Breaker Keeps Tripping? Common Causes, Fixes, and When to Call an Electrician
You are reheating leftovers or powering up your hair dryer when suddenly click everything goes dark.
If your breaker keeps tripping, it can feel like your house is either haunted or trying to teach you an unexpected lesson in electrical safety.
If you are asking why does my breaker keep tripping or wondering why your circuit breaker keeps tripping even after resetting it, you are not alone. Tripping breakers are one of the most common residential electrical problems and they are rarely random.
In most cases, a circuit breaker that keeps tripping is your electrical system warning you about a real issue such as an overload, wiring problem, faulty appliance, or panel failure.
This guide explains what it means when a circuit breaker keeps tripping, the most common causes, what you can safely troubleshoot, and when it is time to call a licensed electrician in Colorado.
What’s Happening When a Circuit Breaker Keeps Tripping?
Your circuit breaker is like the bouncer for your electrical panel. If someone (like an overloaded appliance) tries to sneak in too much electricity, the breaker kicks them out. It does this by cutting power to a specific electrical circuit to prevent overheating, fires, or damaged appliances.
When a circuit breaker keeps tripping, it’s usually due to one of these troublemakers:
- Too much demand on one circuit (circuit overload)
- A wiring issue like a loose connection
- Moisture or a damaged neutral wire
- A misbehaving appliance
1. Circuit Overload: The Most Common Culprit
This is the electrical equivalent of trying to cram too many people into an elevator. When too many devices draw power on the same circuit, your breaker taps out.

Example:
Your microwave keeps tripping the breaker because it’s sharing a circuit with your toaster, blender, and maybe even the fridge.
What You Can Do:
- Unplug a few appliances and run them one at a time.
- Spread appliances across different electrical circuits.
- Use heavy-duty extension cords sparingly (and smartly).
Over time, recurring overloads can damage your breaker box or wiring, so don’t ignore them.
According to NEC Article 220, proper load calculations are required to prevent overloads. Just plugging things in and hoping for the best doesn’t cut it, especially in older homes.
2. Short Circuit: Sparks Aren’t Always Romantic
A short circuit happens when a hot wire touches a neutral wire or ground wire. This causes a sudden spike in electricity, which your breaker catches immediately.
Signs of a Short Circuit:
- Burn marks on outlets
- That distinctive burnt smell (never good)
- A pop or spark when plugging something in
Short circuits are dangerous and not DIY territory. If you suspect one, turn off the power and call an electrician.
3. Ground Fault: Water + Wires = Uh Oh
A ground fault happens when a hot wire comes into contact with a grounded part of a device or wall box, especially in areas with moisture, like bathrooms and kitchens.
That’s why your GFCI breaker keeps tripping in places like:
- Outdoor outlets
- Bathroom sockets
- Laundry room circuits
What to Do:
- Unplug everything from that circuit.
- Try resetting the breaker and plugging items in one at a time.
- If the breaker trips again instantly, call in the pros.
Ground faults are serious business, they can lead to electric shock.
4. Faulty Appliance: The Drama Queen of Your Outlets
Sometimes it’s not your wiring, it’s the appliance. If your microwave keeps tripping the breaker, but other devices don’t, it might be on its way to the great appliance graveyard in the sky.
How to Check:
- Try plugging it into a different outlet on a separate circuit.
- If it still trips the breaker, replace it.
- Still unsure? An electrician can test for internal faults.
5. Loose Connections and Wiring Errors
Over time, wiring connections inside outlets, switches, or your breaker box can loosen. Backstabbed receptacles, overtightened lugs, or creative (but unsafe) wiring like wrapping a ground wire around a neutral wire to spoof a return path can cause intermittent power flow and heat.
Watch for:
- Flickering lights
- Intermittent power loss
- Breakers that trip with no clear pattern
These aren’t just quirky annoyances, they can lead to arcing and fire hazards.

6. Breaker Failure: When the Breaker Is the Problem
Most people assume the breaker trips because something else is wrong. But sometimes the breaker itself is faulty. Components inside the breaker, like the bimetal strip, degrade over time, especially if it’s been tripped often.
Clues It Might Be the Breaker:
- It trips with no load or issue present
- It’s physically warm to the touch
- It fails to reset or resets inconsistently
Not all breakers are rated for frequent switching. If in doubt, have a professional inspect it. Contact The Electricians today.
7. Circuit Damage: The Hidden Threats
You can’t see inside your walls, but that’s where trouble might be lurking:
- Nails or screws puncturing wires
- Rodents chewing insulation
- Wires crushed behind walls or outlets
All of these increase resistance and can cause random breaker tripping.
8. Outdated or Unsafe Panels
Still rocking an old Federal Pacific or Zinsco panel? These legacy brands are known to fail under load and may not trip when they should. That’s worse than nuisance tripping, it’s a fire risk.
Warning Signs:
- Humming or buzzing panels
- Warm-to-the-touch breakers
- Tripping that seems random and increasing over time
If your panel is from the 70s or earlier, or has a brand with a bad reputation, it might be time for an upgrade.
9. Double-Tapped Breakers
We get it, you’re out of room in the panel. But tying two circuits into one breaker (unless it’s rated for it) is unsafe and a code violation.
What Can Happen:
- Overloaded breakers
- Heat buildup
- Improper disconnection during faults
NEC 110.3(B) states that devices must be installed in accordance with their listing and labeling. Most standard breakers are not rated for double taps.
AFCI & GFCI Tripping: Sensitive by Design
Arc Fault Circuit Interrupters (AFCIs) and Ground Fault Circuit Interrupters (GFCIs) are meant to be cautious. That means sometimes they’ll trip over small electrical noise or minor inconsistencies.
Common Triggers:
- Vacuum cleaners
- Older hair dryers
- Motor-driven tools
- Power surges
Sometimes it’s a nuisance. Sometimes it’s a warning. If your GFCI breaker keeps tripping or your AFCI trips often, let an electrician evaluate it.
How to Reset a Tripped Breaker (Safely)
- Locate your electrical panel
- Find the breaker between ON and OFF
- Switch it fully OFF, then back to ON
If it trips again immediately, stop and investigate or call an electrician. Repeatedly resetting a breaker without fixing the cause is unsafe.
Is It Dangerous If Circuit Breaker Keeps Tripping?
Yes. Always.
Repeated breaker tripping can indicate overheating, wiring damage, loose connections, or failing electrical components. Ignoring it increases the risk of electrical fires, shock hazards, and expensive repairs.
Your breaker is doing its job by warning you.

Electrical Panels in Colorado Homes
Many homes across Colorado, especially in Denver, Aurora, Lakewood, and Colorado Springs, were built with electrical panels that were never designed for modern power demands. Cold winters, EV charging, home offices, and newer appliances place added stress on older panels and breakers.
If you are noticing frequent breaker trips, buzzing sounds, or planning an upgrade like an EV charger or heat pump, a licensed Colorado electrician can evaluate whether your panel needs repairs or a full power upgrade.
