How to Choose the Right Circuit Breaker for Residential or Industrial Use

In order to protect your residential electric panels and high load industrial systems, you must choose right circuit breaker that offers the best performance and code compliance. No matter which electric system you use, a circuit breaker is one of the most essential safety devices that can protect you against short circuits and electricity overloads. Whether you are a homeowner or a facilitator, this guide will cover everything that you need to know in order to pick the right breaker for your applications. 

1-Understanding What A Circuit Breaker Does And It Works 

Circuit breakers are electrical switches designed to protect electrical circuits from damage in events like short circuits and electricity overloads. What happens is that the breaker interrupts the flow of electricity immediately when a fault is detected. It’s one of the most crucial electric components used by homeowners in residences, commercial and industrial facilities. 

2-Difference Between Industrial Vs Residential Circuit Breakers 

Whether you are looking for a breaker for home use or industrial use, you should first understand the difference between the two types in order to make a more informed decision. 

3- Types Of Circuit Breakers

If you want to choose right circuit breaker, it’s important to first understand the different types and what they are used for; 

MCBs-Miniature Circuit Breakers:

A miniature circuit breaker is mainly used in residential properties and for light commercial applications. Such breakers come with ratings up to 100A and their trip curves include B, C and D type. 

MCCBs-Molded Case Circuit Breakers:

A molded case circuit breaker is best suitable for commercial and industrial applications. Their ratings can range between 100A to 2500A and their main advantage is that they possess high breaking capacities with adjustable trip settings. 

AFCIs-Arc Fault Circuit Interrupters:

The AFCI breakers specialize in detecting arc faults that are usually the cause behind electrical fires. These breakers are typically used in bedrooms and living areas.

GFCIs-Ground Fault Circuit Interrupters:

These are the best industrial circuit breakers that provide protection against electric shock by detecting ground faults immediately. Not just for industrial purposes, in fact, these breakers are also used in other wet residential areas including kitchens and bathrooms. 

4-Key Considerations When Buying A Circuit Breaker

Whether you are looking for commercial breaker types or residential ones, there are some important factors that you must consider; 

• Your Load Requirement: You should first calculate the total load of your applications. For example, in case of residences, you’d need 15A to 20A breakers for lighting and other outlets. In case of industrial or commercial use, you first need to analyze your equipment and calculate your peak load to make a more informed decision. 

• Voltage Rating: Before buying a circuit breaker, ensure that it’s compatible with the system’s voltage. 

• Interrupting Capacity: You should always choose the breaker that comes with the maximum interrupting capacity especially considering your applications and your overall electrical system. 

• Enclosure Type And Environment: Check the NEMA and IP ratings to determine whether the breaker is suitable for you or not. Also, if you want to protect your electrical systems in a harsh environment with high temperatures etc then make sure to choose a waterproof and explosion proof breaker. 

5-Consider The Brand And Its Quality 

There are hundreds of different circuit breaker brands available in the market but not all of them are worth your hard-earned money. Choosing the right breaker isn’t just important to get the best value for your money, in fact, it’s necessary for your safety and protection as well. Events like short circuits and overloads can start fires which are extremely dangerous. To ensure that you never fall victim to such incidents, you should do your due diligence and opt for a reputable brand that offers the best and the most reliable circuit breakers. 

• For residential use you can opt for Eaton, Siemens, Leviton and Square D. 

• For industrial use, try ABB, GE, Siemens or Mitsubishi
  

Overall Verdict 

Without a circuit breaker, your residence or your industrial facility isn’t safe. Short circuits and electricity overloads are sometimes unpredictable and if not treated on time, they can wreak havoc on your property. To have some peace of mind and to ensure that your electrical system is protected, you need to invest in a reliable circuit breaker that not only performs well but is durable too. You should also perform a complete evaluation of your system’s requirements to end up with the right circuit breaker for your applications!
