What is a Circuit Breaker?

A Circuit Breaker is often confused with a safety switch. However, they are not the same device. A Safety Switch is designed to protect people from electrical shock. A safety switch will usually only cut off one affected area. 

An electrical circuit breaker, on the other hand, is manufactured to protect your home. Designed to safeguard the circuitry of your whole house, a circuit breaker is a switching device that interrupts any abnormal electrical current. 

In interrupting this faulty current, it can protect your entire electrical system from potential damage, including overheating and fires caused by power surges. 

What Does a Circuit Breaker Do? 

A circuit breaker is designed to ‘trip’ when a predetermined amperage loads. If a specific limit is reached anywhere in your home’s circuit, the breaker will trip and prevent the current flow, in turn protecting your entire circuit from damage. 

Common reasons a circuit breaker may trip include: 

Overloaded Circuits

When you are perhaps running too many appliances at once and overloading your switchboard. 

Short Circuits

This usually occurs if there is a significant wiring issue or an appliance is damaged. 

Arc Faults

This occurs when there are irregular power fluctuations, which can cause sparking. 

Ground Faults

When a live wire makes contact with a material that it shouldn’t, e.g. water. In these cases, there is a very high risk of electrical shock.

What Are The Different Types of Circuit Breakers?

There are many types and sizes of circuit breakers, and what you will need for your home may vary depending on the size of your circuit. 

Standard Circuit Breakers

Comes in two varieties, single-pole and double-pole circuit breakers. Single-Pole circuit breakers are the most common in domestic settings and will protect one energized wire. 

Double-pole Circuit Breakers

Designed for a shared trip mechanism and will protect two wires. 

GFCI Circuit Breakers or Ground Fault Circuit Interrupter Circuit Breakers

Designed to monitor overloaded currents. These are not suitable for continuously running appliances, such as refrigerators. 

AFCI Circuit Breakers, or Arc Fault Circuit Breakers

Specifically designed to stop electrical fires that would be caused by inadvertent electrical discharge. These kinds are usually installed alongside your standard breakers. 

 When choosing the right circuit breaker for your system, we recommend consulting with an electrical expert, like Dave Fenech.
