Are Circuit Breakers Important?

Are Circuit Breakers Important?: In the general aspects of the electrical safety of homes and buildings, circuit breakers have a significant role to play. But where do they stand vis-à-vis the prominent subjects? Understanding their function and importance might help to draw attention to the fact that circuit breakers are an essential element that has to be in any electrical system to minimize the risk of a number of dangers.

Circuit Breaker: What is it? 

Definition and Function 

A circuit breaker is an electric switch that is designed to protect any electrical circuit from being damaged due to excessive current. Its primary purpose is actually to break the flow in the current path as soon as a fault is introduced. This interruption helps avoid any harm that might be caused to the electric system and minimizes the chances of electrical fires. 

Types of Circuit Breakers 

There are several types of circuit breakers, each suited to different applications:

  • Standard Circuit Breakers: Applied in residential as well as commercial buildings, they safeguard the circuits from overloading and short circuits. 
  • Ground Fault Circuit Interrupters (GFCIs): Prevent electric shock by cutting the circuit when a difference in current is sensed.
  • Arc Fault Circuit Interrupters (AFCIs): To detect and interrupt arcing faults that pose the risk of developing into fire risks. 

Why do we have circuit breakers? 

Preventing Electrical Fires 

Circuit breakers are used mainly for protecting electrical appliances and people’s lives from electrical fires. Electrical fires occur because the wiring or some devices ignite due to the flow of excess current. Circuit breakers are able to sense such hazardous situations and switch off the power, thus halting such a fire in its tracks. 

Protecting Appliances and Devices

Circuit breakers also safeguard appliances and other electronic devices from damage. Sometimes one of these circuits can get overloaded and cause undesirable current to flow through the circuit, which may be damaging to the tiny parts of an electronic device. Circuit breakers also keep your appliances and devices working for a longer time since they are protected from being damaged during the mentioned events by denying power supply. 

Ensuring Personal Safety 

Accidents that may happen due to electrical problems can be a threat to the lives of people vulnerable to electric shocks and burns. GFCIs are a kind of circuit breaker intended for the protection of humans from electric shocks, especially in zones that are more dangerous, such as the bathroom or a kitchen. Since they interrupt power immediately when there is a ground fault, GFCIs help prevent deadly incidents from occurring. 

How Circuit Breakers Work 

Mechanism of Action 

Circuit breakers work on a very basic and efficient principle. To connect the circuit, they have internal contacts. When the electrical current is going smoothly, these contacts remain in the closed position. However, when the current rises over a certain level, the mentioned contacts open, and the circuit as well as the current flow are interrupted. 

Resettable Safety Device 

While fuses are consumable items that must be replaced when their operative mechanism is activated or blows, circuit breakers are not disposed of as they can be reset. Due to this, resettable voltages are preferable as they are easier to employ and cost-effective in the long haul. Hence, after fluctuating because of an overload or short circuit, the breaker can be reset to bring back the current. 

Together with great usage, there are other indications that you may need the appropriate care of your circuit breaker, which include: 

Frequent Tripping 

If a circuit breaker goes off often, then this could mean that there is an issue; it could be a load issue, a short issue, a breaker issue. Tripping should not be a normal occurrence, as it may be a sign of a major safety hazard in properties. 

Physical Altercation or Bang/Burning Odor 

Signs like black marks on the breaker’s panel or even a burning smell around the circuit breaker indicators should alert you. Such problems can only be dealt with by a professional, with the fear of electrical fires or more damages occurring. 

Age and Wear 

Sometimes, they get rusty and therefore cannot be effective anymore; this is the time they need to be replaced or refurbished. If your circuit breakers are faulty and antique, then you might need the services of an electrician, who should help assess the circuit breakers. 


These circuit breakers are very important, especially as far as electrical safety is concerned, in any given setting. They guard against electrical fires, safeguard apparel and devices, and help secure the lives of people by interrupting hazardous circuit currents. They play an important role as far as electrical safety is concerned; therefore, it is always important to understand whether they are present or not, and most importantly, whether they are in good working condition or not. It is essential to remember that a proper electrical system needs to be serviced from time to time, and when there are indications of problems, they should be fixed on an urgent basis.
