Probably every man arose the need to make a hole in the wall to fix it in a nail or dowel. Seemingly elementary task, but in fact it is not so simple, as in the selected place of the wall can pass electrical wiring.
If you violate the integrity of a drill or a nail, you can get an electric shock, damage the whole electrical wiring, as well as the devices connected to it. Try to figure out how to better define the most hidden electrical wiring in the wall.
The most popular ways of finding the wiring in the wall
Among all the actual and effective ways of finding the wiring in the wall is necessary to highlight the following:
- Using the radio;
- A careful visual inspection;
- With the help of an ordinary screwdriver indicator;
- Special devices;
- Applying the hearing aid;
Let us consider each method in more detail
1. use the radio
For some people, this method may seem strange, but it really works and helps you find the wiring in the wall. To do this, take your receiver to configure its waveband strictly on 100 kHz, leaning against his as close to the wall (do not scratch the wall), extend the antenna and hold it with the tip of the desired section of the wall.
The only condition under which this method of work is the presence of voltage at the required wiring, as well as the silence in the room. As we approach the antenna to the wire, the receiver will emit a crackling than clearer and louder the sound, the closer to the antenna wiring. Delicate precision, this method certainly will not, but the plus / minus 5 cm will be enough to not drive the drill into the wire.
2. visual inspection
The most primitive, but no less effective way. Particularly relevant if you plan to change the wallpaper. After removal of the surfacing material and the filler layer becomes noticeable plaster layer used for glossing cutting grooves in which wiring is routed.
And if we define shtrobuna eye does not work, then you should hold a hand on the wall, so you are sure to feel the material and structural differences in this place and is under Stroebe electrical wiring.
3. indicator screwdriver
This power tool is in almost every home. Though the efficiency of detection of electrical wiring and poor by using this method, but it's better than nothing.
So, in order to determine the wiring in the wall using the indicator wiring, it is necessary to take the fingers of her sting, and the other end of the tool to drive on the wall in the desired area.
If at the end of a screwdriver indicator lights, it will indicate the presence of wires. At the time of using this method, the wiring must be energized. But with interest to rely on this method is not recommended, as it has a large error.
4. Hearing aid
For someone this method may sound ridiculous, but it is not, the hearing aid is able to determine the electrical wiring in the wall.
For this ideal standard hearing aid model AC-1. All feature of it is that it contains a function call, through which people with hearing loss can without any problems to chat on the phone.
To determine the cable in the wall, hearing aids translate it in this mode, we bring it to the desired area and We drive the device in different directions, as in the earpiece will be a distinctive sound, so at this point there is a wiring voltage.
5. Special devices
For the most accurate determination of the wiring in the wall, you can use special devices electromagnetic or electromechanical type, they will ensure maximum accuracy. Just for this purpose can be used a metal detector.
