You’re juggling dinner, laundry, and maybe a bit of homework help. The microwave’s running, the dryer’s humming — and then everything goes quiet. The lights cut out. The appliances stop.
Another trip to the breaker box. Another reset. Another “Why now?”
A circuit breaker that keeps tripping isn’t just annoying. It’s your home’s way of signaling that something might be off.
Sometimes the reason is simple. Other times, it’s a warning you don’t want to ignore.
In this article, we’ll walk you through the most common causes of tripped breakers, how to know when it’s a quick fix, and when it’s time to call in a licensed electrician, like our trusted team at PDX Electric.

Why Does the Circuit Breaker Keep Tripping? 4 Common Causes
When your breaker trips, it’s doing its job — cutting power to prevent overheating, damage, or even electrical fires. But if it’s happening often, there’s usually an underlying issue that needs attention.
There are several possible reasons a breaker might keep tripping. Some are minor and easy to resolve, while others point to more serious electrical concerns. Here are four of the most common causes:
Circuit overload
Overheating appliance
Short circuit
Ground fault
In the next sections, we’ll break these down one by one — what they mean, how to spot them, and what you can safely do about them. And if you’d rather skip the guesswork? That’s where PDX Electric comes in. Our licensed electricians help Portland-area homeowners quickly diagnose and fix breaker issues with no stress and no surprises.
#1: Circuit Overload
A circuit overload happens when too many devices or appliances draw power from the same circuit at once. This causes the breaker to trip to prevent overheating.
How to tell:
The breaker trips when using multiple devices at once.
Lights flicker or dim before the trip.
What to do:
Unplug some devices and spread them across different outlets.
Avoid running high-power appliances on the same circuit simultaneously.
If overloads keep happening, consider having an electrician add circuits or upgrade your panel.
#2: Overheating Appliance
Some appliances, like space heaters, refrigerators, or dryers, can overheat if they’re working too hard or have a mechanical issue. Overheating can cause the circuit breaker to trip as a safety measure.
How to tell:
The breaker trips when a specific appliance is running.
The appliance feels unusually hot or smells burnt.
The breaker stays off until the appliance cools down.
What to do:
Unplug the appliance and let it cool before resetting the breaker.
Check for blocked vents, dust buildup, or worn parts.
If the problem persists, stop using the appliance and call a professional for repair or replacement.
#3: Short Circuit
A short circuit happens when a hot wire touches another wire or a metal part, causing a sudden surge of electricity. This is dangerous and causes the breaker to trip immediately.
How to tell:
The breaker trips as soon as you turn on an appliance or light.
You might see sparks, hear buzzing, or smell burning near outlets or switches.
There are frequent trips on the same circuit.
What to do:
Turn off the power at the breaker panel.
Avoid using the affected outlets or appliances.
Call a licensed electrician to inspect and fix wiring issues safely.
#4: Ground Fault
A ground fault happens when electricity takes an unintended path to the ground — often through water or damaged wiring. This creates a shock risk and trips the breaker to keep you safe.
How to tell:
The breaker trips when using outlets near water (bathrooms, kitchens, or outdoors).
You might feel a slight shock when touching an appliance or outlet.
The breaker may be a Ground Fault Circuit Interrupter (GFCI) type, designed to detect these faults.
What to do:
Avoid using the outlet or appliance until it’s checked.
Look for water leaks, damaged cords, or loose connections.
Have a licensed electrician inspect and repair the issue promptly.
How To Know When the Circuit Breaker Has Tripped
The most obvious sign that a circuit breaker has tripped is a loss of power in part of your home. Maybe the lights go out in one room, or an outlet suddenly stops working.
Other signs to watch for include:
Burning smell or faint buzzing near your breaker panel or outlets
Lights flickering or dimming before the power cuts out
Unusual noises, like clicking, coming from the breaker box
A breaker switch that’s in the “off” or middle (neutral) position instead of fully “on”
If you notice any of these, it’s a good idea to check your breaker panel before assuming there’s a larger electrical outage.
What Steps To Take When the Circuit Breaker Is Tripped
When your circuit breaker trips, it’s important to handle it carefully and methodically to keep your home safe and avoid further issues. Here’s a simple checklist to guide you through the process:
Locate your breaker panel and open the door.
Identify the tripped breaker — it will be in the “off” or middle position.
Turn the breaker fully off, then switch it back on.
Unplug or turn off devices on the affected circuit to prevent immediate overload.
Plug devices back in one at a time to test if any cause the breaker to trip again.
If the breaker trips repeatedly, stop using the circuit and call a licensed electrician.
Never force a breaker to stay on if it keeps tripping. It’s protecting your home.

FAQs About Tripped Circuit Breakers
What Is the Most Common Reason for a Circuit Breaker To Trip?
The most common reason a circuit breaker trips is circuit overload, when too many devices draw power on the same circuit, causing it to exceed its limit and shut off to prevent overheating.
Overloading happens easily in homes with multiple electronics, appliances, and lighting on one circuit. This puts stress on your electrical system and causes the breaker to trip frequently. Spreading out your devices or upgrading your electrical panel can help prevent this issue.
Is It Safe if the Breaker Keeps Tripping?
It’s not safe if your breaker keeps tripping frequently. It’s a warning sign of potential electrical problems that could lead to damage, overheating, or even fire hazards if left unaddressed.
Repeated breaker trips can cause:
Damage to appliances and electronics
Increased risk of electrical fires
Wiring deterioration or shorts
Unexpected power outages disrupting your daily life
Ignoring these signs puts your home and family at risk. It’s important to diagnose and fix the cause promptly, ideally with the help of a licensed electrician like the team at PDX Electric.
How Do I Find What Is Tripping My Circuit Breaker?
To find what’s tripping your circuit breaker, identify the affected circuit, unplug devices, and reset the breaker. Then, plug in and turn on devices one at a time to see which causes the trip.
Start by locating your breaker panel and noting which breaker has switched off or is in the middle position. Unplug all devices on that circuit and reset the breaker. Gradually plug devices back in and turn them on individually to spot the culprit. If the breaker trips immediately when you plug in a specific device or appliance, that’s likely the problem.
If the cause isn’t obvious or the breaker continues to trip without an obvious trigger, it’s best to call a licensed electrician. They can safely diagnose and fix wiring or appliance issues.
Is There a Way To Keep the Circuit Breaker From Tripping?
While some breaker trips are unavoidable, there are steps you can take to reduce how often they happen and keep your electrical system running smoothly:
Avoid plugging too many devices into one circuit.
Unplug appliances when not in use.
Upgrade old or undersized electrical panels and breakers.
Regularly inspect and maintain appliances for signs of wear or overheating.
Use dedicated circuits for high-power appliances like dryers or space heaters.
Keep your breaker panel clean and free of dust.
If your breaker still trips frequently despite these efforts, it’s time to call in the pros.
