You need a licensed electrician to replace a circuit breaker safely
Circuit breakers are live electrical components inside your main panel, and working on them carries serious risk of electrocution or arc flash even if the main breaker is off. Most jurisdictions require a licensed electrician to replace a breaker, and many building codes prohibit homeowners from doing this work themselves. If your breaker has tripped repeatedly, won't reset, or is visibly damaged, contact a licensed electrician rather than attempting the repair yourself.
The cost of hiring an electrician to replace a single breaker typically ranges from $150 to $300 for the service call plus the breaker itself, though this varies by region and whether the electrician needs to troubleshoot why the breaker failed. Some homeowners' insurance policies cover electrical repairs, so check your policy before paying out of pocket.
Key Takeaways
- Circuit breaker replacement requires a licensed electrician in most places because the work involves live electrical components inside your main panel.
- A breaker that trips repeatedly usually signals an overloaded circuit or a short, not a failed breaker, and an electrician will diagnose the real problem.
- You can reset a tripped breaker yourself by switching it fully off and then back on, but if it trips again immediately, stop and call an electrician.
- The electrician will turn off the main breaker before working inside the panel, but the main breaker itself remains energized even when off.
When a breaker has actually failed versus when it has just tripped
A tripped breaker switches itself off when it detects too much current flowing through that circuit. This is the breaker doing its job — it is protecting your wiring from overheating and catching fire. You can reset a tripped breaker by flipping the switch all the way to the off position, then back to on. If the breaker trips again within seconds or minutes, do not keep resetting it; something is drawing too much power or there is a short in that circuit.
A failed breaker will not stay in the on position, will not trip cleanly (it may feel stuck or loose), or may be visibly burned or discolored. A failed breaker cannot protect the circuit anymore and must be replaced. Some breakers fail after years of normal use; others fail because they have been tripped repeatedly under load and have worn out internally.
Before you call an electrician, identify which breaker controls the circuit that is not working. Look at the main panel and find the breaker that is in the off position or in the middle (some breakers trip to a middle position rather than fully off). The breaker should be labeled with the circuit it controls — for example, "Kitchen Outlets" or "Bedroom 2". If the label is missing or illegible, an electrician can trace the circuit for you, but this takes longer and costs more.
What to tell the electrician so they can prepare
When you call, describe what happened: Did the breaker trip when you plugged something in, or did it trip on its own? Is the breaker stuck in the off position, or does it flip back off when you try to reset it? Have other breakers in the same panel tripped recently, or just this one? This information helps the electrician decide whether they are replacing a worn-out breaker or investigating a short or overload problem in your wiring.
Tell the electrician the age of your home and the age of the panel if you know it. Older panels sometimes use breakers that are no longer manufactured, and the electrician may need to source a replacement breaker before the appointment or discuss whether the panel itself needs upgrading.
Ask whether the electrician will need to turn off the main breaker to work. Most will, and this means your entire house will lose power for the duration of the repair — usually 30 minutes to an hour. If you have medical equipment that runs on electricity, tell the electrician before they arrive so they can plan accordingly.
What happens during the replacement
The electrician will arrive with the correct replacement breaker for your panel. Breakers are not universal — a breaker for a Siemens panel will not fit a General Electric panel, and the amperage rating must match the circuit it protects. The electrician will verify the correct breaker type before beginning work.
They will turn off the main breaker, which cuts power to all the branch breakers inside the panel but does not de-energize the main breaker terminals themselves or the utility lines running into the panel. This is why homeowners should not attempt this work — even with the main breaker off, the panel remains dangerous.
The electrician will remove the failed breaker by unclipping it from the bus bar (the metal rail it snaps onto) and disconnecting the wire attached to it. They will then snap the new breaker into place and reconnect the wire. Once the new breaker is secure, they will turn the main breaker back on and test the circuit to confirm it is working.
Why a breaker keeps tripping after replacement
If a new breaker trips immediately after installation, the problem is not the breaker — it is the circuit itself. This usually means there is a short in the wiring, a device plugged into that circuit is faulty, or too many high-power devices are running on the same circuit at once.
The electrician should not simply install a higher-amperage breaker to stop the tripping. A breaker is sized to match the wire gauge of the circuit; using a breaker that is too large for the wire can allow dangerous current to flow and cause a fire. If the circuit is genuinely overloaded, the solution is to redistribute the load across multiple circuits or to have the electrician run a new circuit from the panel.
Permits and inspections for breaker replacement
In many jurisdictions, replacing a circuit breaker requires a permit and a final inspection by the local building department. Some electricians include this in their fee; others charge separately. Ask whether a permit is required in your area before hiring the electrician, and confirm whether they will handle the permit or whether you need to obtain it yourself.
If you are selling your home or refinancing your mortgage, the lender or title company may require proof that any electrical work was permitted and inspected. Unpermitted electrical work can delay closing or result in the lender requiring you to have the work inspected retroactively. It is cheaper to permit the work upfront than to deal with this later.
Finding a licensed electrician in your area
Your state's licensing board maintains a list of licensed electricians. Search your state's name plus "electrician license lookup" to find the official database. You can verify that an electrician is licensed and check whether they have any complaints on file.
Ask for references from friends, neighbors, or your homeowners' association. Get at least two quotes before hiring, and confirm that each quote includes the cost of the breaker, the labor, and any permit fees. The lowest quote is not always the best — an electrician who rushes through the work or cuts corners on safety is not worth the savings.
Frequently Asked Questions
Can I reset a breaker myself, or do I need an electrician?
You can reset a tripped breaker yourself by switching it fully off and then back on. If it trips again immediately, stop and call an electrician. Repeated tripping means something is wrong with the circuit, not the breaker.
How long does it take to replace a circuit breaker?
The actual replacement usually takes 30 minutes to an hour, depending on how accessible the breaker is and whether the electrician needs to troubleshoot the circuit. Add time for the electrician to travel to your home and discuss the problem with you.
What if my panel is too old and the breaker is no longer made?
Some older panels use breakers that manufacturers have discontinued. The electrician may be able to source a used breaker from a salvage supplier, or they may recommend upgrading the entire panel. Discuss options and costs with the electrician before they begin work.
Will my homeowners' insurance cover the cost of replacing a breaker?
Most homeowners' insurance covers electrical repairs only if the damage was caused by a covered event like a lightning strike. Wear and tear or a breaker that failed on its own is usually not covered. Check your policy or call your insurer to confirm.
Is it dangerous to have a breaker that keeps tripping?
A breaker that trips is doing its job and is actually protecting you. However, if it keeps tripping, something is wrong with the circuit or a device on it. Have an electrician investigate rather than ignoring the problem or installing a larger breaker.
