Do-it-yourself grounding in a private booth

Do-it-yourself grounding at a private booth will help you to escape the safety, and save your budget. Aje electric strum can lead to wrongful health, the life of a person. In case of an emergency, bring the dot to the ultimate cleaning machine, or the micro-furnace can lead to tragic consequences. If there is a shaving of the zero phase, then the body of the electrical equipment becomes unsafe, its ground loop is like a phase, like an electric jet goes to the ground.

Installation of grounding is a necessary entrance for whether it is a private house, a rich apartment or a cottage. To avoid short circuits, and also for the safe operation of any electrical appliances, grounding is simply necessary. How to zrobiti grounding? The voltage of 220 volts and 380 volts depends on a different approach and the difference between the two, in fact, two different measures. At a voltage of 220 V, it is possible to carry out a standard grounding without lining the circuit, but for another option (380 V), the ground circuit is bound.

If you have any trouble, if you install new wiring, or you try to reanimate the old one, the installation of grounding can be broken.

Ground loop - help to conductors

Let's figure out what the ground loop is like: the vertical grounding machines are actually buried, but the grounds are connected horizontally. A grounding conductor is added to the design, the main function of which is to protect the circuit of that electrical panel. In accordance with the rules for the construction of electrical installations (vidannya No. 7), for vertical conductors it is recommended to use a steel coil (50 × 50 × 5 mm - ideally fits), for horizontal conductors - a metal smugu (with a straight-cut crossbar, size 40 × 4 mm). The grounding conductor is made from a round steel bar with a rebar of 8 or 10 mm². The exact parameters of the grounding elements in the report are described by the rules for the installation of electrical installations (PVE) - division 1.7

When describing the metal elements, the thought of fitting fittings arises - which work is categorically impossible! Reinforcing rods to wash the surface of the hardened ball - this factor disrupts the even passage of the electric jet along the cut. This material is also resistant to oxidizing, corrosive processes.

How to robiti grounding - installation to the circuit

On the back of the hand, the outline is: for which handrail from the booth (not moving 1 m above the foundation) on the ground, there is an equal-femoral tricutnik. Let's sweat along the borders of the tricutnik, so having cut off the trench, the depth of 1 m will be enough. The width of the trench must be such that it would be possible to carry out the digging work by hand (0.5-0.8 m). On the perimeter of the tricutnik, horizontal groundings are laid on the back, after which vertical tracks are driven in along the ridges to a significant depth - 2 or 3 meters. It’s easy to work for help with a sledgehammer, for the clarity of the process, it’s better to sharpen it yourself at the end.

Now we install the ground loop. Vemogi so: the edges of vertical grounding can protrude by 25 cm from the place of burying. To close the circuit, weld horizontal grounding to vertical ones. The zadnannya of the details were duly carried out exclusively for the help of the brewing apparatus and not otherwise. After that, the circuit is attached to the electrical panel: a berm steel drіt (retin 10 mm), it is welded to the contour, it is laid in a trench to the shield, a bolt M6 (or M8) is welded to the end of the dart - the screw is necessary for fixing the dart. If you don’t have a steel rod, then as a grounding element, a steel smug can be vikorated (it was also vicorated for the preparation of horizontal groundings).

Zgіdno z practical dosvіdom, steel smuha is more suitable for grounding, lower drіt, prote її fold neatly in the necessary places of the trench. Do not fill up the brewery with special anti-corrosion measures, smut - for no reason do not beat the natomist for the great farba! The metal parts are due to borderline contact with the ground, and the farb ball crosses the contact, creating an opir. After all the manipulations with the trench with the earth, on which process of cladding the contour can be completed. All the descriptions above are also zastosovuyutsya when installing bliskavkozakhistu - the process of concurrency.

Okremo varto guess about the ready-made grounding kits (for example, ZANDZ, KZTs-5, KZM-3, KZM-10, KZM-20), as they are sold at the electric equipment. Such a grounding kit already has all the necessary details for cladding the system: wire pins, straight head, tip, clamps, brass sleeves for grounding, as well as special anti-corrosion zasib. It is worth making a smart decision, because when you buy this kit, you take away all the necessary elements for yakic grounding.

Connecting the electrical panel - the final stage of grounding

This process is the responsibility of conducting the qualifications of a specialist or, prinaymni, a person, as previously repeatedly small right with a similar work. For beginners, who know about the installation of grounding a bit or “wandering” the Internet about the stages of the process - let's get it right by learning the theoretical part - it's impossible to beat it. Until then, do it right, it is necessary to be put more seriously, so that if there is any wrong krok, it will threaten your life, healthy.

For that month, when the contour comes out of the trench, it is necessary to install a separate box on the wall of the booth. In the middle of the box, the tire is mounted from two fasteners for bolts. The earthing circuit smuga is connected up to one wire, until it is necessary to connect a copper cable, it can be cut more than 10 mm². It is important that the cut of the cable is smaller, lower the span of the introductory wire. Instead of fastening with bolts, it is possible to vikoristovuvaty zvaryuvalny apparatus for z'ednannya tsikh parts. After that, it is necessary to lay the copper cable to the shield, then connect it to the ground bus. Vіd tsієї tires vіdkhoditimut mustache grounding rods. The main mindful process of increasing the integrity of the grounding cable at all stages of laying is the fault of the whole, not the mother of the cracks. Re-verification of grounding, vimir yogo, the support is stored for the rest of the stage of the entire process.

Private booths can have different-phase electrical connections, so grounding 220V and 380V can be separated. However, it should be checked that the stench can be straightened onto one circuit. Sometimes on different forums you can make comments about the fact that for a 220V line it is not necessary to cover the ground loop, you can zero it. It’s true that it won’t, but it’s still not possible to open the circuit for 220V electricity supply.

If you yourself conduct grounding 380, then the appearance of the circuit is obov'yazkovoy umovoy. Power transmission 380V is even more powerful to the ground loop.

How to reverse grounding

The revision is carried out after all installation work has been carried out. For which there are special accessories (for example, Extex GRT300, TH200, EP183M), the process of rechecking the grounding is the same for them. In front of you, dig two pins (the clay can be no less than 50 cm), clean the litter on the tire. Then, according to the instructions, what to add to the accessory, conduct the appropriate color to the ground bus and to the pins. Wimіryuvannya to be carried out as the instructions for fitting. Zgіdno z PUE showed a support for electric 220V is not guilty of changing the Chotirioh Ohm. Before the ditching of the pinnacles, cross over, so that underground communications do not pass in any place.

The phase in the socket can be reversed with the help of a special tester, it can only be done in one of the sockets. Before the hour of rechecking the grounding contact, the light-indicator of the tester is not guilty of burning, if it does not burn, it is also necessary to check the correctness of the connection, or it may show a fault. When the sockets are plugged (naturally, when the electrician is at fault, but it’s turned on), there are three wires, maybe two of them, and between the terminals (zero-grounding) there is a jumper - this is an indication that it is grounded, but not grounded. If everything is set up correctly, all three rods are in their place, then the socket closes, the electrics turn on, for the help of a multimeter, the phase-zero voltage, phase-ground, zero-ground voltage is reversed. If there is no voltage at phase-zero, then it can be used to cut off zero voltage, if there is a voltage at phase-earth, then it means that there is no grounding. Even if the phase-zero and the phase-to-earth are spiking, it is elastic, but if there is no zero-to-earth, then, obviously, it indicates zeroing.

Even though you don’t have any suitable vimiruval fittings at your fingertips, but if you need to reverse the grounding, you can use the old reversed method - a light bulb with a cartridge and two wires. It is necessary to clean the ends of the wiring and insert it into the socket, the light bulb must be on. They gave a trace to pull one of the wires and touch it to the ground, as if the light bulb did not work, then by such a rite to re-wire the other wire. As a spratsovuє pristry zakhisnogo vyklyuchennya (PZV), tse pokazannosti osnovannostі zagryadlennja. It’s like a daylight, but if the earth-phase is connected, the light bulb is also on, but if the light is richer, it will be richer, lower when the phase is connected, zero.

It is better to protect you from a possible electric shock, and your own equipment from a breakdown. Today, we can’t imagine our life without various electrical appliances, which will make it easier. The electrician is giving us great help, but you will carry a deadly problem, if you don’t know how to behave properly with him. The organization of competent grounding is the most important stage in the installation of any kind of life. As if you were grounded in a private booth with a proper rank, you should know the qualifications of an electrician, but if you take on the right hand with your hand, it will be better, if you are in order, you will be informed of a person.
