That breaker didn't trip by accident. It tripped to warn you, and most people ignore it. The move: check for danger, unplug what was running, then reset it once. Just once. If it trips again, leave it off and call an electrician. No second tries. But the step that matters most happens before you even touch the panel. Most people skip it. 6 moves, in this order. Each one's there for a reason, so skip none.

Step 1: burning smell, smoke, scorch marks, a warm or buzzing outlet? Leave it off. Call an electrician. Step 2: unplug or switch off what was running on that circuit. Heaters and kettles first. Step 3: one dead outlet? Find a GFCI in a bathroom, the kitchen, the garage or outside. Press RESET. Step 4, at the panel: make sure your hands are dry, and stand off to one side. Push the tripped breaker firmly, all the way to OFF, then back to ON.

Do it once. Step 5: it trips again right away, or keeps tripping for days? Stop resetting. Call a licensed electrician. Step 6: fewer plugs on that circuit, heaters on another, and learn which outlets sit on which breaker. Here's the instinct: a trip is just a nuisance. Flip it back on, carry on with dinner. Wrong. The Consumer Product Safety Commission says a trip is often a warning that the circuit is overloaded.

Their advice is blunt: find out why it tripped. Don't just reset it and walk away. And here's the part nobody tells you: a breaker that hasn't tripped doesn't prove you're fine. Why it trips: too many appliances plugged in, a product that's malfunctioning, or a short circuit. Heat is the hog. Several heating appliances on one low-amperage circuit is exactly what the CPSC warns against. NFPA's example: an extension cord running several appliances on a 20-amp circuit can overload without ever tripping.

Now the dead outlet. Often it isn't broken. A GFCI somewhere else, maybe another room, cut it. GFCIs cut a circuit that becomes a shock hazard. A porch one can guard the back of the house. But what if it trips again the second you flip it back on? Leave it off. That can mean a short. Repeated resets risk an arc flash or a fire. GFCI won't stay reset, or won't cut out when you press TEST? It needs replacing.

Call a licensed electrician. Panel wet, or a burning, rubbery smell? Don't touch it. Call an electrician or your landlord. GFCIs can fail without any sign. Test monthly: nightlight in, press TEST, it goes out. RESET, it's back. The takeaway: check for danger, unplug the load, reset once, and find out why. Test your GFCIs every month, and if your home is 40 years or older, get it inspected. A breaker that trips once is a warning.

One that trips twice is a phone call.
