Installation boxes

Installation boxes - an essential element of every electrical installation

Junction boxes are a key component of electrical systems in buildings.   Their role is often underestimated, but it is they who ensure safe and correct cable connections. At Onninen we offer a wide selection of junction boxes from renowned manufacturers.

Our portfolio includes products from brands such as Kontakt-Simon, Simet, F-Elektro, Kopos and Elektro-Plast Nasielsk. Each of them has unique features and advantages. Our specialists will be happy to advise you in choosing the optimal solution.

Types of junction boxes available in the Onninen offer

Our range includes various types of boxes, adapted to specific installation needs:

• Flush-mounted boxes
• Electronics boxes
• End boxes and wall boxes
• Very deep boxes and for concreting
• Four- and five-pole boxes
• Deep boxes (with screws, without screws, combined)
• Lid cans and plate cans

Each type of junction box has its own unique application and features.   Flush boxes are ideal for concealed installations in walls. Electronics boxes provide additional protection for delicate components.

End and wall boxes are used for mounting lighting fixtures. Very deep boxes and boxes for concreting are suitable for specialist building installations.

In everyday practice, we often come across questions about the differences between types of boxes. It is worth knowing that four- and five-pole boxes allow for the installation of a larger number of modules. This is useful in extensive installations.

Deep boxes, on the other hand, provide more space for wires and connectors. They are available with or without screws, as well as in a combined version. This gives flexibility in choosing the specific needs of the project.

Criteria for selecting installation boxes - what to pay attention to?

Selecting the right junction box is crucial for the safety and functionality of the installation.   At Onninen we advise clients to take several important factors into account:

1. Type of installation (concealed, surface-mounted, in concrete)
2. Required box depth
3. Number of assembly fields required
4. IP protection class
5. Fire resistance (if required)

In our experience, the IP protection level is often overlooked. This is a mistake, especially in humid rooms. Boxes with a higher IP will provide better protection against moisture.

Recently, in a project for a large office complex, we advised the use of boxes with increased fire resistance. This is crucial for safety in high-rise buildings.

In the case of office reorganization, we most often recommend boxes with a larger number of fields. They provide freedom in the event of future expansion of the installation. This saves time and costs in the long run.

Practical applications of junction boxes in various environments

Junction boxes are used in almost every type of building and installation.   In single-family homes, standard flush-mounted boxes are most often used. In offices and commercial spaces, boxes with more fields work well.

In industrial environments, resistance to harsh conditions is key. Here, we recommend boxes with a high IP protection level. They provide safety in the presence of dust or moisture.

An interesting example is installations in historic buildings. Here, we often use plate boxes. They allow for installation in thin walls without damaging their structure.

In modern, smart homes, electronics boxes are essential. They protect sensitive components of automation systems. This is important for long-term and trouble-free operation of the smart home.

Many customers ask us about solutions for humid rooms, such as bathrooms or laundries. In such cases, we recommend boxes with increased IP. They prevent moisture from entering the installation.

At Onninen we offer comprehensive advice on the selection of installation boxes.   Our experts will help you choose the best solutions for each project. We invite you to contact us and take advantage of our experience in electrical installations.
