Top FAQs on Circuit Breakers: Lifespan, Amperage Upgrades & Maintenance Tips

Every electrical system requires a circuit breaker to prevent events like overloads, short circuits and fire hazards. It’s very critical for every homeowner, facility manager and electrician to first understand how a circuit breaker works, how to choose the right one and how to maintain it. Today, we are also going to answer all such important circuit breaker FAQs for you to make a more informed buying decision.

Q1. What’s The Lifespan Of A Quality Circuit Breaker On Average?

One common question asked by many is “how long do circuit breakers last?”. Well, on average, circuit breakers can easily last between 30 to 40 years but it also falls down on the environmental factors and the usage of the breaker. Reputable manufacturers who create top notch quality circuit breakers, usually create designs that can last for decades but the actual lifespan depends on multiple factors including; 

• Tripping Frequency: If your breaker trips frequently, it’ll reduce its longevity. 

• Electricity Load: If you are installing your breaker near maximum load, it can cause some wear and tear to the components at a faster pace. 

• Maintenance: It’s important to get your breakers inspected regularly to detect and manage wear or any fault before time. 

• Environmental Factors: High temperatures, moisture and humidity, all these factors can lead to quicker degradation of a circuit breaker. 

If your breaker is more than 25 years old then it’s important to get it inspected by a professional. Especially if there’s frequent tripping or a buzzing sound coming out of the breaker then you should opt for professional evaluation. 

Q2. Is It Possible To Upgrade The Amperage Of A Circuit Breaker?

Want to know the answer to “can I upgrade amperage?”. Well, yes, it’s possible to upgrade the amperage of your circuit breaker but only under specific conditions and it’s advised to get it done by a licensed electrician. For example, if you want to upgrade from a 15A breaker to a 20A breaker then here are some important things you must consider before; 

• Safety Of The Outlet And The Device: Every device you connect must be rated as per the rating of the upgraded current. 

• Wiring Compatibility: Your wire gauge should be able to handle the upgraded higher amperage. For example, for 20A amperage, you should have a 12-gauge wire. 

• Capacity Of The Panel: Your service panel should be able to handle the load you are adding without exceeding the limit. 

An inadequate wire and a high amperage rating can become a serious fire hazard. The wire won’t be able to handle the current, and it can lead to overheating problems. It is of utmost importance to first consult a licensed electrician and get a circuit evaluation to ensure that you are making the right amperage upgrades. 

Q3. When and How Often Should I Get the Circuit Breakers Inspected or Maintained?

In order to make sure that there’s no corrosion or other wear and tear, it’s important to visually inspect your circuit breakers after every 6 months. On the other hand, in case of high load environments, you should get your breaker professionally inspected after every 3 to 5 years. In case of a major electrical event, you should immediately get your breaker inspected for safety purposes. Some important maintenance tips include; 

• Ensure that all the connections are tightened. Loose connections can lead to overheating issues and arcing. 

• You should clean the panel dust every now and then because dust can become a serious fire hazard. 

• If you have AFCI or GFCI breakers, then you should get them tested frequently to ensure proper functioning and safety.

• It’s important to label your circuits properly in order to avoid confusion during an emergency situation. 

Q4. What Are The Signs Of A Faulty Breaker?

You should look out for signs that indicate a faulty breaker and get it replaced immediately. 

• If your breaker is tripping frequently, even under normal load conditions.

• If the breaker feels warm or hot to the touch.

• The breaker has a weird burning smell.

• If the breaker doesn’t trip even during overloads.

• Rattling or buzzing noise or visible physical damage.

If you even have the slightest doubt about your breaker, it’s best if you get it replaced by a licensed professional. Breaker maintenance is of utmost importance.  A new breaker won’t cost you much, but using a damaged one can be dangerous and life-threatening too. 

Q5.Can I Install A Circuit Breaker Myself?

DIY installation of a circuit breaker is a huge risk, especially if you aren’t qualified to do it. It’s highly recommended to hire a professional electrician for the installation for safety purposes. Improper installation of a circuit breaker can lead to fire hazards, electric shock,s and it’s also a code violation. 

Q6. Is It A Good Idea To Install Smart Circuit Breakers?

Yes, smart circuit breakers are the best choice, especially if you want to track the power usage in real time. Not only this, but you can turn on and off the breakers via your mobile applications. In case of any unusual behaviour or trips, you’ll get alerts, and the best thing about these breakers is that you can connect your panels with your home automation systems. In a nutshell, investing in a smart circuit breaker is a wise decision, and it’ll give you the best value for your money, too! 

Overall Verdict

In order to improve the safety of your home or industrial/commercial properties, it’s important to first understand the basics of a circuit breaker, how it works, what its lifespan and how to maintain it. All these things can help you prevent a major electrical accident. Most importantly, even though DIY installation is helpful, you should still try to hire a professional electrician to get your panels and breakers inspected and installed.
