Electrical safety at home isn't complicated, but it does require a bit of awareness. Here are ten practical habits every homeowner in Singapore should follow.
1. Don't overload sockets
Avoid daisy-chaining multiple extension cords or power strips into a single outlet, especially for high-draw appliances like air-conditioners, kettles and irons.
2. Check your RCCB/ELCB regularly
Your residual current device is your first line of defence against electric shock. Test it monthly using the built-in test button.
3. Keep water away from electrical points
Never operate switches or appliances with wet hands, and ensure bathroom/kitchen sockets are properly rated and positioned.
4. Replace damaged cords immediately
Frayed or cracked cables should never be taped over — replace them.
5. Use licensed electricians only
DIY electrical work is both risky and, for most fixed wiring, not legally permitted in Singapore.
6. Mind your DB box
Keep it accessible, correctly labelled, and never bypass a tripped breaker without finding the cause first.
7. Unplug unused appliances
This reduces both fire risk and standby power consumption.
8. Install smoke detectors
Early warning dramatically improves outcomes in the rare event of an electrical fire.
9. Schedule periodic inspections
Especially for older flats and commercial units, a professional check every few years catches problems before they escalate.
10. Know where your main switch is
In an emergency, every second counts — make sure everyone at home knows how to cut power quickly.
