Circuit Breaker: What It Is, How It Works, and Types

Circuit Breaker

Circuit breakers play an important role in protecting your business from dangerous electrical hazards. But do you know what they are and how they work? Boyes Electric is the right place if you need circuit breaker repair in Oakland. In this blog, we will discuss some basics about circuit breakers and their types. Let’s explore more below.


Understanding Some Crucial Aspects of Circuit Breaker




Circuit Breaker is the most important device responsible for the overall safety of any property. It regulates the flow of electricity during a power outage, storm, or other related situations. These switches are installed within the breaker box of your home and protect your electrical system from overheating, catching fire, etc. For example, if the current flow becomes too strong, the circuit breaker will automatically turn off the switch to interrupt and protect from causing serious damage. 


How does a circuit breaker work?


A circuit breaker has sensors to detect the amperage of an electric current. Sometimes, the build-up of current becomes too strong for the circuit, causing overload issues. A sudden rise in electric current within a short interval of time is known as overcurrent. 


This is when the circuit breaker comes into the picture as it disrupts the current by shutting off automatically. The circuit wiring will overheat without circuit breakers, this will result in melted insulation. This could end up causing an electrical fire. This is why installing circuit breakers is crucial for fire safety for all buildings. You must also hire a professionally skilled electrician for circuit breaker repair


Types of Circuit Breakers


  1. Standard Circuit Breakers


Standard circuit breakers, commonly found in residential properties across the USA, are designed to protect against overcurrents and short circuits. These breakers come in various ampere ratings, making them suitable for different household applications. Standard breakers are typically installed in electrical panels and are easily replaceable, providing a cost-effective solution for protecting circuits.


  1. Ground Fault Circuit Interrupters (GFCIs)


GFCIs are specifically engineered to prevent electrical shocks and protect against ground faults. GFCIs are mandatory in areas where water and electricity may come into contact, such as kitchens, bathrooms, and outdoor outlets. These innovative breakers constantly monitor the electrical current flowing through a circuit and quickly interrupt it if a ground fault is detected, reducing the risk of electric shock.


  1. AFCI Circuit Breakers


Arc Fault Circuit Interrupters (AFCIs) are designed to detect and mitigate the risk of electrical fires caused by arcing faults. Arcing occurs when electricity jumps between conductors, potentially leading to overheating and fire. AFCI breakers are a crucial addition to modern homes, as they provide an extra layer of protection against fire hazards in bedrooms, living rooms, and other living spaces.


  1. Dual-Function AFCI/GFCI Circuit Breakers


To streamline electrical safety measures, dual-function circuit breakers combine the features of AFCIs and GFCIs in a single unit. This makes them versatile and efficient in protecting against both arc faults and ground faults, making them an ideal choice for various rooms in a residential setting. Homeowners can enhance safety by incorporating dual-function AFCI/GFCI breakers into their electrical panels.


  1. Miniature Circuit Breakers (MCBs)


MCBs, also known as Mini Breakers, are commonly used in residential and commercial settings. These compact breakers offer efficient protection against overcurrents and short circuits. With their smaller size, MCBs are a space-saving option for electrical panels, ensuring that homeowners can optimize their electrical layouts without compromising on safety.
