An electric fence is an ideal and cost-effective solution for containing livestock long-term. For a safe and reliable fence, correct installation and maintenance is essential.
Safety and reliability are vital when dealing with electrical appliances so check your Energizer has IEC safety standard approval. Features such as lightning-protected circuitry and adaptive control will allow the output energy of the Energizer to adjust based on the amount of load resistance on your fence (e.g. long grass).
The size and type of Energizer you purchase needs to suit both your property size and the animals you wish to contain. This information is displayed on the front of all Gallagher Energizer packaging but discussing your requirements with someone in store or your local Gallagher Manager is always a good idea. For example, while the new Gallagher M10,000i Energizer indicates it can power up to 1,000 acres, factors such as fence condition can make this figure higher or lower.
When it comes to the proper installation of an Energizer, there are several things to consider. Effective transfer of power from the Energizer to the fence requires quality lead-out wire and cable with aluminium content such as Gallagher High Conductive Cable for long lead-out distances. If two Energizers are being installed, separate earths are needed and the fences should be at least 2.5m apart.
Eight out of ten power problems are due to improper earthing. Setting up a good earthing system is often overlooked but it’s a critical part of your electric fencing system, just as important as the wires and even the Energizer.
The general rule to follow with earthing is the 4-3-2-1 rule. That’s four metres between earth stakes, three earth stakes minimum, two metres minimum length of stakes in the ground and one wire connecting all earth stakes to the earth terminal on your Energizer. For Energizers with over 15 stored joules, add two earth stakes for every additional 10 stored joules of power.
Ground conditions also play a major part in earthing quality. In dry, low-mineral soil conditions a Super Earth Kit which is the equivalent of three earth stakes, is recommended. It includes absorbent bentonite clay to hold moisture and improve earthing. It is also important to install your earth away from your mains earth.
