RCCB advantages

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.
