Why Do Circuit Breakers to Wear Out Over Time?
Circuit breakers are important safety features in your home’s electrical system. By interrupting and breaking overloaded circuits in your home, they can prevent electric shocks, fires, and damage to your electronics and appliances. It can be annoying when a circuit breaker trips, but in most cases it can be reset with the flip of a switch.
While circuit breaker boxes are much more convenient than the fuse boxes they’ve largely replaced, circuit breakers themselves can still wear out and go bad over time. This can cause serious electrical problems, so it’s important to know when a circuit breaker may be failing so that it can be replaced as soon as possible.
How Circuit Breakers Work
A circuit breaker usually keeps an electrical circuit closed and allows electricity to flow freely. When a circuit breaker detects a short circuit or overload, it breaks the circuit and interrupts the flow of electricity. Flipping a switch will reset the breaker and close the circuit again.
As we said before, circuit breakers are important safety features in any electrical system. Overloads and short circuits can result in serious damage to your home, so you need this kind of safety feature in place.
Unfortunately, circuit breakers can and do suffer from wear and tear just like anything else, and they can leave your home unsafe as they wear out. This is often caused by the strain of frequently overloaded circuits, power surges, and short circuits, but it also occurs in homes with faulty wiring. Age and environment are factors as well. Too much humidity can cause the elements of your circuit breakers to corrode and eventually fail, while older breakers may have simply weakened over time.
Signs of Worn-Out Circuit Breakers
If you live in a newer home with a recently upgraded electrical panel, it’s unlikely that your breakers have worn out unless you have a serious humidity problem in your house. On the other hand, an electrical panel that is over 25 years old might have some worn-out breakers that should be replaced. Signs of a failing circuit breaker include:
- Frequent tripping
- Visible damage such as burn marks or corrosion
- A buzzing or humming noise coming from the electrical panel
- A breaker that is hot to the touch
- Difficulty resetting a circuit breaker after it trips
If you notice any of these issues in your home, contact an electrician to schedule an electrical panel inspection. Even though you’ll likely notice signs of a worn-out circuit breaker, an electrician is still needed to make the final diagnosis and to replace any breakers that may be wearing out.
Frequently Asked Questions
How long do circuit breakers typically last?
Most circuit breakers last 25 to 40 years, but their lifespan depends on how often they trip, the quality of the electrical system, and environmental conditions like heat and humidity.
Can I keep resetting a breaker that trips often?
No. A breaker that trips repeatedly is warning you about an overload, short circuit, or possible breaker failure. It’s best to have a licensed electrician inspect the problem rather than continually resetting it.
What causes circuit breakers to wear out faster?
Frequent overloads, power surges, short circuits, aging components, moisture, and corrosion can all shorten the life of a circuit breaker.
Is a warm circuit breaker always a problem?
A slightly warm breaker can be normal under heavy electrical use, but a breaker that’s hot to the touch, smells burnt, or shows discoloration should be inspected immediately.
Should I replace a bad circuit breaker myself?
Circuit breaker replacement should always be handled by a licensed electrician. Working inside an electrical panel is dangerous and requires the proper training to ensure your home’s electrical system remains safe and up to code.
