IN THE CASE OF AN ELCB, IF THERE IS ANY UNSTABILITY BETWEEN PHASE AND NEUTRAL I

IN THE CASE OF AN ELCB, IF THERE IS ANY UNSTABILITY BETWEEN
PHASE AND NEUTRAL IT MAY TRIP. BUT MY QUESTION IS WHEN A
LOAD IS CONNECTED IN BETWEEN P AND N, THE LOAD CONSUMES SOME
POWER AND THERE IS A DIFFERENCE IN NEUTRAL WITH RESPECT TO
THE PHASE. THUS ACCORDING TO ME, THE ELCB WILL AUTOMATICALLY
OPERATES WHEN EVER THE LOAD CONSUMES-- I KNOW IT IS WRONG.
BUT THE SOLUTION IS?????????

IN THE CASE OF AN ELCB, IF THERE IS ANY UNSTABILITY BETWEEN PHASE AND NEUTRAL IT MAY TRIP. BUT MY Q..

Answer / pillay

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.
