the ver cal plane of the non-electrifi ed wires. The barbed wire and razor wire
shall be earthed at regular intervals.
•
Follow the energizer manufacturer's recommenda ons regarding earthing.
•
Do not install an earth (ground) system for your electric fence within 10 m (33
) of any power, telecommunica ons or other system.
•
Except for low output ba ery operated energizers, the energizer earth
electrode should penetrate the ground to a depth of at least 1 m (3 ).
•
Use high voltage lead-out cable in buildings to eff ec vely insulate from the
earthed structural parts of the building and where soil could corrode exposed
galvanised wire. Do not use household electrical cable.
•
Connec ng leads that are run underground shall be run in conduit of insula ng
material or else insulated high voltage lead-out cable shall be used. Care must
be taken to avoid damage to the connec ng leads due to the eff ects of animal
hooves or tractor wheels sinking into the ground.
•
Connec ng leads shall not be installed in the same conduit as the mains supply
wiring, communica on cables or data cables.
•
Connec ng leads and electric animal fence wires shall not cross above
overhead power or communica on 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 connec ng 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
Less than or equal to 1 000
Greater than 1 000 and less than or equal to 33 000
Greater than 33 000
•
If connec ng 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 projec on of the outermost
conductors of the power line on the ground surface, for a distance of:-
- 2 m for power lines opera ng at a nominal voltage not exceeding 1 000 V;
- 15 m for power lines opera ng 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 sa sfactory and safe performance.
•
In electric animal fences intended for deterring birds from roos ng on
buildings, no electric fence wire shall be connected to the energizer earth
