The article describes the installation sequence of the drywall partition, which significantly reduces the cases of violation of the insulation of the cables laid in it.

In recent years, the popularity of drywall partitions is growing. This is understandable: quickly, efficiently, conveniently. But how to protect the electric cables laid in such a partition, if each square meter of the partition contains up to hundreds of pointed screws (self-tapping screws) that can easily pierce any cable? Laying a cable along a certain route, for example, strictly 20 centimeters from the floor, helps to avoid misunderstandings, but more often this is not enough.

How to lay cables so that not a single screw breaks the insulation when screwing drywall sheets? A standard drywall partition consists of a frame assembled from galvanized steel profiles ...

The TN-C electrical grounding system has long been outlawed and banned for use. But it is easy to ban, but what about those whose homes were commissioned long before the introduction of new norms and rules?

Indeed, for the operating organization, the modernization of the common house wiring and bringing it at least to the TN-C-S system is an overwhelming waste of time, effort and money. And therefore, people living in old-built houses often face the challenge of incorporating modern household appliances into a two-wire network with a TN-C grounding system. And most of the questions arise when connecting powerful devices with a metal case.

The latter relates, first of all, to the electric stove and the washing machine. So, how do you enable these devices in your TN-C home network? The sequence of actions is ...

In general, the question posed in the title is somewhat provocative. Even in technology, there is practically nothing clearly “right”. But then there are frankly erroneous technical solutions. To avoid them, we will try to consider in detail the air input device using a modern and gaining popularity SIP.

Why SIP? So, SIP is a self-supporting insulated wire. He replaced the usual uninsulated stranded aluminum wire, which to this day can be observed as part of the overhead line of the private sector in many regions of our country. Uninsulated wire was used earlier simply because of the lack of reliable insulating materials that can serve in harsh outdoor conditions ...

In the vast majority of cases, when installing a hidden electrical wiring, one can not do without such a dirty and noisy procedure as gating.

Wires and cables must be hidden, but how to do it without a gate, if we just have a plain wall of concrete or brick? Moreover, the bundle of these wires sometimes turns out to be more than impressive, especially in places of connection to the apartment distribution board.

Strobing and laying of cable harnesses must be taken care of long before the final decoration of the room: it is when the apartment does not yet have a trace of furniture, no items, no wallpaper, no linoleum, nothing at all. In a word - bare walls, as in one famous TV show. On these bare walls, we determine and mark the route along which cable lines will run through us. Marking can be done with a building pencil and level ...
