If your circuit breaker keeps tripping, it almost always means one of three things: the circuit is overloaded, you have a short circuit somewhere, or there is a ground fault. Most overloaded circuits can be fixed for free by moving devices to other outlets. A short circuit or ground fault will require a licensed electrician, costing between $150 and $500 for diagnosis and repair. If your breaker trips immediately when reset, or you smell burning, stop using that circuit and call a pro right away.
This is one of those home problems that sounds simple on the surface, but it is worth taking seriously. Electrical issues are the third leading cause of house fires in the United States, according to the National Fire Protection Association (NFPA). Taking a few minutes to understand what is happening in your panel can protect your family and your home.
What Does a Circuit Breaker Actually Do?
Think of your circuit breaker as a safety valve. Every circuit in your home has a limit, measured in amps, for how much electrical current it can safely carry. When that limit is exceeded, the breaker trips (switches off) before the wiring can overheat and start a fire.
Your electrical panel typically has breakers ranging from 15 to 20 amps for general circuits, with larger 30 to 50 amp breakers for appliances like your dryer, oven, or air conditioner.
The Three Main Reasons a Breaker Keeps Tripping
1. Overloaded Circuit (Most Common)
An overloaded circuit is the most common reason a breaker trips, and the least dangerous. It simply means you are drawing more electricity than the circuit can handle.
Signs this is your problem:
- The breaker trips when you run multiple appliances at once
- It only trips under heavy use (running the microwave and toaster together, for example)
- No burning smell, no scorch marks
Common culprits:
- Kitchen circuits running a microwave, coffee maker, and toaster simultaneously
- A bedroom circuit with a space heater, TV, and multiple device chargers
- A shared circuit for your washer and another appliance
What you can do: Move some devices to outlets on a different circuit. To find which outlets share a circuit, flip the tripping breaker and see which outlets go dead. Move the high-draw appliance to a live outlet in a different room.
If you routinely need more power in a specific area, an electrician can add a dedicated circuit. This costs $200 to $750 depending on your home’s layout and your local rates.
2. Short Circuit (More Serious)
A short circuit happens when a “hot” wire (the live wire carrying current) accidentally touches a neutral wire. This creates a sudden surge of electricity far beyond what the circuit can handle, causing the breaker to trip almost instantly.
Signs this might be your problem:
- The breaker trips immediately when reset, even with nothing plugged in
- You notice a burning smell or see scorch marks around an outlet or switch
- You heard a pop or buzz when the breaker tripped
Short circuits can happen inside your walls, inside a faulty appliance, or at a damaged outlet. If you find a discolored or melted outlet plate, do not use that outlet again until it has been inspected.
What you can do: Unplug everything on that circuit, reset the breaker, and plug devices back in one at a time to find if the problem is in an appliance vs. the wiring itself. If the breaker trips with nothing plugged in, the problem is in your wiring. Call a licensed electrician immediately.
3. Ground Fault (Common in Kitchens and Bathrooms)
A ground fault occurs when a hot wire touches a grounded surface, like a metal outlet box or even wet flooring. It is similar to a short circuit but typically happens near water.
You are most likely to see this in your bathroom, kitchen, garage, or outdoors. These areas are supposed to have GFCI (ground fault circuit interrupter) outlets, the ones with the small “Test” and “Reset” buttons built in.
Signs this might be your problem:
- The issue is on a circuit in or near a bathroom, kitchen, laundry room, or outdoor area
- Your GFCI outlet has its reset button popped out
- The problem started after exposure to moisture
What you can do: First, try pressing the Reset button on your GFCI outlet. If it does not stay in, or immediately pops out again, the outlet may need replacement. A GFCI outlet costs $15 to $40 at a hardware store. Replacing one is a moderately easy DIY project, but if you are not comfortable working with wiring, hire an electrician.
Less Common But More Serious Causes
Worn-Out Breaker
Breakers are designed to last 30 to 40 years, but they do wear out. An old or faulty breaker may trip under loads it should easily handle, or fail to trip when it should (which is more dangerous than one that trips too often).
If your home was built before 1990 and you have never had your panel inspected, it is worth having an electrician check the breakers for wear.
Arc Fault
Arc faults happen when electricity “jumps” between conductors, which can occur inside walls with damaged wiring. They are a major cause of house fires. Many newer panels have AFCI (arc fault circuit interrupter) breakers, which are specifically designed to catch these. If your home does not have AFCI breakers, ask an electrician about upgrading.
Outdated Electrical Panel Brands
Certain older breaker brands have documented safety issues. Federal Pacific Electric (FPE) Stab-Lok panels and Zinsco/GTE-Sylvania panels have been found to fail to trip under overload conditions. If you have one of these panels, consider replacement regardless of whether your breakers are currently tripping. A full panel replacement runs $1,500 to $4,000.
Cost to Fix a Tripping Circuit Breaker
| Problem | DIY Cost | Pro Cost |
|---|---|---|
| Overloaded circuit | Free (redistribute loads) | $200-$750 (add dedicated circuit) |
| Faulty GFCI outlet | $15-$40 (replace outlet) | $100-$200 |
| Short circuit in appliance | Free (replace appliance) | N/A |
| Short circuit in wiring | Do not DIY | $200-$500 |
| Replace single breaker | Do not DIY | $150-$300 |
| Full panel replacement | Do not DIY | $1,500-$4,000 |
Electrician rates vary significantly by region. Expect to pay on the high end in California, New York, Washington state, and Hawaii. The Midwest and South tend to have lower labor rates.
DIY vs. Call a Pro: A Clear Decision Guide
You can handle these yourself:
- Moving devices to different outlets (free)
- Pressing the Reset button on a GFCI outlet
- Replacing a GFCI outlet (if you are comfortable with basic wiring)
- Replacing a damaged extension cord or power strip
Call a licensed electrician for these:
- Breaker trips immediately on reset with nothing plugged in
- Any burning smell, scorch marks, or melted plastic
- Breaker that feels warm or hot to the touch
- Problems that started after water damage
- Breaker will not stay in the reset position
- Any work inside the electrical panel itself (swapping breakers, adding circuits)
- Any wiring work inside walls
Never open your electrical panel yourself unless you are a licensed electrician. Even when the main breaker is turned off, the wires connecting from the utility are still live and can deliver a fatal shock.
How to Safely Reset a Tripped Breaker
If your breaker has tripped, here is how to reset it properly:
- Identify the tripped breaker. Tripped breakers sit in a middle position between On and Off, or may be labeled “Tripped.” Some have a small indicator window that turns red.
- Reduce the load first. Unplug or turn off devices on that circuit before resetting.
- Push the breaker firmly to Off. You need to fully switch it off before switching it on.
- Flip it firmly to On. You should feel a click.
- If it trips again immediately: Stop, do not keep resetting it. This is a sign of a serious issue. Call an electrician.
When to Call an Electrician Right Now (Do Not Wait)
Some situations are not a “schedule something this week” problem. Call an electrician or your utility company immediately if you notice:
- Sparks at an outlet or the panel
- A burning or smoky smell from any outlet, switch, or the panel
- A buzzing or crackling sound from the walls or panel
- The panel box itself feels warm or hot
- Lights flickering or dimming beyond one circuit
- Any sign of rodent damage to wiring (droppings near the panel, chewed wire insulation)
If you see sparks or smell smoke, do not just call an electrician: call 911.
What to Expect When the Electrician Arrives
For a tripping circuit breaker, a good electrician will:
- Ask you about when it trips, which appliances are involved, and how long it has been happening
- Inspect the panel for signs of overheating, loose connections, or damaged breakers
- Test the circuit with a multimeter to identify the fault
- Check outlets on the affected circuit for damage or wiring issues
- Give you a written estimate before doing any work
Labor rates for a licensed electrician run $75 to $150 per hour in most US cities. Diagnostic calls typically include a service fee of $50 to $150. Always ask for a licensed and insured electrician. You can check license status through your state’s licensing board.
Finding a Licensed Electrician
- Your state’s contractor licensing board: Search “[your state] electrical contractor license lookup” to verify credentials before hiring.
- NECA (National Electrical Contractors Association) at necanet.org maintains a directory of member contractors.
- Ask your neighbors and neighbors’ neighbors: Word of mouth is still the most reliable way to find a good electrician in your area.
- Get three quotes for any job over $500. Prices vary widely, and a very low quote can indicate unlicensed work or shortcuts.
Frequently Asked Questions
How many times can I reset a tripping breaker? Once or twice is fine if the cause is an overload you have already corrected. Resetting it repeatedly without solving the underlying problem is dangerous and can damage the breaker itself.
Is a tripping breaker an emergency? An overloaded circuit that trips when you run too many appliances is not an emergency. A breaker that trips immediately on reset, smells like burning, or is accompanied by flickering lights throughout the house is an emergency.
Can I replace a circuit breaker myself? Technically, you can buy and install a breaker yourself in most states. But it is not recommended. Mistakes can cause house fires or electrocution, and improper installation can void your homeowner’s insurance coverage for fire-related claims.
How long do circuit breakers last? Most breakers last 30 to 40 years. If your panel is older than 25 years, an inspection is a good idea even if you are not having issues.
Why does my breaker trip at night? Overnight trips are often related to HVAC systems cycling on, particularly heat pumps and older air conditioners that draw a large surge of power on startup. This is worth investigating with your HVAC technician.
