How to ground the wire correctly, how to ground the ground wire correctly

The first method is to make a grounding wire on the socket of the three ports, the left side of the mouth is the zero line, 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 method is to connect to the ground wire in the middle of the three-phase plug Thai ding head embedded in the wall in a modern house.

The fourth method is usually to connect a wire to a small iron box (with metal grounding inside) on the outside of a normal building.

The fifth way is to dig a pit in the ground at home, and then put the iron plate into the bottom of the pit and weld a steel bar out.

At home, there are three wires in the home, the ground wire and the grounding wire, and the grounding pile in the middle of all three-hole sockets should be connected to the grounding wire of the home with no less than two wires with a cross-sectional area, and no circuit breaker or any other device that can cut off the line can be set up in the meantime.

In the project, in addition to the terminal is also connected, the grounding wire should also be connected to the metal object buried in the ground, which can be piled with angle iron park iron, and also connected to the foundation reinforcement.

The specific operation of the correct grounding of the ground wire is as follows:

Tools: grounding wire, three-pin socket, high-power electrical appliances.

1. Three-hole socket, the left is connected to the zero wire, the right is connected to the live wire, and then connected to the grounding wire, if there are high-power electrical appliances, such as refrigerators, washing machines, etc., the metal shell can also be connected to the ground;

2. Take a copper (aluminum) wire with skin, one end is connected to the ground wire jack contact, and the other end is connected to the ground. Note: Do not touch the ground wire when powering on;

3. The ground wire is grounded, buried in the earth with metal objects such as steel pipes and angle steel, and Bailijia Electric is selected according to the resistance value of the ground, and then connected to the distribution box with wires, and then distributed to each socket. The rest of the operators can operate according to the specific situation;

4. After the above are connected, use a copper-clad steel of appropriate size to drive into the ground, generally 1 is the best. If it is used as a neutral line, it needs to be driven to a depth of about 2 m. If the upper part is connected to a lightning rod, you need to add a copper plate at the low end of the conductor with a surface area of about 40 square centimeters, and sprinkle some salt around it appropriately (to increase the ionic reaction).

Use one end of the wire to connect to the ground jack contact, and the other end is buried in the ground. A metal pipe is inserted into the ground, and then the distribution box is connected to the socket with wires. Use a conductor to bury directly into the ground to a depth of about one meter and four.

The ground wire is a line in the home circuit, and it is also an extremely important one, it constitutes the last line of safety in our circuit, which can make us safer when using electricity, so it is the top priority to install the ground wire in the home circuit.

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.

Hello, the grounding wire refers to the wire used for the grounding of electrical equipment or ICBC transport tools, and its main function is to establish a safe and reliable conductive connection between the metal shell of the equipment or tool and the earth to prevent the occurrence of electric shock danger and infiltration. Here are some ways to ground the grounding wire. 1.

Grounding via plug: For appliances or equipment that have a grounding plug, a socket with a grounding wire can be used to ground. Insert the plug into the socket with a grounding hole and connect the grounding wire to the grounding terminal on the socket.

In this way, the grounding wire can form a closed loop that grounds the metal housing of the device or tool. 2.Direct Grounding:

For some equipment or tools that do not have a grounding plug or require additional grounding protection, other grounding methods can be used directly. For example, grounding wires can be attached to specific grounding points, ground pipes, or metal materials such as rebar on a metal enclosure, and then connected to the ground through these materials to achieve grounding protection. 3.

Use a Grounding Rod: A grounding rod is a tool specifically used for grounding electrical equipment and typically includes a long, thin conductor and a grounding clamp. The grounding protection of electrical equipment can be achieved by inserting the grounding rod into the ground and clamping the grounding clamp on the conductor of the equipment.

It is important to note that the grounding work of the grounding wire must be carried out by a professional to ensure safety and reliability. In addition, in the grounding process, it is also necessary to follow the corresponding national standards and electrical safety regulations to ensure the quality and use of the grounding wire.

The simplest method of grounding the wire is as follows:

Tool: Wire.

Step 1, adjust the multimeter gear to the range of AC voltage gear 750V, if it is an automatic range of the multimeter, directly hit the AC voltage range. Then pick one of the three live wires and measure them together with these two.

Step 2: 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 fire wires, and measure it carefully with these two bridges.

Step 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.

Step 4: Use a test lamp (with a wired 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 wire. If the light is on, the leakage switch will jump.

Grounding wire precautions

1. The ground wire cannot be connected to the zero wire, and it is impossible to use the three-phase five-wire power supply with the lightning protection grounding wire, and the earth wire can be used as an anti-static grounding wire.

2. The grounding wire is used in yellow-green like a sensitive and slippery one, and the grounding main line is generally brazed and connected, and the grounding wire connection terminal should ensure reliable contact, easy to assemble and disassemble, and various clip-on connectors are allowed to be used, such as the key clamp and plug socket.

3. The cross-sectional area of the grounding trunk line shall not be less than 100 square millimeters, the cross-sectional area of the branch line shall not be less than 6 square millimeters, and the cross-sectional area of the grounding wire of electrical equipment or other work surfaces shall not be less than square millimeters of multi-strand plastic-coated wires.

The process of the grounding wire is as follows:

1. When hooking the ground wire, the ground end of the ground wire must be connected first, and then the ground wire must be hung on the wire. The procedure for removing the grounding wire is the opposite. The grounding wire connection should be reliable, not slow and quasi-winding, and it is not allowed to use a short route that is not grounded.

2. When the multi-layer Fubi power line erected on the same pole is connected to the ground wire, the lower wire should be hung first, and then the upper wire, first the wire that is strong from the human body, and then the wire that is far away from the human body.

3. In order to ensure the personal safety of the operator, when installing and disassembling the grounding wire, an insulating rod or insulating gloves should be used, and the human body is not lacking in any way to contact the grounding wire or ungrounded conductor. It is strictly forbidden for staff or other personnel to move the grounding wire that has been hung up at will, and if it is necessary to move, it must be agreed by the work permit holder or the person in charge of the work, and it must be indicated on the work ticket and cargo safety measures ticket.

4. The grounding wire is composed of 1 grounding section and 3-4 short road sections, and the grounding wire must be made of multi-strand soft and bare copper wire, and the single area shall not be less than 16mm2, and it is strictly forbidden to use other wires as grounding wires.

<> first of all, the three-eye socket should be grounded separately, the left is connected to the neutral wire, the right is connected to the phase wire or the live wire, and the reliable metal shells such as washing machines and refrigerators are also grounded. Use steel pipes, angle steels and other metal objects to bury in the ground, specifically according to the resistance value of the ground to select, and then connect to the distribution box with wires, and then distribute to each socket. The ground wire of the family, the three-phase plug of the wall is the ground wire on the top of the wall alone, some old buildings do not have a ground wire, it is best to take it apart to see, if that makes no phase wired on it.

If it is a factory, a Tenkena-like power distribution cabinet has a ground wire, as long as it is connected to the main body of the cabinet, the outside of the building is connected to the underground metal objects, some are steel bars, some are steel bars, if you are a bungalow, you want a ground wire, you can dig a long 50 cm deep pit in the house, channel steel or iron plate into the bottom of the pit to weld steel bars or steel bars, pull out of the pit and fix it on the wall after connection, and then use the wire to access it if you need it indoors.

Ground wire is properly grounded method

1. When the three-eye socket is grounded, it needs to be fired on the left and right, and for electrical appliances with reliable metal shells such as washing machines, the grounding wire should also be used. In addition, when the ground wire is grounded, it needs to be covered with metal objects such as steel pipes and then buried in the ground, and then the wires are connected to the electrical box, and finally each line is connected to each socket separately.

2. For the home ground wire, the three-phase plug used on the wall belongs to the ground wire, and for some older buildings, it has no ground wire, you can disassemble it to check some, if there is a wire in the phase, it is the ground wire.

For factories, it is equipped with a power distribution cabinet, so there is a ground wire, as long as it is connected to the main body. For bungalows, you can dig a pit about 50 cm long when grounding the wire, and then put the channel steel into it, connect it and then fix it.

Distinguish ground methods:

1. It can be distinguished by a multimeter, and the connection with the black and red watch pen. If there is a reading, it is usually the live line, and if there is no reading or the data is small, it is the zero line. And if there is no value, it is represented as a ground wire.

2. If you want to distinguish between the neutral line and the ground wire, you can distinguish it according to the leakage protector of the house. Since the key function of the leakage protector is leakage protection, when the current above the live wire enters the ground, it will feel that it is leakage.

At this time, the electric switch will be broken, and the other 2 wires can be connected in place, and then the switch will be pushed up. If the protector's indicator switch pops up, it means that the ground wire is connected. If it works normally and does not trip, it means that the zero wire is connected.
