An ELCB is electric breaker device switch which saves you electric shock from any device. It detects the unusual path of earth leakage and immediately switches off the circuit to prevent human electric shock or even loss of life. ELCB was developed to detect human shock however it had too many disdvantages so RCCB was developed as an advance model of ELCB.
For household usage RCCB is nearly perfect as it basically monitors the current values of phase and neutral flowing through it and breaks the circuit if it’s unusual. ELCB is also RCD Residual Current Device so don’t worry if the RCCB you brought from market has RCD or elcb written on it.
ELCB/RCCB also helps in detecting the fault in wiring or appliances of the house. Its a must for a house with children atleast. Electricity board in country don’t give new connection without the installation of ELCB/RCCB/RCD in the house.
30mA , 60mA and 100mA written on RCCB / RCD /ELCB is sensitivity. Better ask your house electrician before buying sensitivity factor as 30mA can cause it to trip on even minor hiccups in house which can become pita for electrician to detect.
