Circuit Breaker Repair Nashville: How Long Do Circuit Breakers Last?

In the past 5 months I experienced a lot of breaker trips. Ironically, I was relaxed  when the circuit was watching my electric flaws. Unfortunately, this temporary satisfaction, which was actually negligence,damaged my electric panel. The main aim behind writing How Long Do Circuit Breakers Last? is to make you alert if you’re making similar mistakes.

We mostly keep the breaker out of mind until it expires.But like  anything else in your home,your breaker has a lifespan.Your proactive maintenance can extend its period on the other hand slight negligence will cause breakdown soon.

Average Lifespan of Circuit Breakers

The lifespan of a normal circuit breaker is 30-40 years. Sounds like a long life, doesn’t it? And it can be as long as everything is perfect. The breakers in many older Nashville homes are already at risk or have gone beyond their prime.

Average age for different types of breakers:

• Normal breakers – 30 to 40 years, if they’re well treated
• GFCI breakers – 15 to 25 years
• AFCI breakers – 20 to 30 years

One of the complicated things about circuits is they don’t show any clue when on the last stage. It just starts to falter until it doesn’t trip, or trips at the wrong time. Both are dangerous.

 Factors That Reduce Breaker Life

This is where homeowners including past-me generally get it wrong. The lifespan of a breaker is not simply a function of its age , it’s also a function of its wear and tear.

Frequent Tripping

The secret no one tells you is that each time your breaker trips, it damages little. Sure, it’s performing its function  but each time it trips, it generates mechanical and thermal stresses on the inside parts

I used to think repeated tripping indicated a happy breaker. In reality, it signalled that I had a circuit problem and the breaker was prematurely wearing out.It’s not normal for your breaker to trip once a week. That’s a warning sign.

Environmental conditions

Nashville summers are really hot and humid, and that’s tough on electrical equipment.

If breakers are installed in places like:

• Garages (where temperature goes up and down a lot)
• Basements (where there can be water or dampness)

These conditions can damage the outdoor panels without proper protection.Additionally,heat, moisture, dirt, and rust slowly damage them so instead of lasting 30 years they can wear out much sooner.

Signs Your Breaker Is Near the End of Its Life

Here are some of the red signs which your circuit shows before going to deathbed.

• Frequent tripping:The breaker trips often, even when you’re not using too much electricity
• Shut down after resetting:It won’t stay on after you reset it
• Burning Smell:One of the serious sign is, you smell something burning near the panel 
• Breaker Discolored: You see burn marks or discoloration on the breaker
• The breaker feels warm or hot, even when it’s off
• Lights flicker even though the breaker hasn’t tripped
• Aging Panel:Your electrical panel is 25+ years old and you haven’t planned any inspection yet
