Definition of Fencing effectiveness

A fence with a minimum of 2 000 Volt at each point is deemed regulated safe in Germany. Every fencing system operator is obliged to monitor and regularly check his fencing system. A fencing system is deemed regulated safe if it is not dangerous to humans, animals or objects.

Commercial livestock owners must, in the event of claims for damages, prove (pursuant to § 833 BGB [Civil Code]) that the required due diligence with erection and operation of the electric fence was complied with.

Easily controlled animals

A fence output voltage of at least 2 000 Volt everywhere on the fence is adequate for easily controlled animals such as short haired cattle, horses, pigs and other domestic animals.

Hard to control animals

A fence output voltage of 4 000 Volt everywhere on the fence is recommended for animals that are hard to control, e.g. sheep or Highland cattle (animals with a dense coat) or to keep wild animals outside.

Correct earthing of the electric fencing energiser is an important factor to ensure proper functionality of the entire fence.

To allow the electric fencing energiser to produce full power, it is important to provide adequate earthing, i.e. to properly dimension the earthing (especially with sandy, rocky or dry soil).

230 Volt mains units and 12 Volt battery powered equipment

  • 1-3 earthing rods (depending on discharge / impulse energy)
  • length of the earthing rods: 1 – 2 m
  • distance between the individual earthing rods: 2 – 3 m

9 Volt battery powered equipment

  • 1 earthing rod
  • length of the earthing rod: 1 – 2 m

Additional earthing rods are recommended for sandy, rocky or dry soils and the earthing condition should be checked regularly. Galvanised or rust-resistant earthing rods should be used, since rust has insulating properties.
