A circuit breaker keeps tripping because of one of three root causes: a circuit overload, a short circuit, or a ground fault. Each cause has a different fix, and knowing which one you are dealing with helps you decide whether to handle it yourself or call a licensed electrician right away.
This guide walks you through how to diagnose the problem, what steps are safe to take on your own, and what warning signs mean you need professional help. Homeowners and renters across Pasadena, Glendale, Burbank, Studio City, Hollywood, and the broader Los Angeles area deal with this issue regularly, especially in older homes with aging electrical panels.
Understand Why a Circuit Breaker Keeps Tripping
A circuit breaker is a safety device. It trips, meaning it shuts off power to a circuit, when it detects more electrical current than the circuit is rated to handle. That is a good thing. It is protecting your wiring and your home from overheating and potential fire.
The three most common reasons a circuit breaker keeps tripping are outlined below.
- Circuit overload: Too many devices drawing power from a single circuit at the same time. This is the most common cause and the easiest to fix.
- Short circuit: A hot wire touches a neutral wire inside an outlet, switch, or appliance. This causes a large surge of current and is more serious.
- Ground fault: A hot wire contacts a ground wire or a grounded surface. This is common in bathrooms, kitchens, garages, and outdoor areas where moisture is present.
- Worn or faulty breaker: Older breakers, especially in homes built before the 1980s in areas like North Hollywood, Van Nuys, and Sherman Oaks, can simply wear out and trip even under normal loads.
Identifying which of these is happening is the first step toward a real solution. Resetting the breaker without understanding the cause is just delaying the problem.
Follow These Steps When Your Breaker Trips
Before calling anyone, there are a few safe diagnostic steps you can take on your own. These will also give a licensed electrician useful information if you do need to call one.
- Do not immediately reset the breaker. First, turn off or unplug every device connected to that circuit. Resetting under load can damage the breaker.
- Locate the tripped breaker in your panel. A tripped breaker will sit in a middle position between ON and OFF, or may show a red indicator window depending on your panel brand.
- Reset it properly. Push the breaker fully to the OFF position first, then firmly flip it back to ON. A partial reset will not restore power.
- Plug devices back in one at a time. If the breaker trips again quickly after plugging in a specific appliance, that appliance may have a short circuit inside it. Stop using it immediately.
- Check for burning smells or visible scorch marks. If you smell burning plastic or see any discoloration around outlets or the panel, stop and call an electrician. Do not reset the breaker.
- Note the pattern. Does it trip only when a specific appliance runs? Does it trip at the same time every day? This information helps diagnose the cause.
If the breaker trips again immediately after resetting even with nothing plugged in, you likely have a short circuit or ground fault in the wiring itself. That requires a professional inspection.
Identify Overloaded Circuits in Your Home
Circuit overloads are the most common reason a circuit breaker keeps tripping in residential homes. Most standard household circuits are rated for 15 or 20 amps. High-draw appliances can push a circuit past that limit quickly.
| Appliance | Typical Amperage Draw | Risk on a 15-Amp Circuit |
|---|---|---|
| Microwave | 10-13 amps | High, especially if shared |
| Hair dryer | 10-15 amps | Very high |
| Space heater | 12-15 amps | Very high |
| Window AC unit | 7-12 amps | High in summer months |
| Vacuum cleaner | 6-11 amps | Moderate |
| Laptop charger | 1-3 amps | Low on its own |
The fix for an overloaded circuit is usually straightforward. Move some appliances to a different circuit, or stop running multiple high-draw devices at the same time on the same circuit.
If your home does not have enough circuits to support your appliances without overloading, the long-term solution is adding dedicated circuits. This is a licensed electrician job and is especially common in older homes across West Hollywood, Culver City, and Downtown Los Angeles where the original wiring was designed for far fewer electrical devices than modern households use.
Recognize When a Short Circuit or Ground Fault Is the Problem
Short circuits and ground faults are more serious than overloads. A short circuit happens when electrical current travels along an unintended path, usually due to damaged wiring, a faulty appliance, or a loose connection inside an outlet or switch.
Warning signs of a short circuit or ground fault include:
- The breaker trips immediately when you reset it, even with no appliances running.
- You notice a burning smell near an outlet, switch, or your electrical panel.
- An outlet or switch feels warm or shows discoloration or scorch marks.
- You hear a popping or buzzing sound when power is restored.
- The breaker trips only in a bathroom, kitchen, garage, or outdoor area, which points to a ground fault in a moisture-prone location.
Ground faults in wet areas should be protected by GFCI outlets or a GFCI breaker. If your home has older standard outlets in bathrooms or kitchens, upgrading to GFCI protection is both a safety improvement and required under current California electrical code.
Do not keep resetting a breaker that trips due to a short circuit. You are bypassing the only thing standing between that fault and a house fire.
Compare Common Electrical Panel and Circuit Issues by Cost
Knowing the general cost range for common fixes helps you budget and avoid surprise invoices. Prices vary depending on the scope of work, the age of your panel, and local permit requirements in cities like Glendale, Burbank, Encino, and Covina.
| Issue | Typical Repair Cost (Los Angeles Area) | DIY Possible? |
|---|---|---|
| Reset tripped breaker | Free | Yes |
| Replace a single circuit breaker | $150 to $300 | No, requires a licensed electrician |
| Add a dedicated circuit | $300 to $700 | No |
| Replace or upgrade GFCI outlet | $100 to $200 per outlet | Possible with experience |
| Full panel upgrade (100A to 200A) | $1,500 to $4,000 | No, permit required |
| Diagnose and repair wiring fault | $200 to $600+ | No |
Permit requirements in Los Angeles County mean panel upgrades and new circuit additions require a licensed contractor and city inspection. Kirk Star Electrical handles all permitting as part of the job, so you are not left managing that process on your own.
Know When to Call a Licensed Electrician Right Away
Some situations call for immediate professional attention. Trying to troubleshoot advanced electrical problems without proper training and tools can be dangerous and can also void your homeowner’s insurance in some cases.
Call a licensed electrician immediately if any of the following apply:
- The breaker trips repeatedly within seconds of being reset, even with nothing connected.
- You see sparking, scorch marks, or smoke near your panel or any outlet.
- Multiple breakers are tripping at the same time.
- Your panel is an older brand like Federal Pacific, Zinsco, or Pushmatic. These panels have known safety issues and are common in older homes in areas like Whittier, West Covina, and Universal City.
- You smell burning from your electrical panel itself.
- Lights flicker consistently on the same circuit even under normal load.

FAQs on Circuit Breaker Keeps Tripping
Why does my circuit breaker keep tripping with nothing plugged in?
If your circuit breaker keeps tripping even with nothing plugged in, you likely have a short circuit or ground fault somewhere in the wiring itself. This could be inside a wall, at an outlet, or at a fixture. This is not a DIY fix and requires a licensed electrician to locate and repair the fault safely.
Is it dangerous to keep resetting a tripping breaker?
Yes, repeatedly resetting a breaker without fixing the underlying cause is dangerous. The breaker is tripping to protect your wiring from overheating. Forcing it back on repeatedly can damage the breaker, overheat wiring inside your walls, and increase the risk of an electrical fire. Diagnose the cause first.
Can a tripping breaker be a sign of a bad breaker itself?
Yes. Breakers can wear out over time, especially in older homes. A faulty breaker may trip under normal loads or may stop tripping when it should, which is equally dangerous. If a breaker trips repeatedly without an obvious overload or fault, the breaker itself may need replacement by a licensed electrician.
How do I know if my electrical panel needs to be upgraded?
Signs that your panel may need an upgrade include frequent breaker trips, a panel rated at 100 amps or less in a home with modern appliances, a panel brand with known safety issues like Federal Pacific or Zinsco, or a panel that is more than 25 to 30 years old. A licensed electrician can evaluate your panel and give you a clear recommendation.
Why does my breaker trip only when I run the air conditioner?
Air conditioners draw a significant amount of current, especially when first starting up. If your AC is on a shared circuit or if the breaker is undersized for the unit, it will trip. A dedicated 20-amp or 30-amp circuit for your AC is often the right solution, and it requires a licensed electrician to install properly.
Does a tripping breaker affect other rooms in my house?
Usually a tripped breaker only cuts power to the specific circuit it controls, which may cover one room or a portion of a room. However, if a main breaker trips, it can cut power to the entire home. If you are losing power in multiple rooms at once from a single trip, the problem may involve your main breaker or your utility connection.
Wrap Up and Next Steps
A circuit breaker keeps tripping for a reason, and that reason is almost always something that needs a real fix, not just a reset. Start by identifying whether you have an overload, a short circuit, or a ground fault, and follow the diagnostic steps in this guide before calling for help.
For anything beyond a simple overload fix, trust a licensed electrician to handle it safely and up to California code.
