Circuit breaker keeps tripping: what it means
Quick answer
A breaker that keeps tripping is doing its job — it's protecting your wiring from too much current. The usual cause is an overloaded circuit (too many devices on one breaker), a single faulty appliance, or a short circuit or ground fault. Isolate it: unplug everything on that circuit, reset once, then add devices back one at a time until it trips again. Important: don't just keep resetting a breaker that won't hold — repeated tripping is a warning, not a nuisance.
Common causes
- An overloaded circuit — space heaters, microwaves, and hair dryers draw a lot and easily overload a shared circuit.
- A faulty appliance or device with an internal short.
- A short circuit — a hot wire touching a neutral or ground (often trips instantly and hard).
- A ground fault, especially in damp areas (handled by GFCI outlets/breakers).
- A worn-out or undersized breaker, or loose wiring in the panel.
What to check first
- Note which breaker trips and what's connected to that circuit.
- Unplug or switch off everything on the circuit, then reset the breaker once.
- Add devices back one at a time — if it trips when a specific appliance comes on, that appliance is the problem.
- If it trips with nothing plugged in, or trips the instant you reset it, stop — that suggests a short or wiring fault.
- Look and smell for any scorching, melted plastic, or heat at outlets and the panel.
When it's urgent
Treat a breaker as a smoke alarm for your wiring. Stop and call a licensed electrician right away if you smell burning, see scorch marks, feel a hot outlet or panel, or the breaker won't reset at all. Never replace a breaker with a higher-amperage one to 'stop the tripping' — that defeats the safety device and is a fire risk.
DIY vs. call a pro
You can likely DIY
- Reducing the load — moving high-draw appliances to different circuits.
- Isolating and unplugging a faulty appliance.
- Resetting the breaker once after removing the load.
Call a pro for
- Diagnosing shorts and ground faults.
- Recurring trips with no obvious overload, or a breaker that won't hold.
- Panel work, breaker replacement, and any sign of heat or burning — always licensed.

Get started freeFrequently asked questions
Is it dangerous if my breaker keeps tripping?
The tripping itself is a safety feature, but the underlying cause can be dangerous — especially a short or ground fault. If a breaker trips repeatedly, won't reset, or is accompanied by heat or a burning smell, stop using the circuit and call an electrician.
Why does my breaker trip immediately after I reset it?
An instant trip on reset usually means a hard fault — a short circuit or a ground fault — rather than a simple overload. Don't keep resetting it; that points to a wiring or appliance fault that needs a professional diagnosis.
Can I replace a breaker with a bigger one to stop it tripping?
No. The breaker is sized to protect the wire behind it. Installing a higher-amp breaker lets the wire overheat before the breaker trips — a serious fire hazard. Fix the overload or fault instead.
