How a Circuit Breaker Works

Circuit breakers protect wiring from dangerous overcurrent conditions, including overloads and short circuits. When the breaker detects too much current on the circuit, it trips. This breaks the connection along the circuit, preventing the circuit from receiving power. By doing so, the circuit breaker protects your wiring and appliances from overheating and fires.

A tripped breaker is different from a power outage. In an outage, power to your entire home is temporarily stopped. A breaker is a safety mechanism that affects a single circuit. If a breaker repeatedly trips or fails to reset, professional circuit breaker repair can help identify and correct the underlying electrical problem.

Why Do Circuit Breakers Trip?

Circuit breakers monitor the flow of electricity to prevent short circuits, electrical overloads, and other dangers. They interrupt the circuit when current exceeds safe limits. Because of this, circuit breakers play a key role in preventing fires and equipment damage.

Common Causes of Breaker Trips

Why does my breaker keep tripping? While breaker trips usually involve overcurrent or fault conditions, the underlying trigger can vary significantly. To learn more about the causes of breaker trips, read on. 

Overloaded Circuit

One of the most common reasons why a circuit breaker keeps tripping is circuit overload. Basically, there are too many devices plugged into one circuit. If you have a 15-amp circuit, it doesn’t take long for too many devices to overwhelm its capacity.

Common Symptoms

• Tripped breaker
• Dimming lights
• Burning odors
• Buzzing sounds
• Warm outlets

Recommended Solution

In the short run, you should remedy this problem by distributing appliances across different circuits. If this is a frequent issue, you may want to consider a panel upgrade or rewiring your home so that your home’s electrical system has a larger electrical capacity.

Short Circuit 

A short circuit occurs when a hot wire comes into contact with a neutral or ground wire. This causes the current to surge, which can trip the breaker. 

Common Symptoms

• Melted or burned insulation
• Burning odors
• Flickering or dimming lights
• Cracking or popping noises
• Frequently tripped breakers
• Sparks
• Malfunctioning appliances

Recommended Solution

Short circuits can stem from a range of problems, such as faulty wiring, malfunctioning appliances, or loose connections. To remedy this issue, you need to schedule a professional electrical inspection.

Ground Fault 

Ground faults occur when electricity takes a different path, such as through a person or water. This problem is more common when frayed wires and water are present.

Common Symptoms 

• Flickering lights 
• Tripped GFCI breakers
• Burning odors
• Clicking and buzzing noises coming from the outlets

Recommended Solution

Because ground faults are more likely where water is present, kitchens and bathrooms typically require GFCI-protected outlets or circuits. When a GFCI trips, it helps protect people from electric shock, severe burns, and electrical damage.

To detect the source of the ground fault, unplug every device from the circuit. Then, try the devices one at a time until you figure out which one was causing the problem. If the problem is the wiring, you’ll need to schedule a professional electrical inspection.

Faulty Appliances 

Another common reason a circuit breaker keeps tripping is a faulty appliance. A malfunctioning appliance may draw more current than expected, overload the circuit, or develop an internal short circuit or ground fault. If the breaker consistently trips when one particular appliance starts or runs, the appliance may be contributing to the problem.

Common Symptoms

• Instant tripping when the unit turns on
• Burning odors
• Scorch marks around the plugs and outlets
• Warm plug, wall plates, or power cords
• Tripped GFCI breaker

Recommended Solutions

In this case, the best course of action is to get a professional electrical inspection to make sure the appliance hasn’t caused any lasting damage. Additionally, you should have the appliance repaired or replaced.

Loose or Damaged Wiring

Over time, wiring can become damaged or loose. Older homes that have aluminum wiring are especially prone to this issue because of how the aluminum expands and contracts over time.

Common Symptoms

• Warm outlet covers and switch plates
• Burning odors
• Buzzing and crackling noises
• Scorch marks around outlets and switches
• Flickering lights

Recommended Solutions

In this situation, the best thing you can do is shut off the main breaker and call for repairs. You should not attempt to access or repair wiring on your own. Instead, note the symptoms that are occurring, such as which outlets feel warm or when flickering lights occur.

Aging Circuit Breaker

Eventually, circuit breakers can start to age. Components can become worn and more likely to malfunction. Circuit breakers often last 30 to 40 years, but they can fail earlier if damaged, overloaded, or frequently tripped.

Common Symptoms

• Inability to reset the breaker
• Melting or burning odors
• Buzzing noises
• Warm panel covers and breaker switches
• Frequent, unexplained tripping

Recommended Solutions

The best way to solve this issue is by scheduling a replacement. Our team of electricians can evaluate your current capacity needs and help you choose the right breaker replacement or panel upgrade.

Outdated Electrical Panel

Many older, 100-amp electrical panels were designed for smaller loads. Now that homes have gaming systems, multiple televisions, smart home appliances, and other gadgets, they require a higher capacity.

Common Symptoms

• Burning smells
• Frequent tripping 
• Scorch marks
• Flickering lights
• Crackling or buzzing noises
• Warm panel surfaces

Recommended Solutions

Our electricians can evaluate your system to determine if it’s possible to rebalance the electrical load or replace individual breakers. If these solutions aren’t possible, it may be time to upgrade to a 200-amp panel.

Moisture Intrusion

When moisture gets into your panel and electrical systems, it creates an alternative path for the electricity to travel. This results in a short circuit or ground fault.

Common Symptoms

• Moisture near your panel
• Tripped breakers occur during rainstorms, lawn watering, or high-humidity days
• Breakers trip again immediately after being reset
• GFCI buttons pop and can’t be reset

Recommended Solutions

The first step is removing any water sources. For outdoor panels, you should replace old gaskets and use a weatherproof cover. You should also fix any roof or plumbing leaks.

Never touch wet circuits when you’re trying to turn the breaker off. Instead, call our team for help. We can also assist with inspecting underground lines for cracked conduits, replacing corroded breakers, and repairing other electrical components.

Incorrect Breaker Size

If the breaker is the wrong size, it may not be properly matched to the circuit wiring or expected load.

Common Symptoms

• Breaker trips immediately when you turn an appliance on
• Flickering lights
• Burning odors
• Tripping after 15+ minutes of running multiple devices due to gradual thermal overload
• Warm breaker switches

Recommended Solutions

The breaker should match the wire gauge. One of our licensed electricians can remove an improperly sized breaker and replace it with the appropriate size. We can also upgrade your electrical service to a 200-amp panel. 

For minor issues, you may be able to resolve the problem by splitting heavy loads. Large appliances, like dryers and HVAC appliances, should generally be on a dedicated circuit.

Motor Inrush Current (If Applicable)

This can occur if a motor draws a massive surge of electricity. For example, this can occur with HVAC equipment, well pumps, or table saws.

Common Symptoms

• Tripped breakers as soon as the device powers on
• The circuit works the rest of the time
• Dimming lights
• Circuit and electrical components don’t feel warm because it isn’t an overload trip

Recommended Solutions

A soft starter can be installed so that the motor can slowly ramp instead of causing a massive spike. Alternatively, an electrician can determine whether the circuit should be redesigned or upgraded to safely handle the load. A properly rated breaker or dedicated circuit may be recommended after professional testing.

Frequent Causes and Solutions for Tripped Breakers

Frequent Warning Signs Before a Breaker Trips

While the symptoms can vary based on the underlying cause, there are a few common warning signs that can appear before a breaker trips.

• Flickering lights
• Frequent dimming
• Sparks
• Buzzing noises
• Warm outlets and panels
• Burning odors

What You Can Do Before Calling an Electrician

Whenever you are uncertain about the problem, call one of our licensed electricians for help. There are also a few key steps you can take before reaching out for professional circuit breaker repairs.

• Turn Off Connected Appliances: First, unplug every device that is connected to the affected branch circuit. 
• Reset the Breaker: Once everything has been successfully unplugged, go to the breaker panel to reset the breaker. If it immediately trips, you should stop troubleshooting and call for repairs.
• Plug Devices Back in One at a Time: After the breaker has been reset successfully, plug each device back in one by one to see if any of them trip the breaker. You should also note any signs that the appliance might be damaged, such as burning odors, performance issues, or visible signs of damage. 
• Check for Overloaded Circuits: Redistribute how many appliances are on the affected circuit. Some larger appliances, such as HVAC systems and washer/dryer units, are often placed on dedicated circuits because of how much energy they draw.
• Inspect Outlets for Visible Damage: Check each outlet for signs of scorch marks, burning odors, or signs of warmth. However, you should not touch damaged or wet components.
• Test GFCI Outlets: On a GFCI outlet, there is a test button that simulates a ground-fault condition. Try pressing this button. If the GFCI outlet trips, then it is working correctly. 
• Stop if the Breaker Trips Immediately: Don’t reset your circuit breaker when there is a burning smell present. If the breaker immediately trips after you reset it, stop resetting it because there is likely an underlying problem that needs to be resolved. If you don’t know why a tripped breaker occurred, you should always seek professional help. 

How To Safely Reset Your Breaker
