Housing - on-wall-ceiling | Electrical material

Do you want to bring together several electrical cables for your electrical installations? In this catalog you will find housings that have been developed for mounting on a wall or ceiling. These are mainly referred to as junction boxes, junction boxes, connection boxes, distributor boxes or, according to German standards, as installation boxes. Find out here what the differences are between the individual installation boxes and which criteria are relevant when purchasing.

With eibabo®, you can choose exactly the installation boxes that are best suited to your project from a comprehensive range. These are also referred to as passive components of an electrical installation and, in contrast to switch boxes, are mostly installed on plaster. Due to their design, these are designed for stationary installation and for accommodating cables, lines, clamps and other connections. We carry housings with strain relief lugs for pendant lights and external mounting lugs. You will also receive housings with high resistance to the effects of weather. These are impact-resistant, protect against rainwater and are also resistant to changing temperatures and seawater. Housings with these special properties are approved for installation on ships and for offshore applications.

Notice:

Always leave electrical installations to an experienced electrician. When working on an installation box, safety always comes first. Disconnect the relevant circuit from the power supply.

A high percentage of the junction boxes at eibabo® are kept in classic white and grey. However, you can also find cases in colors like black, green, brown, and red for a more customized use.

What do I need installation boxes for?

Junction boxes are an essential part of the electrical wiring systems for houses and other buildings. These are made of metal or plastic and protect cable connections, connections and distributions in an electrical installation. For example, if you want to distribute the individual supply line for a room to several lines, the wiring is done in the installation box.

How are installation boxes installed?

The assembly of the installation boxes is very simple. As a rule, the housings have markings or screw channels on the inside, which you should use to attach them to stable and secure surfaces. Some variants offer external attachment tabs. Make sure that the housing corresponds to the conditions at the place of use, is freely accessible for maintenance work and cannot be manipulated by unauthorized persons.

TIP:

You can close and seal some installation boxes tightly. External influences can be quickly identified through the viewing window in the cover.

TIP:

Based on experience, we recommend that you make the entries for each cable before installing the socket and insert cables as a test.

In tight installation environments, it can be difficult to cut out post-inserts or expand existing diameters.

How do installation boxes differ?

Installation boxes differ mainly in size, material and properties for specific locations. Installation boxes can be made of either metal or plastic. The choice between plastic and metal depends on which cable material is used and which mechanical loads an installation box should be able to withstand. Metal-sheathed cable and metal conduit typically require a metal junction box for grounding. Even if the installation box is exposed to heavy knocks or similar influences in everyday life, a stable metal model is recommended. Plastic housings are the standard choice for non-metallic cables.

Special features

Some models are fire resistant or shielded for use in severe conditions. Installation under the ground, under water or in potentially explosive areas is also possible in some cases.

Check the local regulations for your electrical installation. This will tell you if you need to use wall outlets with a specific IP rating. In most cases, your electrician can tell you what IP rating is required.

Correct dimensioning of the installation box

The dimensioning of an installation box is crucial to ensure the function of the internal connections. If you have enough space available, we always recommend using a slightly larger can. Cables and wires are rigid and difficult to bend into shape. Clamps require space. If you choose the socket too small, the space for working on the connections will also be very small and cramped. When determining the size, consider:

the number of lines to be installed
the length of the lines for comfortable work
the cross-section of the lines and the associated flexibility
the number of clamps to be installed
any other components in the can

TIP:

Do not leave any exposed wires in the installation box. Even if you do not need a wire, please always provide it with a clamp.

Always allow for some reserve for changes in the future. On average, installation boxes for commercial use are larger than housings for private households, as these often have to accommodate more connections.

How do I find the right installation box?

There is a large selection of installation boxes. This ranges from universal installation boxes to special products. You will find the right product if you ask yourself the following questions:

Do I need an installation box for commercial or private use?
What are the site conditions like? (surface, temperature, humidity, electromagnetism, risk of impact)
How much space do I have for installation?
What is installed in the can and how much?
What space should I reserve as a reserve?
Do I want to secure the installation box? (vandalism, unauthorized access, sealing)

The answers result in a catalog of properties. You can easily set these as a filter here in the shop. With many secure payment methods, fast delivery and worldwide shipping, the eibabo® technology store is your competent specialist dealer for all questions relating to electrical installation.
