The easiest way to ground wire:
1. The first is to prepare a copper or aluminum wire with skin, and then connect the jack contact of the ground wire at one end, and connect the other end directly to the earth. If the mobile socket is connected to the ground wire, then you have to connect an iron nail at the head, and you can use it when you plug it in, but you need to pay attention to the ground wire when the power is on.
2. The second is to use steel pipes or other metal pipes, buried in the ground as a ground wire, as for the choice of which metal pipe needs to be judged according to the resistance of the underground, and then the distribution box and each socket are connected with wires, so that the ground wire can be grounded.
3. The third is to use various conductors, such as iron rods, copper rods and other tools to bury them in the ground, and the buried depth can be used as a ground wire at a depth of one meter four. If you want to act as a neutral line, you need to drive about two meters into the ground.
Correctly connected ground wire, in addition to our daily electricity protection, can also be used as a "lightning rod" in thunderstorm weather, can prevent lightning strikes, especially some tall buildings must use the ground wire, and if necessary, it should be used in combination with the real lightning rod, so that lightning disasters can be better avoided.

The simplest method of grounding the wire is as follows:
Tool: Wire.
1. Adjust the multimeter gear to the range of 750V of the AC voltage range, and if it is an automatic range of the multimeter, it will directly hit the AC voltage range. Then pick one of the three live wires and measure them together with these two.
2. Adjust the multimeter gear to the range of AC voltage gear 750V, if it is an automatic range multimeter, it will directly hit the AC voltage range. Then pick one of the three live wires and measure them together with these two.
3. Measure the voltage between the live wire and the neutral wire, and the voltage between the live wire and the ground wire. If it is a 380V three-phase power supply, the live wire should be 220V for both the neutral and ground wires, but there is also a difference between the two readings measured, and the value of the zero line with a slightly larger value corresponds to the ground wire with a slightly smaller value. It is also possible to measure the voltage of 2 wires to ground, the neutral wire with a weak voltage and the ground wire with a voltage of 0.
4. Use a test lamp (with a wire bulb) to put it on one of the live wires and the other two wires, if the light is on, it means that it is 0 line. If the light is on, the leakage switch will jump.

The simplest method of grounding wire is to take a copper (aluminum) wire with skin, one end is connected to the ground, the other end is connected to the earth, and then buried in the earth with metal objects such as steel pipes or angle steel, and the best is to drive into the ground, if it is used as a zero line, it is necessary to drive into a depth of about 2 meters, and then if the above is connected to the lightning rod, a copper plate needs to be added at the low end of the conductor, the surface area is about 40 square centimeters, and the salt is appropriately withdrawn around. The docking at both ends is done. In the device with a fixed grounding grid, it can be lapped with a soft metal braided wire that meets the requirements and bolts or splints (sub).
If there is no grounding facility nearby, you can use galvanized angle steel with a diameter and length that meets the requirements to drive the grounding electrode into the nearby ground, and the grounding resistance must be measured to meet various grounding requirements before it can be used. Electrical equipment is less than 4 ohms, communication class I is less than 1 ohm, lightning protection and grounding is less than 10 ohms, and anti-static is less than 100 ohms.

Summary. Pro, Hello grounding wire is a commonly used protective measure in electrical installation, the purpose is to ground electrical equipment and facilities to protect personal safety and equipment and facilities. Here are the easiest ways to ground the wire:
1.Attach a grounding screw to the metal casing of the electrical equipment and connect the grounding wire to the screw. 2.
Find the grounding wire of the house and connect the grounding wire of the electrical equipment through the grounding wire.
Hello grounding wire is a commonly used protection measure in electrical installation, the purpose is to ground electrical equipment and facilities to protect the personal safety of wide illumination and equipment and facilities. Here are the easiest ways to ground wire:1
Attach a grounding screw to the metal casing of the electrical equipment and connect the grounding wire to the screw. 2.Find the Shenliang grounding wire of the house and connect the grounding wire of the electrical equipment through the grounding wire.
It should be noted that the connection of the grounding wire should be firm and reliable and cannot be disconnected. At the same time, the grounding wire should be separated from other lines of electrical equipment (such as wild Li power lines, signal lines) to avoid dangers such as interference or short circuits. In the process of connecting the late ground wire, the relevant safety operating procedures and standards should also be followed to avoid dangers such as electric shock caused by improper operation.

The grounding wire is a wire with a conductive number of lead, which is used to connect the metal shell of electrical equipment or electrical appliances with the ground to ensure the safety of equipment or electrical appliances. The easiest way to ground the wire is:1
Choose a conductive wire of appropriate material, the length is sufficient, generally choose copper wire or copper-clad steel wire. 2.Twist one end of the grounding wire into a ring, or use a grounding card or grounding clip to connect it to the grounding system.
3.Connect the ground wire at the other end to the metal casing of the appliance or equipment, which can be fixed using fastening screws or clasps, etc. 4.
Make sure that the connection between the grounding wire and the housing is firm and reliable, and avoid loose contact. 5.During installation and use, it is necessary to regularly check the connection status of the grounding wire to ensure the normal operation of the grounding wire.
It should be noted that the specific installation method of the grounding wire needs to be adjusted according to the actual situation, and it is best to consult a professional or operate in accordance with the relevant standards.

Summary. Hello dear, <>
I am glad to answer for you, the simplest grounding wire method is as follows: the first method is to make a grounding wire on the socket of the three ports, the left port is the neutral wire, the right port is the live wire, and the middle is the grounding wire. The second method is to bury iron pipes, copper pipes and other metals with good conductivity into the ground, and then use wires to connect the metal with the distribution box, and then distribute them to various sockets.
The third way is to plug in the ground wire in the middle of the three-pin plug embedded in the wall in a modern house.

The extension for you is as follows: The function of the ground wire: 1. As the connection between the building and the earth, the ground wire can conduct the current to the underground to avoid electric shock.
2. Lightning protection, when thunder, tall buildings are easy to be hit by lightning, but if the ground wire is connected, the current can conduct underground buildings along the grounding wire. 3. Ensure the normal operation of electrical equipment, electrical equipment is easy to be attacked by lightning, affecting the normal operation of electrical equipment, and conducting current underground through the grounding wire to ensure the normal operation of electrical equipment.
Most of the electricity used in life is a single-phase 220 volt power supply, and there are usually two wires at home, one is the live wire, and the other is the zero line. But we have a zero wire, why do we need to connect electrical appliances such as refrigerators, electric fans, washing machines, etc. to the ground wire? >>>More
