Electric fences are not connected to the ground in the circuit?

A short answer:
An electric fence is connected to the ground only when an animal or a human being touches it to complete a circuit from the fence to the ground.
A longer answer:
The wires of an electric fence are not connected directly to the ground because, if that was done, the fence would be shorted out and would not be able to do its job!
This is how an electric fence is actually hooked-up: the electric fence is connected to one side of a specially designed high voltage source and the return side of that source is connected to the ground.
Then, whenever the skin of any animal - or human - touches the wire whilst standing on the ground in bare feet, they get a high-voltage (10,000) DC electric pulse from the electric fence. The shocks are designed to be only enough to make them jump back from the fence, not to "electrocute" them so badly as to cause serious injury or death.

Electric fences are connected to ground through a ground rod driven into the ground near the electric fence control. This is one half of the circuit. The other half of the circuit is the wire strung from pole to pole around the field. This is known as an open circuit and no current flows.
The current only flows when something or someone closes the circuit. An example would be a cow in its enclosure, with its feet on the ground, is creating one half of the circuit by way of the ground rod pounded into the ground. All it takes is for the animal to touch the other half of the circuit this being the fence wire to close the circuit. The fence controller senses the closure of the circuit and sends a high voltage DC pulse through the newly closed circuit. Startling the animal it moves away from the fence and hence the circuit resets to its normal open condition.

Earthing is most probably the most important component of an electric fence system. Most of the electric fence problems arise due to poor earthing. For an electric fence to be effective, the circuit needs to be completed. When an intruder or animal touches the fence, the circuit is completed through the ground or the earth wires, The current flows via the earth back to the energizer.

In an electric circuit the ground prevents current from flowing in the circuit true or false?
In an electric circuit, the ground does not prevent current from flowing. Instead, it provides a safe path for electrical current to return to the earth in the event of a fault. It's a protective measure to prevent electrical shock hazards by maintaining the voltage stability in the circuit. The normal operation of the circuit isn't affected by the grounding system.
Can one convert a two prong outlet to a three prong outlet?
Yes, provided that you have a ground wire in the box and that the ground wire is properly connected in the electric panel.
Why is the ground wire hot at all outlet boxes on a particular circuit?
Most likely the ground (green) wire is mistakenly connected to hot instead of the hot wire (black) at the breaker panel! Possibly you meant the neutral wire not the ground wire, in that case most likely the neutral (white) wire is mistakenly connected to hot instead of the hot wire (black) at the breaker panel! In either case check all three wires in the breaker panel for that circuit to make sure they are all correctly connected! Black is hot, White is neutral, Green (or uninsulated in some cases) is ground.
In a circuit what is zero volt rail?
A zero volt rail is a rail that is connected to 0V... What do you think it is? The 0V rail is often used as a common ground, although obviously it relies on your ground voltage being 0V.
Why not hook ground to neutral since they are hooked on same spot in breaker box why not in outlet box.?
The "hot" wire and the neutral wire both carry current (the same amount, in fact) when a load is connected to complete the circuit. The ground wire never carries current except when a fault-to-ground situation occurs. Yes, neutral and ground wires should both be at ground potential, but NO they should not be connected at the outlet.
What is meant by the ground in an electric circuit?
The ground in an electric circuit is the brown copper wire.
Does an electric circuit have a beaker?
Electric circuit need a main circuit breaker that can protect the whole circuit from short circuit even in ground fault. It's safer if you use breaker with built in ground protection.
In an electric circuit the ground prevents current from flowing in the circuit.?
false
What you mean by ground fault?
An electric circuit grounding.
In an electric circuit the ground prevents current?
false
What is open circuit and short circuit?
Consider two points (A and B) in an electric circuit. An open circuit between A and B means there is no electrical connection between A and B. A short circuit between A and B means there is an electrical connection between A and B.
What is floating load?
A load not connected to ground but connected in a feedback circuit is floating load

Which circuit breaker use to prevent against electric shock?
GFCI = Ground Fault Circuit Interrupter.
What will cause electric motor to shock you when you touch it?
The motor winding has gone to ground internally. The ability of the motor to shock you is caused by the ground wire missing or not connected. It is this ground wire that trips the breaker in short circuit conditions and disconnects the motor from the distribution system.
What is a circuit connected to the Earth called?
Grounding?AnswerIf a line conductor is unintentionally connected to earth, then it is an earth fault.
What does short circuit mean?
A short circuit condition is caused by the grounding of the circuit anywhere from the distribution point to the load of a circuit. This grounding causes a high rush of current because of a low resistance of this type of circuit. This high rush causes the over protection device to trip and interrupt the current flow.
