How do home electricians wire the ground wire?

Yes or no!

If there is leakage protection, even if there is no grounding, it is OK.

If there is a special grounding wire for residential buildings, you can connect it on it, generally use yellow or green wires as grounding wires, if you build your own house, tap water or other iron objects, the tap water or other iron objects are buried in the ground more than 2 meters underground, and the home grounding wire can be connected!

In fact, you can install a leakage protection! But buy good brands!

Leakage protection: Sometimes thunder will protect itself from tripping! Excellent!

A 63A two-phase leakage protection is within 40!

First of all, the grounding wire should be 4*40 galvanized flat iron or 40*40 galvanized angle iron with a length of 2500mm, a buried depth of about 2300mm, and the resistance measured by the shake meter should not be greater than 4 ohms. All electrical grounding wires are reliably connected to this grounding body and are treated with anti-corrosion. Use the total electricity leakage protector and separate the lighting, kitchen, bathroom, air conditioning, bedroom, living room, dining room, basement or garage socket each has its own independent protector, the selection of the protector is selected according to the load size of each branch through calculation, and the selection of the total leakage protector is selected according to the multiple of the current of the maximum branch plus the current of the other branches.

After selection, the sensitivity and reliability of the action should be tested after the power-on, and it is important to remember to test once a month!

The leakage protector is only used on the socket, do not install the lamp, the lamp is a two-wire system, there is no ground wire, the socket is a 3-wire system, there is a bottom line, if the transformer in your community is a 3-phase 4-wire system, you need to connect the refrigerator or washing machine to the outer skin of the ground wire, or the bathroom and other potentials, if it is a 4-phase 5-wire system, it is not needed. , Beijing 360 Electric Company, hope to be able to help you.

The leakage protector has a high sensitivity, and when the human body accidentally touches the charged body, it can cut off the power supply in an instant of tens of milliseconds to avoid personal accidents. However, many factors, such as the operating overvoltage of the power supply circuit and the induced lightning overvoltage, and the excessive DC component of the current can also cause the misoperation and rejection of the leakage protector. Therefore, the protective grounding wire should still be required.

When the leakage protector refuses to move due to various factors, it can be compensated by grounding protection.

If you don't have a grounding wire at home, it is more troublesome to lay a separate grounding wire.

According to the national standard practice, it is necessary to make a grounding wire system from the outdoors alone, which requires galvanized flat steel and galvanized steel pipes;

According to the national standard practice, a galvanized flat steel is connected from the outdoor grounding wire system and introduced indoors;

Lead all the way to your home distribution box and connect with the grounding terminal in the distribution box;

The grounding wire is complete.

If you want to do this according to national standards, the detailed practice can tell you.

The grounding body vertically buried by the grounding device can be used in a steel pipe with a diameter of not less than 50 mm and a wall thickness of not less than mm, or an angle steel that is not less than 50 mm 50 mm and 5 mm, and sometimes a round steel with a diameter of not less than 19 mm is also used.

The length of the grounding body is generally 2 millimeters of steel pipe. The end of the steel pipe driven into the ground is processed into an inclined shape or flat tip shape, and the one end driven into the angle steel or round steel is processed into a pointed head shape. Before installing the grounding body, the trench should be dug along the line of the grounding body, so as to facilitate the penetration of the grounding body and facilitate the laying of the flat steel and round steel that connect these grounding bodies, and the depth of the trench is generally more than meters.

If the measured grounding resistance is greater than 4 ohms after the construction of a grounding electrode, then 2 or more grounding electrodes should be drilled, and the spacing of the grounding electrodes should be greater than 5 meters. The connection between the grounding bodies is generally connected with a flat steel with a thickness of not less than 4 mm and a cross-section of not less than 48 square millimeters or a round steel with a diameter of not less than 8 mm, and the connection method should be welded.

Weld a steel bar from the grounding body to the ground, the head of the steel bar can be bolted to connect a galvanized bolt or a 3 mm 30 mm 200 mm galvanized pull plate, and then use a square millimeter copper wire to be firmly connected to the bolt or pull plate with screws to introduce it indoors as a grounding wire.

The protective ground wires of all appliances can be accessed from here.

Hello, the home installation ground, with galvanized steel pipe or galvanized angle iron, into the ground at least 2 meters, the joint can be treated with anti-corrosion, galvanized is not rusty.

If one point is too little, you can hit several more and connect them with galvanized flat iron. The grounding wire is introduced to the grounding terminal of the user's distribution box, and the grounding wire of the household appliance shell is connected to the grounding terminal of the distribution box.

The connector connection should be firm and reliable, and a leakage protector should be installed.

The installation of a simple ground wire can be made in the damp place of the ground floor outdoor against the wall to make a 1.5 such angle iron, and then the ground wire is connected to the place where electricity is used, and when the ground subsidence is increased, it can be connected with the metal water pipe and heating pipe at the bottom outdoor against the wall, and a leakage protector can be placed at the same time as the ground wire will be safer.

Hit a grounding pile to do the equipotential deep, it is best to contact the wet soil two-color wire on it, you can also find a round steel or angle steel of not less than 2 meters to plant into the ground, and then make a hole at the upper end of the lead wire is the ground wire.

Find a round steel or angle steel of no less than 2 meters and plant it in the ground. Then make a hole at the top of it, and the lead wire is the ground wire.

1. Dig a small pit in a humid place indoors, and then bury other metals or scrap iron into the ground to ensure that the resistance generated is more than 2 ohms. Then connect the ground wire of the socket to the designed grounding electrode with a wire, and the grounding work of the socket is completed.

2. The standard ground wire is to use a long angle iron with a bottom surface of 5 5cm, and after smashing it into the ground, it is introduced into the distribution box with round steel or wires. Note that when the grounding wire is connected, it is also necessary to connect the air switch with leakage protection to ensure the safety of the later stage.

3. What should be paid attention to in the connection of household ground wire: in the process of connecting the ground wire, it is necessary to install the connector first, ensure that the contact is good, and have enough clamping force to prevent the value of the short-circuit current from being too large, and the situation of poor contact will lead to falling off.

4. It is also necessary to check whether the connection between the grounding copper wire and the short-connected copper wire will be loose, and it is necessary to use screws to tighten it in time. At this time, it is also necessary to solder firmly with solder to avoid the situation of fusing due to poor contact.

5. When installing the grounding wire, it is best to have two people present at the same time, and whether it is installing wires or disassembling wires, you need to wear insulating gloves to ensure safety. Then before the grounding wire, it is necessary to carefully check whether there is any damage, which needs to be repaired or replaced in time, so as not to affect the safe use in the later stage.

6. When connecting the ground wire, it is necessary to use a matching wire clamp to fix it above the wire, and try not to use the winding method for grounding, otherwise it will bury more potential safety hazards.

Household electricity only needs a general grounding wire, the diameter of the ground wire should be consistent with the live wire, the zero line, and 50 mm angle steel or steel pipe connected into the ground. The ground wire is the abbreviation of the grounding device, and the ground wire is the electrical system or electronic equipment, which is connected to the ground, the shell or the wire with zero reference potential.

The ground wire can be divided into working grounding and safety grounding, and safety grounding generally includes lightning protection grounding and electromagnetic radiation protection grounding.

There is a difference between the neutral line and the ground wire, the neutral line is the line drawn out by the neutral grounding of the transformer, and the ground wire is the line pulled out by the building and lead grounding device, and the neutral wire and the ground wire cannot be reversed.
