wiring in the home can be overt or covert.The names speak for themselves: a hidden wiring meant that the electrical wires and cables, their mounting and protective structures are carefully hidden in the walls, floors, foundations and floors.

Hidden wiring more reliably protected from external influences and does not spoil the appearance of the walls.However, at the same time, it is more time consuming and Drugs, laborious, difficult to check the condition of the wires and replace them perform without damaging the finish without knowing its location when drilling is possible to get into the wire. Although such a list "but" concealed wiring is used very often.
There are several options how to "hide" the wiring and they depend on the concealed wiring mounted in a wooden house or apartment
Wiring of electrical devices is regulated by the Rules or abbreviated EMP.
According to the EMP hide the internal wiring can be routed in the following ways:
- in pipes, flexible metal hoses, ducts;
- in closed channels and voids of building structures;
- to render over furrows, under the plaster;
- embedment in constructions in their manufacture.
main requirement for the wiring is fire safety.Because of this, to structures made of flammable materials must satisfy more stringent requirements for the flush.
- in wood frame house wires, put in cavities, must be fireproof metal pipes and ducts, which do not allow short-circuit fire.The metal should be protected from corrosion.
should be remembered that in damp areas prohibit the use of conduits with metal shell, so it is important to control the humidity.
Some use corrugated hose made of PVC, even in the wooden house, but it is risky because the material is flammable.Another option - a box of plastic, flame retardant (some attribute this method to open other - to the hidden wiring), but it is also not in compliance with the EMP and threatens to fire.
flexible metal hoses with asbestos gasket - medium variant, a stretch allowed by the houses made of flammable materials.Although in the good metal sleeves that do not support combustion, and boxes from corrugated PVC may be used in such a structure only if they are completely surrounded by a layer of plaster or other non-combustible material.
- For a house built of wood - combustible material - suitable only copper wiring.
- Wire is selected according to the load on the network.Mark the wire is chosen depending on the working voltage, which is calculated on the wire insulation.Some brands, suitable for flush wooden house:
- VVG and NYM - cables with copper conductors and PVC sheathed with similar specifications, with a single laying do not support combustion (self-extinguishing).For laying beam used NYMng-LS or VVGng.
- px and AR - insulation and sheath does not support combustion, etc.
IMPORTANT! desirable to create and save a plan hidden wiring.Do not install wiring chaotically in different directions.The cable should go horizontally or vertically, parallel to the wall.The route is chosen the shortest.Keeping several adjoining cables together is not permitted - between them should be the distance.
at the intersection provides additional insulation - such as a wire wrapped with insulating tape.SAE Chapter 2 contains the rules according to which the wiring is installed.
Unfortunately, many do not pay enough attention to the selection raspaechnyh boxes and other components, switches and sockets flush.These and other items should be selected specifically for the flush, because they are part of the system, and from them will depend on the supply of electricity to the house.
terminal boxes flush
flush in a wooden house, respectively, need only the metal terminal boxes, which are installed in accessible locations to serve.Terminal boxes for flush and are usually signed in the catalogs.For example, box raspaechnaya C / U-198 Steel.
socket flush with the ground
the mains outlet is needed for powerful home appliances, such as, for example, the water heater.Unlike conventional socket outlet flush with the ground is not two, but three terminals for connecting wires (phase, zero, ground).
connection sockets are best left to an electrician, and select the appropriate socket and can be himself.The mounting box outlet under the desired metal.The Council shall establish several outlets - at least double socket handy for sure.

A good manufacturer outlets flush with ground - «Schneider Electric», producing rosettes Study , such RS16-007k.This dvuhgnezdnaya outlet flush: the price in Moscow - 104 rubles, in Kiev - 21 UAH.Its specifications are:
- Rated voltage: 50Hz, 230V;
- Rated current: 16 A;
- type a clip of veins of a wire: screw;
- wire size: 2.5 mm sq .;
- color: cream.
IMPORTANT! When connecting a dual outlet phase and neutral must be connected to different conductive plates.Non-compliance with this rule will result in a short circuit.
one-button switch for flush
switch dvuhklavishny flush switch and one-button flush differ in the number of connected contacts.In the first three terminals, which are connected to the wire in the second - two.
to replace the conventional one-button switch is necessary to de-energize the apartment, check for power at the outlet, to dismantle the old switch in any sequence to connect the two wires to the two terminals of the new switch, fasten it to the wall, put on the lid, apply voltage and check if it works.
To install the switch in a new location for the flush mounting box is needed, as well as other elements of the system, it is desirable made of metal.Among breakers and similar devices for flush proven French Legrand.
For example, the switch 10A - IP44 - 250V Ivory VALENA (no. 774101) - Weatherproof switch-Key flush, price in Kyiv -102 hryvnia, in Moscow - 250 rubles.Specifications of the title.
Since most homeowners do not know the circuit, which is located on the wiring in their home, there is a question, as the detection of concealed wiring.
When damaged electrical wires, circuits and blown to find and eliminate breakage, replace the wire or just do not get him hammering nails or drilling holes need to know how to find the hidden wiring in the wall.In fact, how to determine the route flush will help Detector flush, he is the determinant flush, flush tester, scanner, sensor, locator.
searching apparatus may be different depending on what is needed to detect the depth at which lie the wires, etc. track detector can sense the electric field produced by wires, or work on the principle of the detector.
Index wiring may combine these two principles work.Choosing how to find hidden wiring in the wall of which tool to use, you need to take into account the range of its action.
example, Warning flush E121 (Woodpecker) will reveal the wiring at a depth of up to 7 cm, PDO 6 from «BOSCH» has an area of up to 6 cm deep water - up to 30 cm - handy radar POSP-1, etc..
The simplest scheme is to find hidden wiring consists of a transistor, the headset and a few batteries. route is determined by the fact, where the sound is loud as possible.
