sähkökaappi

A sähkökaappi, which translates to "electrical cabinet" or "fuse box" in English, is a common component in Finnish homes and buildings. It serves as the central distribution point for electricity within a property, housing essential safety devices and controls.

The primary function of a sähkökaappi is to protect the electrical system from overloads and short circuits. Inside, you will typically find circuit breakers or fuses. Circuit breakers are modern safety devices that automatically interrupt the flow of electricity when an abnormal current is detected. Fuses are older safety devices that contain a wire designed to melt and break the circuit if the current becomes too high.

The sähkökaappi also contains the main switch for the entire electrical installation, allowing for the complete disconnection of power if necessary. Additionally, it houses individual circuit breakers or fuses for different areas or appliances within the building, such as lighting circuits, socket circuits, and specific appliance circuits.

Proper installation and maintenance of a sähkökaappi are crucial for electrical safety. It should always be installed by a qualified electrician. Access to the sähkökaappi should be unrestricted but also protected to prevent accidental tampering. In case of any electrical issues or power outages, the sähkökaappi is the first place to check for tripped breakers or blown fuses.
