Answer Posted / vinod
When two ELCB in prallel sending current & return current
of each ELCB will not be equal (example one ELCB is
sending 4 amps to the load but due parallel the retun
current from the load to the same ELCB may not be 4 amps,
retun path through other ELCB treat as a earth fault, so
one ELCB will trip.
