Wiring can last a maximum of about 20 to 25 years. Then it comes into disrepair, and it needs to be changed. In modern conditions, replacement is required much earlier, because the wiring is charged with a very high load. In the Khrushchev houses and panel houses, this work is done in approximately the same way. In this article we will talk about how to replace the wiring in the apartment, give step by step instructions, as well as accompany all the photo and video materials.
Signs of destruction of electrical wiring
Electrical Appliances Wiring begins to break down over time. However, it can burn out much earlier. The reason for this today are various electrical appliances that require a lot of energy. Especially "voracious" unit - heater. Such devices can consume 7 times more energy than a TV.
If a computer, a refrigerator, a heater, and household appliances such as a microwave oven are simultaneously turned on in the network, then soon either electricity is cut off or irreversible wiring processes begin.
There are several signs that signal that it is time to start a major replacement:
The first three signs already indicate that it is no longer necessary to delay.
Electrical drawing of the house
Wiring is bought after the length of the route along which the cable will be laid out. It is necessary to make allowances for this length, so that the wires are exactly enough.
It is also necessary to take some consumables. For example, you need a rag tape.
Which cable to choose
The wiring should be replaced as follows , so as not to happen failures and overvoltage. For this, it is necessary that there is enough power for each device.
Required electrical equipment
Power depends on the cable cross section. To make the right choice, you need to make a small count.
If the number that came out as a result is within 12 - 15, then there will be enough wiring with a section of 1.5 mm2. This is the most common indicator. However, sometimes the result is higher.
Connecting the second line
If the result is higher than the specified interval, then the master has two way out.
The second option is preferable because a thicker cable makes the system unreliable. The probability of failures is great.
Connecting the wires to the shield
Now that everything is ready, it remains to understand how to replace the wiring.
This is the end of the work itself. Only decorative surface finish remains. If we are talking about a wooden house, the internal cable installation is almost impossible here. That is, theoretically it can be done with the help of professionals. But on their own for such a work is better not to take. In wooden structures, cables are carried out externally using various hoses.
