jordfelsbrytarens
Jordfelsbrytarens, which translates to "residual current device" or RCD in English, is a crucial safety device in electrical installations. Its primary function is to protect individuals from electric shock by detecting imbalances in the electric current flowing through a circuit. An RCD works by monitoring the current flowing in the live conductor and the neutral conductor of a circuit. Under normal circumstances, these currents are equal. However, if a person or conductive object comes into contact with an energized part and a path to earth, some current will flow through that path instead of returning through the neutral conductor.
This imbalance, however small, is detected by the RCD. When the difference in current exceeds a predetermined
