Tryabva yes folded RCD for clarification
Once the decision was made to install the RCD for clarification or not, many tend to make a smart device. Tova Chesto justified it from a lipsat to a meat in the scoreboard for clarification.
What is the Kazakh normative document in the basin vrazka? Is there another way to dissuade the scammers on the razporedbite? Please describe in detail on the installed protection devices in the basin.
Containment: 1. Research on PUE 2. Research on other regulatory documents 3. Let's generalize for a while - is it necessary to put the RCD on top of the clarification? 4. Conclusion
Research for PUE
If you ask all of us to the point of necessity, from installing on the RCD for the line, protecting the nests, then the answer was unequivocal - installing it on the protective device is not required. In the case of cabled lighting, there are no directives regarding installation on the RCD above lighting in PUE.

Research on other regulatory documents
Mounting on RCD for clarification is regulated in the Code of Regulations SP 256.1325800.2016 at point 5.4.12. Here we are talking about an installation on a lamp in zone 1 - a commercial space in the vicinity of a sauna or a shower (and there are 4 zones in total, depending on the humidity).
SP p 5.4.12
In time for the installation, the work is strictly limited to the search for regulatory documents. Istinskiyat professionalist yama yes, deviate from tyah, dori ako designer pleasures go izskvat. Nai-important moment when correctly installed on the electrical cabling e lipsat on dori nai-malkata possibility for emergency situations.
According to Tozi, he began to answer the question “Is the Imam in need of RCD for clarification?” you can answer in the affirmative.
Let's generalize - is it necessary to put RCD on clarification?
For the final answer to our question, we will briefly touch on the principle of the action on the device for the remaining current.
The device is for the residual current and the pre-switcher, characterized by a high speed and reacting to the difference in the current path, in contrast to the pre-phase and zero conductor. Preksvacht react itself to svrhtok vjv verigata. From own country RCD reacts to leakage current. Because of the difference between the current wire, which replaces the phase converter, and the neutral conductor, the RCD is not amusingly protected.
Comrade, save your stomach for a man, as the insulation of the conductor is completely damaged. Tokt, sometimes appearing as a result on the dokosvan, maybe even a little bit from tuning to the preksvacha, but it’s enough to do harm to the horat.
Such accuracy is possible due to the fact that the device is based on a differential current transformer or a zero-sequence current transformer.
Figure 1. RCD chain.
Figure 1 shows a component on a security device. Differential transformer ima three windings. Wind 1 and 2 with the connection of the kam disconnected to the phase and zero conductor. Winding 3 - kam relay on the descent.
Samiyat mechanism can be:
- Electronic.
- Electromechanical.
From its own country of origin, it is connected to a place to protect contacts. The correctness of the device is determined from the button test. It is connected in series with the resistor R. The nominal value of the resistance value of this elector, which is foreseen for the current value, is equal to the leakage current.
With normal operation, the current preminava prez phase and zero conductor. Wind the windings with connections on transformers 1 and 2. In winding 3, the magnetic flux is zero, then magnetic currents are opposite in windings 1 and 2, but equal to each other, but oppositely soaking.
In case of damage to the insulation in the protection, it is often wired to pre-winding 2, but now it will become smaller, the pre-winding 1 is broken off (or vice versa). Tova meaning that the magnetic potency on the winding is very different. In response, it was also brought to the current of the winding coil 3. As for the value of the overhead, the value of the value is set, the mechanical engagement and the contact group are also excluded.
When connected to lighting conductors without RCD, it is possible that bets will be made, in some cases it is of no importance. It is possible to assemble the board in such a compact way by using two modules per DIN rail. Goods of all predstavitelnosti, obtained through the intermediary when installed on the RCD.
Some lighting bodies are equipped with metal bodies. Povecheto illuminating the body is fucking dumb. There are two theses, on the right I looked, not particularly due to circumstances, they can and will lead to electrical injury.
If it is laid on the lighting pole, there is a risk of neglect and damage to the insulation on the conductor. Tova e is completely sufficient, for the sake of it, the potential for upper body metal appears. Whenever you choose, take the ashes from a lamp, for example, from a candlestick, with a wet karpa, a man, you will probably get an electric shock.
Another dangerous situation arises from incorrectly connected to a jarzhach on an illuminating body with a threaded base. Option e is safe, when the conductor is phased, the contact is connected to the center on the cassette, and the contact of the rezbat is nullified.
In addition, describe the cases in the mountain, in the stomach, there are other troubles. For example, when it was crushed, the crush of a man burned out unwaveringly to the end from the edge of the end to the cartridge. Tova Chesto is a case in a lamp with a cramped lampshade. Ako finish the end with a roar, ima the possibility of a current strike.
Problem in these cases can be avoided by installing on the RCD for lightening. This device is even better electrically protected, so if you flood the apartment on the upper floor or some electrical conductors, hide under the grease, and damage over time for unsuccessful repairs.
Conclusion
Contrary to what is installed on the RCD for lighting, it is not connected with regulatory documents for rooms with high humidity, for example, baths, showers, etc., it is valuable for all people and their lives.
It’s unacceptable, yes, it’s healthy!
The impact from the currents may not be fun. Whenever tokt preminava prez cheveshkoto tyalo, the trace is known to the time, but there may be a heart failure.
One of the consequences of the currents is a blow to the nervous system and damage to the internal organs. Takiva naranyaniyushchie scho can yes ce will appear with the course for a while. There are many reasons for pain and neurological treatment, but also an investment in time and betting, which is incomparably higher than the price of RCD.
