Why your breaker or GFCI keeps tripping

A breaker that trips once is doing its job. A breaker that keeps tripping is telling you something, and the fix depends on which kind of trip you're dealing with.
First, the safe way to reset a breaker
Find the breaker that's out of line with the others. Push it all the way to OFF first, then firmly back to ON. Many breakers won't reset if you just push them straight back. If it trips again right away, leave it off and keep reading.
Stop and call if you notice a burning smell, a breaker or panel that feels hot, buzzing or crackling, scorch marks on an outlet, or a breaker that trips the moment you reset it with nothing plugged in. Those point to a wiring problem, not a busy circuit.
The three usual causes
1. Too much on one circuit
This is the most common one. Space heaters, hair dryers, window units, microwaves, and toaster ovens pull a lot of power. Two of them on the same circuit can trip it, especially in older homes where one circuit feeds several rooms.
What to try: notice what was running when it tripped. Move one of the heavy hitters to an outlet in a different room and see if the problem stops. If you need both in the same space every day, that's a sign the room needs another circuit.
2. A short circuit
If the breaker trips instantly, even with nothing running, there may be a short: a damaged cord, a bad appliance, or a loose wire in an outlet, switch, or fixture.
What to try: unplug everything on that circuit and reset it. If it holds, plug things back in one at a time. If it trips when one particular item goes in, that item is your culprit. If it trips with everything unplugged, the problem is in the wiring, and that's a job for an electrician.
3. A ground fault
Current leaking where it shouldn't, often because of water. This is what GFCI protection is built to catch.
Why your GFCI outlet keeps tripping
GFCI outlets (the ones with TEST and RESET buttons) protect the wet areas of your home: kitchens, bathrooms, laundry areas, garages, and outdoors. They cut power fast when they sense a leak, which is what keeps a dropped hair dryer from becoming a tragedy.
- Moisture outdoors. After a hard Pee Dee rain, an outdoor outlet without a proper weatherproof cover can collect water and trip. A good "in-use" cover fixes a lot of these.
- Something plugged in is leaking current. Old freezers, pressure washers, pool pumps, and worn extension cords are common offenders. Try the outlet with nothing plugged in.
- The GFCI itself is worn out. They don't last forever. If it trips with nothing connected or won't reset at all, it may simply need replacing.
The "dead outlet" mystery
One GFCI often protects several regular outlets downstream. If a bathroom or porch outlet is dead and has no buttons, go check every GFCI in the house, including the garage, other bathrooms, and outside. One of them has probably tripped. Press RESET and the "dead" outlet usually comes back.
What not to do
- Don't keep resetting a breaker that trips right away.
- Never swap in a bigger breaker to stop the trips. The breaker is sized to protect the wire, and a bigger one can let the wire overheat inside your walls.
- Don't tape a breaker on or skip a GFCI because it's "too sensitive."
Still tripping?
I'll track down the cause and fix it right, whether it's an overloaded circuit, a bad GFCI, or a wiring problem.
