Where does the gas pipeline come from?
There were no more smokes. When I tried to connect the gas pipeline to the boiler when it was connected to the electric network, it began to spark, which caused me to change part of the gas pipeline to a rubber hose. Currently, the boiler is not working, the board is changing. How can I avoid such situations in the future? Because gas service workers “freeze” from this problem). Thanks in advance.
- Or there is voltage on your “earth”, and since the gas pipeline is most likely grounded, a short circuit occurs or, if you like, a leak.
- There is potential on the gas pipeline, and in the boiler it somehow connects to the body. The result is the same.
You need:
- Decide where you got the yellow-green wire from and what it is connected to.
- If you have a ground loop in the courtyard or under the support, then check all the contacts of the protective conductor (the so-called "metal connection").
- Check for voltage on the ground and on the gas pipeline.
According to. Section 1.7.82 chapters 1.7. PUE “If the gas supply pipeline has an insulating insert at the entrance to the building, only that part of the pipeline that is relative to the insulating insert from the side of the building is connected to the main potential equalization system.”
That is, at the entrance to the building there should be an insulating connection, after which the gas pipeline is connected to the potential equalization system (to grounding). By the fact that you put a rubber hose and you did something similar to this very insulating connection. that is, they removed the galvanic connection between the gas pipeline and the gas system of your boiler.
