Safety is the most important thing, which is why in some cases it is necessary to replace the electrical installation in a home or a public building. Many people wonder when the electrical installation should be replaced, but also when it is enough to repair the electrical installation or modernize it. What technical standards are necessary in the assembly of the network?

When does an electrical installation need to be modernized and when should it be replaced?
The electrical installation can operate without failure and for a very long time. It is generally accepted that after 20 years, the electrical installation needs to be modernized or replaced. Wires, even the highest quality ones, need to be checked. Can you recognize that the old installation needs to be replaced? There are symptoms that indicate that replacement is necessary, especially when there are frequent and unjustified blowing of fuses.
In addition, the installation should be replaced if it is over 20 years old. Of course, you should first check whether modernization and replacement of cables is not enough. If overvoltages continue to be very frequent, you will not avoid the need to replace the electrical installation. A faulty electrical installation is a great danger, as it significantly increases the risk of fire, but can also damage devices, such as a refrigerator or washing machine.
In addition, energy consumption also increases, which of course causes a significant increase in costs. The expansion of the electrical installation is also associated with the need to modernize it. Cables and wires play a key role, but also electrical equipment , such as a surge arrester for systems such as type 1+2.
How can you tell that an old electrical installation needs to be replaced?
Appropriate equipment, good cables, but also effectively functioning electrical engineering affect the level of safety and work efficiency. It is enough to mention disconnectors or fuse bases. Another important role is played by the surface-mounted switchboard. It is not always necessary to replace the entire installation. In many cases, modernization is enough.
So when does an installation need to be modernized, and when is it necessary to completely replace it? It is generally believed that the installation should be replaced when it is over 20 years old. Of course, in many cases, there is no need to replace it. All you need to do is apply a properly selected modernization system, which involves making repairs or replacing some worn-out elements.
However, if the installation is over 25 years old, it is highly probable that it will be necessary to replace it, as it will no longer meet restrictive quality standards or energy efficiency. When buying a flat or house on the secondary market, it is worth thoroughly checking the installation, lighting system and operation of the switchboard. The use of differential circuit breakers is also necessary, as they serve to directly protect devices, but also limit the potential effects of damage that may be caused by fire. Modular equipment such as surge arresters really has a significant impact on the safety of property.
Approximate costs of replacing electrical installations
By using appropriate safeguards and power supply or high-quality cables and wires in the walls, you can enjoy efficient and safe operation of the entire electrical installation. However, in many cases it is necessary to replace it, if only to ensure your safety and protect your property.
Here the question arises - how much does it cost to replace the electrical installation? Basically, it all depends on the size and selection of appropriate cables. It is believed that the costs oscillate around PLN 3,000 to even PLN 10,000, although of course the area of the house or apartment also has an impact. As you can guess, the smaller the apartment, the lower the costs will be.
In the case of apartments up to 50 m2, the cost will be around PLN 3,000, while in the case of a property with an area of 100 m2, the cost will be from PLN 8,000 to PLN 10,000. If your house is even larger and, for example, has about 150 m2, the replacement of the installation will cost PLN 13,000-15,000. The average price therefore oscillates around PLN 100/m2. In addition, you have to count about PLN 60 for an electrical point. Therefore, if the installation is over 20 years old, it should undergo a thorough modernization or replacement.
