RCCB stands for Residual current circuit breaker, it is nothing but quickly breaks an electrical circuit to prevent serious harm from an ongoing electric shock. Let us have a deep insight into the advantages and disadvantages given by RCCB.
Advantages of RCCB:
- The main purpose of RCCB is to protect the human from the residual current.
- It is used to protect against the earth's fault as well as electrical shock.
- It automatically disconnects the circuit when the rated sensitivity is exceeded.
- It offers protection against voltage fluctuations as it includes a filtering device that guards against transient voltage levels.
- It offers the possibility of dual termination both for cable and busbar connection.
Disadvantages of RCCCB:
- RCCB does not have short circuit protection.
- Nuisance tripping of RCCB.
- RCD doesn't offer protection against current overloads.
- This circuit breaker will not protect against a socket outlet being wired with its live and neutral terminals the wrong way round.
- RCCB is a higher cost.
- This circuit breaker will not protect against live neutral shocks, because of the current in life and neutral in balance.
- RCCB does not protect from the overheating that strike if conductors are not properly screwed into terminals.
- RCCB does not guarantee to operate if none standard waveform is generated by a load. It is mainly because RCCB is designed to operate on a normal supply waveform.
