Why Your Breaker Keeps Tripping (And What It Usually Means)
If a circuit breaker keeps tripping, it’s doing its job: cutting power when something isn’t right. The key is figuring out whether it’s a simple overload (common) or a fault/connection issue (more serious). This guide explains the most common causes in plain language — no DIY wiring instructions — so you know what’s normal, what’s not, and when to call a licensed electrician.
If this is happening along with other electrical symptoms, start with 10 Electrical Warning Signs You Should Never Ignore to see whether your home may have a larger safety issue.
Quick answer
A breaker usually trips for one of three reasons: overload (too many things on one circuit), short circuit (hot touching neutral/ground), or ground fault (electricity flowing where it shouldn’t). Repeated tripping is a warning sign that should be diagnosed.
The 3 most common reasons breakers trip
1) Overloaded circuit (most common)
- Space heater + hair dryer + bathroom outlet → trip
- Microwave + air fryer + toaster oven → trip
- Garage tools + shop vac → trip
Overloads are usually a capacity issue, not a mystery.
If you’re noticing warmth at an outlet during heavy use (but it’s not hot), read Is It Normal for an Outlet to Feel Warm? to understand what’s normal vs. a warning sign.
2) Short circuit (more serious)
- Trips immediately when a device turns on
- May include a pop, spark, or burnt smell
- Often caused by damaged cords, failed appliances, or wiring issues
3) Ground fault (often tied to moisture or damage)
Ground faults are common in kitchens, baths, garages, outdoors, basements, and laundry areas. If tripping seems tied to humidity, rain, a wet area, or outdoor use, treat it as a serious safety concern.
Safe homeowner checks (no tools required)
- Write down what was running when it tripped (heater, microwave, dryer, tools, etc.).
- Unplug the newest device added to that circuit and see if the issue stops.
- Reduce load: move high-watt items to other circuits (if available).
- If it trips instantly again, stop resetting and call a licensed electrician.
When the “fix” is actually an upgrade
If a breaker trips regularly in normal use, the real solution is often one of these:
- Dedicated circuits for high-use areas (kitchen appliances, home office, garage tools)
- Repairing loose connections (which can create heat and arcing)
- Replacing worn outlets or switches that no longer hold plugs firmly
- Evaluating panel capacity if the home’s electrical demand has outgrown the service

Is it normal for a breaker to trip sometimes?
Occasional trips can happen with an overload or a device problem. Repeated tripping is a warning sign and should be investigated.
What is the most common reason a breaker keeps tripping?
Overload. Too many high-watt items running on the same circuit (heaters, kitchen appliances, tools) is the most common cause.
When should I call an electrician for a tripping breaker?
Call if it trips repeatedly, won’t reset, trips under light load, or you notice burning smells, heat at outlets/panel, buzzing, or discoloration.
Can a breaker trip because of a bad outlet or loose connection?
Yes. Loose connections and failing devices can cause heat/arcing or fault conditions that trip breakers—and can be hazardous.
