ELCB:-An ELCB is a specialised type of latching relay that
has a building's incoming mains power connected through its
switching contacts so that the ELCB disconnects the power
in an earth leakage (unsafe) condition.The ELCB detects
fault currents passing from live (hot) to the earth
(ground) wire within the installation it protects. If
sufficient voltage appears across the ELCB's sense coil, it
will switch off the power, and remain off until manually
reset. An ELCB however, does not sense fault currents
passing from live to any other earthed body.
RCCB:-A residual current device (RCD), or residual current
circuit breaker (RCCB), is an electrical wiring device that
disconnects a circuit whenever it detects that the electric
current is not balanced between the phase ("hot") conductor
and the neutral conductor. Such an imbalance is sometimes
caused by current leakage through the body of a person who
is grounded and accidentally touching the energized part of
the circuit. A lethal shock can result from these
conditions; RCDs are designed to disconnect quickly enough
to mitigate the harm caused by such shocks.
