How to detect hidden wiring in the wall

household electrical appliances used by all, even those who are far from electricity.And when the house suddenly goes out the light begins to seem that life has stopped, as it denies the existence of customary conditions.That is why in these situations, each of us, a good idea to know how to find the power cord into the wall, the more so that this does not necessarily use the services of an electrician.Even if the house is not a special device to determine the wiring in the wall, there are methods to do this without any devices.

most often to self-determination of the wiring is necessary to resort to the following cases:

• When installing light switch or outlet to the wall, drill or hammer a nail without fear of electric shock.
• In the event of a short circuit, representing a risk, as it may cause a fire, and, therefore, it is necessary to quickly find where an open wiring occurred.
• During repair or redevelopment apartment.When the demolition or construction of walls, as well as changing the location of the doorway.In this case, it is desirable to know how to locate the wiring in the wall without the device, this will avoid damage to the electric cable.
• When you check in the apartment purchased.To determine the location of existing electrical communication, if there are no documents with plans for their placement.

The simplest such device is a screwdriver indicator.Many have it at home, and if not - you can borrow from the neighbors.While the indicator is quite inexpensive, but it is very weak.Determine the exact location of the wires, even when successful, they can not be detected, the indicator points to the danger zone of 30 cm. You can not display using a screwdriver to find the wire is not under strain.

signaler E-121 nicknamed by the people "Woodpecker" is used by many electricians.It is so easy to use that it will be able to handle even the absolute amateur.However, this device can determine not only the location of the wires, and where the impulse occurred.The depth of its action comes to 7 cm. This is sufficient for the detection of impulse conductor for gypsum sheathing.In terms of price and quality "woodpecker" can be called the best domestic appliance to search for hidden wiring.

At alarm the MS, manufactured in China, many modifications, but the most demanded model of MS-18.The peculiarity of the Chinese detector wiring is a high sensitivity to all metal, so it is equally responsive and conductive wire, and nails, and even for rebar in slabs of prefabricated houses.But prilovchilis can find the difference in signal strength.Choosing any model alarm the MS, it is worth considering that in the foil cable, they will not respond.Among these electrical testers do not enjoy popularity, and for the house is a perfectly acceptable option, especially in view of their low prices.

for sale can be found GVD-504A tester, BOSCH DMF 10 zoom, GVT-92, GVD-503, VP-440, manufactured by European manufacturers.They are usually used to detect hidden under trim and analysis of its state professional electricians.From Chinese counterparts, they differ in build quality, compact and beautiful execution.The principle of operation is about the same, but the cost is quite high, especially for single use purchase.

Vintage antiquated ways of finding the wires in the wall

high price of special devices - is one of the reasons why domestic craftsmen interested in how to find a wire in the wall without the deviceand often prefer the old-fashioned repeatedly tested in practice methods for solving this problem.Because in the old days, when detecting the wiring in the wall do without instruments, finding the power under the plaster and wallpaper safe methods.

such ways to find hidden wiring in the wall with no special hardware, there are several, and each of them can provide varying degrees of accuracy.

1. Visual determination of the routing space.This method is suitable for brick and concrete walls, wallpapered, which is removed for repair, it allows you to find Stroebe, which are usually laid wires easily.Since shtroblenie surface integrity breaks down and even after termination location where it was performed, it remains visible.If the wall is plastered or covered with putty under the wallpaper, then visually detect the electric wire in the wall is not possible.

2. With the help of radio or receiver.This method masters advise amateurs who are interested in how to determine where the wiring in the wall.And for this purpose it will fit most usual tuned to the medium-frequency receiver.Under pleasant music it should be led along the wall, watching the appearance of crackle.

3. The microphone is connected to the radio, could be an alternative to the receiver.Work should be with him as with a radio receiver, the occurrence of noise and cod would mean the detection of concealed wiring.

We must remember that with the help of radio or microphone, you can determine the wiring in the wall to find the error of 15-20 cm. Therefore, the use of better to make a small indentation of these devices in order to avoid electric shock and such a safety net is not superfluous.

try to do logic

If the wiring carried out by a qualified electrician, all conductors in the cavity walling them were laid parallel to the ceiling and perpendicular to the floor, and made all the turns at a right angle.

apartment Based on this, we can assume the following:

• from the outlet or switch wire rises straight up and on the ceiling rotates in the direction of the junction box, therefore, at this point not to drive in a nailworth.
• line is usually pulled departing 10-15 cm from the ceiling and 10 cm from the skirting boards.
• can be visualized by the previously set points Electrical cabling diagram and sketch it out on paper.

It should be borne in mind that secure such a visual representation can not be named.Scheme cabling must be checked at least by means of radio, but the best special devices.

Reasons for termination wiring

Interruption in the wiring may occur at any time, often it happens when Elektroprom ovodniki, are energized.The cause of damage to the cable can be of poor quality product, improper wiring, and more.In the place where there is damage, the wire is heated constantly and can end with an increase in voltage.In addition, the cable break may occur due to external mechanical impact on him, nailing or drilling holes.For cable breakage and causes network congestion.

How to find a broken wire in the wall

Earlier devices allow only detect metal objects or wires, the modern electronic devices help in identifying the buried wire breakage.For example, a contactless indicator flush can find a place of discontinuity of the phase conductor.The indicator must be moved along the conductor, and in its place he will signal failure.Typically, when determining the wiring continuity buzzer stops.

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