The best cables and wires for construction and repair for electrical wiring for 2020

When construction or renovation takes place, special attention is paid to the choice of wiring. There are dozens of different cable and wire options on the market today. Some are able to withstand overloads, while the other is a more budget option and suitable for "inactive" use. Due to such a variety of choices, even an experienced user is lost. It is important to understand that it is necessary to choose the best options for the house, since the safety of operation depends on this. Therefore, the editors of the site "bestx.htgetrid.com/en/" have prepared for you a rating of the best cables and wires for electrical wiring, which are suitable for construction and repair.

Kinds

Even if a person will carry out surface mounting or minor repairs, the first thing he needs to check is the condition of the electrical wiring so that everything is fine in all places. This requires:

• See the strength and quality of the connection in junction box... This is the first thing to pay attention to.
• The second is to tighten all the sockets, since if a long time has passed, then the probability of their loosening is high, it is also important to check the fastening of the screws so that they provide a snug fit.
• Visually inspect the condition of the electrical element for an object or the possibility of short circuit. If such a problem is found, then it must be quickly fixed.

Recently, a person began to consume three times more electrical energy. Progress does not stand still and now almost every house has a pair of TVs, a refrigerator, a separate freezer, a computer, an electric oven, etc. In addition, during the winter, the consumption rate increases even more, as the oil coolers are switched on.

The problem with conductive products is common and often causes fires. Therefore, it is necessary to pay special attention to it and try to make a timely replacement. When buying a wire, it is important to look at its quality; it should at least visually seem strong and reliable. If you buy good items once, then you can forget about replacing them for more than 40 years.

However, there is one caveat, if a person does not have sufficient knowledge and experience, then it is not recommended to start installation work on their own. It is better to take the time and find a suitable electrician who has wide experience and experience, and will also be able to advise on a number of important issues. Then you can start looking for a good option and there are a number of nuances that are important to consider when buying:

• As soon as it is noticed that the first letter "A" on the product, it means only one thing: the conductive part is made of aluminum. If the letter is different, the manufacturer indicates what material the surface of the electrical product is made of. So there are several options: "V", "P", "R" and "K", each indicates a specific material. The first three letters are vinyl, polyethylene (PE), rubber. Symbol "K" - the wire is a control one.
• The second mark in the marking indicates to the buyer about the insulation of the conductive part. The designation is put in exactly the same letters as in the previous version, so it's easy to remember.
• Separate symbols are often used to designate a structure. There are two letters - "ШВ", which indicate that the wire is completely insulated and protected from external influences. In contrast, the “E” sign means the cable is shielded. In addition, models are sold where the letters "G" and "P" are present. The first indicates flexibility and the second indicates the flatness of the product.
• In addition to the markings described above, the stores sell goods with a different designation. For example, you can often find the “NG” mark, which indicates that the cable is made of non-combustible material, so when burning it will only melt, which reduces the risk of fire spread. In contrast, the “LS” symbols mean that no toxic smoke will be emitted in the event of a fire and the product will not melt.
• In addition, there are various numbers on the cables that indicate the number of cores and their cross section. At some points it is necessary to pay special attention to this. This is how models are sold that are marked 3x2.5, which indicates: the wire is three-core, and the cross-section of each individual element is 2.5 mm².

The purpose of a product is indicated by its color. All manufacturers try to follow certain standards to make it easier to navigate during installation. When a wire has a brown, white or red tint, this means only one thing: the cable is a phase. Two colors are used to indicate grounding: green and yellow-green. Zero is blue.

Memorizing so many symbols can be difficult for the average user, but it is not necessary to study them carefully. Such knowledge will be useful only to a novice electrician, for him it makes sense. An ordinary user just needs to write out the necessary options and go shopping in search of a suitable one. In addition, if a person doubts his decision, then he can consult with a specialist in the store, who will show more acceptable options.

What to look for

Any repair of electrical wiring, no matter at home, in an administrative complex or an enterprise, begins with the choice of wire. It is important for the repairman to decide what is suitable for a particular place: a cable or a standard element. Although the difference between them is not so significant, it is still there. It is important to buy such products from trusted and well-known sellers, since they position their goods highly, therefore, they make elements from high-quality materials.

Cable, cord or wire?

As you know from school days, cable, cord and wire have different definitions. So if you trust the textbook, it turns out that the cable is several separate cores that are insulated from each other, but located inside one shell. An excellent example - VVG product consists of a copper element, which is in a PVC sheath and with the same insulation. This option has both one and four conductors, which can be of any cross-section, it all depends on the situation where it needs to be used.

The wire can also have several cores, which are insulated in a special sheath from each other, and then connected in one piece. In this case, the difference between such elements is minimal. In addition, there are representatives, for example PPV, (this is a flat model, the insulation of which is made of polyvinyl chloride), with a cross section of up to 4 mm², this allows them to be equated with some standard cables.

The cord, although it has the same design, is still different from the previous ones. Because it is made of flexible conductors, which are covered with simple insulation, while the protective sheath is also made of PVC. A good example, in this case, is PVA, this option is a copper wire that has twisted cores, the maximum cross section is 2.5 mm².

Nuances of choice

A separate book can be devoted to the selection of these products, since there are dozens of nuances and hundreds of different brands that are difficult to remember even for an experienced electrician. There are also hundreds of different moments during the installation of one or another option. To be convinced of this, it is enough to enter in the search line: "Correct installation of electrical wiring", a million results returned will show that you cannot find a definite opinion on the installation method.

But still, if a person decides to carry out an independent installation, then it is important to know at least the basic nuances. For example, laying in a house or apartment should be carried out with a product that has an increased cross-section. It is recommended to use the flexible model only in cases where portable devices are used, or weak systems where the maximum voltage is up to 24 V, that is, in cars. For home wiring, this material is prohibited. Better to use a good, durable cable and leave the wires for other repairs.

It is also important to understand that the best material in the home is copper cable. Using this element, a person will provide himself with reliability, which will reduce the risk of fire. Copper elements are often found when laying electricity in a wooden house, as they will protect it from various accidents and guarantee trouble-free operation for the entire period of operation.

Therefore, it is important to consider the material from which the conductive element is made.

• The cheapest is aluminum, it does not have a high current conductivity, and also quickly deteriorates and is rubbed in places of inflection, which can lead to negative consequences. Also, the negative side of such a product is oxidation. He is highly susceptible to this process and there is nothing good in this, because the conductivity due to this will become worse every month. If a person wants to save money, then this is a great way not to do this, it is better to buy a quality product.

• Copper products are completely different from the previous example. They are not susceptible to oxidation, although there is a chance, but it is not as great as with aluminum options. In addition, such cables are distinguished by good current transmission and are best adapted for use in private buildings, where durability and reliability play an important role. Their strength indicators are high, the chance of breakage at bending points is minimal.

It is important to understand that the price for such wires is much higher than that of the previous version. However, this cost often pays off. Since a person can be sure that for the next 10-15 years he does not even need to check him.

The last and main nuance when installing a cable in an apartment is that the product must be flexible. Most often, city wiring is distinguished by a large number of various connections and branches. Therefore, it is necessary to buy only durable models that will not break down in a dozen years and will last a maximum period.

What is important to know about the cross section

Cable brand and quality of materials are only the first point in choosing a quality product. Second, but no less important, is the section. Thanks to him, the product will withstand extreme loads or, conversely, due to the small section, the device will become unusable. Hundreds of options are sold on the building materials market, in one the value is 0.5 mm², in the other it reaches 16 and more mm²... If a person needs this product for lighting, then the best option is a three-core version with an area of ​​up to 1.5 mm², when it comes to connecting the outlet, here the indicator is different and is equal to 3x2.5 mm².

To determine the maximum accuracy of the section, it is necessary to carry out special calculations. How to make them is indicated in many video tutorials and hundreds of articles have been written. Therefore, a person should not have problems with this. If there is no time for calculations or the owner is not confident in his own abilities, then it is best to trust an expert who will quickly show the correct option and will not forget to take into account many seemingly insignificant details.

In addition, it is necessary to take into account the material from which the structure is made. If a person decides to use aluminum, then the entire result obtained must be multiplied by 1.5. Because it is at this figure that copper bypasses this element. For this reason, if a person is going to buy a copper wire, then he must understand that its thickness will be many times greater.

The choice may be influenced by the method of hiding, so some will prefer to hide the wiring under the plaster, while others will leave them on the surface. If the owner prefers the first option, then it is important to choose products with a large section in order to exclude the possibility of overheating and vice versa. In addition, it is not recommended to buy wires or cables end-to-end, it is better to leave a small margin of section, it will definitely come in handy, for example, when the owner buys new household appliances.
