Yake ouzo put on the boiler. ELV for a water heater: prices for the outbuilding of the heating connection and the reasons for it.

Some of the most important electrical safety equipment for the screed in the apartment or private booth is to install and add two main types of protection. The first is automatic fading, yak zahivayut merezh vіd short flickering and shifting. Another element - ce attachment zahisnogo inclusion(ELV) that I take care of safety human life in the event of an electric shock at the time of dotik to the strumovidnyh parts, or viniknennya strumіv coil. Particularly important is such a zahist among the apprentices promoted vology, then by the bath room. Therefore, we report on the power supply, how to choose the ELV for a water heater or a cleaning machine.

How does ELV work and why is it necessary?

First of all, you need to know the difference between ELVs and automatic vimics.

The automatic machine is the main defense of life. At the time of overshooting, at the moment of overshooting, or a short hum, switching device responding to the displacement of the struma and joining, vіdsіkayuchi emergency lot that ryatyuyuchi all the way through the poshkodzhennya.

The main function of the ELV is not to defend the merezh, but the people and the reaction of the attachments to the small magnitude of the streak. How do you feel?

Our booths at once have a great number of different things by-button technology, and deyakі fit to dosit great exhaustion. At electrical wiring the term of exploitation is not eternal, but the more you work with a robot, then the possibility of getting out of the way of isolation was more inscribed. Poshkodzhennya і insulating ball with z'єdnannya wiring іz the ground, as a result zmіnyuёtsya ruhu struma path, now vin vitikaє on the ground. And in some cases, a person can become a conductor for a stream loop.

More about the principle of work, I will add it to the video:

Modern machines and water heaters are driven by technology with advanced energy class. The maximum intensity of the stench is taken from the period, if the TEN is used and the water is heated (about 3-3.5 kW). For electrical wiring, the need is even greater, as it can be used in front of the old insulation.

Let's say, at the right machine, there was a break in the insulating ball, after which the body leaned against the pressure. Having bumped into cars, a person can drink a lot of electricity.

To protect yourself in a similar situation, and it is necessary to set the ELV for the machine.

When a strum coil appears on the ground, connect it and attach the voltage supply.

In the meantime, the ELVs are connected in one lansy sequentially, and the principle of yoga division is based on the variability of input and output values. Ideally, it is necessary to reach zero, so that the size of the stream has gone, so it has left. As soon as a turn is seen, at the exit it will be shown more, less equal to the size of the stream, which follows a different path. Vidpovіdno zmіnitsya vimіryuvana ryvnitsya. Like only a strumovy wind is at the reach of size, on the basis of the repayment of attachments, it’s possible to join in the same time.

There are no special folding facilities near the connection. At the circuit, there is an automatic switch, after a new ELV, from the outer contacts of some kind of darts, it is possible to save up, so that the power outlets for the heating machine or the boiler.

Features of the installation of difavtomativ

If you don’t want to install an ELV and an automatic machine for a cleaning machine or for a boiler, you can replace two switching devices with one extension. This is the most popular differential automaton, which, having taken a wide zastosuvannya in electric butovіy merezhі.

Attachment is combinable in one building and will be subdued by air and ELV, and machine gun.

Difaavtomat maє one nedolіk, tse nayvischa price. To that very person, it is enough for him to have two sets of consecutive switching devices (EPS and a great automatic switch).

Ale varto only reveal, skilki need automatic equipment and ELV for the bathroom, as in some places there are roztashovuyutsya and a cleaning machine, and a water heater, and an electric boiler. And in private booths, the most common accommodation is from the hospital, de є pіch. What can be a rozpodilny shield, so that you can put in yourself such a small amount of automation? It can be done so that there is no place for all attachments on the din-rail. Therefore, it is recommended to put on a heating machine, a boiler and other auxiliary equipment near the bathroom, an automatic difavtomat.

For that against ELV or difavtomativ on the upcoming video:

Parameters and characteristics of difavtomativ

To determine whether the ELV is to be installed for a cleaning machine or a water heater, you should first be familiar with the main parameters and characteristics of the attachment:

• Depending on the fact that a difautomatic device (single-phase or three-phase) is installed in such a measure, a bipolar attachment is selected (on operating voltage 220 V) or chotiripoleusne (380 V). Caution that the nominal working voltage of the obov'yazkovo is to be shown on the building of the annex.

• Nominal strum. This is the value of the stream, as it is measured in amperes, as you can pass through the switching device for a long time of yoga robots. The standard range of nominal streams looks like this: 6, 10, 16, 20, 32, 40, 50, 63 A.
• Hour-strum characteristic (“B”, “C” or “D”), this parameter reflects the latency of the machine’s spratsovuvannya vіd strum, which flows through the new.
• Nominal differential strum. This is the value of the strum coil, on which the difautomatic device will turn on. Also, there is a standard range of differential stream - 10, 30, 100, 300, 500 mA.
• Nominal turn-on capacity. This parameter is the maximum value of the stream of a short zamikannya, like a differential automaton of the building switch-on and the last one in the working station is left out.
• Temperature range. Vin, as a rule, varies from - 20 degrees to +45.

All these parameters are indicated on the housing of the building.

There you will find the connection diagram, the rated frequency of the electrical circuit (50 Hz), the type of installed ELV (electronic or electromechanical).

So differential automatics are used in three types of fallow in the form of a stream coil, to which stench they react:

• "A" - for variable sinusoidal and constant pulsating forms of struma.
• "AS" - for a variable sinusoidal jet coil.
• "B" - for variable sinusoidal, constant pulsating and rectified forms of the struma coil.

Vibir I will add a zahist

ELVs are selected on the basis of the higher characteristics, but do not forget to wash the bathrooms (advanced water).

Give priority to the outbuildings of type "A", which reacts to changes in that constant strum. Irrespective of those that in our electrical circuits have a sinusoidal wind strum, modern technology is equipped with special life blocks on electronic heating elements. For the quarter of which sinusoid snake struma at the block, the liveliness is transformed into a pulsed period. And if the coil is of such a nature, then more cheap attachments of the “AC” type do not react to it and do not work.

Carefully take a look at the passports for the heating machine and the water heater, if you decide to buy the ELV.

For the equipment itself, which is installed at the bathtub, the pickers indicate the type of the required outbuilding, most often “A”.

Deyakі differential automatic mayut at the constructive vikonnі datkovy block, for the help of which it is necessary to turn on the helpers when shaving the net of the zero dart.

You are not inspired by that which you can independently choose zahisny pristry, then break for a purchase in a trading network, yakі mayut a good reputation. Qualified sales consultants will provide you with the necessary assistance, tell you which brewery should win, and choose the right approach according to your financial capabilities.

Faults

Not the only fluctuations, if the ELV when the water heater is turned on or the right machine is vibrated. On the price є low reasons:

• faulty water heater itself;
• installed PZV chi difavtomat not match the parameters of the electric line;
• there was a short flicker at the cord of life;

• poshkodzheno dvigun, block of life or TEN;
• installation of PZV for a prying machine or a water heater for crushing with pardons;
• in the electric circuit, there were tension streaks or a strum coil.

The butt of a joke and the elimination of one of the malfunctions, when vibing the ELV of the water heater, on the video:

If you choose correctly and install the ELV on the boiler and the heating machine, then you will secure the operation of the equipment for the early hours and the heating of the water for a long time, you will save the flow of stream winds and spalah. And the most important thing is to protect people from getting hit by electricians. So think about the zazdalegіd zakhist, so that later we didn’t have a chance to take the blame.

There is a large number of outbuildings automatic switch-on. Under the hour of spratsovuvannya stench protect buttovі attach, Electronics and navіt ryaut life. About those, yakі tse fit, why they are special, pluses and minuses of vikoristannya, how to choose the right attachments, recommendations for the installation of UOA for boilers, you can find out from the article.

The principle of work and I will add an automatic switch

The choice of a special attachment for automatic switching is important and docily in the fall, if a lot of electrical appliances are used in the dwelling at once. Іsnuє kіlka vіznоvidіv avtomіv vіkhisnogo vіklyuchennya:

• automatic vimic;
• extension of a differentiated connection;
• automatic differential vibrations.

Attachment of a shut-off connection (PZV) - we will improve the development after a flickering hour, damage to the integrity of the wiring. At different retailers electric struma the switch-on equipment cancels the power supply. This design is not good for protection from short flickering, sharp voltage drops. I will actively try to build a zahisny connection in our hour for the obviousness of a large number of expensive equipment even Bazhan.

Differential automatic vimikachi (DAV) - allow for some functional features of ELV and AV. The building of the differential automatic vimicach based on the danger of shifting in the electric circuit and the danger of strum strikes against the part of the strum-like outbuilding.

How to choose the right automatic machine

Schob razbiratisya in іsnuyuchy raznomanіttі designs and choose vіdpovіdny, next memory:

• automatic vimikach protects the conduction of the lighting system;
• differential automatic switch protects the rosette part of the merezhі: refrigerator, computer, oven.
• miyuchі pobutovі attach owennі mother vlasnu vlasnu socket and іndivіdualny avtomatichny vimikach z differential zakhistom;
• the power of possession is necessary to connect to automatic vimikacha.

The automatic vimic will need to be installed on the input. The protection of the rosette line is secured by automatic switches with a differential protection.

At the same time, if in the skin booth there was a lot of expensive used equipment and electronics, the wiring is of great interest and automatically switched on more importantly. Savings on zasobah can lead to such serious consequences, like the loss of an expensive possession. Ale naytsіnіshe - human life.

Sphere of victory

The attachment of a zahisnogo vyklyuchenny vikoristovuetsya in electrical engineering with a voltage of three hundred and eighty twenty volts.

ELV is vikoristovuєtsya for zabіgannya blow strum. The order of cim attachments protects against vipadkіv spalakh through poor wiring, damage to integrity, malfunctions in attachments. In practice, it has been proven that the very attachment of a zahisnogo inclusion can turn the life of a person with a dot to a strumming part of an attachment.

In the literature on the protection of practice and safety technology, there is information about the influx of the singing force of the struma on the human body and about its reaction:

• the power of the struma is close to five milliamps;
• non-admission (spasmodic clenching of the hand on the object) - about ten milliamps;
• paralysis of respiratory organs - close to thirty miles amps;
• irreversible processes - internal bleeding, a heart dent - about fifty miles of amperes;
• lethal kіnets - with the strength of the struma, close to a hundred milliamps.

Zdіysnyuvati zakhist sіd vzhe vіd force ten mіliampere.

There are two main categories of ELVs:

• electromechanical;
• electronic.

In order to correctly set up your choice on the singing device of the sound connection, take two main parameters to the point of respect:

• nominal stream;
• strum spratsovuvannya.

ELVs can be checked independently or in parallel with grounding:

• at mobile electrical installations;
• in stationary installations for the safety of zahistu for an hour of work with hand-held power tools;
• on installations, which have zero zeros.

The area of ​​congestion of outbuildings in the event of a threat of impacts is surrounded by a strum. Massively widened constructions there, where there is a problem with current-carrying parts of mobile phones electrical installations, manual electric tool that one is similar.

Vimknennya zdіysnyuєtsya svidkodіyuchim zahisnym mehanіzm, sensitivity and svydkіst viperedzhaє avtomatichnі prilady - vimikachi.

How to pick up an attachment for a boiler switch-on

At the end of the boiler period, the attachment of a zakhisny switch-on is invaluable for intimidating electric shocks.

Boilers, yakі vikoristovuyutsya at once, sіd divided into two types:

• storage boiler;
• flow boiler

From side to side electric shock important є zdatnіst spozhivannya natuzhnostі and principle dії. ELVs are selected spiraling on two factors: the pressure of the water heating system and the difference in water intake. Install as a boiler equipment for grounding, ELV to allow people to be protected by a person's strum. When the ELV is connected, the grounding will not act as a binding aid, but its presence will be the power of the electrical protection system. When the boiler is different, the ELVs are more expensive, lower grounded.

For an accumulative boiler, it is necessary to add sixteen amperes and ten milliamperes or ELV sixteen amperes and thirty milliamperes.

For instantaneous water heater what do you represent to the great trouble of the electrosacist at his side. An ELV of ten milliamps is recommended.

Connecting the ELV to the boiler is necessary for the following reasons:

• zabіgannya blow strum;
• electrical overheating;
• change in corrosion.

Installation

In the future, I’ll build it up, don’t call for difficulties. There is a special rake on the shield
open for the elements of the machine.

The manager will attach a power supply to start the supply of an electric strum for an hour when the strum is punched onto the body of the accessory. The grounding circuit is the same. The stinks are blasting the system different ways ale kindly add one to one.

If the ELV is installed for a one-level zakhist, then for which a tight machine is selected. Such a scheme is compact and simple. Ale minus є those, scho ELV spratsyuє for malfunctions of one of the devices. And z'yasuvati, what kind of attachment can be difficult. When you come, you will change the leather attachment.

If the ELV is set up for a bagator-vnego zahistu, then the design variability is richer and more cumbersome. positive sideє those that emergency situations it is not the whole apartment that is streaked, but the okrema is autonomous. It is important to establish differentiation of vimikaci on such plots near the apartment:

• at the bathrooms;
• in the kitchen;
• at the basement;
• in garages.

The price of such a system is expensive, but you pay for your peace of mind, comfort and safety.

Sometimes, when connected, pardons are traversed:

• interweaving of conductors - the system is spratsovuvannya without objective reasons;
• amateurish connections sometimes causing violations of safety standards, if the jet is connected incorrectly through the boiler, you can hit and susidiv;
• Incorrect neutral grounding and grounding in bypass ELV, which can lead to unsafe voltage in the attachments.

You can look at the photo in the article to see how to correctly connect the connection to the boiler connection.

Follow the memory to install the machine next to the specialist. Even though there is no possibility of speeding up with the help of an electrician, the following recommendations should be made:

• I’ll get enough automatic machines and outbuildings for a shutdown. It is necessary to remember that the vimikach is guilty of buti trying for the machine gun. ELVs may be rozrahovane in magnitude, yakі become unsafe for the health of that life of a person.
• With a large area of ​​​​the apartment and a foldable dotsillnishe, install two fittings for a shut-off connection, otherwise on one ELV there will be a pardon for spratsovuvannya.
• At the bathroom next to install the ELV, the threshold for switching on is ten milliamps.
• The installation of a differential vimikacha in front of the lichnik was fenced off with a method of obstructing an unauthorized electric fence.
• ELV for sockets will require the installation of a sixteen amp circuit breaker.
• For the safety of the system, install a two-pole automatic machine in front of the lichnik.
• Connecting the ELV to ensure that the instructions and instructions are completed will be written on the body of the accessory.
• Differentiation vimikach is guilty of roaming in a place inaccessible to children and unknown people.

I'll build a boiler shutdown

Razmezhovuvat spozhivannya elektrika that not perevantazhuvat system to help the attachment of automatic heating of the water heater. A set of accessories - a transformer, which at the same time from an accumulative capacitor, is connected by a diode to a vimiruvalny vuzol. The design contains the following elements:

• transistor;
• intermediate resistor;
• coil shunt;
• light lamp;
• zener diode;
• potentiometer.

When the voltage rises, the resistor's lance is activated, Tena's release is observed. Svіtlodiod tells about it with a light bulb, which it has blown. Ignition of light to talk about the supply of electricity to the water heater through the automation of attachments. At the time of the exit from the fret of the boiler, the wines begin to work for the help of a bipolar switch.

The design of the shut-off switch is intended for automatic connection of the technical equipment to the electric circuits after the admissible indications of the electrics have been increased. ELV and the guardian are aware of the fact that the guardian spratsovuє when short flicker, and ELV pіd hour for the transition of the electrician to the body of the attachment. Іsnuyut attach, scho mayutnіst zapobіzhnik and pristriy zakhisnogo vіklyuchennya.

The rule of functioning is clumsy: equalization of indications of the input and output streams, with a difference of thirty milliamps, the lancet will automatically open the ELV.

Among the reasons for which it is necessary to install a septic connection for a boiler, they are seen as follows:

• zіtknennya people with a current-carrying part;
• zіtknennya people from the "earth";
• damage to the integrity of the insulation;
• substitute conductors;
• the input of "zero" is that dotik people with a stream-guided part.

From the onset of reasons, it is necessary to spratsyuvannya I will build:

• zbіy at the system zakhistu;
• replacement of conductors.

It is impossible to repair such a folding system on your own, like an attachment to a zahisnogo inclusion. To repair the necessary professional knowledge. In most cases, the attachment is not repaired, but replaced with a new one.

Lowering the energy efficiency of the boiler is even more important nutrition, as it damages the skin's electrical power.

To save money on heating, change the amount of water and water to trim such clumsy rules:

• use the protіkannya, like so;
• install special plumbing with a minimum water intake;
• choose the right shower cubicle with stained glass water no more than nine liters per piece;
• install aerator;
• take a shower, taking a bath;
• replace the accumulative water heater with a flow one;
• robiti insulating materials two meters of pipes each to supply and supply;
• change the temperature of heating water;
• see the siege, systematically pouring out all the water;
• add a boiler with programming functions for heating water;
• install thermal pastes.

Attachments of automatic switch-on help to save power in case of sharp haircuts and help to save life and health in case of non-standard situations.

It is recommended to test the attachment of the connection once a month, testing is carried out for the additional test button, which is placed on the attachment itself. To finish pressing її and at the same moment the situation is created for a round of strum, the attachment is guilty of mittevo to spratsyuvati and to join.

One of the largest possible reasons, vibivannya ELV pid hour of operation of the water heater Termex or Ariston є:

• Ten's insulation collapsed. The problem lies in the fact that its surface became non-adherent, as a result of which the nichrome spiral, as it was in the middle, came into contact with the water in the tank. How to reverse, what problem caused the breakdown of what? If you pull the TEN and clean it from the scale, with a visual inspection, there may be commemorative cracks. To solve the problem, it is necessary to replace yoga with a new one.
• Possibly, there is a coil of struma at your electric meter. The reason could be the old age, in which the insulation broke down, and the dart became naked. Another reason may be inaccurately wired when replacing wiring. It is also possible to damage the integrity of the wiring when the structure is fixed on the wall with flowers, dowels.
• Wrong ELV connection, because of what you posterіgaєte incorrect yoga work that often spratsovuvannya.
• Possibly, with the provision of ELVs you have taken the device for an inconspicuous tension, in the wake of which it is necessary to periodically spratsovuvannya
• Viyshov out of tune with the mechanism itself, it is possible to trap the button to the test, or else the mechanism of the descent, which is spratsovuє in the form of vibration.
• Incorrect placement of DWT in the electric circuit.
• Dotik of bare wiring with a water heater housing so it can itself be the cause of why the machine is vibrating. Tsya injustice lies in what is on the darts, what is in the boilers, the insulation has collapsed, there is a danger of breaking the struma and spratsovuє ELV. To fix a malfunction, choose a boiler and turn it over to the boiler. In the event of a dart with damaged insulation, replace it with a replacement, or replace the insulation with an additional insulating line.

When choosing a defense, there are two options - PZV or a difavtomat, we can try to look at the pluses and minuses of both.

Difaavtomat є Z'єdnannya ELV with a machine gun. Vykoristovuєtsya for zabіgannya coil strumu, and preventing rewiring, її damage under the hour of zamikannya.

How to connect ELV correctly.

Recognize the same information when choosing, operating and maintaining boilers (water heaters) of all manufacturers of manufacturers, you can, if you want to go.

There is specific information on the site, so you can find out specific problems of other people on this topic, if you have already bought a boiler (storage water heater) and in this way you can get rid of them. You will find a list of such problems that pop up regularly, and you will know their solutions.

Іsnuyu two possible options connection:

• Connected to an outlet. Tsya connection scheme is possible for extensions with a small nominal intensity. Another important mind can be manifestly grounded in this rosette, and when installed at the bathroom, it can be watery. If the attachment will be sufficiently large, the socket will become hot, as a result, the gap between the plug and the socket will become weak, there will be a gap in the contacts and spark.
• Connected via additional copper cable, connections directly to the electrical panel and ELV equipment. For such a scheme, a plug and a socket are needed, and the warning will be for the help of an automatic vimikach (machine), for the help of which a water heater will be called, and the guard will be put on the guard.

The main managers of the ELV (attachment of the zakhisnogo vyklyuchennya) є zahist vіd razhennya electricity. Yogo robot walks in a steady stream of phase current zero conductor, with increased prices

vіdbuvaєtsya rozryu lanceug. When choosing which one to install, two values ​​are reversed: the power of the struma (it is recommended to choose three more for the value, lower the automatic) and the value of the second turn, which does not exceed 30 mA. To install a boiler, add a type A or type G. In Denmark, a lot of products are presented on the market, but the next thing is more important, such as Legrand, ABB, AEG, even if not varto save on safety.

The main mental safe and reliable service of the boiler is the correct connection to the electric power supply, with the smallest number of con- stant elements. Must be connected to the accompaniment of the accompaniment to the minimum water intake, krіm pіd'еdnannya drot without intermediary to the water heater. Himself the best place arrival electrical panel all the elements are installed in the new one.

Z єї problems and not only, you won’t know anywhere else, what specific people ask, yak anywhere they couldn’t take more support and advice (what stinks themselves tell us). And in a different way, these problems of the flooring are foldable, that for an hour our expert Oleksandr Kholodov deals with people for 10 and more days.

And now the SKIN nutrition is coristuvacha and it’s good for a new one, so that penny stains are lost due to improper operation or repair of the boiler. And here it is not important that the equipment of a virobnik company takes a part in nutrition. Less important is that unique situation, after all food chain vinik, for how to say one good order: "like a delay, it means an outbreak."

Set the ELV to 10mA nominal strum not lower than 16A (so your ELV can be set).
Why set the ELV to 10mA read in the tables at the bottom of the post. Having read it, you can set it to 300mA - you can’t save anything.
After 5 years, in order to better clean up the uzo, read the table below again and replace the ELV or repair the washing machine / boiler / wiring.

I support, dopomig with a choice)

The nature of the injection of electrostrum on the body of a person:

0.6-1.5mA

Zminny strum- Weak stinging, tingling of the skins under the electrodes
Constant strum- Don't get carried away

2.0-4.0 mA

Zminny strum- Seeing the struma rose up on the wrist, slightly moving the hand
Constant strum- Don't get carried away

5.0-7.0mA

Zminny strum- Bolovі vіdchuttya posilyuyutsya in the wrist, accompanied by vessels. Weak pain - in all hands. Let’s try to fix the vessel’s shortness of the m’yaziv and squeeze your hand, into a squeezed electrode
Constant strum- Weakly noticeable heating of the skins under the electrode

8.0-10mA

Zminny strum- Severe pain and judgment in all hands. Important, but you can cut your hand off the electrode
Constant strum- Stronger visible heating of the shkiri

10-15mA

Zminny strum- Pain, that the ice is transferred, at all times they are overcome by an hour. It is impossible to tear your hand from the electrode
Constant strum- Even more powerfully, I will heat up like under electrodes, and in the adjacent areas of the shkir

20-25 mA

Zminny strum- Hands paralyze mittevo, it is impossible to destroy them. Severe pain, breathing difficulty
Constant strum- Even more powerful heating of the shkiri, due to the appearance of internal heating. Insignificant shortness of my hands

25-50 mA

Zminny strum- Even stronger bіl in the hands of that breasts. The breath is very difficult. With a trivial overshoot of the strum, paralysis of the breath can occur, or weakening of the heart's activity with ease
Constant strum- Seeing a strong heat, I hurt that judgment in my hands. When the hands are blown into the electrodes, they blame the pain that the ice is transferred, after the judiciary speed of the m'yaziv.

50-80 mA

Zminny strum- The breath is paralyzed in a few seconds. The robot's heart is broken. With a trivial overrun of the struma, heart fibrillation may occur
Constant strum- Seemingly strong superficial and internal heating, strong pain in all hands in the area of ​​the breasts. Difficulty breathing. Hands cannot be broken through the electrodes through a strong bіl at the moment of breaking the contact

100 mA

Zminny strum
Constant strum- Paralysis of breathing with a tribal overrun of the strum

300 mA

Zminny strum- Same day in less than an hour
Constant strum- fibrillation of the heart in 20-30 s; in just a few seconds - respiratory paralysis

Over 5000mA

The breath is paralyzed negainno - in a few seconds. Fibrillation of the heart does not stop, it is possible for the timchasovy zupinka of the heart to pass through the struma. With a trivial overrun of the strum (a few seconds), important opiks, ruynuvannya fabrics. Usually fatal

For the necessary installation of outbuildings of a zakhisny connection in the areas promoted insecurity shocks with an electric strum chuli, maybe, mustache. However, there are a lot of electricians, the middle of them are often stunned and professionals, it is not possible at the double-wire barrier, which means either to expensive modernization of electrical barriers in the premises, or to the introduction of ELVs is known.

However, such a lead is wrong in its very essence, even if there are only two contact roses on the ELV, and keep the wire that is grounding, just nowhere! The same principle of operation of similar outbuildings does not require a connection to grounding.

Підоторджує ЦЕ не тільки Dana Stattay, ale І Silent Vipadkіv, Kolya PZV pіdeneki to Trihah Provіlki ryezhі in Yakiy є Groundedhenny Zіlkom cosliki cosyo funny, navivo not diluted to the sickwide grounding (thoughts, urviche entangle) Fingering Викуєї.

It is possible to connect the ELV without grounding

As we have already figured out, the ELV can be set for a special two-wire connection scheme, where only phase and zero are present. I, for greater accuracy and brief understanding of the need to install an additional defense, let's be significant, as a pratsyuє ELV, and after that - imagine a typical situation on the butt.

In fact, the ELV can be entered with your own "calculator". ELV connection diagram without grounding it is even simpler - through the attachments to pass the phase and zero wires, navantazhennya on some relativly it is observed and porovnyuetsya.

In times of poor wiring, or slower in electrical circuits, they are called strum coil - that strum, which winds through poor insulation. The magnitude of this strum is too small - tens and hundreds of milliamperes - but sufficient for the head of a serious, healthy person.

From the same time, the attachment of the zahisnogo connection of the povrivnyu strum, which passed through the phase and zero darts, and, at different times of the difference in these values, the contacts are opened, while interrupting the supply of electricity to the poshkodzhenoy yard of the merezhi. From the theory, let's move on to a whole sensible situation.

For example, you have a bathroom installed in your house cleaning machine. Wiring double-wire phase and zero, no grounding. ELVs have not yet been set. Now you can see that the car's insulation and phase wire have failed, becoming stuck in the metal body of the car, tobto. the metal body of the machine leaned against the strain.

Now you go to the typewriter and stick to the body. At this moment, you become a conductor and an electric stream passes through you. The electric strum will run through you, the docks won't let the metal case through. And in the meantime, you are shaking and b'є in the stream, which is leaking, and nadії on zahist, which does not allow you to turn on the poshkodzhenka. Hope here only on the power of willpower (otherwise you will fall into a trance).

Yakby Bulo ELVs set then when the metal case was torn, which leaned against the pressure, then the ELV instantly took off the wind of the struma and spratsyuvalo, turning on the poshkodzhenu board.

Why? That is why for the first sign of the "skew" of the strum on the phase i zero dart the automatics would have worked and the machine would have simply lost its firepower! And the person would sooner or later catch a light rag in the tee and more would sleep with the resounding clatter of the relay for peace, lower with inaudible sounds.

Moreover, this hour of laying is not enough, because a person is practically not familiar with an electric stream. On the Internet, there is a video from the testing of ELVs, so the axis there is a person who specifically takes on the exposure of wires to the annex of a shut-in connection, a person stumbled on a dart - ELV mitteva spratsyuvalo (vintage is not aware of the discomfort).

How to connect ELV without grounding

I am following the very principle of the work ELV obov'yazkovo need to be installed, Independently, in addition, you have grounding in a booth. In addition, since you have a two-way system of living, then it is more necessary to install an attachment for a septic connection. Do not listen to the joys that, having moved out in such a measure, it is not practicable, but it is constantly spratsovuvatim.

Z power chi pratsyuє ELV without grounding, I'm spodіvayus, razіbralis. Now in front of Tim Yak Zrobiti ELV connection without grounding I would like to tell you one important moment.

The specialty of the outbuilding of the zakhisny connection is the zakhist in the revantazhen. That is why it is necessary to combine them with the great "automatic machines". With this, the connection scheme can be different.

Іsnuyut, zahalom, two options. You can put one charcoal ELV on the whole house, thereby making sure to wind the light fixtures yourself. Ale, only an outbuilding, building let through yourself 40-60A cost a little more expensive for less straining brothers, that and at times spratsovuvannya relay z'yasuvaty the reason will be foldable - you will have to change the skin of the electric appliance.

Until then, the inclusion of electricians in the mustache booth immediately causes a lot of unhandledness - careless documents in the computer, a “hanging” air conditioner, a water heater tank, which is turned on, otherwise the machine is right - you can resurrect it for a long time!

If you failed to install one ELV for the entire group of survivors, then the ELV connection scheme without grounding looks like this:

Another option is to install an okremnogo, less sweating ELV on the skin from "unsafe" lines: bath, basement, garage, kitchen. In such a time, more free space is needed in the shield, that price of three-chotiryokh outbuildings will be higher, lower one, and tighter - the power system’s power system will move up, and the reason for the switch-off will be superfluous.

Dosvіdchenі elektrika razhdat so very brazenly pіdіti і to choice of tension ELV- there can be a little more, a lower automatic machine, which we stand with him at the par.

The reason is simple - the automatic switch from the windshield is far from overwhelmed (for a few seconds to dozens of minutes), and the overshoot of the nominal stream that passes through the ELV can cause a breakdown.

ELV connection at the double-wire fence

Deshcho rozpovіm why I virіshiv write about such a topic as a connection ouzo in the double entrails. I chose this topic not in a vipadkovo way, because I bumped into the same food for me.

Until recently, having lived near the apartment, de wiring was triprovidna (Novobudov's house), tobto. if there is a phase, zero and grounding. And recently I moved to my new apartment, in which the electrical wiring is two-wire, the same zero. good guide RE i close to mute.

Trochs having settled down, having looked into the shield, some kind of rotting on the maidanchik of the yellow zakhist, I didn’t have direct ERP chi difavtomativ, there were only a packet vimikach for 40 A, a lichnik and two new automatics for 16 A each.

Why did I start the topic about connection of ELV at the double-wire fence Let's make a report at once.

Bentezhiv me the fact that the bathroom has a boiler (water heater) installed, which is powered by one of the 16-ampere automatic machine (boiler with a heater of 2 kW).

Moreover, the installation of this water heater is, in the end, inaccurate: we will throw the power supply with a cable, the cable will pass by the bathroom, without looking at the corrugations or the box.

If you take a shower (as it was said in the movie “Moscow Don’t Believe in Tears” - vibatch for such intimate details.) the whole cable at once from the boiler is covered with water (condensate). The druzhina, obviously, this fact is not bentezhiv, the fact that they won’t understand in these food, but it was even more alert. Axis why I have installed the ELV at the double-wire line.

Later, there were two automatic machines in the shield, from one bula the whole apartment was powered (illumination of that socket), from the other it was only a boiler. Trohi thinking, vystanovit on the skin line for your own attachment of a zahisny connection: except for the ELV on the sockets and the other for the ELV is not a water heater. Although it’s splendidly trohi vitrano ale, all the same, it’s safe over the mustache.

Moreover, I wanted to divide the mesh, tobto. connect to the okremy automatic sockets near the apartment and okremo osvіtlennya. And for hanging it was necessary to pull an okremy cable from the shield to the apartment.

At most, in order to get away, stretch the cable from the shield into the apartment to the first switch box and turn on the lighting only in the front, in the other rooms, turn on the lighting in the cable, there is no possibility, because all the wiring in the apartment is walled up. That is why the lighting of those sockets was left behind to sit on one machine.

For the connection, I will add a shut-off connection, choosing the IEK brand of the VD1-63 series, with a nominal jet of 16 A and a differential jet of 30 mA.

I already wrote in the article pardons when ELVs are connected, that it is not possible to add zero after ELVs. At the shield, the connection is made in such a rank that the phase goes through the machine, and zero is taken from the body of the shield. For connection ELV see through the cable of life from the automatic vimikacha (phase) and from the metal part of the shield (zero).

Having installed the ELV at the shield, we proceed to the connection. On weekends, I will add a switch to connect the phase and zero to the live cable (for an apartment up to one ELV, for a boiler to another).

At the input of the auxiliary switch-on phase, we start the output terminal of the automatic switch, at the input of zero, we take zero from the shield body. In this order, zero wires lived, as if they appeared from the ELV and go to the apartment no longer get along with other zeros (there is no connection with the body of the shield).

The connection of the vikonano can be reversed by the attachment of the wicked connection, as if it were done in a robot, so that there would be no place for pardon in case of an incorrect connection. For which it is necessary to turn on the machine in front of the attachment of the power supply and, especially, the attachment itself, then we will create an advancement (plug in the attachment to the outlet). If you don’t see the connection, you can make sure that all the connections are correct.

Also, do not forget that after connecting the difavtomat or ELV, it is necessary to check them for a turn. How to convert the ELVs for spratsovuvannya at such a time? Well, for the help of the TEST button.

For which, when the attachment is turned on, they press on the button, for example, when pressed on the button, it will immediately turn on - it means correctly. The axis is so on a special butt I have connected the ELV without grounding.
