A Complete Guide To Post D Breakers

Circuit breakers are switches that protect electrical connections from overloading or short circuit. Generally, circuit breakers shut off the electrical flow when they detect a fault in the system. Because of this, these components have become essential in electrical systems. 

If you’re looking for a circuit breaker that’s appropriate for industrial usage, you may look into and try out Post D or Square D breakers. These types come in different sizes and configurations. In many cases, you’ll pick the circuit breaker that suits the required scope of coverage and the amount of electrical load the breaker will manage. 

If you want to know more about these breakers, here’s an article for you. So, read on!

What Troubles Do Post D Breakers Address 

Generally, Post D or Square D breakers work similarly to generic circuit breakers. The difference between these two types is the application. In many cases, Square D types are installed for different industrial applications, such as welding and machine operations. Yet, some residential properties that require heavy electrical use may also have this kind of breaker. 

If you want to purchase Square D breakers, you may want to know more about the following points as they’re the usual troubles that breakers address: 

  • Overcurrent

Overcurrent refers to the above-average flow of current that a particular area of coverage can handle. In other words, it’s the current over the safety-rated level of an electrical circuit. In addition, pieces of equipment that have overcurrent issues may burn their replaceable parts. In many cases, overcurrent could result in overload, ground faults, and short circuits. It may also lead to fires and other electrical dilemmas.  

  • Overload

On the other hand, overload may refer to the running overcurrent that flows in full-load rating in a long and sustained time. When this happens, wires that could only handle a minimal or regular amount of current may pop out. Typically, it melts wires and other electrical parts exposed to overload due to overheating. 

  • Short Circuits 

A short circuit refers to the abnormal connection of two points with opposite voltages in layman’s terms. Excellent and safe connections, the points don’t resist. Thus, they don’t create an irregular link. When short circuits happen, the current flow may become excessive and lead to serious damage to the electrical system.

Components Of A Post D Breaker 

Typically, Post D breakers are grouped into different types and configurations. There are miniature types and large types. They also differ in their number of poles and the value of amperage. Yet, many Post D breakers share the following components: 

  • Frame: This refers to the case of the breaker that keeps it in place. It also protects the breaker from outside elements. 
  • Contacts: These permit the electric flow of the current when the breaker shuts down. 
  • Operating Mechanism: This offers an avenue for the breaker to open and close. 
  • Arc Extinguisher: This counters the discharge that happens when contacts are open. 
  • Trip Unit: This turns the operating mechanism on when overload and other troubles occur.

Advantages Of Post D Breakers 

Many electricians go for Post D breakers because of their advantages. These include the following:

  • Easy To Install And Use 

Post-D breakers are simple to install. Generally, you’ll need to look for a blank panel space. Then, test the area if it has no electricity. After that, press the breaker to the blank panel and connect its wire to the system. You may just use a screwdriver for this installation.  

Lastly, it’ll help if you’ll label the circuit directory on the panel’s door for easy reference. In using the breaker, you just need to turn it off manually when you work on its area. Otherwise, the breaker will just shut off automatically whenever an overload or short circuit happens.  

  • Generally Safe 

Basically, circuit breakers are installed to ensure safety and avoid sudden electrical discharge. With Post D breakers, you’re guaranteed that you’ll be protected from electrical loads. However, you still need to be cautious whenever you open a panel because it could be hot. For this reason, you must wear protective gloves to prevent scalding. These are some of the collective ways to guarantee a safe and protected workplace.  

  • Cost-Effective 

Post-D breakers typically work for a very long time if no overloads and short circuits take place. As long as they’re in good running condition, they’ll just function perfectly. This way, you’ll not spend much on the breakers. In addition, many stores offer reconditioned breakers, which could be cheaper than the new ones.  

If you have old models, you could bring them to the stores providing a range of circuit breakers for servicing. When buying reconditioned breakers, you may need to check them thoroughly to ensure that they’ll work similarly to the brand-new types. 

  • Flexible 

Although Post D breakers are intended for substantial industrial applications, you may still install them in residential and commercial spaces. This enables you to install equipment and appliances, which require a lot of electrical loads. This way, you’re able to improve your electrical wiring system and load coverage.  

Wrapping Up 

Post D or Square D circuit breakers have revolutionized through the years since their makers introduced them to the electrical industry. Because of this, nowadays, there are many breakers you could choose from. You may pick the molded case or the miniature types. You may also look for specific models that’d match your electrical need. Lastly, you may consider the kind of vacant panel on your board. 

In choosing the best and most suitable one, you may need to assess your needs first. Are you working in a metal arc welding shop that usually consumes heavy electrical loads?  If this is the case, you may need a reliable Square D breaker to protect you from faulty connections and sudden electrical charges. 

If you’re unsure of what to pick and decide, you may go back to the insights you’ve gained from this article. You may also visit stores selling the said products, or ask seasoned local electricians as they may help you in deciding what type of circuit breaker could really help you and keep your property safe.
