Barbed or razor wire shall not be electrified by an energiser. Did you know you can get expert answers for this article? Winging it will ALWAYS result in a crooked fence. 
Avoid running the electric fence line parallel to power or telephone lines. Once you've done that, run a grounding wire from the charger to all of the grounding posts. For particularly poor earth conditions (sand, peat, gravel, very dry soil, snow or frozen ground) it is possible to increase the earth efficiency by: To test an Earth Spike installation, firstly short out the live fence line to ground, either with a metal stake or by laying the fence line on the ground for about 100 metres and at least 30 metres away from the energiser. The resulting high voltage pulse is applied to the pulse transformer and then to the fence line and when the animal touches the fence the animal completes the circuit via the ground and the animal receives a shock. Not only does the termination knot look and work great, but it also ensures that the wire is not grounding out on the end post. For an electric fence to be properly installed it should not be a closed loop. Watch the following video to see exactly how to complete the termination knot on your electric fence. When the battery requires recharging it will go RED as well. Connecting leads shall not be installed in the same conduit as the mains supply wiring, communication cables or data cables. Along the course of the average fence there are many conditions that will divert or impede the flow of electricity. Don't buy chargers with foot or mile power ratings, instead select a charger that's rated by joules. As long as the grounding wire doesn't touch the live wire, you should be fine. Gateways and major changes of fence direction are ideal places to put cut out switches for maintenance and fault finding.
So put on some work gloves and lets get started! Connect the fence sections under gateways rather than over, using double insulated HTG cable run in a protective plastic pipe at least 25cm deep. If in doubt, it is always better to add an extra line. If connecting leads and electric fence wires are installed near an overhead power line, their height above ground shall not exceed 2 m. 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 - 2 m for power lines not exceeding 1000 V - 15 m for power lines exceeding 1000 V. A distance of 10 m shall be maintained between the energiser Earth Spike and any other earthing system such as the power supply system protective earth or the telecommunication system earth. An electric fence system consists of an electric fence energiser , a fence wire or combination of wires supported on insulators , fixed on posts. If your fence doesnt carry a strong enough shock, your soil may be a poor conductor.
As mentioned above, the termination knot is the most effective way to end an electric fence.
This article was co-authored by Anthony "TC" Williams. My house is completely surrounded by woods. He is a Idaho Registered Contractor and a previously Licensed Irrigator in the State of Texas. the solar fencing in a proper way. Sagging or broken wires can contact un-insulated wires or the ground. There are specific clips made for both the front and top of the fence, allowing you to choose the precise height for your electric fence.
These together with the EARTH system, form a pulsed high voltage OPEN LOOP with the animal being the completing link. The electric wire is the first thing most people think of when they hear the words electric fence and although wire is a common material used in constructing electric fences, other more visible options. The Energiser Earth System must be 10 m away from the mains supply, safety Earth and buried water pipes. Connecting leads that are run inside buildings shall be effectively insulated from the earth structural parts of the building. It may also make your system more reliable and less likely to get shorted. Run the energiser with both the fence and earth leads disconnected. How do I connect the wire to complete the circle/corral?
Most common are are insulators that allow braided or rope style fencing enough space to slide through, helping to avoid rubbing. Thank you. Unfortunately we are currently unable to ship to Jersey and Guernsey. Fence Frenzy is compensated for referring traffic and business to these companies.
Cut 3 feet of wire for every line of hot wire. Additionally, electric fencing can be purchased in a variety of forms. You are going to need a power source designed for the size of your pasture as well as the type of electric fencing used. All Gallagher energisers are built to the highest safety standards. (Not the sword kind). Although some choose to just cut the wire and tie it off to an insulator, a termination knot looks more professional and will be more durable in the long run.
The 6-volt and 9 volt energiser, the light (if fitted) will flash bright RED indicating that the energiser is working correctly. After all these years, the fence has held up well, and we've helped some of our friends and family put up fences too. % of people told us that this article helped them. We at Fence Frenzy absolutely love taking on the challenge of building, or even restoring, a fence. The wire should be tight for large animals. The best part about using t-posts for electric fencing is the clip-on insulators.
After you install the fence posts, brace the corners and gates to reinforce them. This may be achieved by using double insulated high voltage cable HT or HTG Cable. For maximum efficiency use a multi-wire system consisting of at least 3 wires connected in parallel. If you get a shock from the Earth Spike before you short the fence line, then there is a poor Earth AND possibly a fault on the fence line as well. If connecting leads and electric fences are installed near an overhead power line the clearances shall be:1. The Gallagher mains energiser works on the same principle except the mains voltage is doubled, dispensing with need for an oscillator circuit, using a voltage doubler network which in turn charges up the reservoir capacitor to the required voltage (approximately 700volts). Push the Earth Spike or Stand into moist ground. Make sure the ends of the pipe are turned down to prevent water entering. The choke can be made quite simply and causes a blocking effect for the extremely high voltage of the lightning so that it jumps the silicon carbide discs in the arrestor and is diverted to ground. To install an electric fence, start by setting up an electric charger near an AC outlet or a solar charger in a sunny spot. Disclosure. Both humane and effective, electric fence lines can be used to enclose a pasture or garden, and are simple to install and maintain. This hoop is then placed on the post at the end of the fence and locked in place with a fence staple at the proper height. Cracked or broken insulators, or insulators of a poor design will allow electricity to leak to the fence post and down to earth. The posts are pounded and the hot wire is strung, but what do you do now? If you are experiencing interference please follow the checklist below: To locate sparking caused by leakage, faulty joins, broken wires or faulty insulators, walk the fence line with a transistor radio tuned off station on the AM band on high volume. The ground is only important where your earth stakes go. To keep the charger protected, hang the charger on a post or wall of an outbuilding. Does the grounding wire need to be insulated? An effective EARTH system is three 1 metre steel spikes (Part No ES2) driven fully into the soil approximately 3 metres apart and joined together and if possible buried in the ground with 2.5mm galvanised steel cable. You should ensure that grass, weeds, branches (even dead ones) do not touch the fence and provide a route to ground for the electricity.
The inscription shall be black and shall be the substance of TAKE CARE - ELECTRIC FENCE. With over 21 years of landscaping experience, TC has worked on projects such as the Idaho Botanical Garden in Boise, Idaho. The average pulse duration is one hundred millionths of a second with at least 1 second between pulses. For the best experience on our site, be sure to turn on Javascript in your browser. (A car battery is not recommended as they are not designed to be deeply discharged). The barbed / razor wire shall be earthed at regular intervals.
Energisers with an Earth leakage-monitor will indicate the condition of the Fence Line. In areas of very poor earth conditions it may be necessary to run an earth returns system.
Deer cannot judge three dimensionally and must 'measure' first. It can be of benefit to have a selection of electrified fencing in a field along with normal stock fencing in order to train naturally curious young animals for later when moving the animals to a fully electrified enclosure. For an electric fence to be properly installed it should not be a closed loop. To learn how to design the layout for an electric fence, keep reading! See our earthing advice section. Coated wire is likewise easy to see and to install. Position the energiser near to the fence Line. When enough conditions exist to draw all of the electricity produced by the energiser from the fence, the fence is said to be `shorted out '. These problems do not draw voltage and amperage to earth, but they do impede the flow of electricity along the fence, contributing to the fence load. Part number ES2).
Although typically used for more temporary fences, poly fencing has become more common in use with livestock. Please note that the fence line does not need to form a complete loop. Can the ground wire be welded (soldered) to the ground rod?
A temporary Tape Gate can be installed at the end or beginning of a temporary fence system.
Good effective grounding of the fence energiser. This method is best used with hot wires on a wooden post although it could be used with poly rope fencing as well.
P35). This is normally caused by bad joints, leaking insulation or vegetation touching the fence line. Connecting leads and electric fence wires shall not cross above overhead power or communication lines.
However, you can use any type of electric fencing or posts with a gate. Decide on the length of each run, as well as the height and the number of wires necessary to complete the job. If all of the above have been implemented and there is still a problem, then carry out the following test to locate the fault. The end of runs will simply be made into a loop and wound over on itself. We do not recommend Electro Plastic wire/tape for fences over 800 metres of single strand. For greater distances we recommend galvanised or high tensile steel wire. Connecting leads that are run underground shall be run in a conduit of insulating material. The Fence (Red) output terminal is connected to the fence line, The Earth (Black) output terminal is connected to the Earth Spike. To find out if the fault is in the energiser or the mains power supply, carry out the following tests: Disconnect the earth and fence leads from the energiser terminals and have someone at the offending radio to count the clicks. Always try to install the earth system in a permanently damp area. After you have strung the entirety of your fence, wrap the electric fencing tightly around the insulator just before the gate opening (this is to prevent the whole fence from slacking when the gate is opened). This is rectified and this DC voltage is used to charge up the reservoir capacitor. Rusty wire, poor splices, or wire of insufficient diameter to carry the flow of voltage and amperage also contribute to fence load. The energiser earth cable must not touch buildings, which can act as a broadcast aerial. The short answer is: no. Do not turn the charger on until you've installed the fence. Where an electric animal fence crosses a public pathway, a non-electrified gate shall be incorporated in the electric fence at that point or a crossing by means of stiles shall be provided. Can weeds touching the lower wire of an electric fence cause a short in the fence's electrical system?
Now, we've decided to put all of our knowledge on this website to help anyone who needs it.
Electric fences shall be installed and operated so that they cause no electrical hazard to persons, animals or their surroundings. If the fencing is going to span the entire perimeter of the pasture, the fence will begin and end on the same fence post. Weeds or vegetation growing on the fence line is the most common culprit contributing to a heavy fence load.
The inscription shall be indelible, inscribed on both sides and have a height of at least 25 mm. No Loose Connections. This energy is then discharged through the Pulse Transformer primary via the thyristor switch at a rate of not more than once per second. If the RED light stays ON, check the battery. Each of these poly fencing types is essentially plastic stings woven around or with small, conductive wires.
In this chapter, we will discuss the basic steps you need to take to successfully construct your fence, including: The steps you will need to take to build your fence will vary with the type of fencing you have chosen to suit your needs.
However, using an insulated wire for the grounding wire may extend its life. Measure the voltage between the GROUND and the Earth Spike with a meter (Part No. In dry and poor EARTH conditions it may be necessary to add additional Earth Spikes at approximately 3m intervals.
Try another power socket, check the radio plug wiring and if still not corrected, install a simple earth and aerial for the radio. The first thing you are going to need is a set of corner post insulators (often referred to as donut insulators) and crimp sleeves.
When animals are to be left out in electric fenced areas in frozen snowy conditions you can improve the electric fence function by running a live/earth return system.
Once your fence is complete, the final step is to electrify it!
An electric fence shall not be supplied from more than one energiser or from independent fence circuits of the same energiser. Pro Tip: Be sure to string a guide wire so that your t-posts are installed in a straight line. ", "This article helped me with specific steps on how to install an electric fence.
Electric fences intended for deterring birds, household pet containment or training animals such as cows need only be supplied from low output energisers to obtain satisfactory and safe performance. Rather, each insulator clip must be tightly screwed into at least every other fence post (this may depend on the spacing of your posts). Power Line Voltage: Under 1000 volts - Clearance: 3 Metres2. For now, feel free to continue reading. This spring helps keep tension on the fence while also giving it enough slack to open and close.
The effectiveness of the fence is the shock, in both the meanings of the word.
When an animal touches the electric fence, this should be the missing link in the loop for the animal to get the shock. String another wire of the fence and attach the ground wire to that instead of the ground post. The only thing left to do now is to turn the power to your fence on.
Electric fence constructions, which are likely to lead to entanglement of animals or persons, shall be avoided.
Making sure that the fencing is easy to see is one of the most important considerations. Most of these are plastic with metal on each end and a loaded spring inside. link to Can a Fence Post Support a Hammock. Collectively, these conditions are known as the `fence load '. For short distances the earth lead may be connected to the stand. Don't use too many posts.
An electric fence is a less-than-ideal environment on which to conduct electricity. This is also the reason why a stronger energiser is recommended when the fence is placed in high vegetation. Connect all live wires together at the beginning and end of each fence section. Rather than taking the time to drill a hole for an insulator to fit in and then painstakingly twisting the insulator into place, plastic insulators can be clipped directly onto the fence in a matter of seconds. Consult with your (Zareba / Fi-Shock) fencing expert for more detailed steps on building specific fencing types. A non-electrified fence incorporating barbed wire or razor wire may be used to offset electrified wires of an electric animal fence. Particularly useful in areas of high vegetation. At this point, you either have your main fence built or at least a plan for how you want it constructed. As with all energisers there must be a return path through the ground and Earth Spike back to the energiser in order to complete the loop. See the Earth Return System section. Make sure you plan your fence layout well.
Frozen ground also reduces the flow of current. If this click is not heard, then the interference is being transmitted by the mains power supply. Green plants draw voltage and amperage from the fence to earth. Run out the wires between the end posts using suitable insulators and tension the wires until there is only slight sag. If this is above 200 volts the earth installation is inefficient. Building a fence requires a combination of quality materials, use of proper construction techniques, and some elbow grease. The clicking will get louder as the fault is approached. Always bear in mind that all electrical circuits must form a complete loop from the positive (live) to the negative (earth) is just as much part of the circuit as the fence line and the animal is the missing link that completes the loop. 5 Great Alternatives to Barbed Wire Fencing. link to 5 Great Alternatives to Barbed Wire Fencing.
If the battery is connected the wrong way round a buzzer will sound. Although wooden posts tend to look and work better for keeping animals in a specific area, installing them is also time-consuming. Stay tuned for the first newsletter in the morning, straight to your inbox. We use cookies to make wikiHow great. A P74 Lightning arrestor kit is recommended to minimise damage to your energiser.
When the gate is opened the gate is disconnected from the power and the gate becomes dead and will not affect the live fence if dropped to the ground. The timing circuits and triggering principles remain the same as the battery units. Approved. Learn how to install a gate in your electric fence in the video below.
The only other piece you will need is an electric fence handle. Learn more about choosing the proper power bank for your fence from Gallagher, a popular electric fencing company. Pro Tip: I suggest doing the termination knot before stringing the fence wire in order to keep the line taught all the way around the perimeter. Regularly check the fence line for vegetation growing over the fence line of fallen branches, as this will reduce the voltage on the line. If the last click was still heard on the radio, the problem is with the energiser itself and it should be returned to Gallagher with a note explaining the problem. ", Unlock expert answers by supporting wikiHow, http://theurbanrancher.tamu.edu/construction/fencesforthefarm.pdf, http://beefmagazine.com/pasture-range/grazing-programs/0301-common-fencing-mistakes?page=1. A guide from Electric Fence Online, Receive 90 grant on your next Solar Energiser, Keep your garden contained How to keep cats out of your garden. Using Double Insulated HT cable connect the Live, normally Red, (Units with a Blue terminal: this is a half power terminal) Fence line output terminal to the fence line. When we moved into our first house, we were so excited, but the back yard didn't have a fence.
When an animal touches the electric fence, this should be the missing link in the loop for the animal to get the shock. Proper construction with quality components, installing an adequately powered energiser, a proper earth installation and good management practices are the key to keeping fence load under control. Some flash red to show operating normally, some flash green when OK, then turn red when the battery charge is low or failing.
Wet weather will magnify all of these problems. The 12-volt energisers will flash GREEN, at about one pulse per second. Depending on the size of the capacitor and the DC voltage determines the stored energy (volts' x capacitance 12 = Stored Joules).
Although ending an electric fence seems complicated, there are several methods that make completing the task quite simple. The wires will need to be pulled taut at the anchor end. 1.5- or 2-inch poly tape, braid, rope are perfectly effective for most purposes.
Protect all your hard work by typing bright ribbons or pieces of fabric onto your electric fence. Support wikiHow by Consequently the ground is just an important part of the fence as the fence line itself. Check the connections or increase the number of Earth Spikes.
Lightning always finds the easiest path to ground. This type of electric fencing can carry a stronger charge over a much further distance than other types of electric fences. Do not use spring type electric gates to get power across to the other section as this may cause arcing and burn out the connectors of the gate handles. The energiser's ground system should be at least 10 m away from radios and buried telephone wires. The earthing system is an integral part of your energiser's performance.
The Energiser Earth system must be sufficient. Do not handle PVC cords when the temperature is below +5 degrees centigrade.
Depending on the type of post as well as the style of electric fencing selected, certain methods of ending the fence will work better than others.
