Ground loop: attachment, re-roofing and do-it-yourself installation

If you are planning to buy a high-quality house, you will need to take care of the safety of the electrical wiring. It's not a secret for anyone that in the most important number of private houses and apartments, there is also electrical wiring, more grounding, or vikonan with violations of the rules of safety.

At this level, we need to tell the minds about those how to properly prepare that viconate of the internal installation for the installation of a living energy supply system. Below, a diagram of the external and internal grounding circuits will be drawn, all the necessary materials will be redeemed, and the development of this system will be reportedly described.

What is a ground loop

Zagalom attachments of grounding є kіlka z'dnannyh between themselves conductors, like roztashovanі in the horizontal plane. This design is given by the order of the boom and looks like a large geometric figure, folded from the electrodes. What are the purposes and how to correctly install the ground loop, and also what are the functions of the faults for? Let's remake the main tasks, for which such an attachment is being prepared:

1. Safeguarding the security of the meshkants and defending them in the event of an electric shock.
2. Defender of butt technology butt fittings vіd stribkіv merezhovoї naprugi.
3. Vlashtuvannya zahistu budіvlі or primіschennya vіd hit bliskavkoy.
4. Opir distribution of electrical energy.

Axis for these main functions it is necessary to carry out an accurate re-roofing, as well as the installation of a ground loop. The scheme of yogo folding is even simpler and conceived by the schoolboy, and the main rozrahunok is folded from the designation of the electric wires, which will be buried near the soil. Now let's get down to the installation of this virobu.

How to choose an internal ground loop with your own hands

For the preparation of the contour, steel fittings, coils and steel pipes are most often used to make the grounding function. You can grow up to 3 meters. After that, as the necessary rozrahunok has been victorious, the trumpets are to be hammered at the ground, vikoristovuyuchi for this sledgehammer. Sometimes the contour is poured with concrete, it is not recommended to test it, shards may sometimes be needed to replace other elements. If you fill it with concrete, it will be impossible to repair it.

As the diagram shows, the ends of pipes to the beast are covered with a steel smug, the tovshchina is guilty of becoming less than 4 mm. If you need a grounding loop, lay the smug clods in the front digging trench, approximately 0.5 - 1 meter lower than the ground, after which it is necessary to install a vicorous brewing apparatus with pipes. Here, there is no need for an accurate rozrahunok, it is simply necessary to weld all the steel elements.

With the help of saving money, all groups can be expanded along the perimeter to the foundation, or along the perimeter of the sadibi. Mounting to the ground loop you can easily vikonati with a vlasnoruch, on the chain we call for a short time. Before the finished circuit, which establishes a geometric figure, all sockets and other fittings are connected, which are stitched in the middle of the room. Especially given is the scheme of an important three-phase line with a voltage of 380 volts.

Characteristics of the ground loop: what is poured into them

First, start to hammer the pipes and dig the trenches under the ground loop, it is necessary to carry out in advance the steps to improve and improve the soil characteristics, shards in the form of a support with a stale stale opir and grounding. Tsey pokaznik vzaєmopov'azaniya іz znachenimi lower authorities and factors:

1. The maximum depth of the ground loop is grounded.
2. Mill and chemical characteristics of the ground flooring.
3. Soil type (chernozem, clay and in.) and yogo vology.
4. The material from which the contour element is prepared.
5. The total number of grounding groups and the number of electrodes at the skin of them.

Chernozem, loams and clay soils are the best option for rotting the grounding circuit. At the same time, it is necessary to remember that on the surface of the skel and stone curves, grounding is categorically hindered, shards of stone often carry out a strum, looming low vlasny opir.

Rozrahunok contour ta yogo principle diagram

Before that, for a private booth, it is necessary to familiarize yourself with the elementary rozrahunki and the elaborate design scheme:

1. Vіdstan vіd mіstsya, where the electric cable enters at the booths, before I add the AC circuit, it can become less than 50 meters. This distance is the best option for installing horizontal and vertical electrodes. It is also not recommended to cover the surface of steel electrodes with farboy or with bituminous slurries, the chips will significantly degrade the electrical characteristics of the grounding.
2. To determine the difference between the electrodes and the grounding circuit, it is recommended to use a special table, in which the difference in the value of the fallowing of the material is indicated. The table is meaningful to ask rozrahunok.
3. The entire structure of the contour is selected from steel coils and lines, as if they are connected between themselves by arc electric welding. Under the hour of welding of structural elements, grounding is necessary to reconsider the materiality of their fastening.

The order of preparation and insertion into the ground of a closed circuit is simple and intellect. The back of the head needs to be dug deep into the required depth (sound 70-80 cm). It is very hard to reduce the electric power with all the accessories in the booth, it is better to increase the depth of the trench to 1.0-1.2 meters. The configuration of the row is to make the correct knitting pattern, the sides of which are folded 1 meter. The first step is to start digging a river, rather to make a shape on the surface of the soil.

On the corners of the tricout trench, they zabuvayutsya, as it was described, trumpeting chi kutochok. Vіd іх іх аnurrennya stale op_r to the ground contour. Bazhano, that the length of clogged steel pipes became less than 2 meters. With a high hardness, it is better for the soil to speed up with a drill, and not with a sledgehammer. To the ends of pipes to wash, fasten steel smuga to contact-arc welding. For whom we have a grounding dispute, we will complete it. Now it is not necessary to change the ground loop any more to designate this support.

Dekіlka korisnyh porad, yakі need to vrahuvat when installing the ground circuit with your own hands:

1. Kіntsі pipes abo kutochkіv, yakі will be driven into the soil, bazhano call for help, to make it easier to zanurennya into the ground.
2. The upper ends of the kutochkiv after slaughtering the guilty protrude over the surface of the bottom of the trench by 20-30 cm.
3. A ready-made circuit must be connected with a grounding bus in the middle of the booth, a vicorous cable of a large cut, and it is necessary to squeeze in a clamp for a fire contact.
4. So that the steel was not corroded in the places where the steel was made, it is necessary to thoroughly clean it and cover it with a water-repellent slurry (farba, bitumen).

The installation of the grounding circuit is not required to be carried out on the switch by self-tightening. Navpaki: and rozrahunok, and the installation of the work is simpler, after consulting with the electricians, how to serve the lot. In this rank, it’s easier to take the listeners away for the sake of a warehouse of soil and special features, I’ll build a grounding.

The command of the oval contour does not become a hodgepodge in installation, it simply means physical susceptibility and practicality with the device, as well as. And the axis of the necessary manipulation with the electrical panel is far from being so simple. At this stage, it’s smart to ask for a specialist, who will at once turn over to the robot all the necessary documents in the system.
