How to detect hidden wiring in the wall

Household appliances useall and even those who are far from electricity. And when the house suddenly extinguishes the light, it begins to seem that life has stopped, because you are deprived of the usual conditions of existence. That's why in such situations each of us is not bad to know how to find an electric wire in the wall, especially since it does not have to resort to the services of an electrician for this. Even if the house does not have a special device for determining the wiring in the wall, there are methods to do this without any devices.

Most often, you have to resort to self-determination of wiring in the following cases:

• When installing a light switch or sockets to drill a wall or hammer a nail, there is no fear of getting an electric shock.
• In the event of a short circuit, which is dangerous, as it can cause a fire, and therefore it is necessary to quickly find out where the wiring has broken.
• During the repair or redevelopment of the apartment. When demolishing or erecting partitions, or when changing the location of the doorway. In this case, it is advisable to know how to find the wiring in the wall without a device, this will avoid damage to the electrical cable.
• When you check into a purchased apartment. To determine the location of existing electrical communications, if there are no documents from the plans for their deployment.

Device for locating wiring

The easiest similar device is an indicator screwdriver. Many have her houses, and if not, you can borrow from neighbors. Although the indicator is quite inexpensive, but it is very weak. It is not possible to determine the exact location of the wires even if they are successfully detected, the indicator will indicate a danger zone of 30 cm. It will not be possible to find a wire that is not live with the help of an indicator screwdriver.

Signaling E-121 called many people in the "woodpecker" is used by many electricians. It is so simple to handle that even an absolute dilettante can handle it. Nevertheless, this device can determine not only the location of the wires, but also where the impulse occurred. The depth of its action reaches up to 7 cm. This is quite enough to detect the gust of the veins behind the gypsum plasterboard skin. With regard to price and quality, the woodpecker can be called the best domestic device for searching for hidden wiring.

The MS signaling device manufactured in China has many modifications, but the most popular model is the MS-18.A feature of the Chinese detector of wiring is a high sensitivity to all metal, so it reacts equally to the conductor, and to nails, and even to the reinforcement in panels of panel houses. But you can find a difference in the strength of the signal. When choosing any model of the MS signaling device, it is worth considering that they will not react to the foil cable. Among electricians, these testers are not popular, and for the house this is an acceptable option, especially given their low price.

Professional wireline search devices

For sale you can find testers GVD-504A, BOSCH DMF 10 zoom, GVT-92, GVD-503, VP-440, produced by European manufacturers. They are usually used for detection, hidden under the finish and analysis of his condition by professional electricians. From Chinese analogues, they differ in build quality, compact and beautiful execution. The principle of their work is about the same, but the cost is quite high, especially if you buy for one-time use.

Water table for the prices of the devices under consideration

Ancient grandfather's ways of searching for wires in the wall

The high price of special devices is one of the reasons why home craftsmen are interested in how to find a wire in a wall without an appliance and often give preference to the hitherto proven methods of solving this problem. After all, in the old days, when there was a wiring in the wall, there were no appliances, finding electrical outlets under plaster and wallpaper by safe methods.

There are several ways to find hidden wiring in the wall without special technical means, and each of them can provide a different degree of accuracy.

1. Visual definition of a place of a lining of lines. This method is suitable for brick and concrete walls, covered with wallpaper, which are removed during the repair, this makes it easy to find the stroba, where the wires are usually laid. Since during the shtrobleniya the integrity of the surface is violated and even after embedding the place where it was conducted remains appreciable. If the wall is plastered or covered with putty under the wallpaper, it is not possible to visually detect the electric wire in the wall.

2. Using a radio or a receiver. This method of the master advises amateurs who are interested in how to determine where the wiring passes in the wall. And for this purpose, the most common, tuned to a medium-wave frequency receiver will work. Under the pleasant music, he must be led along the wall, watching for the appearance of crackles.

3. The microphone connected to a radio tape recorder can become an alternative to the receiver. Work with it follows, as with a radio receiver, the appearance of noise and cod will mean the detection of hidden wiring.

It should be remembered that using a radio or microphone you can determine the location of the wiring in the wall with an error of 15-20 cm. Therefore, when using these devices it is better to make a small indentation to avoid an electric shock and such a safety net will not be superfluous.

Let's try to do the logic of

If the wiring was done by a professional electrician, then all the conductors in the cavity of the enclosing structures were laid parallel to the ceiling or perpendicular to the floor, and all turns were made at right angles.

Based on this, it is possible to assume the following:

• From the socket or switch, the wire rises strictly upwards and then under the ceiling it turns to the side of the junction box, therefore, there is no need to drive a nail in this place.
• The line, as a rule, pulls back 10-15 cm from the ceiling and 10 cm from the skirting boards.
• It is possible to visualize the cable laying plan visually and to sketch it on paper visually according to the previously installed electro points.

It should be borne in mind that such a visual representation can not be called safe. The layout of the cable should be checked at least with the help of radio, but preferably with special devices.

Causes of wiring failure

An open in wiring may occur at any time, most often this happens when the electricians are under voltage. The cause of cable damage can be a poor-quality product, improperly made wiring and much more. In the place where there is damage, the wire is constantly heated and when the voltage rises, it may break. In addition, cable rupture can occur due to external mechanical impact on it, when driving nails or drilling holes. To the breakage of the cable leads and overload of the network.

Than to find a wire break in a wall

If earlier devices allowed only to find out wires or metal subjects modern electronic devices help in definition of a breakage of the latent conducting. For example, a non-contact indicator of concealed wiring can be used to locate the place of the phase conductor break. The indicator should be moved along the current-carrying vein, and in the place of its break it will signal. Normally, when you detects a wire break, the audio signal stops.

If you have an idea how to find out where the wiring is located in the wall, you can choose the appropriate search option based on your capabilities.
