Behind the rules of the Rules, I will build electrical installations, all electrical wiring, which is newly sporadzhuyutsya, mayut additional conductor. It is called a wine guide (PE), which is marked with dark brown and green colors.

Zahisnі conductors are connected to the housings of electrical appliances and connected to them by the ground loop. Pobutova tekhnіka: computers, prying machines, electric stoves, low-frequency ovens - are connected from the input conductors through the contacts of the sockets.

When testing the insulation of the butt fittings, their cases show under tension. When in contact with the body of a damaged accessory, a person will be hit by an electrostrum. Navmisne z'ednannya corps from the ground in case of a breakdown of the insulation to cause a short flicker until the vindication, like turning on the device to zakhistu, and if possible, suddenly strike.

Navіt like a strum will be insignificant and the inclusion will not be, with a dotik of a person to the body of the strum through yogo tіlo matima value, unsafe for її life. The body of a person can be opir from tens to hundreds of thousands of ohms, and the opir of grounding conductors is selected from a few ohms. To that strum through the body of a person will be significantly less than the strum that goes into the ground through the guards.

Krim zahistu people, grounding the hulls by attaching the screen to the electromagnetic fields, which are used by them in the process of work. Tse lowering the price of the change, which is important for the robots of other devices.

Protected conductors cannot be connected to the zero busbar of the electrical panel. The old electrical wiring is shilni up to shavings at the lancets of zero conductors, the result of which will inevitably appear on the zero wire of the current potential of the “earth”. The value of the potential can reach 220V and, if you lean on the body of the accessory, you are in for a serious injury.

The vikoristanya has been fenced off as zahisnih conductors of gas pipes, scorched pipes and sewerage. It is not possible to wink with the method of water supply pipes, the shards of de stink are scraped with metal.

For connection of conductors of grounding, a grounding loop is required.

What is a ground loop?

The ground loop is a group of electrodes, hammered near the ground and called vertical grounders. Mіzh itself stink pov'yazanі horizontal grounding with additional zvaryuvannya. The horizontal grounding device should be placed on the wall of the building, or else without being in the middle at the entrances of the rozpodіlny attachments.

For the preparation of vertical earthing machines, vicorous steel coils or pipes are used, and horizontal steel coils or a round profile. It is not possible to farbow, otherwise the electrical contact with the soil will be weak, and the circuit will be efficient.

If there are booths near the warehouse structures buried in the ground, the stench can also affect the function of the ground loop. The stench is called natural grounding.

How to zrobiti grounding?

There is nothing foldable at the prepared grounding circuit and you can build it independently.

For whom you need:

• for vertical grounding: a coil or pipes with walls with a torso not less than 4 mm or fittings with a diameter of not less than 14 mm;
• for horizontal grounding: steel smuga with a web not less than 100 mm 2 and a torso wall not less than 4 mm;
• for introduction to life: thick or flexible wire with a tread not less than 10 mm2;
• tools Cabin: shovel, grinder, sledgehammer, zvaryuvalny apparatus.

The order of work for the installation of the ground loop

1. Digging a trench with a depth of about 0.5 m and a width of 0.5-0.3 m. The length of the trench is about 5 m.

2. After 1-1.5 m at the trench, grounding machines are hammered with a sledgehammer. To ease the process of grounding, it is necessary to use a grinder.

3. Grounding workers squat among themselves for help. The end of the smugi is brought to the wall of the wake, or, as it is possible, to be introduced until the wake is closer to the shield. A bolt is welded to the smuga for connecting the conductor, which is grounded.

4. It is better to fertilize the trench in the trench, so that the seams in the earth are quickly crumbling.

5. Smuha is called and in the middle of life is farbuetsya smugs of yellow and green colors, which are blacked out.

6. Before that, like a trench, it would be inappropriate to vimiryati opir otrimanogo contour. Fight with special tools. If opir will be insufficient, supplementary electrodes will be clogged and the wife will join. І so until the necessary value is reached (trochs are more than 4 ohms).

If you fit something that is not available to you, use your abilities and a healthy mind with the specified number of electrodes. Electricity is needed richly, as a soil of food and even more, as a substitute for the soil - succulent stones. On the Black Earth, 5-7 electrodes are used to obtain good results. Do not sip on the ground loop. The conductivity of yoga is improved, ale and zgnie vin shvidshe.

7. Seal the trench with soil without a wake-up call.

8. An additional bus is installed at the shield - PE. Vaughn is led by a conductor of yellow-green color from the ground loop. Now it is possible to connect all the cases of electrical appliances with the PE bus.
