There is some truth in the fact that fashion is returning. In 2023, such solutions have become increasingly common in interiors. At the moment, Americans often resort to this so as not to spoil the finish if it is necessary to repair the wiring. It is very convenient if everything is organized correctly.

Oh yes, this is indeed the reincarnation of a very old idea. Necessity has turned into a fashion accessory:
It is completely safe
If you think that the electric current carries a certain danger for you, then you are deeply mistaken. Now there are special wires that allow you to solve this problem in the best safe way. Their shell has tremendous electrical resistance. Now try adding special mounting boxes to this. All this is laid on non-combustible material. Therefore, even with a short circuit, a fire will not occur. The engineers calculated everything very accurately, and the designers brought it to life.
