how to connect polywire to charger

Polywire is commonly used in electric fencing systems for livestock and other purposes. To connect polywire to an electric fence charger (also known as an energizer or controller), you’ll need to ensure a proper electrical connection to ensure the fence functions effectively and safely. Here’s a step-by-step guide:

Materials You’ll Need:

  • Polywire
  • Electric fence charger
  • Insulated wire or lead-out wire
  • Wire connectors or crimp sleeves
  • Grounding rod and grounding system (if not already in place)
  • Electric fence tester (optional, but recommended for safety)


  1. Safety First:
    • Before working with electric fencing, ensure that the fence charger is turned off or unplugged to avoid accidental shocks.
  2. Select a Suitable Location:
    • Choose a location for the fence charger that is near a power source and protected from the elements (if it’s not already installed). Install the charger according to the manufacturer’s instructions.
  3. Install Grounding (if necessary):
    • If your electric fence charger requires grounding (most do), install a grounding rod and grounding system according to the manufacturer’s guidelines. Proper grounding is essential for the effective operation of the electric fence.
  4. Prepare the Polywire:
    • Cut the polywire to the desired length for your fence run. Make sure you have enough to reach from the charger to the fence perimeter.
  5. Connect Polywire to the Charger:
    • Locate the terminal or connection point on the electric fence charger where the fence wire is connected. This is typically labeled as the “fence” or “hot” terminal.
    • Strip a small section of the polywire’s insulation (usually about an inch or so) to expose the inner conductor.
    • Twist the exposed conductor of the polywire together to ensure it’s tightly wound.
  6. Attach the Polywire to the Charger:
    • Use a wire connector or crimp sleeve to attach the twisted end of the polywire to the “fence” or “hot” terminal on the charger. Follow the manufacturer’s recommendations for the type of connector to use.
  7. Test the Connection (Optional):
    • Before fully securing the polywire to the fence posts, it’s a good idea to test the connection. Turn on the fence charger and use an electric fence tester to ensure that electricity is flowing through the polywire. Be cautious and avoid touching the wire during the test.
  8. Secure the Polywire to Fence Posts:
    • Attach the polywire to your fence posts or insulators using suitable fasteners or clips designed for electric fencing. Ensure that the polywire is taut and properly spaced to create an effective fence.
  9. Turn On the Charger:
    • Once the polywire is securely attached to the fence posts, turn on the electric fence charger to begin energizing the polywire.
  10. Regular Maintenance:
    • Periodically check the fence for any damage or issues, and ensure that the charger is functioning correctly. Maintain the grounding system as needed.

Remember that working with electric fences can be hazardous, and it’s important to follow safety precautions and guidelines provided by the manufacturer of your electric fence charger. Additionally, consult local regulations and guidelines regarding the use of electric fencing for livestock or other purposes in your area.
