A circuit breaker that trips repeatedly is a warning sign that should not be ignored. The most common causes are an overloaded circuit (too many appliances drawing power simultaneously), a short circuit (damaged wiring or a faulty appliance), or an insulation fault in older wiring. The first step is to unplug all devices on the affected circuit and attempt to reset the breaker. If it trips again immediately, the problem is likely in the wiring itself. Never force a breaker to stay on, as this creates a serious fire risk. A qualified electrician will carry out a full diagnosis using specialised testing equipment to identify the exact cause — whether it is a specific appliance, a degraded cable, or an undersized breaker. The repair is then targeted and documented.

Yes, full electrical compliance upgrades are carried out according to current Luxembourg regulations. Many older properties have installations that no longer meet modern safety requirements — missing earth connections, absent or outdated RCD protection, undersized cabling, or panels with obsolete fuse holders. A compliance upgrade begins with a thorough diagnostic inspection to identify all non-conformities. The work typically includes replacing the electrical panel with a modern unit featuring 30 mA RCD breakers, verifying and upgrading the earthing system, adding surge protection, and rewiring any circuits that present a risk. After the upgrade, an inspection certificate is issued confirming that the installation meets current standards. This is particularly important when selling or renting a property, and essential for insurance validity. A free quote is provided before any work begins.

Yes, home EV charging stations (wallbox) are installed for all electric and plug-in hybrid vehicles. The process begins with an assessment of your existing electrical installation to determine whether the panel can support the additional load, or whether an upgrade is needed. Chargers are available in 7 kW (single-phase) and 22 kW (three-phase) configurations, with the optimal choice depending on your vehicle's onboard charger capacity and your daily driving habits. The installation includes a dedicated circuit with appropriate protection, wall mounting of the unit, and full commissioning. The Klimabonus 2026 programme provides a subsidy of €1,200 for 1 to 3 parking spaces and €1,650 for 4 or more. Guidance on the subsidy application is provided as part of the service. A clear, itemised quote is presented before installation begins.

A comprehensive electrical diagnosis typically takes 1 to 2 hours, depending on the size and complexity of the installation. The specialist systematically tests every circuit in the property using professional measuring equipment: continuity testing to verify conductor integrity, insulation resistance measurement to detect degraded wiring, earth loop impedance to confirm effective fault protection, and RCD trip testing to ensure personal protection devices respond correctly. The panel is inspected for proper labelling, adequate breaker sizing and the presence of surge protection. At the end of the diagnosis, a detailed written report is provided listing all findings, ranked by priority — from critical safety issues requiring immediate attention to recommended improvements for long-term reliability. This report serves as a solid basis for planning any upgrade work and obtaining an accurate quote.

The cost of installing a home EV charging station depends on the charger power output and the state of your existing electrical installation. A 7 kW single-phase wallbox is suitable for most daily charging needs and is the most affordable option. A 22 kW three-phase charger offers faster charging but requires a three-phase supply and may necessitate a panel upgrade. The installation includes a dedicated circuit, appropriate protection devices, wall mounting and full commissioning. The Klimabonus 2026 programme provides a subsidy of €1,200 for residential properties with 1 to 3 parking spaces, and €1,650 for 4 or more spaces. This subsidy significantly reduces the net cost. A free on-site assessment determines the optimal configuration for your property, and a transparent, itemised quote is provided before any work begins.

An electrical compliance certificate is mandatory for all new installations and major modifications to existing installations in Luxembourg. The certificate confirms that the electrical system meets current safety standards, including proper earthing, adequate RCD protection, correct cable sizing and appropriate circuit breaker ratings. For older properties, a compliance check is strongly recommended — especially when selling, renting, or renovating. Insurance companies may also request proof of compliance in the event of a claim related to an electrical fault. The inspection covers the entire installation from the meter to the last socket, with particular attention to bathrooms, kitchens and outdoor circuits where the risk of electric shock is highest. A qualified electrician carries out the necessary upgrades and arranges the official inspection, providing a complete turnkey service from diagnosis to certified compliance.

Yes, commercial electrical installations are fully covered. This includes retail shops, offices, restaurants, warehouses and light industrial premises. Services range from commercial lighting design and installation (LED panels, track lighting, emergency lighting) to full electrical fit-outs for new premises. Compliance upgrades for commercial panels are carried out to meet the specific requirements of commercial properties, including three-phase distribution, dedicated circuits for high-power equipment and structured cabling for data networks. Regular safety inspections are available to ensure ongoing compliance with Luxembourg regulations. For restaurants and food service businesses, installations must meet additional hygiene and safety standards. A specialist works with the business owner to minimise disruption, scheduling work outside business hours where possible. A detailed quote is provided after an on-site survey of the premises.

A circuit breaker (MCB) and an RCD (residual current device) serve two fundamentally different protective functions in an electrical installation. The circuit breaker protects the wiring and equipment against overloads (too much current drawn) and short circuits (a direct fault between live and neutral). It disconnects the circuit before the cable overheats and becomes a fire hazard. The RCD, on the other hand, protects people against electrocution by detecting tiny imbalances in current flow — as small as 30 milliamps — which indicate that current is leaking through a person's body or through damaged insulation to earth. Both devices are essential: the circuit breaker prevents fires, while the RCD prevents fatal electric shocks. Modern electrical panels in Luxembourg combine both types, often as RCBO units that provide dual protection on a single circuit.
