Sikkerhedsswitchers

A sikkerhedsswitcher, often translated as safety switch or residual current device (RCD), is an electrical device designed to protect people from electric shock. It works by constantly monitoring the electric current flowing through a circuit. If it detects an imbalance, meaning more current is flowing out than returning, it assumes this difference is leaking through a person or other unintended path, and it rapidly cuts off the power. This fast-acting mechanism can prevent serious injury or fatality from electric shock.

These devices are commonly installed in homes, workplaces, and other environments where electrical safety is paramount. They are particularly important in areas where water is present, such as kitchens and bathrooms, as water significantly increases the risk of electrocution. A tripped sikkerhedsswitcher indicates a potential fault in the electrical system or an appliance. Resetting the switch is possible, but if it trips repeatedly, it suggests a persistent electrical problem that requires professional diagnosis and repair by a qualified electrician. Regular testing of the sikkerhedsswitcher is also recommended to ensure it remains functional and effective.
