The grounding rod must be galvanized steel and at least 4 feet in length for best results. The use of copper bars reduces the overall effectiveness of the electric fence system. In some cases it may be necessary to add multiple grounding rods to the grounding system.
To ensure the ground rods are in contact with enough soil moisture to complete the circuit, it is recommended to 90 cm (3′) the ground rod below the water table for each joule of power provided install the electric fence device.
wire. Use 12½ gauge, galvanized, high-tenacity wire. Tie the wire properly. For a two-wire fence, the first wire should be 22 inches and the top wire 40 inches from the ground.
Proper Ground Rod
In most cases, pipe or rebar can be used. The grounding rod must be galvanized steel and at least 4 feet long for best results.
This can be caused by a broken ground wire, broken wire or insulator, a loose connection, or something touching the wires such as a wire. B. excessive vegetation. The fault locator can help you locate the source of a short circuit by measuring the flow of energy from the energizer to the ground.
As a general rule, install at least 3 feet of ground rod per joule of output capacitance. A 15 Joule fence charger requires at least 45 feet of earth stake. These poles must be installed at least 10 feet apart.
If the fence extends more than 500m from the main earth, it will be necessary to add an additional earth wire to the bottom of the fence and bury a stake at these distances. Wire is a better conductor than earth, so a ground stake every +/- 500 meters will greatly increase the effectiveness of the fence.
The answer is no, an electric fence does NOT have to make a complete loop. However, there are pros and cons to completing the fence loop. Creating an infinite loop will increase the voltage on the fence line as the current will flow in both directions.
Ground Rod Length
Ground rods come in 8 foot and 10 foot lengths, with 8 feet being the most common size for residential installations. As a rule, grounding rods must be at least 2.40 m long and must not be shortened.
If a single ground has a resistance of 25 ohms or less, building codes allow it to be used as the sole grounding device. If the resistance of a grounding rod is greater than 25 ohms, at least one additional grounding rod is required.
About 90 percent of all earthing systems for buildings are connecting rods. The NEC requires that all driven poles be a minimum of 8 feet in the ground and, for multiple poles connected, a minimum of 6 feet between poles.
Grass or other plants touching your electric fence will reduce the power supplied through the fence line. Excessive grass contact on an electric fence can completely ground your fence.
Summary. With electric fences, the ground wire gets hot because it carries electricity from the fence charger to the fence posts. An improper connection between the ground wire and the electric fence charger can allow electrical current to flow back through the ground wire and cause the ground wire to become hot.
Remember that with electric fences, insulators can touch the fence, the wire can touch itself, but if someone touches the ground and the wire they will be shocked.
For longer life installations, copper bonded ground stakes are best. For many years, the copper cold water pipe has served as the primary grounding electrode for commercial & House grounding.
NEC code specifies that solid copper wire used to connect to a ground rod must be at least either #6 or #8 gauge (depending on the size of your power cord). Cable #6 always meets the size requirements, although in some cases a larger size is desirable.
Two spikes close together are never worse than one spike, but increasing the spacing of the spikes reduces their interaction and results in an overall lower impedance path to ground.
Poor grounding is one of the most common faults in electric fencing systems. If the grounding is not properly completed, the energizer cannot work at its maximum potential. As a rule of thumb: three feet of ground stake for each output joule of energy from the energizer.
