A properly executed electrical installation is the basis for its safety for users, animals and property, as well as energy efficiency, functionality and long-term reliability. Knowledge and experience are needed to design and install electrical installations, which is why only specialists with appropriate qualifications should handle this task. Learn the three most common mistakes and good practices when running power cables and performing electrical installations.

Too few electrical points
Too few general purpose plug sockets in rooms is one of the most common mistakes in electrical installations. Investors are not always able to precisely determine their energy needs at the stage of designing an electrical installation. Therefore, a good specialist plays a significant role in the system planning process, who can identify the investor's needs (current and future) and advise him where in individual rooms it is worth placing electrical points.
Often, at the time of renovation work, the investor does not yet know what electrical equipment he will use and where exactly it will be located. However, it is definitely better to provide more electrical wires than too few.
Making additional sockets and making other changes to electrical installations after the interior has been finished usually involves interference with the walls, and consequently - time-consuming and troublesome renovation work. Alternatively, there is the use of extension cords.
A common mistake is to prepare too few lighting points, which results in the room being under-lit and the need to use additional lights, so electricity bills increase unnecessarily. Light points should be arranged in such a way as to evenly distribute light throughout the interior.
Inappropriate diameter of electrical cables and wires
Electrical cables that are not adapted to the loads occurring in the network are one of the so-called critical errors. Cables and wires that are too thin can overheat and, as a result, become damaged. Such defects pose a serious threat to the safety of the electrical installation and its users.
Therefore, when choosing installation cables, it is mandatory to take into account the technical requirements and the maximum load of the circuit. In addition, the cables must fit freely in protective structures, such as pipes and installation strips, so when choosing, you need to check the diameter and size. The method of attachment should be solid and safe - it cannot cause damage to the insulation of the cables.
The use of fuses with excessive load capacity
Protection devices used in electrical circuits, such as differential switches and electrical fuses, should be precisely adapted to the network parameters and the intended load. Fuses, or overcurrent switches or colloquially "plugs", protect the electrical installation and receivers from the effects of excessive electrical energy.
If an overload or short circuit is detected, they immediately interrupt the flow of current, which minimizes the risk of damage to the installation and electrical devices connected to it. A common mistake in the selection of protection is the use of fuses that are too large (with excessive rated voltage). They do not provide adequate protection against overloads, which in extreme situations can even cause a fire. As you can see, errors in the selection of fuses can have serious consequences for the safety of the entire installation and its users. Therefore, work on the electrical switchboard should only be carried out by authorized electricians.
