Circuit Breaker 101: Understanding Why It Keeps Tripping

Short circuits, overloads, and ground faults can all trip circuit breakers. While it may be possible for you to repair your electrical system and circuit breakers, this is not the ideal step. Remember, electrical issues are always best addressed by professionals. This is because they could be dangerous to any homeowner.

Today, we are here to spread knowledge about short circuits, overloads, and circuits. The following information can help you address electrical system and circuit breaker concerns. Read on to learn more.

Explaining a Circuit Overload

When a cable or circuit draws more current than it can handle, it is overloaded. This could be caused by loose or rusty connections or cables.

It is possible to overload a circuit with an excessive number of plugs. Assume your microwave frequently tripped the circuit breaker. The circuit for your microwave may be shared with larger appliances. It is unable to power a microwave. Consider a circuit that has been overloaded. You can unplug something and utilise another power source.

If circuit overloads persist, unhook everything before resetting the fuse box. This addresses the problem. After resetting the fuse box, you can test each appliance to see which one caused the overload.

A new power supply may be necessary to support the additional amperage.

Installing outlets for large appliances like dishwashers and air conditioners saves electricity.

The Short Circuit

A short circuit occurs when a hot wire meets a neutral wire, overloading the circuit. Short circuits should trip breakers or burst fuses. It catches fire, bursts, and generates smoke. Other problems include loose connections, slipped or chewed wires, and bitten wires. A short circuit could be caused by a malfunctioning switch or outlet.

It is not recommended to investigate the short circuit. Only qualified electricians are permitted to identify and repair electrical problems in Queensland, according to the state’s electrical laws.

High current temperatures can generate flames due to short circuits. Seek professional help if your home has problems, especially if they are not obvious.

The Ground Fault

Ground faults can occur when live or hot cables come into contact with the ground wire or a grounded junction box section. The ground wire is green, the neutral wire is white, and the live wire is black. A hot-to-ground connection has the potential to trip the circuit breaker.

To prevent electrical shocks and fires, ground fault circuit interrupters should be placed. These include kitchens, bathrooms, and outdoor areas. Ground failures can occur when damaged or malfunctioning equipment exposes live electrical components to accidental contact.

When repairing or diagnosing electrical problems in the home, exercise caution. Never attempt to repair or check harmful items. Unless you are a trained electrician, do not attempt to repair electrical equipment or cords. A professional should also be the one to evaluate wet electrical equipment before turning it on.

A short circuit’s high voltage can heat and burn the wire. Ground faults can cause significant shocks, especially in those with minimal resistance.

This is especially true in wet situations like bathrooms, kitchens, and the outdoors. Assume a ground fault exists. To protect yourself and your family from harm, address the problem as soon as possible and contact a professional.

Identifying a Faulty Circuit Breaker

Circuit breakers, like other household appliances, can fail. Fault circuit breakers are usually identified when there is a non-resettable circuit breaker, when the fuse is tripping on a regular basis, if the electrical box has caught fire, and if the circuit breakers have been damaged with scorch marks. A smoke-emitting device or fixture could also be shorted or overloaded. 

If you haven’t maintained your electrical panel or circuit breakers in the last ten years, they could be worn out. Your circuit breakers may need to be replaced. As such, contact an electrician if your circuit breaker continues to trip. An electrician can troubleshoot ground and short circuit issues.


Expert assistance is required for your home’s electrical system. If your electrical system is not working properly, contact a professional. This way, you will be guided and even be educated by an experienced electrician. You can also take this as an excellent opportunity to perform a complete house inspection safely.
