A breaker that keeps tripping is working correctly and reporting a real condition. Reset it once. If it trips again, stop. Repeated resets against a live fault degrade the mechanism, which is how a breaker later fails to trip when it matters.

## Reset once. Not twice.

A circuit breaker is a sacrificial safety device with a finite number of fault
interruptions in it. Each reset against a live fault stresses the mechanism. The
failure you are working toward is a breaker that no longer trips at all, which
removes the only protection that circuit has.

If it trips again immediately after one reset, leave it off and find out why.

## The four causes, and how to tell them apart

**Overload.** The circuit is carrying more current than it is rated for. The
signature is timing: it holds for a while, then trips when one more thing
switches on. In Boise the seasonal versions are a space heater added to a
general lighting circuit in winter, and a window unit or a second refrigerator
in the garage in summer. The fix is a dedicated circuit, not a bigger breaker.

**Short circuit.** A hot conductor touching neutral or ground. The signature is
instant and repeatable: it trips the moment you reset, with nothing switched on.
Often accompanied by a scorch mark or a smell. Stop and call.

**Ground fault.** Current leaking to ground, usually through moisture. Trips a
GFCI rather than a standard breaker. Here it shows up seasonally on exterior,
garage and irrigation-adjacent circuits rather than year-round.

**Arc fault.** An AFCI breaker trips on the electrical signature of arcing
rather than on current. In older North End and Bench housing these trips are
frequently correct — an AFCI can detect a deteriorating connection long before
it is hot enough to notice. Do not replace an AFCI with a standard breaker to
make the tripping stop. That is removing the smoke detector because it beeped.

## What you can safely check yourself

1. **Unplug everything on the circuit**, then reset. If it holds, add devices
   back one at a time. A failing appliance is the cause more often than the
   wiring.
2. **Check every GFCI in the house** — garage, exterior, bathrooms, and any in
   the panel. One tripped GFCI can kill outlets in rooms nowhere near it.
3. **Note whether it trips under load or at rest.** Under load points to
   overload. At rest points to a short or ground fault.
4. **Look for the obvious**: a damaged cord, a wet exterior outlet, a recent
   nail or screw into a wall.

## Stop and call now if any of these are true

- A burning, hot-plastic or fishy smell near the panel or an outlet
- Any warmth or discoloration on a faceplate, switch or receptacle
- Buzzing, humming, crackling or ticking from the panel
- Visible scorching
- The breaker trips instantly and repeatably with nothing plugged in
- The **main** breaker is what is tripping
- Water anywhere near the panel

Those are not book-it-next-week conditions.

## Why it might be seasonal

Two Boise-specific patterns worth knowing. If it only trips in July, the cause
is usually air conditioning: a condenser's starting inrush is several times its
running current, and on a circuit near capacity that inrush is what tips it. If
it only started after a heat pump conversion, the electric resistance backup
heat is a genuinely large load that was never in the original calculation, and
the answer is a load calculation rather than a bigger breaker.

## Bottom line

The breaker is not the problem; it is the messenger. Reset once, work through
the checks above, and never fit a larger breaker to stop the tripping — the wire
behind it did not get any bigger. If it trips a second time or anything on the
stop-and-call list is true, call 208-856-4826.

## FAQ

### Can I just put in a bigger breaker?
No. The conductor behind that breaker is sized for the original rating. A larger breaker lets the wire carry more current than it is rated for without tripping, which is precisely the condition breakers exist to prevent. It is a common and genuine cause of wall fires.

### Why does it only trip in summer?
Air conditioning. A condenser's starting inrush is several times its running current, and on a circuit already near capacity that inrush is what tips it over. It is a real overload, and the fix is usually a dedicated circuit or a capacity review.

### My AFCI trips but nothing seems wrong. Can I swap it?
Do not. An AFCI detects the signature of arcing, which means it can find a deteriorating connection well before there is anything to see or smell. In older housing those trips are frequently correct and worth tracing.
