Residual current circuit breaker(RCCB) will trip if
algebric sum of current is not be zero.

Answer / kulvinder singh, nit kurukshet

ELCB is used tirip the breaker when there is any leakage
of live current to the earth point.

RCCB-it detects the electric current is not balanced
between the energised conductor and return neutral
conductor.Such an imbalance is also caused if any human
body comes in contact with live conductor.
