Protective shutdown in electrical networks is the most efficient. Its use will securely protect you in case of malfunction in electrical appliances and directly in the power grid itself. One of the devices that perform this is the most protective shutdown is the RCD. Disconnection occurs when the current begins to flow in the network to the ground. This may occur if there is a breakdown in the electrical appliance on the body, or when a person is touched to the current-side part, with the old wiring, if weak isolation.
1
Now there are so many different types of UzOs that differ in parameters and characteristics. Therefore, before buying a protective device, you need to decide what parameters you need it. When choosing, focus on the load current on your network. At 1 A load should have 0.3 mA of the nominal current of the protective appliance. It is required that the Uzo is in working up to five seconds when the voltage drops in half from normal.
2
When installing the RCD, you need to make the device to be located as close as possible to the electrolynee input. The best option will be the installation of the UZO immediately after the electric meter. It is placed, like protective machines, on a DIN rail. When you connect the wires, look at the alphabetic marking. There at the entrance and exit there are letters "L" and "N". On the "L" of the input, connect the phase wire that comes out of the electric meter. On "N" input - zero wire exit from the electric meter.
3
The phase wire that comes out of the Uzo, connect to the input of protective automata, and zero from the Uzo - on the terminal block in the shield where the zero wires of the network are suitable. This terminal block must be on an isolated basis, and it cannot be touched on the shield body. Wires with work zeros should not come into contact with zeros protective.
4
It is impossible to turn over or mount sideways. If you change its position, unauthorized triggering will occur or even loss of working capacity. When the UzO is triggered, the current should be disconnected, on operating conductors, including zero conductor.
5
The UDO device is not designed to shut down when overloaded, and it works only when the leakage current appears. Therefore, a shared automatic protection must be mounted in the shield, and after the Uzo, there are automata automata to shut down and protect individual sections of the network and certain electrical appliances.
Summing up, we want to note that in the presence of many electrical appliances in each house it is worth thinking about additional security and worry about installing a protective device of the RCD.
Hello ! I have long been engaged in Uzo. Since 1999. I had to install a lot and I had to search for a lot of current leaks to the ground to force the RCD to work steadily. I have had a long-term instrument for this, the astro is called. I had a device for measurements and tests of the UZO. Called astro-pro. All my works did not turn out to be in vain. The man alone thanked me for the fact that he once saved his life and the health of the UZO installed by me! For a long time I am conducting verbal battles with some people who are against the Uzo that with the ground that without it. In particular, today I wrote a comment on the "Electric AC" site, where they are discussed by the topic of the UDO installation in two wiring. I wrote a lot before, but they did not publish a single commentary. Here is such a democracy! Only once published, but at the same time intentionally, terribly endured the whole point. I give you the last time of my appeal of electric toovtsy. Let's see later publish it or not?
Yes, I wanted to do with you and Pue! Since you are pests in a place with the authors of Pue !! I personally two times the Uzo went from the wire and the hull of the shield under voltage !! To my friend, I put the UDO in the two-wing. He was clogged under the water in a close basement and stood an electric pump connected with a well-rubber hose (0.5 meters). In his house he stood a switch to a pump bursting a phase to the pump. So went two years old. Electricians of the electric grid replaced the supports of the VL along its street and confused on the input of the phase with the zero !! ...... That is, it began to turn off the zero on that pump through the switch, and the phase turned out to be incomprehensible to the electric pump !!! And then it is later as it climbed into the basement to serve or check this pump. The switch it means prudently put on the "off" and being sure that he would not hit him (he did the same) so much) it means something to straighten the pump to holding both behind the support, for the metal wet borehole pipe. Well, drove hand to the naked terminal of that pump. As a result, he received a blow to the current and electricity instantly turned off the UZO !!! He got out of the basement in full darkness, but well alone !! If it were not for the Uzo, he would not be able to release the pump independently and the well pipe and help him had no one !!! The man would die, as well as I could perish in my two cases !!! The Uzo saves life and without ground, but by itself that with the ground it works more efficiently. This and fool clear! In connection with all this, in the authors of Pue and on you who support their pest idea are the blood of the dead people who might save the Uzo !!!
