How to fill wall cavities

Digitization offers numerous possibilities for electrical installations in building technology. At the same time, behind the scenes, planning and execution requirements increase, as does the complexity of cable and line routing.

Without proper cable routing, there is no “life through the building”: follow-up work is delayed, construction projects in new or existing buildings stagnate. Automation and modernization, smart technology and a wide range require a structural electrical installation that meets standards, safely and also quickly.

Building technology, domestic technology, technical construction equipment or supply technology implement solutions to all energy-related questions relating to sewerage, heating, power supply and lighting, as well as air conditioning and safety devices. But they also offer concepts for all additional systems for the automation of work processes and for the transmission of data and information in and around buildings.

RAPID PLASTERING OR RENDERING TO PREVENT

Installing a junction box alone does not guarantee safety. The case must be properly fitted so that it is flush with the drywall. Otherwise, combustible materials, such as wood, are exposed to possible sparks.

No not if you are plastering the junction box, this does not comply with wiring regulations as the wires are not identified in a permitted safe zone, so do not attempt to conceal this termination.

2 answers. You cannot cover any junction box that still has active wires. Your best bet is to remove the case all together or just put a cover plate on it. If there are active wires in the case, sooner or later you will have to get to the case again, which you can’t do if you have covered it!

You can simply use tape over the high voltage cable to fit the cover. However, it is important to terminate the cable in a junction box and avoid burying the wire in the wall. Tape can come loose when temperatures change and potentially become dangerous.

Electrical installation before or after plastering

When building a house, everything is decided at once. If we talk about wiring, in addition to the panel diagram and wiring plan, you must decide when the electrician should be carried out: before the plaster or after. For those who can not decide what to do first, we suggest reading this article.

The thickness of the sand-cement plaster layer can be from 1.5 cm to 7 cm. A layer of 2 cm, in principle, will be enough to cover all the cable lines. At the same time it will save on strobes and grooves during subsequent finishing.

Strobing in this case is often more difficult than using smooth plaster or cement plaster. The price depends on the materials, for example, bricks or concrete blocks, solid, while aerated concrete partitions are literally scratched with a screwdriver.

When installing podrozetniki, it is important not to make mistakes when laying them flush with the rough wall, as after plastering they will be too recessed. Therefore, the wires are laid along bare walls, the wells are made for socket boxes, they are installed, but not fixed, but are made after the walls are leveled.

Grooving and placing box and polyduct for an installation.

Well the question is that I would like to know once and for all if the current REBT admits or not to place the wiring before executing the coating (plaster, mortar, etc). Table 10 of the ITC-BT-21 is a bit confusing or I am not clear.

Octopussy: thanks, I do not allow it either, but the question is not to know what each one does (or rather what the ignorance of installers allows us to do) but to be able to justify the decisions with the regulations ahead, because after all, if they are personal interpretations you could find an installer who does not swallow.

Here what it literally says is that the chases for the cables must also “chase” the trim and then the plastering can be done. Logically, when doing the plastering, we cover the pipe. As this was obviously not done, what we really did was to trim and plaster and then wire.

jucama198, if I don’t reason it is simply because the REBT does not pronounce in that sense and therefore, the conditions of execution are marked in the project. As there is no rule that prevents our decision the installer is not that he has or not to swallow, he simply has to do what is contemplated and collected in the project, which for more inri and so that there is no doubt, is a coletilla, along with other facilities, we usually put in plan, so you do not have to look for it in the useless and useless pages that the CTE requires us to write once submitted the discussion.
