What Causes Circuit Breakers to Keep Tripping?
By Soundside ElectricalMarch 4, 2025Updated July 31, 20255 min read
A circuit breaker that keeps tripping is protecting you from an overload or a fault. The trip is the symptom — the cause is what matters. Here's what usually makes a breaker trip and what to do about each cause.
The Most Common Causes
An overloaded circuit is the most common cause: too many devices drawing too much current on one circuit. The breaker trips to keep the wire from overheating. The fix is moving loads to other circuits or adding a dedicated circuit for high-draw devices.
A short circuit — when a hot wire touches a neutral or ground wire — causes an immediate trip. Shorts can come from damaged wire, a failed device, or a loose connection. This needs diagnosis and repair.
A ground fault — current leaking to ground, often through water or a damaged device — also trips a breaker (or a GFCI). Common in kitchens, baths, and outdoors.
A failing breaker can also trip repeatedly. Breakers wear out, and a breaker that trips with no apparent load may simply be failed.
What to Do When a Breaker Trips
Reset a tripped breaker once. If it trips again immediately, don't keep resetting it — it's protecting you from a fault. Unplug everything on the circuit, reset, and if it still trips with nothing plugged in, call an electrician.
If it holds with everything unplugged but trips when you plug something back in, the device is likely the cause. If it trips with multiple devices but not one alone, the circuit is overloaded.

Frequently Asked Questions
The most common causes are an overloaded circuit (too much on one circuit), a short circuit (damaged wire or device), a ground fault (current leaking to ground), or a failing breaker. A diagnosis identifies the specific cause.
Reset once. If it trips again, stop — it's protecting you from a fault. Repeatedly resetting a tripping breaker can be dangerous. Call an electrician to find the cause.
Yes. Breakers wear out and can trip with no real load. If a breaker trips with nothing on the circuit, the breaker may be failed and need replacement.
