What materials are needed for wiring

Electric power input

In a new building, especially when it comes to a private house, you often need to take care of the input of electricity. There are two options for how to do this:

1. Entering from the overhead line by air.
2. Cable entry underground.

What materials should be prepared for each of the situations? Branch off-line SIP wire. In addition to the wire itself, you will need more piercing cable clamps or so-called nuts. With their help, wires are connected to the line without removing voltage.

For underground input you need armored cable VBBSHV or ordinary type cable VVG, but then all unarmored products underground must be laid in the PND-corrugated pipe. It will protect against damage in case of soil displacement and the impact of loads during operation.

Further wiring is to electrical panel assembly. A modern entry shield consists of:

• Circuit breakers;
• RCD;
• Voltage relay and other automation.

Sometimes the first two points replace difavtomatami. All modern wiring products are installed on Din rail. According to the choice of manufacturers, the leading positions are held by companies:

• Schneider electric;
• ABB;
• Legrand.

IEK products are a more affordable option. The quality of the company's materials is acceptable, but many electricians often come across fakes.

It is also worth noting that most experts agree that KEAZ brand products can be distinguished from domestic manufacturers.

Wiring

Consider what you need for electrical work in the house and apartment. The materials for the installation of electrical wiring are primarily cable products. In most cases, they do not pay due attention to such an important issue and trust contractors. However, the quality of the cable determines the durability of the wiring.

To lay the wiring in the apartment you need to use a type VVG cable. It consists of a flexible monolithic core of copper, a vinyl sheath of veins and a common sheath of vinyl.

Now on the market its modifications are presented:

• VVGng - the prefix -ng, says that the cable is made of materials that do not spread combustion.
• VVGNG-LS - the prefix -ls, says that it not only does not spread combustion, but also emits a small amount of smoke.

Also for wiring, you can use NYM cable, it consists of flexible multi-wire copper cores coated with a PVC sheath and the general sheath is also made of PVC. In other characteristics, it is similar to VVGNG-LS.

Wires PVA and brand cords Ball screw not intended for use in permanent wiring. Their purpose is extension cords and use as a power cord for mobile electrical appliances and household appliances.

For wire connections need terminal blocks Wago, terminal blocks of a standard sample or special sleeves. You can also connect the wires by welding, but for this you will need a special welding machine and consumables such as electrodes and flux.

Fasteners

The next conditional group of materials for electrical work is fasteners and protective materials. These include cable management tools, what do you need?

Wiring is hidden and open. Hidden wiring suggests wall chipping and cable laying in gates, followed by termination and cladding. TO open wiring refers to the laying of cables on the surface of walls and ceilings, including if subsequent finishing will be carried out with plasterboard structures or suspended ceilings.

Recently, there has been a tendency to lay cables in the corrugation, even with hidden wiring. This is not necessary, but laying in the corrugation takes less time if you have access to a gas gun for dowels.

The corrugation is mounted on the surface of the walls with clips or dowels. With a gas gun, you can significantly speed up the fastening of clips on the cable line, and the installation of the cable in the corrugation in the clips takes place in a matter of minutes.

In wooden houses, electrical work on laying and organizing hidden electrical wiring is generally prohibited. Therefore, it is laid in the corrugation or cable channel on the surface of walls and ceilings. Corrugation does not meet the aesthetic needs of most people, so the choice is stopped on the cable channel. Most often they are white, but other colors that are better suited to your needs can be found on sale.

However, if you still do not want to see electrical wiring in the cable channels in your interior, carry out electrical installation in ceiling and floor skirtings. Quite a lot of manufacturers produce such products with a sufficiently large compartment for wires. Then you minimize the visibility of electric lines on your walls. Moreover, such a laying method is allowed according to the PUE.

At the same time, you can make the visible parts of the line a twisted decorative cord on ceramic insulators.

So, for wiring in an apartment or in a private house not in wood, you need a list of materials:

1. VVG or NYM cable.
2. PVC corrugated pipe.
3. Clips or dowel clamps for corrugation.
4. Fasteners for clips and dowels (self-tapping screws with plastic dowels or dowels for the gun).
5. Disks for a chamfer or drill for a puncher, drill, crown.
6. Terminal blocks.

For laying wiring in a wooden house you need to purchase the following list of materials:

1. Cable NYM or VVGNG-LS / VVGNG.
2. Perhaps a decorative twisted braided cord with ceramic insulators.
3. Cable ducts or baseboards with a niche for wiring.
4. Fixture for channels and plinths (self-tapping screws or glue).
5. Terminal blocks.
6. Drills, crowns and more.

Wiring Accessories

After completing the electrical work on laying cables or in parallel with them, you need to install sockets and switches. Everything is simple here:

• For electrical installation in a wooden house and outdoor wiring, overhead sockets and switches with a non-combustible base (PUE) are needed.
• For electrical installation in apartments and houses with concrete, cinder blocks and other types of walls, internal sockets and switches are more often used.

In the domestic market, products from Legrand and Schneider Electric have earned special trust. Their budget lines are produced at domestic factories, and the range allows you to choose both cheap products and premium products.

Also for internal outlets and switches you need to purchase sock, and for connecting and branching lines, internal junction boxes. By the way, junction boxes are also needed for open wiring.

In conclusion, we recommend watching a video that clearly shows what is needed for electrical installation in an apartment and a house:

We have compiled generalized recommendations on how to choose materials for electrical work. Share in the comments what products you use when laying electrical wiring and for assembling switchboards and which manufacturers you trust the most!
