päätaulun

Päätaulun is a Finnish term that translates to "main board" or "distribution board" in English. It refers to the central electrical panel in a building where the incoming electrical supply is distributed to various circuits throughout the property. This board houses the main circuit breaker, which serves as the primary safety device to disconnect all power to the building in case of an emergency or for maintenance.

Within the päätaulun, individual circuit breakers or fuses are located. Each of these protects a specific circuit, such as those for lighting, outlets, or appliances. If a fault occurs on a circuit, such as a short circuit or overload, the corresponding breaker will trip, interrupting the flow of electricity to that specific area and preventing damage or fire. This compartmentalization ensures that a problem in one part of the electrical system does not affect the entire building.

The päätaulun is a critical component of any electrical installation, ensuring safety and proper distribution of power. It is typically installed in a readily accessible location, such as a basement, garage, or utility room, to allow for easy access for resetting tripped breakers or for emergency shut-off. Regular inspection and maintenance by qualified electricians are recommended to ensure its safe and efficient operation.
