As an expert in electrical systems, I can confirm that circuit breakers, like any other mechanical device, can indeed go bad. They are designed to protect electrical circuits from damage caused by overload or short circuit. Over time, the wear and tear, along with various environmental factors, can impact the functionality of a circuit breaker.
Causes of Circuit Breaker Failure:
1. Mechanical Wear: The repeated tripping and resetting of a breaker can lead to mechanical wear, which may eventually cause the breaker to fail to trip or reset properly.
2. Corrosion: Moisture and other environmental elements can cause corrosion within the breaker, affecting its electrical contacts and leading to poor conductivity or failure.
3. Overloading: If a circuit is consistently overloaded, the breaker may not trip as it should, indicating a potential malfunction.
4. Age: Older circuit breakers may not meet modern safety standards and can fail due to outdated design or materials.
5. Poor Installation: Improper installation can lead to a variety of issues, including incorrect wiring that can cause the breaker to malfunction.
6. Manufacturing Defects: Although rare, manufacturing defects can cause a breaker to fail prematurely.
Signs of a Faulty Circuit Breaker:
1. Inconsistent Tripping: If a breaker trips without a clear reason or does not trip when it should, it may be faulty.
2. Flickering Lights: This can be a sign of an overloaded circuit, which might be due to a malfunctioning breaker.
3. Buzzing Noises: Unusual sounds coming from the breaker panel could indicate a problem with the breaker itself.
4. Warm Breaker: A breaker that feels unusually warm to the touch may be struggling to handle the current it's supposed to manage.
5. Visual Damage: Visible signs of damage, such as cracks or burn marks, are clear indicators that a breaker needs to be replaced.
**What to Do If a Circuit Breaker Goes Bad:**
1. Safety First: Always ensure your safety by turning off the main power supply before attempting to inspect or replace a breaker.
2. Inspection: Visually inspect the breaker and its connections for signs of damage or wear.
3. Consult a Professional: If you suspect a breaker is bad, it's best to consult with a licensed electrician to diagnose and replace it.
4. Replacement: If a breaker is confirmed to be faulty, it should be replaced with a new one that is appropriate for the circuit it protects.
Preventive Measures:
1. Regular Maintenance: Regularly inspect and maintain your electrical system to catch potential issues early.
2. Avoid Overloading: Do not connect more devices to a circuit than it is rated for.
3. Proper Installation: Ensure that all electrical work is done by qualified professionals to avoid installation-related issues.
In conclusion, while circuit breakers are robust devices designed for safety, they are not immune to failure. Regular inspection, proper use, and prompt attention to signs of malfunction can help prevent issues and ensure the continued safety and reliability of your electrical system.

If the switch flops back and forth and there is not definite --on-- or --off-- position, the breaker is probably bad. If the circuit breaker does NOT trip immediately: Chances are you have an overloaded circuit, meaning that the circuit has more electricity flowing through it than it is rated for.Mar 16, 2015
