power trip troubleshooting

Power outages are common in Singapore, especially during the rainy season. If you're traveling to Singapore and experiencing a power outage, don't worry - we're here to help! We will go through some of the most common electrical problems in Singapore and provide tips on how to solve them.

A power trip is a typical issue that Singaporeans encounter. This may be highly inconvenient since it can cause a power outage, which would prevent the use of electrical equipment. Some households have resolved a power trip by getting their circuit breakers serviced. Others, on the other hand, might choose to do their electrical repairs. If you're in this group, here are some tips for dealing with a power trip on your own

Reasons Why Circuit Breaker Keeps Tripping

Overloaded Electric Circuit

One of the main reasons for a power trip is that the electrical circuit is overloaded beyond the stated limit. When the current in an electric circuit reaches or exceeds its rated capacity, it can be damaged or cause a fire danger. A circuit trip occurs to prevent a real fire from occurring.

The supply may trip if you connect multiple electrical equipment to a power source. In particular, malfunctioning appliances may use more electricity, increasing the overall current flow and causing the circuit breaker to trip.

Short Circuit

A short circuit, for example, might cause an HDB circuit breaker to trip. One easy method to discover this is by sniffing the area for burning odors. When a hot (black) comes into contact with a neutral (white) wire usually causes a short circuit. A surge in electrical current supply can also occur due to faulty wiring coming into touch with one another in the presence of damaged insulation. When appliances or lights connected via faulty wiring are used on an outlet, they may create a short circuit.

Ground Fault

A ground fault can also cause a power trip. When the circuit breaker's hot wire comes into touch with the ground, the resistance is reduced, causing more current flow. A hot wire (black) that makes contact with a metallic surface can also trigger a circuit breaker to trip.

Householders risk experiencing a deadly circuit when they do not follow general electricity safety recommendations. Furthermore, it can cause a severe accident, such as an electrical shock from switches or sockets.

Steps to Take to Resolve a Power Trip

Most Singapore houses have a distribution box or panel with circuit breakers as their electricity supply. These are unique switches that trip automatically to protect against over currents. They may cause your light installations to go out of operation. Take note of the following procedures to restore power to your home:

Identify The Faulty Appliance

When a faulty device is switched on, an HDB circuit breaker usually trips. You must discover which appliance triggered the trip to fix it. Any equipment or product that uses a lot of power will likely be the source. If that's not the case, look for an appliance with damaged electrical wiring.

Locate Your Circuit Breaker

The electrical circuit breakers placed in homes are generally installed in a grey metal box or panel. This is usually positioned in the utility room and is almost always wall-mounted like house light switches. Each electric circuit at home includes at least one main double pole circuit breaker, a little circuit breaker (MCB), and a few single-pole mini circuit breakers. In addition, licensed electricians sort circuit breakers into rooms where they're put, with each group having its identifier to indicate the location of the electric circuit.

Usually, a brief power outage is caused by a little overflow of current on the single pole MCB. The main MCB may also be tripped if the current surge is significant. Remember that the tripped circuit breaker is often in the off position after the occurrence.

Switch Off All Appliances

After finding the faulty equipment, turn off all other appliances on the same circuit. That way, no devices will draw power from the main supply when you switch on the circuit breaker on your distribution board. Furthermore, turning off all of your appliances can assist reduce current flow.

Turn On Your Circuit Breaker

If your circuit breaker keeps going off, it might be because of a problem with the electrical wiring or grounding. Turn off all electrical equipment and turn on the circuit breaker to see if that fixes the problem. In that case, an electrical wiring repair or replacement may be required. If your circuit breaker does not trip, gradually turn on one appliance after another and see which sparks or cracks. Remove the faulty device from the electric circuit and have it repaired or replaced once you've identified it as the source of the problem.

If neither your circuit breaker nor your appliance starts sparking or burning once you have switched on the latter, it's possible that an overload caused the power trip you were attempting to avert. Switch off or unplug as many devices at once as desired or plug them into electrical outlets with a lower voltage rate in this situation.
