When it comes to replacing the electrical system in the house, many of us are intimidated by the cost of such an undertaking. Unfortunately, the replacement of an electrical installation is not a cheap service, but it is necessary in case of a severely damaged or outdated installation. Find out when it is necessary to replace the electrical installation and what is the cost?
Why is the wiring changing?
The main reason for replacing an electrical installation is safety. This applies both to the protection of home appliances and, above all, to the health and life of people. Incorrect installation can cause a fire, so it is worth knowing the most important information about the need to lay new cables.
When to change wiring?
There is no provision in the legislation that would specify exactly after how many years it is necessary to replace the electrical installation in residential buildings. There is only a record that homeowners are required to keep it in proper technical condition. However, the installation of new cables is necessary in a number of situations. More on that below:
Old electrical installation
An old electrical installation can be defined as a system that is more than 20-30 years old. The last two decades have brought new technical standards for the installation of networks. For example, in the past, mainly aluminum cables were laid, which are easily heated and damaged. Today, installers use copper wires, which are much more resistant to high temperatures. Therefore, it is worth considering installing new cables in the bathroom and in the kitchen, where the most overloaded equipment works.
In addition, with a large number of household appliances in the house, the old electrical installation may be inefficient. This is manifested in the fact that the simultaneous inclusion of several devices (for example, a dishwasher, an oven and a washing machine at the same time) causes too much load and the fuses “burn out” or knock out the machines.
Broken electrical installation
Very often, an old electrical installation needs to be replaced. This can be diagnosed with frequent short circuits and breakdowns. Perhaps it is already so damaged that new wires will be required. To do this, you must first check the installation with qualified electrician.
An electrician inspects the installation and determines if part or all of the installation needs to be replaced.Only part of the system may be replaced if this is sufficient to ensure correct operation. This is a cheaper and less invasive solution. Then the old wires remain, but the power is turned off from them.
House extension and electrical wiring replacement
If you are planning to expand your home, consider installing new wiring or at least updating the old one. Especially if the building has an older type of installation. Remember that retrofitting is not always cheaper than a new installation and is not always possible. This will be assessed by a specialist who will indicate the best course of action in a particular case. After that, the selected designer will prepare an extension or replacement project. To ensure that a new or upgraded installation is operational and resistant to sudden power surges.
The cost of replacing an electrical installation
IN cost of replacing an electrical installation includes not only the purchase of new wires, but also the installation of new lighting points, switching points and new equipment. So the final price will depend on the size of the house as well as the quality of the materials used. In addition, there is the price of labor, so the difference in valuation can be significant. The final cost of replacing the electrical installation or its modernization will be from several hundred to several thousand rubles.
