husholdningsspændinger

Husholdningsspændinger refer to the electrical voltage supplied to residential buildings. In most of Europe, including Norway, the standard household voltage is 230 volts (V) at a frequency of 50 hertz (Hz). This is a significant change from earlier standards of 220V and 240V, which were gradually harmonized across Europe. In contrast, North America typically uses 120V at 60Hz. This difference in voltage and frequency is important to consider when using electrical appliances imported from different regions, as incompatible voltages can damage devices or pose safety risks.

The electricity is delivered to homes via a power grid and then distributed within the house through a system of wires, circuit breakers, and outlets. Household electrical systems are designed with safety features like grounding and circuit breakers to prevent overloads and electrical fires. Understanding household voltage is crucial for safely operating appliances, performing electrical maintenance, and choosing appropriate extension cords and power strips. It's always recommended to consult with a qualified electrician for any electrical work beyond simple appliance connections.
