The Short Answer

Why Breakers Trip in the First Place

A circuit breaker has one job: cut power when something goes wrong. When it trips, the internal mechanism detects more current flowing through the wire than that circuit was designed to handle. The breaker flips to the off position to stop that flow before the wire overheats.

There are three main reasons this happens, and they are not equally serious.

Overloaded Circuits

This is the most common cause and the least alarming — at first. You plug a space heater into the same outlet strip as your computer and monitor, and suddenly the kitchen or bedroom circuit flips. Circuit overloads happen when the total wattage demand exceeds what that circuit’s breaker is rated for, typically 15 or 20 amps in residential wiring.

The fix might be as simple as redistributing appliances to different circuits. But if your home has older wiring where too many devices share too few circuits, you’re running into a structural problem that unplugging things won’t permanently solve. An electrical panel upgrade or additional circuit installation may be the right answer.

Short Circuits and Ground Faults

A short circuit happens when a hot wire touches a neutral wire. A ground fault happens when a hot wire contacts a grounded surface. Both cause an immediate, dramatic spike in current — the kind that trips a breaker fast. These are more serious than a simple overload.

Signs of a short or ground fault include a burning smell near outlets, discolored outlet covers, or a breaker that trips the instant you reset it. Don’t keep resetting a breaker that behaves this way. That’s the electrical system doing exactly what it’s supposed to do, and overriding it manually creates genuine danger.

A Weak or Failing Breaker

Breakers aren’t designed to last forever. After years of trips and resets, the internal mechanism can wear down. A failing breaker might trip under loads it should handle easily, or it may not trip when it actually should — which is arguably the scarier scenario. If your breaker feels warm to the touch, won’t stay reset, or the panel is more than 25 years old, it deserves a look from a licensed electrician. Reed Electrical Services works throughout Palos Hills and the surrounding southwest suburbs and can assess whether the panel itself is the problem.

What You Should (and Shouldn’t) Do

Safe Steps When a Breaker Trips

First, unplug or turn off devices on that circuit before you reset anything. Then go to your panel, find the tripped breaker (it’ll sit between ON and OFF, or be fully flipped to OFF), and push it firmly to OFF before switching it back to ON. If it holds, you’re likely dealing with a temporary overload. Spread your devices across multiple circuits and monitor it.

If it trips again within a short period or immediately on reset, stop. That’s the point where a professional electrical inspection in the area makes sense. Trying to force a breaker that keeps tripping is how electrical fires start.

When to Call an Electrician

Call a licensed electrician if you notice any of these situations: the breaker trips repeatedly with normal loads, you smell burning near the panel or outlets, the breaker feels hot, or the panel itself shows signs of rust, scorch marks, or buzzing sounds. These aren’t inconveniences — they’re warnings. Licensed electricians in Illinois are required to follow the National Electrical Code, and for good reason. The National Fire Protection Association’s NFPA 70 sets the standards that keep residential wiring safe, and those rules exist because electrical fires cause thousands of home losses every year.

Local residents in the southwest Chicago suburbs can also check the State of Illinois official site for licensing verification resources to confirm any electrician they hire is properly credentialed.
