An external electrical system, visible on the wall and not recessed, can be an interesting stylistic choice—easier and less expensive to implement than you might think. However, it is essential to carefully consider the advantages and disadvantages in order to make the right choice.
In the world of design and interiors, exposed electrical systems have become a popular choice for those wishing to combine functionality with aesthetics. Especially in homes with a vintage or industrial style, a well-designed external electrical system not only meets practical needs but also adds a distinctive touch to the space. The advantages are therefore numerous, including: aesthetic appeal, ease of installation, and the possibility of making changes without the need for building work. However, safety must not be overlooked. It is essential to rely on qualified professionals for a safe installation that complies with all regulations. Even an exposed electrical system, in fact, can be dangerous if not installed correctly. In this guide, we explore the pros and cons to consider before installing an external electrical system.
What requirements must an outdoor electrical system meet?
An exposed electrical system offers the advantage of not requiring major building work for installation, making it well-suited even for attics, garages and storage rooms.
Even at home, it is perfect for those seeking a vintage and industrial style. Whether in domestic or commercial settings, it must be made in accordance with regulatory standards to ensure safety and efficiency. It is therefore important to guarantee safety by relying on specialised technicians with the necessary certifications.
Unlike traditional systems, this type is installed on the outside of walls and does not require chasing, allowing for quicker installation without demolition. However, quality and compliance with standards must be just as, if not more, rigorous.
What requirements must an outdoor electrical system meet?
Creating an exposed electrical system requires attention to detail and careful planning. The first step is to choose the cable route, which should harmoniously blend with the room’s aesthetic. Surface-mounted electrical conduits are essential in this context: available in various materials and finishes, they allow you to conceal cables while ensuring easy access and maintenance. The solution by Creative Cables for a safe, customisable and designer exposed system is the one with Creative Tubes, the flexible, fabric-covered conduits.
What cable cross-section should be used for outdoor electrical installations?
Choosing the right cable cross-section is crucial for the safety and efficiency of your outdoor electrical system. To avoid risks such as overheating, it is essential to select cables with the appropriate cross-section according to the expected electrical load and the length of the run. Large cross-section cables are definitely a good starting choice, which should be assessed by whoever is installing the system.
Vintage surface-mounted electrical system
For those who love a retro or vintage style, exposed electrical systems can become a defining design feature. By using fabric conduits, as well as switches, electric sockets and porcelain components, it’s easy to achieve a look that best complements period furnishings and decorations.
What regulations must be followed to install an exposed electrical system?
In general, the regulations to be followed are the same as those for recessed systems. One must navigate laws listing minimum safety requirements, decrees establishing criteria and materials for electrical installations, and standards regulating installation work. Some are valid at European level, others are defined by each country. Given the complexity, it is essential to rely on specialised technicians to ensure a safe and legally compliant installation.
What are the costs for an outdoor electrical system?
The cost varies depending on several factors, such as location, the size and complexity of the system, the type of property, and the number of desired light points. For example, for a 70 sqm house with around 40 light points, the cost is approximately 50-80 euros per point, for a total of about 2,000/3,500 euros. However, the choice of high-quality materials and other factors can also significantly influence the final cost.
External electrical system: pros, cons and tips
Among the reasons for choosing a surface-mounted electrical system, there are certainly three:
- Can also be installed in listed buildings
- Ease of creation, modification and maintenance
- The vastness of choice in a design that adds character.
Before installing an exposed electrical system, however, it’s important to consider that special attention must be paid to the materials used, given the increased exposure to external factors.
In conclusion, an external system is ideal for homes with constraints and for those who love a vintage or industrial style. But it's also perfect for anyone looking for a quick and affordable solution in spaces such as garages and attics. The cost varies depending on the materials and design chosen, and safety is guaranteed if the system is installed according to regulations.
