5 Reasons Your Shreveport Home Keeps Tripping Breakers (And How to Fix It)

A breaker that trips once a year during a heat wave is doing its job. A breaker that trips every time you run the microwave, or every afternoon when the AC kicks in, is telling you something. After two decades of service calls across Shreveport and Bossier City, the cause is almost always one of these five.

1. Overloaded circuit — too many things on one breaker

The most common cause, by far. A standard 15A or 20A circuit can only handle so much. When you plug a space heater, a hair dryer, and a vacuum into outlets that all trace back to one breaker, you exceed the rating and the breaker trips — exactly as designed.

How to tell: The trip happens when you turn on a specific high-draw appliance. Unplug a few things on that circuit and the problem goes away.

Fix: Move heavy appliances to a different circuit, or add a dedicated circuit. Kitchens, bathrooms, garages, and laundry rooms in particular are usually undersized in older Shreveport homes — code now requires multiple dedicated 20A circuits in each of those rooms.

2. Short circuit — hot wire touching neutral or ground

A short happens when a damaged wire's hot conductor touches the neutral or the grounded metal box. Current spikes instantly and the breaker trips hard.

How to tell: The breaker trips immediately when you turn on a specific switch or plug in a specific appliance. Sometimes there's a snap or a flash at the receptacle. Sometimes you smell burnt plastic.

Fix: This is not a DIY situation. The damaged wire, receptacle, or appliance has to be found and replaced. If you see scorching on a receptacle face, stop using it and call.

3. Ground fault — hot conductor touching ground (GFCI trips)

A ground fault is similar to a short, but specifically a hot-to-ground leak. In bathrooms, kitchens, garages, exteriors, and anywhere within 6 ft of a sink, code requires GFCI protection — and GFCIs trip on as little as 5 milliamps of leakage.

How to tell: A GFCI receptacle's TEST/RESET button popped out, or a GFCI breaker is in the tripped position. Often happens after rain on exterior outlets or when an old refrigerator's compressor starts.

Fix: Reset the GFCI. If it trips again immediately, you have a real ground fault — usually a failing appliance, a wet outlet box, or moisture in an exterior conduit. If it holds, you're fine. GFCI devices themselves also wear out (typical lifespan 10–15 years) and should be replaced if they trip nuisance-style.

4. Arc fault — damaged wiring sparking inside walls (AFCI trips)

AFCI breakers detect the high-frequency signature of an electrical arc — a wire sparking against itself, against a staple, or at a loose terminal. They're code- required in most habitable rooms since 2014, and they catch problems that would otherwise smolder for months before starting a fire.

How to tell: A breaker labeled "AFCI" or "CAFCI" trips, often seemingly at random. Sometimes triggered by motor-driven appliances (vacuums, drills) that produce arc-like signatures.

Fix: First, try unplugging the motor-driven device — some older vacuums and treadmills nuisance-trip AFCIs. If the trip persists, you have real arcing somewhere in the circuit and an electrician needs to locate it. Do not replace the AFCI with a standard breaker — that's defeating a safety device that's almost certainly catching a real problem.

5. Failing breaker — the breaker itself is bad

Breakers are mechanical devices. They wear out. After 25–40 years of normal cycling — and especially in panels exposed to humidity, like Louisiana garages without conditioned air — the thermal element drifts and a breaker starts tripping below its rating.

How to tell: The circuit's actual load is well below the breaker's rating (verified with a clamp meter) but it still trips. Often happens in older Federal Pacific, Zinsco, or original Square D QO panels from the 1970s.

Fix: Replace the breaker. If multiple breakers in the same panel are failing, or the panel is a known-bad brand, replace the whole panel — see our warning signs guide for what to look for.

When tripping breakers become an emergency

Stop using the circuit and call right away if you see any of these:

• Burning smell coming from the panel or any receptacle
• The panel cover is warm to the touch
• Scorch marks or discoloration around a breaker or outlet
• A breaker that won't reset, or that resets and trips again instantly
• Buzzing, crackling, or sizzling sounds from the panel
