Lights dim when appliances turn on — Alicante, Valencian Community
If lights flicker or noticeably dim every time a large appliance kicks on — the AC compressor, dryer, microwave, or vacuum — your electrical system is struggling to deliver enough power. This is called voltage drop and usually points to an undersized circuit, a loose connection, or an electrical panel that can't keep up with modern demand. Ignoring it risks overheating wires, tripped breakers, and in severe cases, an electrical fire. A licensed electrician can measure the voltage drop, tighten connections, add a dedicated circuit for the offending appliance, or recommend a panel upgrade.

Spanish REBT requires boletines eléctricos for all installations signed by a registered instalador autorizado. Many buildings still have outdated aluminum wiring in communal areas from 1970s–1980s construction.
