Breaker Keeps Tripping
A breaker that keeps tripping is usually trying to protect the circuit from overload, a fault, or a wiring problem that should not be ignored.
Quick Answer
A tripping breaker is usually doing its job. The most common causes are too much load on one circuit, a faulty appliance, or a short or ground fault somewhere on the line.
Common Causes
- Too many devices or appliances may be running on the same circuit at the same time.
- One appliance could be faulty and trip the breaker as soon as it turns on.
- A short circuit or ground fault may be present in wiring, a receptacle, a switch, or a connected device.
- The breaker itself could be worn or weak, especially if the same circuit has had years of repeated trips.
What to Check First
- Turn off or unplug recently added loads, then reset the breaker fully and see whether it holds.
- If the breaker trips when a specific appliance starts, unplug that appliance and test the circuit again without it.
- Check whether the trip happens only at busy times, which may point to overload instead of a hard fault.
- Look for obvious warning signs such as scorch marks, heat, or damage at receptacles and switches on that circuit without removing covers.
Quick summary
A tripping breaker is usually doing its job. The most common causes are too much load on one circuit, a faulty appliance, or a short or ground fault somewhere on the line. If it trips immediately or trips when an appliance turns on, the pattern can help narrow the cause.

A multimeter can help narrow down whether a circuit is actually carrying power where you expect it, while a voltage tester is a safer first check before touching anything.

When to call an electrician
- Stop if the breaker trips immediately after reset or trips with nothing plugged in.
- Stop if you notice a burning smell, buzzing, heat, or visible damage anywhere on the circuit.
- Call a licensed electrician if you cannot identify a simple overload or if the same breaker continues tripping repeatedly.
Still not sure what's causing it?
If the problem keeps happening, feels unsafe, or you're not comfortable checking it further, it may be time to talk to a licensed electrician.
