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.

Answer / karthick

pls to be check elcb current rating in case rating are
different. lower rating elcb got easily tripped. in case
elcb rating are same connecting load to be check

Answer / prashant

if loae is high then you connect two cb, if any one of cb
is trip then ohter cb is also trip. Due to high current.
because if any cb is trip then all current is flow through
the second cb.

Answer / arvind

when you are connecting two ELCB parallel then its mean the
voltage between these will be same but not the current, so
which ever ELCB is connected to higher current side is
getting trip if the current is flowing greater than the set
value.

Answer / purushotham

the ELCB's are connected in parllel, so the voltage in the
ckt is equal but current is diff. so if one coil trips the
ckt will works on second ELCB and total loading depends on
that second ELCB.
