ELCB
1. Full of ELCB is Earth Leakage Circuit Breaker.
2. ELCB is a voltage-operated device and having an old name and old technology.
3. ELCB is only used for detecting earth fault which is flowing back by the main earth wire.
4. ELCB is connected To phase wire, Neutral wire, and also with earth wire.
5. In case of ELCB earth connection is required.
6. Type of ELCB is AC= This used for alternating current, A= this is used for square wave, and B= This is used for direct current.
7. There is less nuisance tripping in case of ELCB.
8. ELCB is very costly.
9. Nowadays, ELCB is not recommended for use. Replace ELCB with RCCB.
10. Nowadays ELCB is not used in wiring work.
RCCB
1. Full form of RCCB Residual Current Transformer.
2. RCCB is a current operated Device with new technology.
3. RCCB will detect any type of Earth fault, so nowadays RCCB is used Instead of ELCB.
4. RCCB is only connected to the phase wire and neutral wire.
5. RCCB has not required any type of earth connection.
6.Type of RCCB is AC= this used for alternating current, A= this is used for Square wave, and B= This is used for Direct current.
7.Nuisance tripping in case of RCCB is very high.
8. Cost of RCCB is very less.
9. In all domestic or industrial wiring RCCB is mostly used.
10. Nowadays RCCB is the very safest device and mostly used in wiring work.RCCB having a rating of 30 ma, 100 ma, And 300 ma
