mains equivalent to that pro-
vided by the energizer.
WARNING: Risk of Electric Shock. Do not connect the Energizer simultaneously to a fence
and to any other device such as a cattle trainer or a poultry trainer. Otherwise, lightning
striking your fence will be conducted to all other devices. This Energizer complies with
international safety regulations and is manufactured to international standards. Manufac-
turer reserves the right to make changes without notice to any product specification to
improve reliability, function or design.
