Mr. Mehdi, Do check the neutral of all circuits wether they
are connected to same ELCB group. If one neutral from one
group is connected to other group this problem will occur.
Even though all neutral is common at final point, each
neutral will have to pass through the ELCB in order to
monitor the return cuurent.
