I have an Earth Leakage Circuit Breaker (ELCB) in my home. Do I need to change it to a Residual Current Circuit Breaker (RCCB)?
If you have an Earth Leakage Circuit Breaker (ELCB) installed in your home, you do not need to change it to a Residual Current Circuit Breaker (RCCB). Both the ELCB and RCCB are electrical safety devices that cut off the electricity supply immediately upon detecting leakages that may result in an electric shock.
Homeowners with RCCBs or ELCBs are advised to test that their circuit breaker is in working condition using a 3-step test. This is to ensure that the circuit breaker is functional and protects all electrical circuits in the home.
If the circuit breaker is not working, homeowners can engage a Licensed Electrical Worker to replace the circuit breaker. HDB will be writing to the homeowners of 3-room and larger flat types, completed in and before 1985 without an RCCB, to share more information on the assistance programme for the installation of RCCB.
