Essential Categories of Installation Material and Their Applications
The world of installation material is vast and includes numerous components, each with a specific function within the electrical infrastructure. Knowing the main categories will help you find the right products for your project.
Cables and Wires: The Lifelines of Your Installation
Cables and wires transport electricity throughout your installation. There are various types, each suited for specific applications:
Installation Wires: Used inside conduits and pipes to connect switches, sockets, and lighting. Available in various colours for live, neutral, earth, and switch wires.
Underground Cables: Specially designed for underground installation, waterproof and robust. Essential for outdoor lighting or connections to garden sheds.
Coaxial and Network Cables: For data and television transmission, often installed alongside electricity cables for a complete setup.

Switching and Connection Material: Control and Connection
This category includes all the components needed to operate your electrical appliances and make connections:
Switches: For turning lighting and other electrical circuits on and off. Variants include single-pole, double-pole, two-way, and intermediate switches.
Sockets (wall sockets): Provide connection points for electrical appliances. Available in surface-mounted and flush-mounted versions, with or without earthing.
Plugs and Sockets: For a safe and reliable connection between appliances and the mains.
Dimmers: These allow you to control the light intensity of dimmable lamps, contributing to ambiance and energy savings.
Distribution and Protection Devices: The Heart of the Installation
The meter box or consumer unit is the central point of your electrical installation, where power is distributed and protected.
Consumer Units (fuse boxes): This is where all electrical circuits come together and are protected against overload and short circuits.
Residual Current Devices (RCDs): An essential safety component that interrupts the power supply in case of a leakage current, preventing electrocution.
Circuit Breakers (fuses): Protect specific circuits in your electrical installation against overcurrent.

Fixing Materials and Tools: For a Neat Finish
To install all components neatly and safely, various tools and fixing materials are required:
Conduits and Boxes: Protect cables and provide space for connection points. Think of ceiling boxes, flush-mounted boxes, and junction boxes.
Cable ties and clips: For securing and organising cables.
Terminal blocks and wire connectors: For safely connecting wires.
Draw tapes (fish tapes): Essential for pulling wires through conduits.
Sensors and Smart Components: The Future of Lighting
Modern installations increasingly integrate smart technology for greater comfort and energy efficiency:
Motion sensors: Automatically switch on lighting upon detecting movement, ideal for outdoor lighting or hallways.
Dusk-to-dawn sensors: Ensure lighting turns on at dusk and off at daylight.
Smart plugs and switches: Make existing lighting smart and control it via an app or voice assistant.
Power adapters and drivers: Essential for LED lighting that operates on a lower voltage (e.g., LED strips).
Safety and Regulations: Important Considerations for Installation Material
When working with electricity, safety is paramount. All electrical installations must comply with strict national and European standards, such as NEN 1010 in the Netherlands and the AREI (General Regulations for Electrical Installations) in Belgium.
IP ratings: This classification indicates the degree of protection against ingress of dust and water. For outdoor lighting or damp areas (bathrooms, kitchens), specific, higher IP ratings are required. For example, an IP44 rating means splash-proof, while IP65 means jet-proof and dust-tight.

Earthing regulations: Correct earthing of all metal parts and electrical equipment is essential to prevent electric shocks.
Current regulations: Always check the most recent version of the applicable installation standards. There are regular updates, such as the recent changes to the AREI in March 2025, which set new requirements for bathrooms and sockets, among other things. These updates contribute to a more modern and safer electrical installation. [Reference: Official website AREI / NEN 1010].
Choose the Right Installation Material: Tips for Your Project
The choice of installation material depends heavily on the nature and scope of your project. Here are some practical tips to get you started:
Determine the purpose: Are you installing a new system, extending an existing one, or renovating? This determines the required materials and complexity.
Create a detailed plan: Draw out your electrical layout, including the positions of switches, sockets, and light points. This will help you calculate the required quantities and types of material.
Check compatibility: Ensure that all components you purchase are compatible with each other and with your existing installation (e.g., dimmers with dimmable lamps, or LED drivers with the correct voltage).
Opt for quality: Cheap is often expensive in the long run, especially with electrical materials. Invest in certified products from reliable brands to ensure safety and longevity.
Consult a professional: In case of doubt or complex projects, it is advisable to hire a certified electrician. They will ensure a safe and compliant installation.

Frequently Asked Questions about Installation Material
What causes flickering lights or a tripping fuse?
Flickering lights can indicate an overloaded circuit, loose connections, or problems with the lamp itself. A frequently tripping fuse almost always points to an overload, short circuit, or a faulty appliance on that specific circuit. This requires investigation and possibly modifying the installation or replacing the faulty fuse or breaker.
When is an upgrade of my consumer unit needed?
An upgrade of your consumer unit is often necessary when you increase your home's electricity consumption, for example, by installing solar panels, a heat pump, an electric car charging station, or heavy kitchen appliances. Older consumer units may also no longer meet current safety standards and may require an upgrade for safe operation and to maintain insurability.
Can I connect installation material myself?
Simple tasks, such as replacing a switch or socket, can be performed by a handy person, provided the power is turned off and the applicable safety regulations are strictly followed. For more complex work, such as adding new circuits, replacing the consumer unit, or laying new wiring, hiring a certified electrician is highly recommended. Errors in electrical installations can have serious consequences, ranging from fire to electrocution. When in doubt, always prioritize safety.
