Having an RCCB installed doesn’t always mean your entire home is safe. Especially in older HDB flats built before July 1985, some parts of the home may still rely on outdated wiring that isn’t protected by the RCCB. Read more to avoid RCCB risks in Singapore now.
Understanding Split Wiring Systems in Older HDB Flats
In many flats upgraded through HDB’s Main Upgrading Programme (MUP), electricians installed a new electrical wiring system alongside the existing one. However, they often connected RCCBs only to the newer system.
This means older parts of your home—like the water heater circuit—may still run on unprotected wiring. The fatal accident in Jurong, reported by CNA, warns all homeowners about the risks.
Why Licensed Electrical Workers Are Essential
Only a Licensed Electrical Worker (LEW) in Singapore can confirm whether your entire electrical system is protected. LEWs inspect both old and new circuits and ensure RCCBs are correctly installed to cover all wiring systems.
Meeting the EMA RCCB Regulation by 2025
The Energy Market Authority (EMA) has made it mandatory for all homes built before July 1985 to install or upgrade RCCBs by 1 July 2025. A two-year grace period began in July 2023, giving homeowners time to comply.
Conclusion
Don’t assume your RCCB is doing its job—verify that your entire electrical system is protected, especially if your flat was built before 1985 and underwent partial upgrades.
Protect your family. Contact a certified electrician or LEW today to perform a full RCCB inspection and avoid RCCB risks in Singapore before it’s too late.
