REGULATIONS AND SAFETY POINTS
All mains operated energizers must comply with
various local standards. These standards vary but the following regulations
are common in most countries.
use insulated cable when connecting a ground system to the energizer
to ensure that no wires come into contact with sheds etc. This is
particularly important with milking sheds as cows are very sensitive
to even very low voltages in this environment.
An electric fence ground system should not be connected to any plumbing
system, including disused water pipes or old bore casings, nor should
it be connected to any other grounding device.
An electric fence earth system should be at least 133ft away from
any other electrical earth system or telephone earth system.
Each energizer should be connected to its own ground system and
this should not be connected to any other ground system.
Do not connect two or more energizers to the same electric fence.
Never connect any fence energizer to barbed wire of any description.
Do not attach an energizer or electrified wires to any post of any
overhead power line unless authorized to do so.
Try to avoid erecting a fence which runs parallel to or runs under
power lines. Where this is unavoidable the crossing should be underneath
the power lines and as near as possible at right angles to the lines.
Where a fence is in the vicinity of over head powerlines, no fence
wire should be higher than 6'6" above the ground.
Try to avoid running a fence line parallel
to telephone or telegraph lines or near any radio tower.
When an electric fence is installed where it might reasonably be
expected to be touched by the public, then warning signs must be
The warning sign must be at least 8" x 4" in size and
should be affixed to the fence at intervals not exceeding 295ft
The sign should also display the words ELECTRIC
FENCE or show the symbol depicted.
Any lettering should be indelible, at least
1" high and it is recommended that the color of the sign be
yellow with black inscription.
In areas prone to bushfires, power the fenceline
from the 1/2 voltage terminal or turn the energizer off on days
of extreme fire danger.
Where the energizer is used to supply a system of conductors used
for deterring birds from roosting on buildings, no conductor should
be connected to ground. A switch should be installed to provide
a means of isolating the energizer from all poles of the supply
and clear warning notices should be fitted at every point where
persons may have ready access to the conductors. The notice should
bear the words "LIVE WIRES" in block letters not less
than 1/2" high. The letters should be red on a white background
and the size of the notice should not be less than 2 1/2' x 2"
Do not connect on energizer simultaneously to a fence and to any
other device such as a Cattle Trainer or Poultry Trainer, otherwise,
lightning striking your fence will be conducted to all other devices.
If in doubt check the regulations with your local authority.
