WebIn electrical circuits, current returns to its source. A current-based ground-fault relay may look for ground-fault current in one of two ways: 1.) Zero sequence. Here, the relay looks at the phase conductors to ensure that all current coming from the source returns on those same conductors. If some of the current is returning to the source ... WebWorking principle of RCCB (Residual Current Circuit Breaker ): Under Normal condition, the Total current flows in the phase wire is equal to neutral wire. i.e consider now you have 10Amps is phase side means the same current 10 Amps flow in the neutral side also.
