Electrical installations in hollow partitions are one of the most common and efficient solutions in construction and renovations. However, to ensure they are safe, functional, and durable, it is essential to follow a series of guidelines and use the appropriate materials.
In this article, we explain everything you need to know about this type of installation, from the basic concepts to the technical keys, and how products from the Blue Series by Solera can simplify the process.
What is a hollow partition and why is it ideal for electrical installations?
A hollow partition is a thin wall, generally constructed with materials such as plasterboard, gypsum, or hollow brick, used to divide interior spaces. Its main feature is the internal cavities that allow cables, pipes, and other elements to pass through without the need for major structural work.
Why is it ideal for electrical installations?
-
Conceals cables: Eliminates the need for external conduits, maintaining the aesthetic of the space.
-
Saves time and costs: Since complex construction is not required, installation time and associated expenses are reduced.
-
Provides flexibility: It is easier to make modifications or expansions in the future.

Key points for a safe and efficient electrical installation in hollow partitions
Planning and design
Before starting any work, it is essential to create a detailed plan that includes:
-
Location of electrical elements: Outlets, switches, lighting points, and special devices (such as network sockets or home automation systems).
-
Circuit distribution: Separate circuits according to their function (lighting, outlets, appliances) to avoid overloads.
-
Use of blueprints: Draw a schematic of the space to visualize the installation and prevent placement errors or interference with pipes or other structures.
Selection of appropriate materials
The quality of the components is critical to ensuring safety and durability. Consider:
-
Cables and conductors: Use gauges appropriate to the required power (e.g., 1.5 mm² for lighting, 2.5 mm² for outlets).
-
Protective conduits: Opt for corrugated tubes or conduits that are fire-resistant and impact-resistant, protecting cables from moisture and abrasion.
-
Installation boxes: Choose boxes specifically for hollow partitions, designed to be securely anchored and to house electrical devices (outlets, switches) without deforming the wall.
Protection and organization of cables
In hollow partitions, cables must always be protected and organized:
-
Avoid loose cables: Use corrugated tubes to group and insulate the cables, facilitating future replacement.
-
Protect connections: Use watertight connection boxes for splices, avoiding short circuits due to dust or moisture.
-
Minimum distances: Keep cables away from heat sources (such as heating pipes) and maintain a safety distance of at least 15 cm from corners and wall edges.
Secure fastening of components
A stable installation prevents long-term failures:
-
Anchoring of conduits and cables: Fasten corrugated tubes to the partition with clamps or plastic ties every 50-60 cm to avoid movement.
-
Securing boxes: Use boxes with adjustable fastening systems (such as expanding legs or anchoring screws) that adapt to the thickness of the partition without damaging it.
-
Reinforcement in critical areas: In areas with vibrations (near doors or windows), add metal supports for extra stability.
Compliance with regulations and final tests
Always follow local regulations and perform verifications:
-
Key regulations:
-
Installation of earth connections on all circuits.
-
Use of residual current devices (with sensitivity ≤30 mA).
-
Protection against overvoltages with varistors or specific devices.
-
-
Mandatory tests:
-
Verification of electrical continuity.
-
Measurement of insulation resistance (values ≥1 MΩ).
-
Checking the operation of switches and outlets.
-
Tools needed for the installation
To carry out an electrical installation in a hollow partition, you will need tools such as:
-
Cable and pipe detector: To avoid damaging other installations when drilling.
-
Drill with a long bit: To make the necessary holes in the partition.
-
Level and measuring tape: To ensure the correct alignment of the elements.
-
Wire stripper and crimper: To properly prepare the cables.
Practical tips for a successful installation
-
Avoid overloading circuits: Distribute the electrical load evenly to prevent issues.
-
Test the installation before closing the partitions: Verify that everything works correctly before finalizing the project.
-
Consult a professional: If you lack experience, it is advisable to hire a certified electrician to ensure the installation's safety.
