Home safety starts with the electrical system. Many houses built before the 1990s feature outdated wiring, not designed to support the energy load of modern appliances. Ignoring signs of wear can lead to serious consequences, from constant blackouts to the risk of fires.
""Over 30% of house fires are caused by short circuits, overloaded outlets, or malfunctions in old, non-compliant electrical systems.""
If your house is more than 25-30 years old and the system has never been inspected, requesting a technical check is crucial. Regulatory compliance protects your family and increases your property's value.
Recognizing a faulty or overloaded system in time is vital. Many problems hide behind the walls, but there are obvious symptoms you should never ignore. Here are the 5 signs you must pay close attention to:
The 5 Warning Signs
- Frequent circuit breaker trips: If the differential switch trips often without apparent reason, there is likely a constant overload or a dangerous current leakage.
- Warm outlets or switches: Wall faceplates should never overheat. Excessive heat indicates a bad connection or electrical wires too thin for the current they carry.
- Burning smell or small sparks: If you notice an acrid smell near outlets or see sparks when plugging something in, immediately turn off the main switch and call a professional.
- Flickering lights: Sudden voltage drops, especially when turning on a large appliance (like an oven or washing machine), indicate the system is at the limit of its capacity.
- Lack of grounding: Old systems often lack the grounding wire (the yellow-green one), which is essential for discharging leakages and saving lives in the event of an electric shock.
Never rely on DIY when it comes to electricity. Turning to qualified technicians ensures a state-of-the-art renovation, executed safely, and includes the issuance of the legally required Declaration of Conformity.
