Answer Posted / s.saravanan
--> RCCB is better than ELCB...
--> ELCBs senses the fault current flowing through the
ground only...
--> But fault currents can still flow through other
conducting elements such as an adjacent conductor which is
unenergized and whose insulation is incidently got damaged
and coming in contact with the conductor which is live and
its insulation also got damaged...
--> In this instant fault current flowing through the
ground is nil and the ELCB fails to sense it...
--> But RCCB works in core balancing technique and
therefore any difference in current flowing in through a
Line conductor and current flowing out of the neutral
conductor during faulty conditions will be sensed by the
detector coil and trips the circuit...
--> Let us widen our knowledge over the fault currents
since fault current doesn't flow only through ground but
also in some other unplanned paths...
--> Hope my answer will be more convincing to all...
--> All the best...
--> Have a nice day forever...
