Electrical Inspection

An electrical inspection is a systematic examination of a building's electrical installation to verify safety, code compliance, and proper function. In Finland, electrical installations must be inspected upon completion (acceptance inspection), and existing installations in residential buildings should be periodically assessed to identify aging, damage, or non-compliant modifications. The inspection covers the electrical panel, wiring, outlets, switches, grounding, and protective devices.

Electrical systems age and deteriorate over time. Insulation materials become brittle, connections loosen, and older installations may not include modern safety features such as residual current devices (RCDs). Buildings from the 1960s through 1980s may contain aluminum wiring, which requires special attention due to its higher resistance and tendency to loosen at connections. An electrical inspection identifies these issues before they cause fires or shock hazards.

A comprehensive electrical inspection evaluates the capacity of the main panel (is it adequate for current demands?), the condition of branch circuit wiring, the presence and function of protective devices (breakers, RCDs), the grounding system integrity, the condition of outlets and switches, and compliance with current safety codes. The inspector provides a written report with findings and recommendations prioritized by urgency.

An electrical inspection is especially important before purchasing a home, before major renovations, when appliances trip breakers frequently, when lights flicker, or when the installation is more than 30 years old without an update. All remedial electrical work identified in the inspection must be performed by a licensed electrician. Investing in an electrical inspection provides peace of mind and can prevent the devastating consequences of an electrical fire.
