ELCB= Earth Leakage circuit breaker
RCCB= Residual current circuit breaker

elcb looks for current flowing in the earh wire and is it
does not equate to the phase current , earth leakage is
detected an the CB trips.

rccb looks for the residual current ,by adding the phasor
current . upon any imbalance the CB trips on residual earth
fault.

Answer / velusamy

The ELCB works on the principle that the total amount of
current flowing thro the phase is returned thro neutral. if
not so , elcb trip the circuit.

For RCCB, i agree with ans 1 & 3

Answer / karthik

RCCB: detects current imbalance.but does not provide over
current protection.
ELCB: detects earth current directly rather than detecting
imbalance.

Answer / vinodh.t

ELCB= Earth Leakage circuit breaker
RCCB= Residual current circuit breaker
both are same..the objective of elcb is continuous
monitoring of insulation levels of electrical installation
and equipments and also detect any leakage current flow to
earth
