Why Your Breaker Keeps Tripping (and What Not to Do About It)
A tripping breaker is doing its job. Here's how to figure out whether it's an overload, a short, a ground fault, or a dying breaker — and why swapping in a bigger breaker is how house fires start.
A breaker that trips is a breaker that's working. It's cutting power because the circuit pulled more current than the wire can safely carry — or because current is going somewhere it shouldn't. The goal isn't to stop the tripping. It's to find what's causing it.
The four causes, in order of how often we see them
- Overload — too much stuff on one circuit. Space heaters, window ACs, and hair dryers are the classics. Trips after a few minutes of use, not instantly.
- Short circuit — hot touches neutral or ground. Trips instantly, often with a pop, and may trip again the second you reset it.
- Ground fault — current leaking to ground, usually moisture. Common in kitchens, baths, basements, and outdoor outlets.
- A dying breaker — the breaker itself is worn out. Common on panels 30+ years old, and very common on Federal Pacific and Zinsco panels.
The 10-minute test you can do yourself
Unplug everything on the dead circuit. Reset the breaker (push it fully to OFF first, then ON). If it holds, plug things back in one at a time, a minute apart. The device that trips it is your answer — or you have an overload and that circuit is simply carrying too much. If it trips instantly with nothing plugged in, stop. That's a wiring fault, and it needs an electrician.
Never, ever swap a 15-amp breaker for a 20-amp 'to stop the nuisance trips.' The breaker is sized to the wire in your walls. Upsizing it means the wire overheats inside the wall with nothing to stop it. This is one of the most common fire-starters we find in older Baltimore homes.
When it's the panel, not the circuit
If the breaker won't reset at all, feels mushy, smells hot, or the panel is a Federal Pacific Stab-Lok or Zinsco, the breaker may no longer trip when it should. That's worse than nuisance tripping — it's no protection at all. Those panels get replaced, not repaired.
What a proper fix looks like
- Overload on a bedroom or kitchen circuit: add a dedicated circuit, $350–$900
- Faulty breaker or worn panel connection: $150–$350
- Dead panel: replacement, $2,400–$4,800, permitted and inspected
