RCCB advantages

RCB called as the 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 balanced.
  • 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 normal supply waveform.
