What is a box for electrical wiring

An electrical product called an electrical wiring box, or cable channel, is used to install cables and wires on the walls, the floor, or the ceiling. Power or low-current wires are routed inside the cable channel, which has a cross-section that resembles a closed profile and can be either rectangular or triangular in shape. In contrast to corrugation, which serves comparable purposes, the wiring box is foldable and is made up of the channel’s inner cavity and lid. When internal wiring is deemed inappropriate, the electrical box’s primary application is in network provisioning organization.

When installing concealed wiring is not suitable, power or low-current cables are arranged in boxes.

In order to guarantee a secure and well-organized electrical system in any home, electrical wiring boxes are necessary. By containing sparks or heat that could result from defective wiring, they not only shield electrical connections from outside damage but also aid in reducing the risk of a fire. These boxes come in a variety of forms, including metal and plastic, and each is appropriate for a particular wiring requirement and setting. In order to guarantee both safety and functionality, homeowners or installers should be aware of the various building codes and standards that must be followed during the installation process, even though it is a simple one. Comprehending the benefits and appropriate techniques for installing wiring boxes can greatly improve the effectiveness and security of a house’s electrical infrastructure.

Advantages of the electrical box

The following are the primary benefits of having wiring inside the cable duct:

  • ease of installation work;
  • mobility;
  • availability of communications for modernization or repair;
  • the possibility of installation in well finished rooms. The electrical network, packed in a box, has quite acceptable aesthetic appearance;
  • scalability. If the size of the box is correctly calculated, there is always an opportunity to lay additional cables and wires in case of need in the future.

The technology of using wiring boxes has become widely used in both the industrial and residential sectors because of how flexible the installation process is.

If there are any issues, it is simple to fix them by opening a suspicious area of the cable network.

Plastic boxes, among other things, are very inexpensive to produce and greatly lower the possibility of mechanical damage to the wiring.

They consistently conceal power lines from anyone who might be at risk from electric current exposure.

Installation of the cable duct

The mounting box industry manufactures a variety of styles and compositions from various materials. Most of it is composed of metal and plastic. However, electrical cardboard, fiberglass, and even wood are occasionally used to make boxes.

There are various kinds of cable channels, depending on their size and intended use. However, the box’s ability to accommodate power lines in a closed space and its closedness are thought to be its general design principles. In contrast to trays, which support the wiring during installation, cable channels have covers that are simple to take off and replace. Cover attachment options include glue, clamps, screws, bolts, and snaps.

It is possible to create wiring in the cable channel for both the walls and the floor. To lay a single or two wires, utilize cable channels with narrow cross sections. It is considerably simpler to install multiple wires in a cable channel that has a partition. Plastic boxes with varying cross-sections can be employed in a structured cabling network, contingent upon the wire thickness. You can use cable channels, stylized under the tree, to make the cable network blend in with the room’s overall design. You can determine the cable channel’s wire color if needed.

Choosing a box for electrical wiring and calculating its dimensions

Let’s examine the primary installation box types in the context of their intended use and purpose in order to select the best kind and size of cable duct.

Metal boxes

Steel rolls are used as the production material for these boxes. Galvanized sheets are most frequently used, and they have a longer service life than regular metal. There are all-metal and perforated boxes, depending on the use. Perforated products have the benefit of being lighter, and all-metal boxes satisfy stricter safety regulations. Additionally, metal hermetic sleeves are available and are utilized for cable routing in particularly risky locations, such as near gas, water, and other appliances.

Metal boxes are utilized in locations where there is a higher chance of fire or where there may be contact with caustic chemicals.

Wooden cable ducts

Wooden boxes are not made in the modern industry. Depending on the circumstances, masters may install the cable channel independently from wooden components in certain unique situations. The idea of the "pencil case" is applied. The ability to quickly access the wiring concealed inside the box is the primary requirement for it.

Plastic installation boxes

Right now, plastic boxes are the most in demand. Professional electricians and builders alike have come to greatly appreciate plastic cable channels for their low cost, high dependability, appearance, and ease of use.

Producers create a large selection of plastic cable ducts in different sizes and shapes.

Plastic boxes come in a range of sizes, shapes, and colors, so you can select the ideal kind of cable channel to address any issue. They are made of a plastic that has a variety of qualities, such as improved fire safety and water resistance. High-quality plastic performs well in the environment, poses no health risks, and doesn’t contain any dangerous volatile compounds.

The availability of a wide variety of fittings, such as plugs, couplings, and external and internal corner adapters, is a major benefit of plastic wiring boxes. All of this considerably eases the installer’s work, expedites the installation process, and provides a polished appearance for the power line.

Manufacturers create a range of plastic box fittings and accessories to give the cable route a polished, aesthetically pleasing appearance.

Plastic is very easy to maintain, does not gather dust, is washable, and can be quickly replaced when needed, among other things.

How to calculate the size of the cable channel

In order to correctly select the size of the cable channel, you need to know in advance the number of wires that will be located in it. In a word – you need a well thought-out electrical scheme, a working project, in accordance with which the electrical equipment is purchased. Usually, the volume of the box is determined based on the cross-section of the cables in it. An allowance is added to it (if necessary) for laying two or three wires in the future. It is not a secret that over time our homes are getting more and more new types of communications. Just yesterday no one heard about the Internet, and today it is in every home, which means that there is a need to run one more additional cable to the desktop.

For future network expansion, you can, if needed, reserve two or three wires in the cable channel.

The purpose of the wires that will be housed in the box must be considered when choosing one. Therefore, purchasing a metal or hermetic cable duct is not required for low-current cables. Additionally, there’s no need to spend money on a heat-resistant box because the tiny currents carried by computer, television, and phone cables don’t pose a fire risk. However, the highest level of protection against short circuits is required when installing power lines, so hermetic and non-combustible material are appreciated.

Types of fixing the cover of the cable channel

The installation cable duct cover needs to be firmly secured to the box. For this, many tools and techniques are employed.

  1. In metal boxes most often used screw fasteners – bolts, screws, as well as – clamps and snaps.
  2. In plastic products, the most common fastening is by means of latches or tight fitting of the lid on the main body.

The cover of plastic boxes is typically secured by latches located in the body’s grooves.

When paired with other interior components, cable ducts are particularly fashionable these days. A striking illustration of this symbiosis is a skirting board made of plastic or wood that has a space inside for cables to be laid. This holds true for both ceiling-mounted and floor-mounted skirting boards.

It is convenient to install new cables in the room’s designated floor skirting board channels.

The plinth’s ability to have its top cover removed and to add or remove wires as needed, provided there is still room to do so, makes it even more convenient. It is important to take caution not to harm the plastic grooves where it is attached.

There is no cover for wooden skirting boards, and the wire can only be laid once, during installation.

Cable installation in a wooden skirting board can only be done when a room is being renovated.

The installation box’s resistance to combustion is one of its key features. In this regard, metal cable ducting is far superior to all other materials. Simultaneously, plastics that hinder combustion and are "self-extinguishing"—that is, capable of being installed in wooden skirting boards and putting out the ensuing fire—have been developed and tested. Although these products are a little more expensive, safety shouldn’t be compromised in areas where fire hazards are higher. The product’s technical passport provides clarification on the cable channel’s compliance with the requirements that are currently in place.

Federal Law No. 123, "Technical Regulations on Fire Safety Requirements," is the document that governs fire regulations for installing cable ducts and cables. The primary prerequisites are outlined in Article 82, Items 6, 7, and 8, as well as in the "Code of Regulations 6.13130.2009." created by the Russian Ministry of Emergencies.

Cable duct manufacturers

The need for cable ducts has increased to previously unheard-of levels since the idea was developed and authorized by lawmakers. As such, all of the top electrical companies have set up this kind of product’s production and sales. Every kind of channel has undergone rigorous certification and testing, so the data on the mounting box’s technical data sheet can be relied upon.

Among the well-known foreign companies, LEGRAND, SIMON ELECTRIC, FERON, and other companies are deserving manufacturers.

Several domestic manufacturers stand out, including "National Electrotechnical Company Morozov," "ERA," "ROSEL," and numerous others.
