History ELCBs were mainly used on TT earthing systems. Nowadays‚ ELCBs have been mostly replaced by residual-current devices (RCDs). However many ELCBs are still in use. Early ELCBs responded to sine wave fault currents‚ but not to rectified fault current. Over time‚ filtering against nuisance trips has also
