Imagine a home where every lamp, socket and charger has its own place. Everything is tidy, safe and peaceful. However, there are moments when adding a new circuit feels like a battle with cables, walls and a chaotic distribution box. Because of that, choosing the right distribution board really matters.
A good electrical panel is the foundation of a well-designed installation. Therefore, with Hager boards available at Preis-Zone, you get solutions that offer long-term peace of mind.
In this article, I’ll show you how to choose the right modular distribution board. For example, you’ll learn when a surface-mounted, flush-mounted, protected, pre-wired or empty enclosure will work best for your home, workshop or small project.
Why the distribution board matters: function and safety
The distribution board is the heart of your electrical system. It is where circuits, protection devices and cables “meet”. When chosen wisely, it offers several clear benefits:
-
You gain order and clarity, and as a result, future upgrades become much easier.
-
Your system becomes safer and compliant with standards, which reduces the risk of short circuits or overloads.
-
You also get more comfort during use and maintenance. Access to modules is easier, and cable organisation becomes simpler.
In fact, treating a distribution board as “just a box for cables” is risky. It’s better to design it properly from the start.

Types of Hager distribution boards — what to choose
In our online store, you’ll find various Hager models. They differ in mounting method, purpose and level of complexity. Because of this, it’s important to choose a board that fits your installation.
♠ Flush-mounted modular distribution boards
These boards are installed inside the wall. They are popular in homes and apartments because they keep the installation discreet.
Example: Hager 4-row board with 48 modules.
Benefits: neat appearance, hidden components, and a clean, modern interior.
♠ Surface-mounted modular distribution boards
These boards are mounted directly on the wall. Therefore, they are ideal for garages, workshops, basements or renovations.
Example: Hager VA12BN — a 1-row, 12-module enclosure.
Benefit: easy access and high flexibility.
♠ Empty enclosures
If you want to build your own setup — for example, with custom protection devices or PV installation — an empty enclosure is a great choice. It offers full flexibility and allows step-by-step installation.
♠ Pre-wired distribution boards
Hager also offers complete boards that are ready to connect. As a result, you save time and avoid configuration mistakes.
Benefits for the user
A well-chosen Hager board offers clear advantages:
-
Order and clarity — each circuit has its place.
-
Safety — proper protection reduces the risk of failures or fire.
-
Flexibility — the system can grow with your needs.
-
Easy installation and servicing.
-
Aesthetics — especially with flush-mounted models.
Common mistakes — and how to avoid them
Mistake: Choosing a distribution board that’s too small — this leads to clutter and no room for future circuits.
Solution: Always plan with extra space (additional modules, wiring capacity, protective devices).
Mistake: Using a surface-mounted board where a flush-mounted one would be better (or the other way around) — affecting aesthetics, accessibility and protection.
Solution: Match the mounting type to the location and its function.
Mistake: Not planning for future expansion (e.g. extra lighting, garden power, PV installation) — which often results in needing to replace the entire board.
Solution: From the beginning, assume a “version 2.0” scenario.
Mistake: Poor cable organisation, overloaded circuits or missing protection devices — all of which increase the risk of failure.
Solution: Arrange wiring logically, use proper modular devices and calculate loads in advance.

Application scenarios
1. Single-family home / apartment
If you want to add sockets, lighting or protection for kitchen and bathroom circuits, choose the Volta 4×12. This way, everything stays tidy and future-proof.
2. Garage / workshop
A surface-mounted VA12BN or modular enclosure works best. In addition, it’s easy to expand.
3. Future-ready installation
Start with an empty enclosure. Add devices step by step. As a result, your system will grow with your needs.
FAQ — the most common questions, answered quickly
Q1: Is a surface-mounted board suitable for an apartment?
A: It can be used, but if you care about aesthetics and a hidden installation, the flush-mounted version is the better choice. Surface-mounted boards fit garages, basements and workshops better.
Q2: Can I buy an “empty” distribution board and wire it later?
A: Yes — Hager offers empty enclosures/modular boards that you can equip at any time. Perfect for phased installations or systems that need the option to expand.
Q3: How do I choose the right size (number of modules)?
A: Count all planned circuits + add a safety margin (for future sockets, lighting or additional circuits). A slightly larger board is better than running out of space.
Q4: Will a Hager distribution board ensure a safe, standard-compliant installation?
A: Yes — Hager is an experienced manufacturer, and their boards and protection devices meet building installation standards.
Q5: What if I need to expand later — can I change only part of the board?
A: With modular or empty enclosures — yes. You can add more rows/modules or switch to a larger enclosure. It’s always wise to plan ahead with some reserve.
Summary — your first step toward a reliable installation
Choosing the right distribution board is not a minor detail — it’s the foundation that determines the safety, comfort, and scalability of your electrical installation.
Hager distribution boards, available at Preis-Zone, offer a wide range of solutions: from compact surface-mounted enclosures, through elegant flush-mounted units, to empty housings ready for any configuration.
If you’re planning a house, apartment, garage, or workshop, ask yourself:
how many circuits do you need, can the installation grow in the future, do you care more about aesthetics or functionality? Choose a solution with room to expand — it’s an investment that pays off in comfort and long-term safety.
