The Antarctic Circumpolar Current (ACC), the strongest ocean current on Earth, is rapidly weakening due to the accelerating ...

The residual current device (RCD) is used to detect earth fault currents and to interrupt supply if an earth current flows. The main application is to prevent electrocution but RCDs can also be used ...
