hovedforbindelse

Hovedforbindelse is a Norwegian term meaning the main connection between a customer installation and a larger public network, and it is used across electrical, telecommunications, and other utility contexts. It designates the primary interface where service from a network operator enters a property. The concept is to provide a controlled, metered entry point and to define the boundary of responsibility between the network operator and the customer.

In electrical installations, the hovedforbindelse is typically located at the property boundary or at the service entrance. It includes the service conductors from the distribution network, the electric meter, and the main switching device (such as a main circuit breaker). In many standards, the utility is responsible for equipment up to the service point, while the customer is responsible for the installation beyond that point, including wiring, distribution panels, and local safety measures. The grounding system is often connected at or near this point as well.

In telecommunications and data networks, the hovedforbindelse marks the primary demarcation point between the provider’s network and the customer’s internal network. It defines where the provider’s responsibilities end and the customer’s network management begins, and it is commonly the point used for service provisioning and fault isolation.

Safety, reliability, and regulatory compliance are central to the hovedforbindelse. Installing or altering the main connection typically requires adherence to applicable electrical or building codes, permits, and inspections. Proper sizing, protection, metering accuracy, and clear responsibility boundaries are essential for safe operation and service continuity.
