Grounding in a private booth, ground loop diagram
The basis of engineering measures for a private booth is an electrician. In order to safely beat the electrician into a private booth required ground loop, the lancers have such a common use of electric appliances.

What is the ground loop
Grounding circuit, regardless of the simplicity of my attachment, richly functional and viconu:
- The defender of people in the form of an electric shock, dotorkayuchis to the wrong electrical appliance.
- Reduces the rate of high-frequency magnetic transitions, which are changed by butovy electrical devices that same engineering electrical system into a booth.
- I will take care of the safe operation of electrical appliances, which are used in the minds of advanced water (cleaners and dishwashers, boilers and flowing water heaters).
- Take away the noise barriers in the electric barrier.
Vlashtuvannya grounding in a private booth
The installation of a ground loop for a private booth, equipped with the rules of PUE and є clumsy in the preparation process.
Folding down the contour without a middle from 3 grounding electrodes dug into the ground and metal construction, which is a visible bus for electrics.
The design of the decals of grounding electrodes is marked by the fact that the area of one is not enough for the creation of the necessary area for full protection and the sprat of electrodes connected between them on the stand compensates for the cost.
important do not spread the electrodes to a large distance, otherwise the surface of the modeled area will collapse, and the efficiency of the ground circuit will change dozens of times.
As a material for the preparation of grounding, it is allowed with the norms and rules of the PUE steel metal with different coatings or lugen and galvanized copper.

Ground loop for a private booth. Scheme
Visota skin grounding electrode, which is mounted in the ground according to the norms of the scheme, may be 2 - 3 meters. The electrics are roztashovutsya at the ground following the principle of a rіvnofemoral tricoutnik with a winding width less than 1.2 meters between each other, according to the rules of the PUE. As a successful element, a metal plate is victorious, as it is superimposed by a conventional method for the removal of an overhead contact between electrodes.
For grounding through the prepared contour in the booths, you can twist (recommended) the same metal tire or steel wire through the cut.
Do-it-yourself installation of grounding at a private booth. Video
How to ground a private booth? Zrobiti grounding at a private booth is enough it's awkward to do it with your own hands. For which you need metal coils with a size of 50x50 mm and a length of 2 to 3 meters and a metal plate with a size of 40x4 mm.
At the selected location for installation robimo rozmіtku rivnofemoral tricutnik zі sides 3m. Behind the spaced armchairs, we make a trench with a depth of 70 cm and we hammer in the kuta along the ridges, as if they will be grounding electrodes.
Afterwards, it is between itself with a metal swarm of zvaryuvannyam and for an additional layer of steel, or a steel rod, pulling the bus of the grounding circuit to the booth. At the station, the grounding lance was rozpodіlu on the booth, robably bolted with a flexible copper wire and rozpodіlyaєmo yogi engineering electrical conduit. We fill the trench with earth and our grounding at the booth is ready.
The process of installing a sound grounding at a private booth is cumbersome. And not without specialization skills, it’s enough to get to grips with the rules of the induced scheme.
And on this video there is one more way, like a vikonati grounding for a private booth in the kit.
Grounding systems for a private booth. Grounding re-verification
The grounding system of the cottage before being put into operation must be re-tested for practicality. System testing is carried out by an electrical tester zamіryayut opіr or as vin is called simple my ohmmeter. For a private booth with connections in the 220 volt range, the opir is not guilty of overshooting 30 ohms.
An ideal option for showing a supportє zero value, to talk about povne poglenannya elektriki earth. Shards of an ideal indicator are practically impossible to reach, therefore, there are standards for the creation of electronics for butt fittings. Pitomy opir is protected depending on the design features of the ground loop, and may have standard values of 0.5, 1, 2, 4, 8, 10, 15, 30, 60 Ohm.
Without being under the hand of the necessary possession, it is possible to reverse the practice of grounding for an additional superb light bulb, by connecting one contact from the phase in the measure, and the other from the ground. The more the light bulb lights up, the lesser support at the ground circuit.
Orientation variant of grounding at a private booth
Koshtorisna vartist for the preparation of grounding in the booth is refurbished from the vartost and the amount of material stained for installation, as well as the vartost of the robot from the storage and start-up of the juvenile robot.
