Maybe your understading of the elcb/ rccb is not true.Any load
consumed current is shared among the phases or and
newtral.that means what ever current that flows through the
elcb must flow out,there can be a difference only when there
is a loss, which means some of this current that had flowed
through are flowing out a different route,(leakage)if this
difference exceeds the trashold of the elcb/rccb than it
trips.
