Electrical Terms

  • Joules (Joules = Amps x Volts x On Time): This is a measurement used to define the amount of electrical work being done or the electrical energy required to exert a certain force. In Layman's terms, it's the distance in which a fence charger will send the electrical energy. 1 joule is equal to 1 watt for 1 second. 
  • Watts (Watts = Volts x Amps): A measurement used to define the available power in a circuit and the consumption of the devices operating on that circuit. Watts are seldom used to define the power consumption of a fence charger and are more used to determine how much of a load is on a circuit for your home. 
  • Voltage (Volts = Amps / Resistance): Volts are a unit of electrical pressure, causing the electrical current to flow. It's the force that pushes the energy.  
  • Amperage (Amps = Volts / Resistance): An amp is the measurement of the flow of the electrical current and is what you feel when you experience a shock.  
  • Resistance: Resistance is any obstacle (low magnetic values in the fence wire, poor connections, lack of conductivity in the earth, etc.) that restrict the flow of electricity, thus causing a decline in voltage. Resistance is measured in Ohms and is what causes a decline in voltage; it's very important to know the voltage your fence charger generates at a given Ohm load. 
  • Ohms: The measure of resistance. Zero Ohms equals total resistance/no power flow. The term "Ohm Load" is used to determine the available power of a fence charger at a specific level of resistance (example: 4,000V @ a 500 Ohm Load).


Electrical Invariables

  • Electricity must flow to generate energy.
  • Electricity must connect to the ground/complete the circuit to flow.


The power wire is attached to the fence rail(s) and the ground wire is attached to the ground rods. They are not connected so the power cannot flow and generate energy. Therefore, the power is inactive until there is contact with the fence. When an animal touches the fence, it is like a light switch, connecting power to the ground and completing the circuit. The complete circuit allows power to flow thereby generating energy. As the power passes through the animal, it receives a shock.
