How to make the installation of hidden wiring under plaster

Hidden wiring under the plaster

When decorating work with concrete, foam concrete, brick or plaster walls of various mortars, hidden wiring first stretch in the furrows, cutting grooves that are specifically prodalblivayut, and then close the overlay crude plaster layer.Cables and wires with double insulation, easier to lay in Stroebe, without using any additional protection.An important disadvantage of this method is that the wire can not subsequently be replaced without the need to breach the integrity of the wall.Electrical wiring, which is made in cable channels and pipes made of materials resistant to burning, does not have this drawback, but this method is much more time-consuming.

Mounting flush in the apartment begins with a markup immediately after the rough finish.It is noted on the walls (ceiling) of the future location of the switches and junction boxes (if used), outlets and lines, which will be held shtroblenie.Next to mount Enclosures, it is necessary to drill the recesses.Enclosures mounted in the recess, which is partially pre-filled with mortar, which has at its core gypsum, flush with the wall surface.The next necessary step that will help to make the hidden wiring under plaster - shtroblenie to the desired width and depth of the previously marked lines.

Shtroblenie walls for guiding his hands

Ideally Stroebe width must match the width of the stacking cable.Then once the cable firmly "held" in Stroebe, nor did he bulged and falls.To put a single three-core flat cable VVG, which has a cross section up to 4 mm2, usually enough Stroebe, 0.7-1 cm in depth. It is forbidden to Stroebe bearing concrete walls.Therefore, to conduct such communications, you must be thick enough layer of plaster nasnosimoy for roughing work.

Enclosures To install, you need to drill a wall puncher, using a special attachment - "crown."

for drilling of concrete walls is better to use the punch with increased capacity, ieover 1000 W, however, having no professional equipment for such purposes can be used and an ordinary household hammer.In this case, you will need one at a tool change.Initially used by the crown.After deepening bits 2-3 mm from the surface of the concrete (more power to the perforator used in everyday life, usually not enough), to replace its drill having a diameter of 6 mm.This

drill several holes drilled throughout the grooves, resulting from the use of the crown.The distance between the holes should be minimal, fully closing the circle.drill hole depth -. 2-3 cm Then again, set the crown, which can already go deep more.Thus, the process is repeated, until you reach the required depth for installation Escutcheon.Then, using a hammer, concrete punctured in the middle, but the hole is mounted Escutcheon.

drilling process often complicated by the presence in the concrete at the drilling site, the steel reinforcement.So, it is better to probe the pre-zone, which is exposed to drilling, using a portable detector.

If you plan to conduct further wiring in cable channels and pipes, then the next step is to install them in the already prodolblennye Stroebe, toward the mounted Enclosures.Then lay cables and wires.The cable channels and pipes the wire and cable tightened flexible steel wire.When performing lektroprovodki without pipes and cable channels, the wire and cable can be fixed directly to Stroebe alabaster (pure gypsum).The wires, which are suitable for Enclosures, tucked into them, and the excess is cut to a length of 10 to 15 cm. Shtroblenie walls under the wiring is completed, now we go to the next step.

flush mounting under plaster

Sockets often assembled into one frame units.This makes it possible to combine in one blokne only electrical outlets, as well as TV, telephone, Internet outlet, and even switches.This will allow them to exploit the convenient, save space and win aesthetically.To mount such a unit needs special latch, namely, cable channels.Their use allows to combine among themselves podrozetnik group follows.

Next resulting group is established in the already prepared grooves.This hole should be drilled in a row and almost dense (the distance between the holes should be less than 1 mm), and the central partition carefully removed.This ensures that the unit can be disassembled and set the whole thing.When mounting and connecting as well as after the metal frames outlets must touch tightly enough.

frames and covers are installed in the final stage of finishing work, when will be pokleit wallpaper or painted walls.When qualitatively work performed frames and sockets cover snugly to the wall evenly without forming any gaps.

To install switchboard flush is necessary to make shtroblenie deepening rectangular sufficient depth, width and height.In the resulting shield housing recess fastened by means of a gypsum mortar.This installation flush is complete, proceed to the final stage.

selection and installation of the switchgear

This step is carried out based on the number of groups involved.Thus, each group has its own machine (RCD) to which they are connected.In addition to the single-pole output machine should have a general and introductory bipolar (single-phase circuit).At one pole is connected phase, on the other - an introductory neutral wire cable.

switchboard Mounting example into three groups, with one reserve.

Having a common distribution board on the landing, which includes all of the metering devices (electricity meters), you can make a connection to a group of machines, the power of which is allocated to this apartment.

If you need to ground the grounding niche (which is part of the shield) is connected to the grounding neutral conductor extending from the induction power supply cable - the so-called three-wire single-phase system.If such a cable, but there is a working neutral wire, it is possible to connect the ground bus to him at the entrance to the opening machine.By opening the door to the zero machine connects zero common bus, which is also part of the shield.

Ability to disable automatic opening, promotes safe working inside the shield, for example, the replacement of the output machine, when leaving them out of action.Installation of meters (electricity meter) is carried out before the output machine, and after opening.This selection and the general switchboard installation is completed.Now you know how to make the installation of electrical wiring hidden under plaster, walls under shtroblenie perform wiring with their hands, as well as being installed and connected sockets and switches in the right place.

Especially for site repair one-bedroom apartment with his hands.
