Difference between RCCB & ELCB

Question

Accepted Answer

RCCB is used to protect against earth faults, while ELCB is used to protect against earth leakage currents.

RCCB stands for Residual Current Circuit Breaker and protects against earth faults by detecting the difference in current flow between live and neutral wires.
ELCB stands for Earth Leakage Circuit Breaker and protects against earth leakage currents by detecting any current leakage to earth.
RCCB is more sensitive and can detect smaller current imbalances, while ELCB is less sensitive and mainly used for larger appliances.
RCCB is commonly used in residential and commercial buildings, while ELCB is commonly used in industrial settings.
Both RCCB and ELCB are important safety devices to prevent electric shocks and fires.
