Power Trip in Singapore: A Comprehensive Guide on How to Reset and Restore Electricity

by Earl S

Encountering a power trip is a common electrical problem faced by homeowners in Singapore, leading to power failures and the inability to use electrical appliances. While some homeowners prefer to opt for professional circuit breaker servicing, others may choose to tackle the electrical repairs themselves. For those in the latter group, here are several methods to resolve a power trip on your own.


Steps To Take To Resolve A Power Trip

In Singapore, most homes have their electric supply directed through a distribution box or panel of circuit breakers. These specialized switches are designed to trip automatically and prevent electrical overload, but they can also cause power loss to your light fixtures. To restore electricity to your home, follow these steps:

Identify The Faulty Appliance

Typically, an HDB circuit breaker trips when a faulty appliance is switched on. To resolve the power trip, you must pinpoint the specific appliance responsible for the issue. High-energy-consuming devices or products are often the main culprits, while appliances with damaged electrical wiring can also trigger a trip.

Locate Your Circuit Breaker


The circuit breakers are usually housed in a gray metal box or panel, often found in the utility room and mounted on the wall, resembling light switches in your home. Within this panel, you’ll typically find a main double pole circuit breaker, a mini circuit breaker (MCB), and several single pole mini circuit breakers for each electric circuit in your home. Electricians categorize circuit breakers based on the room they serve, with labels indicating the location of each electric circuit. After a power trip, the tripped circuit breaker is usually in the “off” position. 

Switch Off All Appliances


Once you have identified the faulty appliance, switch it off along with all other appliances. This ensures that no appliances draw power from the main supply when you turn on the circuit breaker on your distribution board. Additionally, disabling all appliances helps reduce the flow of current.

Turn On Your Circuit Breaker


After ensuring that all appliances are switched off, turn on the circuit breaker. If it continues to trip, there may be an issue with the electrical wiring or earthing, requiring repair or replacement. If the circuit breaker doesn’t trip, gradually switch on your appliances and observe if any of them cause sparks or popping sounds. Once you identify the defective appliance, disconnect it from the electric circuit and have it repaired or replaced.

If neither the circuit breaker nor the appliances cause any issues when switched on, it’s possible that the power trip was due to an overload. In this case, reduce the number of devices used simultaneously or plug them into electrical outlets with a lower voltage rating. Additionally, it would be essential to know how to fix a tripping circuit breaker at home.


Important Safety Precautions To Take When Resolving A Power Trip

To ensure your safety while resolving a power trip, take the following precautions:

  • Avoid wet hands or wet floors, as water is a conductor of electricity.
  • Wear appropriate safety gear, such as insulating footwear.
  • Disable your electric supply to prevent contact with live wires.

Following these general electrical safety tips is crucial to prevent injuries and protect your electrical devices and appliances. However, in the situation whereby you are unable to resolve a power trip, it is recommended to consult an electrician.

It is crucial to emphasize the importance of identifying the faulty appliance that caused the trip and locating the circuit breaker panel. It is recommended to switch off all appliances, including the faulty ones, before turning on the circuit breaker to restore power. If the circuit breaker continues to trip, there may be an issue with the electrical wiring or earthing that requires professional repair. Reducing the number of devices used simultaneously or using outlets with a lower voltage rating if the power trip was caused by an overload is also ideal. Overall, by following these steps and safety measures, individuals can effectively resolve power trips and ensure their safety.
