There are often cases when it becomes necessary to install external electrical wiring in administrative and residential premises. Such a need arises when new electrical appliances are installed in the room or a section of wiring in the wall becomes unusable.

Changing walls is not always possible or leads to lengthy repairs, and in industrial premises there is no need to hide wires in the wall. A good solution for tidy and safe installation of wiring on top of walls is a plastic box.

Advantages

Plastic cable duct, as the plastic cable box is called in another way, is a rather successful design made of polyvinyl chloride. So, in comparison with other devices or types of laying, a plastic box has the following advantages:

• aesthetic appearance;
• variety of colors, which allows you to choose a box for the interior of the apartment;
• the strength of the product, which is shock-resistant and can withstand the weight of a heavy cable;
• fire safety in accordance with current regulations;
• resistance to temperature changes;
• ease of installation and maintenance.

Due to these properties, plastic conduits for wires are becoming more and more popular when installing outdoor electrical wiring.

In addition, the most famous manufacturers of plastic cable channels, such as "Elekor" and "Legrand", complete their products with various fittings, which helps to significantly cultivate and refine the design of the plastic box for wires. Features such as end caps, tees, and internal and external corners eliminate pipe holes and dramatically speed up installation. The production of PVC cable channels is carried out using modern technologies and is constantly being improved.

Selection and calculation of material

In order to make a normal and reliable installation of a PVC box, it is necessary to determine some details and conditions for the upcoming work.

When planning the installation of a PVC cable channel, the following factors are taken into account:

1. Thickness of electrical wiring and other cables to be installed.
2. Dimensions of the box for individual installation areas.
3. Possibility to install additional wires and cables in the future.
4. The material of the surface on which the cable duct will be installed.
5. The possibility of using PVC skirting boards with a cable channel for placing wires in it, when wiring inside rooms.

A plastic cable box is available for sale, measuring 2 m in length and in a wide variety of widths and heights. The shape of plastic cable ducts can be very diverse.

They can be manufactured in the following form:

• rectangle;
• square;
• triangle;
• semicircle.

Based on the shape and size, the plastic box can be:

1. Ceiling type. This product has the smallest size, as it contains thin wires intended for chandeliers or spotlights. It is used, as a rule, when laying a new line along the floor slab. In addition, when installing a suspended ceiling made of PVC panels, the box is used for distributing electricity to fans and lamps. A good solution is to use a perforated plastic box for placing wires on the ceiling when installing PVC film stretch ceilings. The ability to quickly make a side hole in the walls of the box when it is fixed to the surface saves a lot of time and effort.
2. Wall type. The wall version serves to bring wires to the sockets and to the ceiling. Outlets require fairly thick wires to withstand powerful electrical appliances. Based on this, an appropriate box size is selected for them. Conducting the wire to the ceiling is best done through a cable duct installed in the corner. There it will not be conspicuous, and tastefully selected in color - it can harmoniously complement the interior of the room.
3. Sexual type. The floor plastic cable channel quite successfully replaces the usual wooden or plastic floor plinth. Size does not matter as much here as it does for wall and ceiling products. The large size of the floor box can be regarded rather as a plus. In addition to the fact that it closes the gap between the wall and the floor, the presence of a spare space under the lid can be useful for the subsequent laying of satellite TV, alarm or Internet cables in it.

On a note: White plastic products are presented in the largest assortment. It is easy to give them the desired color by painting or pasting with a film.

Installation of a plastic cable channel

Before installing the cable channel, it is necessary to determine the size, shape, number and color of products that will be used during operation.

Drafting a project

Design consists in drawing up a diagram of the location of electrical wiring, television and optical cables in the room. Based on the thickness of one wire or their bundle, the type and size of the box is selected. All these nuances are noted in detail on the diagram.

• connecting strips;
• inner and outer corners;
• PVC mounting boxes for wiring;
• plugs;
• tees;
• fastening material.

When the required amount of different types of boxes is calculated, you can find out the amount of fasteners. Usually, self-tapping screws and plastic dowels are used for fastening. The line is fixed to the surface every 30 cm. Its total footage should be multiplied by 3.3 to get the number of screws.

Purchase of material

Before going to the store for shopping, it is recommended that you familiarize yourself with the assortment of goods and their prices on the websites of construction stores. This will save not only money, but also time.

If you have to make purchases in several places, then it is better to hire a cargo taxi. So the goods will be safe and under control. It is not recommended to carry PVC products in the trunk of a passenger car - they may break or be scratched.

At the time of purchase, it is necessary to carefully inspect both the panels and the components.

Attention should be paid to the following:

1. No deformation. When storing parts on short shelves or stacked unevenly, they become bent and take on an irregular geometric shape that cannot be changed.
2. The presence of mechanical damage. Cracks in products can lead to breakage of individual fragments during installation.
3. Coating condition. It should not be stained, frayed or sunburned. Such defects will greatly spoil the overall appearance of the structure.

Material with strong walls should be purchased. You can test the reliability of the lock connection on one of the fragments of the box during inspection - its lid should be removed gently, with little effort and, easily, without hitting it, closed. The absence of a sharp click indicates the quality of the product.

Instruments

The very process of arranging the highway, after this process has been designed and prepared, is a fairly simple event. All that remains is to prepare the instrument.

For work you will need:

• puncher;
• screwdriver;
• hacksaw for metal;
• miter box;
• hammer;
• sharp knife;
• pliers;
• pencil or marker.

The set is simple and is in every home. After collecting it and checking the serviceability, you can get to work.

Installing the cable channel

Having a project, material and the necessary set of tools in hand, it is easy and fun to work.

The stages of this work are as follows:

1. Carrying out markings on the surface. The location of the highway is applied, marks are made for drilling.
2. Holes are made in the surface, plastic dowels are inserted into them.
3. The box body is screwed on.
4. Wires and cables are being laid. They can be stacked one at a time or bundled using a plastic tie.
5. Wiring is in progress.
6. Sockets, corners, plugs and housing cover are installed.

The work is done.
