Tripping Breakers: When to Call a Nashville Electrician

Troubleshooting Nashville Electric Pros · Updated May 2026

A breaker trip is the electrical system doing its job — interrupting current to prevent something worse. But repeated trips mean something is wrong. Here's how to read what your breaker is telling you.

When a breaker trips, it's responding to one of three things: too much current (overload), a short circuit, or a ground fault. Understanding which one matters, because the response is different for each.

Overload Trips

The most common kind. You plugged a space heater into the same circuit that already powers a microwave, hair dryer, or vacuum. The total current exceeded the breaker rating, and it tripped.

What to do: Unplug the load that pushed it over, wait a moment, reset the breaker, and rearrange your devices across different circuits. Single occurrence, single cause = no electrician needed.

Short Circuit Trips

A short circuit happens when hot and neutral (or hot and ground) accidentally make contact, causing a massive current surge that trips the breaker immediately and forcefully. Shorts are commonly caused by:

• A damaged appliance cord
• A damaged outlet or switch
• A nail or screw driven through a hidden wire
• Failing wire insulation

What to do: Unplug everything on the circuit, then try to reset the breaker. If it stays on, the issue was with something you unplugged — inspect each item. If it trips again with nothing plugged in, the wiring itself has a fault and needs a Nashville electrician immediately.

Ground Fault Trips

A ground fault is when current finds an unintended path to ground — often through a person or a wet surface. GFCI breakers and GFCI receptacles specifically detect these and trip very quickly (milliseconds).

What to do: Test/reset the GFCI. If it trips again, look for the cause: moisture in an outdoor outlet, a wet appliance, damp insulation in a bathroom fixture. Persistent ground faults need investigation.

Signs It's the Breaker Itself

Breakers wear out. Signs that a specific breaker is failing:

• It trips even with very small loads
• It feels loose in the panel
• It's discolored, scorched, or melted-looking
• The handle won't fully reset (won't snap to the "off" position before turning back on)
• Buzzing or humming from inside the panel

When to Call a Nashville Electrician Right Away

• Burning smell from the panel, an outlet, or a switch
• Scorch marks on any device
• A breaker that trips repeatedly even with nothing plugged in
• A breaker that won't reset at all
• The panel itself feels warm
• You hear arcing, buzzing, or popping inside the panel
• Multiple breakers trip simultaneously

Federal Pacific, Zinsco, and Pushmatic Panels

If your home has one of these older panel brands, "tripping breakers" carries extra weight. These panels have documented failure modes where breakers fail to trip when they should, or trip unpredictably. If you have one and it's misbehaving, the right answer is usually panel replacement.

What Not to Do

• Don't replace a 15A breaker with a 20A to "fix" trips — the wire is sized for 15A, and the larger breaker is now a fire risk
• Don't tape a breaker in the "on" position
• Don't ignore repeated trips on the same circuit
• Don't open the panel's dead front cover yourself unless you're trained

The Pattern Tells the Story

When you call a Nashville electrician about tripping breakers, the most useful information you can share is the pattern: which breaker, when, and what was happening at the moment. That pattern almost always points directly to the cause.
