Connecting leads that are run underground shall be run in
conduit of insulating material or else insulated high voltage
cable shall be used. Care must be taken to avoid damage to
the connecting leads due to the effects of animal hooves or
vehicle wheels sinking into the ground.
Connecting leads shall not be installed in the same conduit as
the mains supply wiring, communication cables or data
cables.
Connecting leads and electric animal fence wires shall not
cross above overhead power or communication lines.
Crossings with overhead power lines shall be avoided
wherever possible. If such a crossing cannot be avoided it
shall be made underneath the power line and as nearly as
possible at right angles to it.
If connecting leads and electric animal fence wires are
installed near an overhead power line, the clearances shall
not be less than those shown in the table below.
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.
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.
Where an electric animal fence crosses a public pathway, a
non-electrified gate shall be incorporated in the electric
animal fence at that point or a crossing by means of stiles
shall be provided. At any such crossing, the adjacent
electrified wires shall carry warning signs.
Any part of an electric animal fence that is installed along a
public road or pathway shall be identified at frequent
intervals by warning signs securely fastened to the fence
posts or firmly clamped to the fence wires.
The size of the warning sign shall be at least
100x200 mm (4x8").
Clearance
3 m (10')
4 m (13')
8 m (27')
The background colour of both sides of the warning
sign shall be yellow. The inscription on the sign shall
be black and shall be either:
or the substance of "CAUTION: Electric fence".
The inscription shall be indelible, inscribed on both
sides of the warning sign and have a height of at least
25 mm (1").
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 provided by the energizer.
Protection from the weather shall be provided for the ancillary
equipment unless this equipment is certified by the
manufacturer as being suitable for use outdoors, and is of a
type with a minimum degree of protection IPX4.

necessary, remove obstructions

Check that the energizer rating
is adequate for the length of the
fence. If necessary, reduce the
length of the fence or reduce the
number of fence wires.
Alternatively, divide the
fence-line into smaller zones,
with each zone powered by a
separate energizer.
