How Does Electric Fence Shock Through the Plastic Conduit?

Electric fences are a common and effective method for containing livestock and deterring unwanted animals from entering a property. These fences are typically made up of multiple components, including a power source, conducting wires or tapes, insulators, and occasionally, plastic conduits. However, one may wonder how the electric shock can pass through the plastic conduit, which is designed to insulate and protect the wires from physical damage. The answer lies in the exceptional properties of the materials used in the construction of the conduit, as well as the nature of electric currents and their ability to exploit vulnerabilities within insulating materials.

Will an Electric Fence Shock a Human?

It’s important to understand how an electric fence works in order to debunk this misconception. Electric fences operate on the principle of delivering a high voltage, low amperage shock. When a person or animal comes into contact with the fence, the high voltage charge passes through their body and back into the ground, completing the circuit. This results in a temporary shock or jolt, but it doesn’t cause any significant harm.

The plastic conduit that encases the electric wire in an electric fence serves as an insulator, preventing the charge from escaping and reducing the risk of electric shock to humans or animals. It also provides an added layer of protection for individuals who may accidentally come into contact with the fence.

It’s worth noting that individuals with certain medical conditions, such as heart problems or implanted electronic devices, should exercise caution around electric fences. Consulting with a healthcare professional is advisable for those who may have concerns about the potential impact of an electric shock on their health.

Now let’s dive deeper into the various tactics employed by criminals to overcome the barrier of an electric fence.

How Do You Get Across an Electric Fence?

When it comes to understanding how electric fences can shock through plastic conduit, it’s important to consider the principles behind their functioning. Electric fences work by delivering an electric shock to any object or individual that comes into contact with the electrified wires. These wires are typically made of metal, such as steel or aluminum, and are connected to an energizer that generates the electrical pulse.

One reason for this is if the plastic conduit becomes damaged or degraded over time. Cracks, holes, or wear and tear in the conduit can expose the wires, allowing the electrical current to find a path of least resistance and shock through the conduit.

Furthermore, environmental factors can play a role in how well the plastic conduit maintains it’s insulation properties. Extreme temperatures, excessive moisture, or exposure to sunlight can degrade the plastic and compromise it’s ability to insulate the wires effectively.

Moving on to another aspect, it’s important to understand that electric fences operate on the principle of completing a circuit. When an animal or person touches both the charged wire of the fence and the ground, it closes the circuit and allows the electrical current to flow through them, resulting in a shock. However, without direct contact with the ground, the electricity has no path to complete the circuit, rendering the fence harmless. This characteristic also explains why birds can safely perch on electricity lines without experiencing shocks.

Will an Electric Fence Shock You if You Jump?

When it comes to the functioning of an electric fence, understanding how the shock is transmitted through the plastic conduit is crucial. In a typical electric fence setup, there are various components involved, including the energizer, wire conductors, insulators, and the plastic conduit. The plastic conduit acts as a protective covering for the wires, ensuring that they aren’t exposed to external elements that could potentially compromise the fences effectiveness.

So, how does the electric fence shock you if you jump? Well, the answer lies in grounding. When a person jumps or comes into contact with an electric fence while also touching the ground, they provide a path of least resistance for the electricity to flow through. The electricity will take advantage of this pathway and pass through the person, resulting in a shock.

Tips for Maintaining and Troubleshooting an Electric Fence System.

  • Regularly check the condition of the fence wires for any damage or breaks.
  • Inspect the insulators to ensure they’re intact and properly attached to the fence posts.
  • Clean the fence line from any vegetation or debris that may ground the system.
  • Test the voltage regularly using a fence tester to guarantee it’s effectiveness.
  • Inspect the grounding system to ensure it’s properly installed and functioning correctly.
  • Maintain a clear zone around the fence by trimming nearby trees or bushes.
  • Check the charger or energizer for any faults and ensure it’s providing adequate power.
  • Secure all connections and tighten loose wires to prevent power loss.
  • Regularly monitor and adjust the fence settings according to the specific needs of your animals.
  • Inspect the system after severe weather conditions to identify any damages or issues.


While it may initially appear counterintuitive for the electricity to pass through the plastic barrier, it’s crucial to consider the different factors involved. Although plastic is generally considered an effective insulator, it isn’t entirely impervious to electrical currents and can become conductive under certain conditions. These conditions may include the degradation of the plastic due to environmental factors or the presence of moisture or contaminants. By taking into account the various factors at play, practitioners and researchers in this field can strive to develop improved insulation materials and design techniques to minimize the risk of electric shock and enhance overall system performance.
