I bring to your attention already 84 questions for the heading "question-answer". This question came from the reader Oleg with just such a title (I did not change it). If you have your own answer to the question, then write it in the comments below. I and other readers of my channel will be happy to read it.
I quote verbatim the text of the question itself:
I was going to connect the electric stove. Can't tell "0" from "ground". With the phase, everything is clear. But the other two wires give exactly the same performance. There is the same voltage between the phase and the 1st wire, between the phase and the 2nd wire. The 1st wire and the 2nd wire ring out among themselves. And both wires ring out to the battery.
After considering the issue, I consulted the reader within the framework of my knowledge and qualifications as follows:
To determine the neutral conductor (N) and protective conductor (PE) in electrical circuits, you can use the color marking: for the neutral conductor (N), wires with blue insulation are used, and for the protective conductor with yellow-green isolation.
But relying on color coding in household electrical circuits is not worth it, since there is no guarantee that the electrician observed it in accordance with the requirements of the current GOST 33542-2015, this is rather an auxiliary method, than the main one.Therefore, it is much safer to ring them yourself on the dashboard, here you can definitely determine which wire is neutral and which is protective. For this:
- disconnect all electrical appliances from the electrical circuit, and turn the light switches to the off position;
- turn off the input circuit breaker and disconnect the phase conductor and the neutral conductor from it from the side of the apartment;
- disconnect the protective conductor from the apartment panel;
- connect the disconnected phase and neutral conductors in the apartment panel and ring the conductors at the place where the electric stove is connected;
- the wire that will give a closed circuit with the phase conductor is a neutral conductor - mark it in any convenient way;
- connect the protective (PE) on the shield to the phase conductor and ring the remaining of the two on the socket outlet with the phase conductor to make sure that it is exactly the protective conductor (PE).
But personally, in this situation, I am confused by the fact that both conductors are ringing to the battery, I have the impression that the grounding is done incorrectly. In general, I definitely recommend in your case to invite a specialist who will consider your question on the spot.
