Welcome to EMA’s new website. We would love to get your valuable feedback through FormSG.
Follow these tips to keep you and your family safe from electrical accidents.
Engage Only Licensed Electrical Workers
Engage only licensed electrical workers to carry out any electrical installation, maintenance and repair work. These include new wiring, rewiring and extensions which also have to be tested by an authorised officer from SP Services Ltd before supply can be turned on.
Watch this episode of Channel NewsAsia’s Talking Point on the electrical safety of water heater installation for your home.
Keep Electricity and Water Apart
Use electrical appliances near water or with wet hands, or
Touch an open electrical outlet or electrical switch with wet hands.
Do Not Overload Power Points
Overloading power points is dangerous as it may lead to over-heating and start a fire. So do not ’piggy-back’ multiple plugs into one socket by using double adaptors.
It is also important to not use cracked or broken power points/ extension socket outlets. Replace damaged power points/ sockets immediately with the help of a licensed electrical worker to prevent current leakage.
Check the Earth Wire
An unearthed plug can cause electric shock when there is a short circuit in an appliance. Take the following precautions with electrical cords and cables:
Replace electrical cords with broken or frayed insulation. Do not join cut or frayed electrical cords together with insulation tape as this may peel off after some time, leaving wires exposed. Replace the cord with a new one instead.
Do not run wires around sharp edges. Running wires around sharp edges can cut their insulation and expose live wires which are dangerous.
Keep electrical cables tidy and organised. Hide or keep electrical cables out of the way to create a safer environment and prevent potential incidents of strangulation or electrocution.
Store electrical cords securely. When electrical appliances are not in use, switch them off and store the electrical cord carefully to avoid damage.
Check Your Residual Current Circuit Breaker Regularly
The RCCB is an electrical safety device that cuts off electricity supply immediately upon the detection of current leakages that may lead to an electric shock. Leakages can be caused by factors such as ageing or exposed wires, faulty electrical appliances, and damaged insulation.
Since 1 July 2023, all residential premises are required to have an Residual Current Circuit Breaker (RCCB) installed.
For your safety, test your RCCB once a month to check that it is in good working condition. Visit the Educational Materials section to find out how you should test your RCCB.
Frequently Asked Questions
The Residual Current Circuit Breaker (RCCB) or commonly known as the circuit breaker is an electrical safety device that cuts off the electricity supply immediately upon detecting leakages that may result in an electric shock. Current leakages can be caused by factors such as ageing or exposed wires, faulty electrical appliances, and damaged insulation.
The RCCB is usually located in the distribution board (also known as DB box) or circuit breaker box in your home. It can be identified as a switch with a ‘Test’ button. For HDB residents who are unable to locate your RCCB, please contact your Branch Service Line at 1800-225-5432.
Yes, if you do not already have an Earth Leakage Circuit Breaker (ELCB) or Residual Current Circuit Breaker (RCCB) installed in your home. To enhance electrical safety in all households, all residential premises without a circuit breaker will be required to install an RCCB.
All homeowners will be given a grace period of two years, till 1 July 2025 to do so. 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.
You can perform the following 3-step test to ensure your Earth Leakage Circuit Breaker (ELCB) or Residual Current Circuit Breaker (RCCB) is working and protects all electrical circuits in your home.
Test the ELCB or RCCB by pressing the ‘Test’ button. The ELCB or RCCB switch will flip down and cut off all power supply in your home. If the ELCB or RCCB switch does not flip down, it is faulty. Homeowners should contact a Licensed Electrical Worker for assistance immediately.
Test all light switches and power sockets in every room. The ELCB or RCCB is working if lights and power sockets do not turn on when the circuit breaker switch is flipped down. If any light or power socket continues to work when the circuit breaker switch is flipped down, the house is not fully protected by the circuit breaker. Homeowners should contact a Licensed Electrical Worker for assistance immediately.
Flip up ELCB or RCCB switch to restore power supply. Switch on lights and appliances that you need.
For a detailed step-by-step guide, please visit our RCCB Safety. You are advised to test your ELCB or RCCB once a month to check that it is in good working condition.
All homeowners can engage a Licensed Electrical Worker to install an RCCB if necessary. It is recommended to contact a few LEWs to perform price comparisons before engaging one. 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.
