⚫For any two separate electric fences, each supplied from a separate energiser which is independently
timed, the distance between the wires of the two electric animal fences must be at least 2.5m. If this
gap is to be closed, this must be using a non-conductive material or an isolated metal barrier.
⚫Barbed wire or razor wire must not be electrified by an energiser.
⚫A non-electrified fence incorporating barbed wire or razor wire may be used to support one or more
off-set electrified wires of an electric animal fence. The supporting devices for the electrified wires
must ensure that these wires are positioned at a minimum distance of 150mm from the vertical plane
of the non-electrified wires. The barbed wire and razor wire must be earthed at regular intervals.
⚫A distance of at least 10m must be maintained between the energiser earth electrode and any other
earthing system connected parts, such as a power supply system protective earth or a
telecommunication system earth.
⚫Connecting leads that are run inside buildings must be effectively insulated from the earthed
structural parts of the building. This may be achieved by using an insulated high voltage cable.
⚫Connecting leads that are run underground must be run in conduit of insulating material, or an
insulated high voltage cable must be used. Care must be taken to avoid damage to the connecting
leads by animal hooves or tractor wheels sinking into the ground.
⚫Connecting leads must not be installed in the same conduit as the mains supply wiring, communication
cables or data cables.
⚫Wherever possible, avoid crossing with overhead power lines. If such a crossing cannot be avoided, it
should be made underneath the power line and as near as possible to right angles.
⚫If connecting leads and electric fence wires are installed near an overhead power line, the clearances
should be not less than those shown below:
≤1000
＞1000 ≤33000
＞33000
⚫If connecting leads and electric fence wires are installed near an overhead power line, their height
above the ground should not exceed 3m.
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:
- 2m for power lines operating at a nominal voltage not exceeding 1000V;
- 15m for power lines operating at a nominal voltage exceeding 1000V.
⚫Electric animal fences intended for deterring birds, containing household pets or training animals
such as cows need to only be supplied from low output energisers to obtain a satisfactory and safe
performance.
⚫In electric animal fences intended for deterring birds from roosting on buildings, you must not
connect any electric fence wire to the energiser earth electrode. A warning sign must be fitted to
every point where persons may gain access to the conductors.
⚫Where an electric animal fence crosses a public pathway, a non-electrified gate must be incorporated
