Circuit breaker problems in Centennial homes most often fall into three categories: the circuit is overloaded for its rated amperage, the breaker itself has failed and is tripping prematurely or not holding correctly, or there is a wiring fault on the circuit that is causing the breaker to trip for a legitimate protection reason. Each of these requires a different repair, and a proper diagnosis is the only way to know which one you are dealing with.

Breaker repair sometimes reveals the need for broader panel work. Our electrical panels team handles panel upgrades and replacements when the panel itself is the issue. For wiring faults that are causing breaker trips, our electrical wiring team addresses the circuit condition. See all Centennial electrical services.

• Repeatedly tripping breakers diagnosed to identify whether the cause is circuit overload, a failing breaker, or a wiring fault on the circuit.
• Breakers that will not reset, which usually indicates a persistent fault on the circuit that needs to be cleared before the breaker will hold.
• Breakers that feel hot or emit a burning smell, which require immediate evaluation as these indicate a potentially dangerous condition.
• GFCI or AFCI breaker trips traced to find the specific fault or device triggering the protection circuit.
• Single breaker replacement when the breaker itself has failed or is tripping below its rated threshold.

Here are the circuit breaker repair situations our Centennial electricians handle most often.

What Does It Mean When a Breaker Will Not Stay Reset?

A breaker that trips immediately when reset or will not hold after resetting has a persistent fault on the circuit that is causing the breaker to trip again as soon as current flows. This is the breaker doing exactly what it is designed to do: protecting the circuit from a condition that would cause damage or danger. Common causes include a dead short somewhere on the circuit wiring, a failed appliance or device plugged into the circuit, or a ground fault at an outlet or in the wiring itself.

Unplug all devices from the circuit before attempting to reset the breaker. If it holds with everything unplugged, plug devices back in one at a time to find which one is causing the fault. If the breaker trips with nothing plugged in, the fault is in the wiring or outlet itself, and WireNut should evaluate it before you use the circuit again.

Can a Circuit Breaker Fail Without Tripping?

Yes, and this is actually the more dangerous failure mode. A breaker that trips correctly when overloaded is functioning as designed. A breaker that has aged to the point where it does not trip when it should allows a circuit to carry more current than it is rated for, which overheats the wiring and creates a fire risk. This type of failure does not announce itself with trips or symptoms until something more serious occurs.

Breakers in Centennial homes from the 1980s and earlier are old enough that this kind of degradation is plausible. If you have concerns about breakers that seem to tolerate heavier loads than they should without tripping, WireNut can test them and give you an honest assessment of their condition.
