Lights dim when appliances turn on — Dordrecht, South Holland
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.
Why this is common in Dordrecht
The mix of medieval-core monuments and post-war and 20th-century suburbs means electricians swing between careful upgrades in listed canal houses (where surface wiring and panel work must respect heritage rules) and standard rewires plus the growing wave of EV chargers, heat-pump circuits and solar tie-ins across the outer neighbourhoods.
