Choosing the Right Materials
When selecting materials for an electric fence, it’s crucial to consider several factors to ensure effectiveness, durability, and safety.
Conductors
Conductors carry the electrical current through the fence. The most common options include:
Polywire
Polywire is a lightweight, flexible conductor made of multiple strands of stainless steel wire encased in a tough polymer coating. It is inexpensive, easy to install, and suitable for temporary or movable fences.
Polytape
Polytape is wider than polywire and consists of flat strands of stainless steel or aluminum sandwiched between layers of polyethylene plastic. It is more visible, provides better insulation, and withstands higher voltages than polywire.
Braided Wire
Braided wire comprises multiple strands of steel or aluminum wire twisted together to create a high-strength conductor. It is the most expensive option but offers excellent conductivity, durability, and longevity.
Other considerations include wire gauge (thickness), tensile strength, and conductivity. It’s essential to select conductors with the appropriate specifications for the intended purpose and environmental conditions.
| Conductor Type | Gauge | Tensile Strength | Conductivity |
|---|---|---|---|
| Polywire | 16-12 AWG | 250-400 lbs | 0.1-0.2 mS/m |
| Polytape | 1/2-1″ | 300-600 lbs | 0.2-0.4 mS/m |
| Braided Wire | 12-8 AWG | 600-1200 lbs | 0.4-0.8 mS/m |
Planning the Fence Layout
2. Determine the Fence Line
Thoroughly survey the perimeter you intend to fence, paying close attention to any existing obstacles such as trees, structures, or changes in terrain. These factors will influence the fence line’s path and the type of fence system required.
Assessing Obstacles:
| Obstacle | Consideration | Possible Solution |
|---|---|---|
| Trees | Roots can interfere with underground wiring or posts. | Avoid placing posts near tree trunks or consider above-ground wiring. |
| Structures | Buildings or walls may require special mounting configurations. | Use standoff insulators or mount posts on the structure’s exterior. |
| Slopes | Uneven terrain can create challenges for post placement and wiring. | Consider using stepped posts or terraces to level the ground. |
Other Considerations:
- Property Lines: Ensure the fence line does not encroach on neighboring properties.
- Gates: Plan access points by installing gates at appropriate locations.
- Visibility: Make the fence visible by trimming vegetation or using reflective fencing materials.
- Safety: Place warning signs along the fence line to alert people of the electrical hazard.
Attaching the Wire
Once the posts are in place, it’s time to attach the wire. There are several different ways to do this, but the most common method is to use insulators.
Insulators are small plastic or ceramic pieces that keep the wire from touching the ground or other objects. They come in various shapes and sizes, so choose the ones that work best for your fence and the type of wire you’re using.
To attach the wire to the insulators, simply slip the wire through the hole in the insulator and tighten it down with a pair of pliers. Make sure the wire is pulled tight, but not so tight that it will snap.
If you’re using more than one strand of wire, you’ll need to space the insulators evenly apart so that the wires are parallel to each other. You can use a measuring tape to ensure that the wires are spaced correctly.
Once the wire is attached to the insulators, you can connect it to the energizer. The energizer will provide the electric current that will flow through the wire and deter animals from touching it.
Types of Insulators
There are many different types of insulators available, each with its own advantages and disadvantages. Here is a table summarizing the most common types:
| Type | Advantages | Disadvantages |
| Screw-in insulators | Easy to install, inexpensive | Not as strong as other types, can be damaged by animals |
| T-post insulators | Strong, durable | More difficult to install, more expensive than screw-in insulators |
| Ceramic insulators | Very strong, durable | Expensive, can be difficult to find |
Connecting the Energizer
5. Connecting the Fence to the Energizer
This is the final step in completing your electric fence. You will need to attach the fence wire to the energizer using either a direct connection or a fence post insulator.
Direct Connection
- Strip the insulation off the end of the fence wire about 2 inches.
- Wrap the bare wire around the terminal on the energizer and tighten it with a screwdriver.
- Repeat this process for the ground wire.
Fence Post Insulator
- Insert the fence wire into the hole in the fence post insulator.
- Wrap the wire around the insulator and tighten it with a screwdriver.
- Attach the ground wire to the ground rod using a ground clamp.
| Type of Connection | Pros | Cons |
|---|---|---|
| Direct Connection | – Simpler to install | – Less secure than fence post insulators |
| Fence Post Insulator | – More secure than direct connection | – More difficult to install |
Once the fence is connected to the energizer, you can turn on the energizer and test the fence with a voltmeter. The voltmeter should read between 5,000 and 10,000 volts.
Grounding the Fence
Proper grounding is essential for the effective functioning of an electric fence. It provides a path for the electrical current to return to the ground, completing the circuit and delivering a shock to any animal that touches the fence.
Ground Rods
Ground rods are metal rods driven into the ground to establish a low-resistance path to the earth. The length, diameter, and material of the ground rods will depend on the soil conditions and the size of the fence.
For most home applications, 8-foot-long, 1/2-inch-diameter copper-plated steel ground rods are sufficient. Insert the ground rods at least 6 feet deep into the soil, spaced approximately 25 feet apart along the fence line.
Ground Wire
Ground wire is used to connect the fence wire to the ground rods. Use a minimum of 14-gauge bare copper wire or a dedicated ground wire designed for electric fences. Connect the ground wire to the fence wire using a fence clamp or wire nuts, and then run the wire to the ground rods.
Grounding System
The grounding system should form a closed loop, ensuring that the current flows in a continuous path. Connect the ground wire to the ground rod at one end of the fence line, and then extend the wire along the other side of the fence line, connecting it to the remaining ground rods. Ensure that the wire forms a complete loop, returning to the first ground rod.
| Soil Condition | Ground Rod Length |
|---|---|
| Dry, Sandy Soil | 10 feet |
| Moist, Clay Soil | 6 feet |
Testing the Fence
Once the fence is installed, it’s important to test it to ensure it’s working properly and is delivering an effective shock. Here are detailed steps to guide you through the testing process:
1. Gather the Necessary Equipment
* Voltage tester
* Ground rod tester
* Multimeter (optional)
2. Establish a Ground Reference
* Drive a ground rod into the ground near the fence line.
* Connect the ground rod tester to the ground rod and set the dial to “ohms.”
* Touch the other probe to the bare ground.
* The tester should read “0” or “near 0” ohms. This establishes a good ground reference.
3. Check Fence Voltage
* Set the voltage tester to the appropriate voltage range (typically 6,000-10,000 volts).
* Connect one probe to the fence wire and the other probe to the ground rod.
* The tester should read the voltage output of the fence. Ensure it meets the recommended voltage range for your application.
4. Check Fence Continuity
* Connect the multimeter to the fence wire and the ground rod.
* Set the multimeter to the “continuity” setting.
* There should be continuity, indicating that the fence has a complete circuit.
5. Test for Leaks
* Use a voltage tester or a piece of insulated wire to check for any leaks along the fence line.
* Touch the probe or wire to the fence wire and then to the ground.
* If the tester detects voltage, there is a leak that needs to be repaired.
6. Test Arc Distance
* Hold a piece of insulated wire about 6 inches away from the fence.
* Slowly move the wire towards the fence until an arc forms.
* The arc distance should be at least 6 inches.
7. Monitor Over Time
* Periodically check the fence voltage and continuity using a multimeter.
* Replace batteries in the fence charger as needed.
* Inspect the fence line for any damage or vegetation growth that could compromise its effectiveness.
Troubleshooting Common Issues
Voltage Drop
Voltage drop occurs when the electrical resistance of the fence line is too high, causing a decrease in voltage along the fence. This can be caused by overgrown vegetation, loose connections, or a thin or corroded wire. To resolve, trim vegetation, tighten connections, and replace damaged wire.
Ground Fault
A ground fault occurs when the electrical current finds a path to the ground through unintended means, such as a tree limb touching the fence or a broken insulator. This can cause the fence to become ineffective. To fix, identify and remove the source of the fault.
Electric Leakage
Electric leakage can occur through damaged insulators, especially during wet weather. This can reduce the effectiveness of the fence. To resolve, replace damaged insulators and ensure that vegetation is not touching the fence.
Fence Charger Malfunction
A malfunctioning fence charger can render the fence ineffective. If the charger is not producing a sufficient voltage, it may not be able to deter animals. Check the charger for power and ensure that it is properly grounded.
Animals Adapting to Electric Fences
In rare cases, animals may adapt to electric fences. This can occur if the fence is not delivering a consistent shock or if the animals are repeatedly exposed to it. To prevent this, ensure a strong electrical pulse and rotate the location of the fence periodically.
Natural Lightning Strikes
Lightning strikes can damage electric fences, especially if they are not properly grounded. To minimize damage, install lightning arrestors at strategic points along the fence line.
Wire Breakage
Wire breakage can occur due to animal impact, fallen branches, or corrosion. A broken wire will prevent the fence from delivering a shock. To fix, locate the break and repair or replace the wire.
Vegetation Overgrowth
Overgrown vegetation can touch and short out the fence, reducing its effectiveness. Regularly trim vegetation around the fence to prevent this issue. Additionally, consider using heavy-duty wire or polywire that is less susceptible to damage from vegetation.
Maintaining the Fence
An electric fence is quite reliable, but periodic maintenance is required to ensure it operates optimally. Here are some key maintenance tips:
1. Monitor Wire Tension
Loose wires can reduce fence effectiveness. Regularly check the tension and adjust the wire supports as needed.
