Understanding Circuit Breaker Trips
Circuit breakers are safety devices designed to protect your home's electrical system by shutting off power when an issue arises.
Common Reasons Your Breaker Keeps Tripping
Overloaded Circuits
Too many devices running on one circuit can cause it to overload and trip.
Short Circuits
A wiring fault causes current to flow along an unintended path, resulting in a trip.
Ground Faults
When electricity flows through an unintended path to the ground, it triggers the breaker.
Faulty Appliances or Devices
Defective appliances can cause breakers to trip frequently.
Aging or Faulty Breaker
Breakers can wear out over time and may need replacement.
How to Troubleshoot a Tripping Breaker
- Identify the circuit and devices causing the issue.
- Unplug or turn off appliances on that circuit.
- Reset the breaker and test.
- If the breaker trips again, call a licensed electrician.
Comparison Table: Breaker Trip Causes and Solutions
| Cause | Symptoms | DIY Fix Possible? | When to Call a Professional |
| Overloaded Circuit | Breaker trips under heavy load | Yes (reduce load) | If frequent or unsure |
| Short Circuit | Immediate breaker trip | No | Immediate electrician needed |
| Ground Fault | Breaker trips when the device is used | No | Call an electrician right away |
| Faulty Appliance | Trips when a specific device is on | Yes (unplug device) | Replace or repair the appliance |
| Faulty Breaker | Breaker trips randomly | No | Electrician to replace a breaker |
Advanced Causes of Breaker Trips You Might Overlook
While common issues like overloaded circuits are easy to understand, some tripping causes are more subtle and harder to detect. These advanced electrical conditions may require professional inspection and specialized tools to identify.
Arc Faults
Arc faults occur when electricity jumps across a gap in a damaged wire, which can lead to overheating and fire risk. Arc fault circuit interrupters (AFCIs) are designed to detect these faults and shut off power. If your home doesn’t have AFCIs or they are tripping often, you may need to upgrade or replace outdated wiring.
Electrical Panel Limitations
Older panels may not support the number of appliances and high-wattage devices modern homes use. If your panel is outdated or undersized, it may trip due to capacity issues, even if no specific fault exists. Excel Electric offers panel assessments and breaker replacement cost estimates so you can plan for an upgrade.
Improper Wiring or DIY Installations
Poorly executed electrical work, including unlicensed DIY installations, can cause frequent breaker trips. Common issues include double-tapped breakers, improperly grounded circuits, and mismatched wire gauge. These violations increase fire risk and disrupt circuit stability.
Intermittent Ground Faults
Some ground faults are not constant but occur only under certain environmental conditions, like humidity or after rain. These may be linked to outdoor outlets, underground wiring, or improperly sealed junction boxes. Excel Electric performs thermal imaging and ground fault testing to detect hard-to-find culprits.
Shared Neutral Wiring Errors
Some older homes have multiple circuits sharing a neutral wire. If incorrectly wired, this setup can confuse the breaker and cause frequent trips, especially with modern AFCI breakers. Our electricians can trace and separate shared neutrals during system reconfiguration.
Specialized Diagnostic Tools Excel Electric Uses
To identify elusive problems behind circuit breaker trips, our team uses advanced tools, including:
- Clamp meters to detect current draw and spikes
- Infrared cameras for detecting heat buildup in panels and outlets
- Megohmmeters for insulation resistance testing
- Circuit analyzers to map loads and detect harmonics
These tools help us provide more accurate electrical breaker repair that Longmont homeowners can count on.

Long-Term Prevention Tips for Avoiding Breaker Trips
Solving a tripping breaker once is helpful, but preventing future problems is even better. Here are strategies homeowners can use to maintain a stable electrical system year-round.
1. Perform Regular Load Checks
Use a circuit load calculator or contact a professional to measure how much power your appliances draw. Spreading out devices across multiple circuits reduces overloads.
2. Replace Aging Appliances
Old refrigerators, heaters, or microwaves can become unstable over time, causing the breaker to keep tripping, and issues to arise repeatedly. Upgrading to newer, energy-efficient models helps protect your system.
3. Schedule Annual Panel Inspections
A yearly panel check-up from a licensed electrician in Longmont, CO ensures terminals are tight, breakers are functional, and no signs of corrosion or arcing are present.
4. Upgrade Outdated Panels and Wiring
Many homes in Longmont still operate on fuse boxes or outdated panels. If your home’s electrical system hasn’t been updated in 30+ years, it may not support modern electrical loads. An upgrade significantly reduces circuit breaker trips frequently.
5. Install Surge Protection
Whole-home surge protectors prevent voltage spikes from damaging sensitive equipment and causing nuisance tripping. Excel Electric offers installation services that safeguard your home long-term.
6. Add AFCI and GFCI Protection Where Needed
If you’re tripping a breaker near bedrooms, kitchens, or outdoor areas, modern AFCI or GFCI outlets may be the solution. These specialized protections enhance safety and reduce trips from unseen hazards.
7. Label Every Breaker Clearly
Many tripping issues are made worse by confusion at the panel. Properly labeling each breaker helps isolate issues quickly during emergencies or when performing troubleshooting.
Educational Tip: How to Use Your Breaker Panel Safely
Understanding your panel gives you more control over your home’s electrical health.
- Know where your main breaker is — this shuts off all power to your home.
- Flip breakers off before resetting a tripped one.
- Don’t force a breaker to stay on. If it trips again, call for professional help.
- Keep your panel accessible and clear of obstructions.
A clean, organized panel labeled by a professional electrician ensures peace of mind and reduces risk.
