Circuit Breaker Keeps Tripping in Orlando, FL
A breaker that trips once has done its job. One that keeps tripping is telling you about the circuit behind it, and the timing usually says what: only under load, only after a storm, only when one appliance starts. Thomas Edison Electric traces tripping breakers and failing panels across Orlando, Winter Park, and the Seminole County suburbs.

What the Breaker Is Protecting
A breaker guards the wire inside your walls, not the appliance you plugged in. It opens when current exceeds what the wire can carry.
- Overload. Too many things pulling at once on a circuit built for less. The breaker warms up first, so it holds a minute of hard use, then drops.
- Short circuit. A hot conductor touching a neutral or a grounded part, often a damaged cord or a nail through a cable. It trips instantly.
- Arc fault. Electricity crossing a gap rather than flowing through metal, at a loose terminal screw or a pinched cord. It burns hot on very little current, the reason AFCI protection exists.
- Ground fault. Current finding a path out of the circuit. Against a grounded surface it can spike high enough to open a standard breaker outright. The quieter version, a small leak through moisture or failing insulation, takes a GFCI to catch.
Timing Is the Best Clue You Have
The clock tells you more than the panel does.
- It goes when the pool pump, well pump, or air handler starts. Motors surge at startup, and a worn one surges longer than the circuit can absorb.
- It holds a few minutes, then drops under heavy use. A true overload, usually a bedroom circuit that became a home office.
- It goes after a storm, or once irrigation has run. A GFCI that keeps tripping outdoors is usually catching water in a box, a lanai fixture, or pool equipment.
- It will not stay on with everything unplugged. Nothing you own is causing this. Suspect the cable in the wall, a hardwired fixture, or the breaker.
- It trips more easily than it used to. Breakers have a finite life, and one that has aged out lets go at loads it once carried.
Three Jobs: Overload, Leakage, and Arcing
A standard breaker watches current only: a sustained overload or a dead short. A GFCI compares current out against current back and opens on a mismatch far too small for a standard breaker to see, which protects someone barefoot on a wet lanai. NEC 210.8 sets out where it is required: kitchens, bathrooms, garages, laundry areas, and outdoor receptacles. An AFCI reads the circuit signature and opens on arcing, preventing fires rather than shocks; NEC 210.12 covers bedrooms and other living areas. Adoption in Florida runs through the Florida Building Code, so what governs a circuit depends on when the work was permitted.
What Happens Each Time You Reset It
Every reset sends full current straight back into whatever opened the breaker. If that is a loose connection or an arcing splice inside a wall, you are re-energizing a spot already making heat, and the panel face will not show it. A breaker also holds a limited number of operations, and a breaker that has been reset dozens of times may fail to trip when it needs to. The risk runs higher in panels with documented reliability problems, including Federal Pacific Stab-Lok and Zinsco equipment, still common in Winter Park and Seminole County.
When Whole Rooms Go Dead and the Panel Looks Fine
This is not a troubleshooting exercise. Two 120-volt legs feed the panel, and every circuit hangs off one or the other. Lose a leg at the meter, in the service conductors, or at the main breaker, and everything on it goes dead while the rest of the house runs normally. A failed neutral is worse: the halves stop sharing voltage evenly, so rooms on one side glow unusually bright while others go dim, and sensitive electronics can be ruined quickly. Unplug computers and televisions if you safely can, keep the panel cover on, and call for emergency service. The fault may sit in your service equipment or on the utility side, which in this area is usually Duke Energy Florida or OUC, though the City of Winter Park runs its own municipal electric utility.
Before You Touch the Panel
Leave the breaker off and call for emergency service if any of this is true:
- Water has reached the panel, an outlet, or a light fixture.
- Scorch marks, brown discoloration, or melted plastic at an outlet, a switch, or a breaker.
- A burning plastic smell at an outlet, a switch, or the panel, even faint.
- A warm breaker or cover plate, or buzzing and crackling from the panel or a wall.
- With every load unplugged, the breaker still will not hold.
If none of that applies, these are safe:
- Write down which rooms and outlets went out; that map is the most useful thing you can hand an electrician.
- Clear the circuit, then cycle the handle fully off before switching it back on; one resting in the middle re-energizes nothing. Do that once, then restore loads one at a time.
- Check for a GFCI with its reset button popped out, in the garage, a bathroom, the laundry, or outside. One protected receptacle often feeds a string of ordinary outlets, so a back-bedroom outlet can revive from a button elsewhere.
Never remove the panel cover, and never tape, wedge, or upsize a breaker.
How Thomas Edison Electric Traces a Tripping Breaker
Our licensed electricians (Florida electrical contractor license EC13015487) start where the evidence is. We confirm what the circuit feeds, measure load and voltage under real conditions, and separate a genuine fault from a circuit that simply needs a dedicated run. We inspect terminations at the panel and at devices on the circuit, because loose screws and backstabbed connections cause most arcing and intermittent trips. We test the breaker and check the panel for heat damage, corrosion, double taps, and the clear working space NEC 110.26 requires.
A Central Florida Angle
Humidity and summer storms make ground faults seasonal here. Outdoor boxes, lanai circuits, and pool equipment take on moisture, and the first symptom is often a breaker that trips the morning after a storm and behaves once things dry out. Lightning can degrade a breaker or an appliance control board without destroying it, so the trips start weeks later. Mid-century homes in Winter Park, Maitland, and older parts of Sanford were wired for a fraction of today’s load, and some 1960s and 1970s houses have aluminum branch wiring, where connections loosen and arc.

Frequently Asked Questions
Why does my breaker trip when I plug in a space heater or hair dryer?
Those appliances use most of a standard circuit by themselves, so anything else running pushes the total past the rating. Try it on another circuit; if it trips there too, blame the appliance.
My circuit is overloaded. What is the actual fix?
More circuit, not more breaker. A breaker rating is matched to the gauge of the cable it feeds, so a larger one strips that cable’s protection and lets it heat inside a wall. The heavy load needs its own run.
Why does my AFCI breaker trip when nothing seems wrong?
Some motors, dimmers, and older electronics produce a signature close to arcing, and two circuits sharing a neutral will trip them too. Take it seriously anyway: an AFCI looks for damaged connections that start fires.
Why does my breaker only trip at night?
Look at what runs on a timer. Pool pumps, irrigation controllers, and water heaters are often scheduled overnight, and a circuit that is fine all afternoon gets pushed past its limit when one starts.
A breaker that keeps tripping is a warning worth acting on. Call Thomas Edison Electric at (407) 490-0004 for 24/7 emergency service, schedule a diagnostic visit, or read how we trace faults for Orlando-area homeowners.
