what is difference between RCB,RCCB &RCBO?

Answer Posted / tushar kanti saha

RESIDUAL CIRCUIT BREAKER(RCB) IS SIMILAR TO RESIDUAL CURRENT CIRCUIT BREAKER(RCCB).
RCCB- IT PROTECTS THE CIRCUIT WITHOUT AN OVERLOAD.
BUT RESIDUAL CURRENT CIRCUIT BREAKER OVERLOAD(RCBO)- IT PROTECTS THE CIRCUIT WITH AN OVERLOAD, MAINLY WHERE WE NEED MORE EARTH LEAKAGE PROTECTION AT THERE RCBO IS USED.
