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 |
| Clearance | |
≤1000 | V |
| 3 m (10') |
>1000 | V to ≤33,000 V |
| 4 m (13') |
>33,000 V |
| 8 m (27') | |
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
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").
•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 animal fence".
•The inscription shall be indelible, inscribed on both sides of the warning sign and have a height of at least 25 mm (1").

Frequently asked questions/Troubleshooting
What voltage is required to control animals?
4 kV is widely accepted as the recommended minimum voltage to control animals. However, you also require a well constructed fence system to ensure that animals cannot push through electrified wires.
The fence voltage is below 4 kV. How do I increase the voltage?
Check the energizer. Disconnect the fence wire from the energizer's fence output terminal. Measure the voltage across the energizer terminals with a Fault Finder or Digital Voltmeter. If the voltage is less than 6 kV, the energizer may require servicing.
Check the energizer earthing. Use the procedure described in Installing and testing an earth system on page 8.
Check the fence system for faults. The most common source of low voltage is faults on the fence line.
If the fence, earth and energizer are in good condition and the voltage is still below 4 kV, talk to your nearest reseller. Recent extensions to your fence, a poor fence layout, or soil conditions may be causing inadequate voltage.
How do I locate faults?
The recommended tool for locating faults is a Fault Finder. This combined voltage and current meter allows you to rapidly locate sources of current leakage. Alternatively, use a Digital Voltmeter. Use
There are no lights flashing on the energizer.
Check the power supply to ensure that the power is switched on. Check the fence system for faults (see above). Check the energizer (see above). If the energizer still does not operate, it may require servicing.
