Why Does My Breaker Keep Tripping? 3 Causes and What to Do
A breaker that trips is doing its job. A breaker that trips again and again is telling you something about the circuit behind it.

Cause 1: an overloaded circuit
This is the most common reason by far. A 15 amp circuit can carry about 1,800 watts. A space heater alone uses 1,500. Add a vacuum or a hair dryer on the same circuit and the breaker trips after a few seconds or minutes. Overloads follow a pattern: they happen when particular appliances run together, and the breaker resets without complaint.
The short-term fix is to move one appliance to another circuit. The lasting fix is a dedicated circuit for the heavy load. In North Dakota garages, two engine block heaters on one outlet are a classic winter overload.
Cause 2: a short circuit
A short happens when a hot wire touches a neutral or another hot wire. The breaker trips instantly, often with a pop, and it trips again the moment you reset it. Look for a scorched outlet, a damaged cord or a burning smell. Unplug everything on the circuit. If it still trips with nothing plugged in, the fault is in the wiring and you need electrical troubleshooting.
Cause 3: a ground fault
A ground fault is current leaking to ground, often through moisture. Outdoor outlets, basements, garages and bathrooms are the usual places. GFCI outlets and GFCI breakers are designed to trip on very small leaks, and that sensitivity is what protects people from shock. A GFCI that trips after rain or snowmelt points to water in a box or fixture.
Could it be the breaker itself?
Yes. Breakers wear out, especially ones that have tripped many times or run hot. Warning signs are a loose handle, a breaker that feels warm, or one that trips with almost nothing running. Replacement is quick, but the new breaker must be the type listed for your panel.
What you should never do
Do not swap in a larger breaker to stop the tripping. The breaker protects the wire in the wall, and a bigger breaker lets that wire overheat. Do not tape or hold a breaker on, either.
When to call an electrician
Call the same day if the breaker trips immediately on reset, if the panel smells hot, or if you see scorch marks. Those are jobs for an emergency electrician. If several circuits are overloaded and the panel is full, it may be time to look at an electrical panel upgrade.
