Eight golden rules for repairing apartment electrical wiring. Repairing electrical wiring in an apartment with your own hands Why electrical wiring burns out

1. How to detect the location of a broken power cord? To avoid cutting the wire different places, you need to do this: connect a working electrical appliance (iron, tile, etc.) through it, and then turn on the mid-wave radio. Now take the cord in your hands and move it from beginning to end. When you touch the break point, a cracking sound will be heard from the receiver.

2. Using a transistor receiver, you can find a hidden wiring route in the wall. To do this, you need to plug into the outlet some weak source of interference, for example, an electric razor with a disconnected noise filter. Set the receiver in the mid-wave range (but not to the station) and start moving it along the wall. When crossing the wiring route, the crackling sound from the speaker will intensify.

3. For hidden wiring, aluminum wire in vinyl chloride insulation is often used. It breaks easily. Broken off in hard to reach place the wire can be extended.

A piece of wire of slightly smaller diameter than the broken wire is wound tightly, turn to turn, with an extension cord also made of aluminum. Then the resulting spiral, like a nut, is screwed with force onto the end of the broken wire. The connection point is isolated.

4. It is not always possible to clean the electrical wire from the plastic insulation without damaging the wire. To prevent this from happening, first bend the wire and carefully press the tip of a knife onto the insulation. The insulation layer will rip apart before the blade touches the metal. After this, the insulation can be easily removed with pliers. You can remove the plastic insulation from the wire without damaging it using an aluminum clothespin. Two grooves are cut into its jaws, the tip of the wire is inserted into them, the clothespin is squeezed with your fingers and the wire is pulled out with force.

5. Varnish coating from the surface thin wire(with a diameter of 0.2 mm or less) remove the soldering iron: placing the wire on wooden stand, run a hot tip over it several times. Under the influence high temperature The varnish immediately comes off the surface of the wire.

6. If, when repairing electrical wiring, you did not have it at hand insulation tape, then polyethylene will help out. Wrap the wire with plastic film tape, melt it with the fire of a match and insulate the connection with the heated mixture.

7. An electric lamp in a chandelier, floor lamp or wall lamp. Unscrewing it and replacing it is a trifle. But don't rush to do it with your bare hands. The lamp base often ends up being screwed so tightly into the socket that when you try to unscrew the lamp, its cylinder breaks. In such cases, an unusable rubber ball, cut so that it can be placed on the lamp cylinder, will help protect you from possible injuries. If, when replacing a burnt-out electric lamp, it breaks, do not rush to use wire cutters or pliers. In many cases, the lamp base can be unscrewed using a bar of soap. In this case, of course, you need to take precautions: turn off the lights or remove the plugs.

8. Sometimes the power cord of an electrical appliance needs to be kept close to the power plug in order to turn on the device at any time. For this purpose, it is convenient to use a simple clothespin holder. The clothespin is attached with screws to the wall near the outlet and the power cord is inserted between the clamps.

9. Food sometimes freezes so tightly to the bottom of the refrigerator evaporator that it is difficult to tear it off. Just put it on the bottom of the evaporator plastic film, and the products will no longer freeze to it.

10. On particularly hot days, refrigerators sometimes fail to cope with their duties, and the temperature in the chamber is above zero. You can help the refrigerator by placing a small fan behind it so that a stream of air hits the condenser.

11. You can get rid of the rattling and noise of the motor of an old refrigerator in the following way. You need to take a rubber band, bandage or tube, wrap it around the compressor in one turn and secure both ends with tension to the side walls of the refrigerator. The vibration of the compressor will decrease, and the noise will also decrease.

12. Cracks on interior panel It is best to seal refrigerator doors with polystyrene glue. Thin cracks are rubbed with a finger dipped in glue. On large ones, one or two layers of fabric soaked in glue are applied, after which the patch is carefully smoothed and rubbed.

How to fix electrical wiring?

Before you repair the wiring, you should identify damaged areas and diagnose the causes of the problem. All electrical problems can be divided into 2 categories: broken wires and short circuits. The work does not take much time if we're talking about about damage to the cord of an electrical appliance. Everything becomes more difficult when a specialist has to look for damage to wiring installed in the wall. This work requires professional equipment.
  If electricity goes out in the apartment, the technician checks junction box. Finding the location of the wiring damage is done in a logical way: if the lights in the room go out, it means that the wire damage occurred in front of the room; if there is tension in the room, the trouble should be looked for in the area located after the room. In this way, the entire apartment or house is checked until a fault is detected. Next, the cause of the break is determined (broken wires, loose contacts, etc.) or short circuit(insulation damage, unreliable connection of circuit elements, etc.). To fix electrical wiring, the technician can replace some sections of the chain.

 Repair wiring It’s not that difficult if you know exactly where the damage occurred and for what reason. In some cases, special equipment is required to diagnose the problem and fix it. Contact 5 Masters if you need to repair wires or cables. We will take on any job - very simple or the most complex. Our technician will come to any address in the capital, as well as the nearest Moscow region, to repair the electrical wiring as quickly as possible. We look forward to your inquiries every day, including weekends and holidays.

This happens quite often. With great difficulty we hang the carpet on the wall, but we are not happy with the result for long: for some reason the lamp in the room stops burning. Or, to hang a shelf, but sparks fly out from under the drill, a crash is heard, and the apartment plunges into ominous darkness and silence.

The reason for the misfortunes is outrageously simple - we were unlucky, and we Hidden electrical wiring cable damaged. In the case of a carpet, most likely the phase or neutral conductor was broken. And when they were preparing the holes for the shelf, they damaged the insulation of both cores and caused a short circuit (the drill, of course, can be thrown away immediately).

To resolve the situation, the line damage must, of course, be found. In the case of a shelf, this will not be difficult - where they fought at the time of the short circuit, there is a damaged area.

It will be more difficult with the carpet, which we successfully hung after punching a dozen holes. Two questions arise. First: “Which wire is damaged - phase or neutral?” And the second: “In which of the holes did we damage the cable line?”

If, when installing a dowel and a self-tapping screw in a hole, we interrupted phase wire , then there is a danger of defeat electric shock. Self-tapping screw, metallic profile, metal elements decor and interior - all this can be energized if installation is unsuccessful. You can verify the absence/presence of danger using a working and reliable device. In addition, we must remember that there can be not one damage, but two or more. The identified danger should be eliminated by first disconnecting the voltage: unscrew the self-tapping screw, metal parts dismantle.

Next, we need to decide which part of our apartment electrical wiring has failed as a result of damage. It is extremely rare that after a line is damaged, the light in the entire apartment goes out; usually one lamp or one or more sockets simply stops working.

If, then the indicator can check the presence of a “phase” in it. There is a “phase” - damaged neutral wire Nick. There is no “phase” - we look for the place where it breaks using devices that respond to changes in the electromagnetic field, for example, indicator screwdriver with a phase detector.

You just have to remember that outsiders cable lines, passing parallel to the test subject, can cause interference and distort the instrument readings. Therefore, group ones that are not related to our tests must be disabled.

If the lamp refuses to work, the input cable of the box, the switch cable, or the lamp cable itself may be damaged. Usually, by the location of the box, you can understand which cable we are dealing with. Damage to the phase conductors of the luminaire wiring is detected when the switch is on.

In any case, the points where the phase conductors are broken are usually quite easy to find.

With a damaged neutral conductor the situation is a little more complicated. It will be necessary to make some preparatory work: disable circuit breaker affected group, unhook the damaged neutral wire from the bus and apply a “phase” to it. Further, the damage can be found in the same way as in the case of damage to the phase wire.

A similar method is used to detect damage to the lamp switch cable if it is located after the switch itself. Since they are phase, it will not be possible to find out anything under voltage in this situation. It will be necessary to turn off the circuit breaker and the switch, and then apply voltage to the phase conductor from the lamp side - then it will be possible to find the break point.

At searching for faults in neutral conductors It is often unknown which wire on the N bus in the distribution board belongs to the damaged line. Then you can disconnect the input neutral conductor from the common bus, open the nearest branch box of the affected group and, having determined the neutral wire, apply a phase to it from the load side. Then everything continues as before.

But finding the damage is only half the battle. As a matter of fact, you don’t have to do this at all, but immediately replace the damaged cable section. A lot depends on the situation. Let's say a damaged wire goes from a lamp, socket or switch. Then it makes sense to change the cable completely.

But if the group cable coming from is damaged, replacing the entire cable may not seem practical. After all, the cable can run along the walls of several rooms and have a large length. And in order to replace part of the cable, you will need to install at least one additional branch box, and this is already associated with. The groove will need to be cleared to free the ends of the cable running in the wall and to prepare the hole for the box.

Clearing the groove- a responsible matter that requires caution. This is best done with a hammer and chisel, breaking off small pieces of plaster and being careful not to damage the cable. Of course, the voltage must first be turned off. You should refrain from using power tools, because all it takes is one careless movement and the damage will become even more serious.

It is necessary to clear the groove approximately 15 centimeters from the damage in both directions. Then you need to move the ends to the side and punch a hole for the branch box. We install the box using alabaster, and insert the cable from the groove into it. If the damage has not significantly shortened the length of the cores, or there is some reserve, then you can insert the cable into the box on both sides and connect the cores with standard terminal blocks. That is, it is possible to do without replacing the cable by simply connecting the old cores by color. This is especially useful if the cable is damaged in only one place.

The new part of the cabling, if available, is usually installed in. The most important thing here is not to overdo it and damage other cables while drilling holes for the dowels. Well, don’t forget to disconnect and plug the old and no longer needed part of the wiring.

We close the newly mounted branch box with a lid, plaster it, level the wall and glue the wallpaper - the work is completed, you can apply voltage.

Conclusion.

Although it is absolutely clear that damage to a hidden wiring cable is not a “tragedy”, when performing repair work However, it is better to first use devices to search for live conductors so as not to create unnecessary problems. Better yet, have detailed plan location of electrical wiring lines with an exact indication of the height of the cables. Still, repairing damage is quite a troublesome and dirty task. Yes and interior decoration Such renovations will not benefit the premises in any way.
