If you have an ELCB in your home, you do not need to change it to a RCCB. Both the ELCB and RCCB are safety devices that cut off the electricity supply upon detecting electricity leakage in your home. It protects you and your family from electrical shocks or injury.

You are advised to test the circuit breaker regularly using the 3-step test to ensure that it is working properly and protects all electrical circuits in your home. If the circuit breaker is working properly, you do not need to replace it. If it is faulty, you can engage a Licensed Electrical Worker via www.go.gov.sg/rccb-lew to repair or replace it.
