Minimum clearances from power lines for electric animal fences
Less than or equal to 1 000
Greater than 1 000 and less than or equal to 33 000
Greater than 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 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.
•
Fence wiring should be installed well away from any telephone or telegraph line or radio aerial.
•
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 by
electric fence warning signs (G6020) at regular intervals that are securely fastened to the fence posts or
firmly clamped to the fence wires.
•
The size of the warning sign shall be at least 100mm x 200mm.
•
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:
the substance of "CAUTION: Electric Fence" or,
-
the symbol shown:
-
•
The inscription shall be indelible, inscribed on both sides of the
warning sign and have a height of at least 25mm.
•
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.
This energizer complies with international safety regulations and is manufactured to international standards.

SERVICE OF DOUBLE-INSULATED APPLIANCES
In a double-insulated controller, two systems of insulation are provided instead of grounding. No equipment
grounding means is provided in the supply cord of a double-insulated controller, nor should a means for
equipment grounding be added to the controller. Servicing a double-insulated controller requires extreme care
and knowledge of the system, and should be done only by qualified service personnel. Replacement parts of a
double insulated controller must be identical to the parts they replace. A double insulated controller is marked
with the words "DOUBLE INSULATION" or "DOUBLE INSULATED". The symbol for double insulation
be marked on the appliance.
