WEBMar 30, 2021 · 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 to protect equipment, especially against fire. The earth fault currents that operate an rcd can range from 5mA up to many amperes.
