what is the difference between elcb,rccb,mcb.

Answer Posted / prdp

The function of MCB is quite clear,it gives overload
protection and connected to the phases.
while RCCB & ELCB detects the leakage current flowing
to earth, they are connected to the neutral wire of the
supply and compare the sum of current through phases with
the current though nuetral. any mismatch will indicate the
presence of earth leakage current.
