I bring to your attention already 81 questions for the heading "question-answer". This question came from the reader Vasily 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 the text of the question itself without changes:
I want to install an electric oven in the kitchen. Panel house. Aluminum wiring. Is it possible to run a separate cable from the electrical panel to the oven in the baseboard? Moreover, the plinth passes / is laid under the front door and under the sink.
After considering the issue, I consulted Vasily within the framework of my knowledge and qualifications as follows:
Where is the shield from which you are going to extend the new cable? Why is the skirting board located under the front door, and why don't you have at least circuit breakers or other protection devices installed inside your premises?
If there is at least a circuit breaker inside, it is better to connect the same line to it, and not stretch it under the front door. With the same success, you can connect in any junction box using terminal clamps.
As for the sink, everything is not so simple here, since according to the requirements Sec. 2.1.56 and 2.1.57 of the PUE current-carrying elements must have a distance from ordinary pipelines of at least 50 mm when crossing and at least 100 mm when laying in parallel.
If pipelines with flammable substances (gas in the kitchen) pass near the plinth, then at the intersection there should be at least 100mm and 400mm with parallel laying. When there are hot water pipelines nearby, the wiring must be protected from temperature effects.
Otherwise, if the skirting board design provides for the possibility of placing the cable in a special cable channel, you can safely lay a separate line for the oven in it.
At the same time, it is important to choose the right cable itself in terms of cross-section and insulation parameters, since it is not in the plinth must overheat, and the insulation must withstand all temperature loads from the flow of electrical current.
