This circuit breakers cost guide for homeowners covers what you will pay in 2026. A standard single-pole circuit breaker costs $5 to $15 for the part and $150 to $300 installed by an electrician — including the service call, labor, and testing. The breaker itself is cheap. The electrician’s time is what you are paying for. Most breaker replacements are straightforward — remove the old breaker, snap in the new one, reconnect the wire, verify proper operation — and take an electrician 30 to 60 minutes.
The cost climbs when the breaker is not a standard replacement. AFCI and GFCI breakers cost more than standard breakers. A new circuit requires running new wire. A panel upgrade requires replacing the entire panel enclosure. And a recalled or obsolete panel may need full replacement regardless of the breaker condition. Here is what each scenario costs.
Circuit Breaker Costs by Type
| Breaker Type | Part Cost | Installed Cost | What It Does |
| Standard single-pole (15A or 20A) | $5 – $15 | $150 – $300 | Overload and short-circuit protection |
| Standard double-pole (30A-60A) | $15 – $50 | $200 – $400 | 240V appliances: dryer, range, water heater, AC |
| GFCI breaker (single-pole) | $40 – $60 | $250 – $450 | Ground-fault protection — required near water |
| AFCI breaker (single-pole) | $40 – $60 | $250 – $450 | Arc-fault protection — required in living areas |
| Dual-function AFCI/GFCI breaker | $50 – $80 | $300 – $500 | Both arc-fault and ground-fault protection |
| Smart breaker (WiFi-enabled) | $50 – $100 | $300 – $500 | Remote monitoring, energy tracking, app control |
AFCI and GFCI breakers cost $40 to $80 for the part, four to five times the cost of a standard breaker, because they contain microprocessors that continuously monitor the electrical waveform for arc-fault or ground-fault signatures. A standard breaker is a simple thermal-magnetic switch. An AFCI breaker is a computer attached to a switch. The price difference reflects the technology inside.
When to Replace a Circuit Breaker
A circuit breaker that trips occasionally under normal load, a hair dryer and a space heater on the same circuit, for example, is doing its job. The circuit is overloaded, and the breaker is protecting the wiring from overheating. The solution is to redistribute the load, not to replace the breaker.
A circuit breaker that trips repeatedly with no load or very light load, a few LED lights, a phone charger, may be failing. Breakers have a finite number of trip cycles before the internal mechanism wears out. A breaker that has tripped hundreds of times over decades of service may trip at a lower current than its rating. An electrician can test the breaker with a load tester to determine whether it is tripping at its rated current. If it is not, replacement is needed.
A circuit breaker that feels hot to the touch, smells like burning plastic, or shows visible scorch marks on the panel cover around it is an emergency. Turn off the main breaker if you can do so safely and call an electrician immediately. A hot breaker indicates a loose connection at the bus bar or the wire terminal, a high-resistance point that is generating heat and may be arcing inside the panel. This is a fire hazard, not a maintenance item.
The U.S. Consumer Product Safety Commission (CPSC) has investigated breaker failure rates in certain older panel brands, notably Federal Pacific Electric (FPE) Stab-Lok and Zinsco panels, where breakers have been found to fail to trip under overload conditions at a significantly higher rate than modern breakers. If your home has an FPE or Zinsco panel, replacing individual breakers is not a reliable solution, the panel itself should be replaced. The breaker failure rate in these panels is systemic, not isolated.
Adding a New Circuit, Breaker Plus Wiring
Adding a new circuit to an electrical panel costs $350 to $700 for a standard 120-volt, 20-amp circuit. The cost includes the breaker, the Romex cable from the panel to the new outlet or fixture, the outlet box and receptacle, and the labor to run and secure the cable. A 240-volt circuit, for an EV charger, electric dryer, or induction range, costs $500 to $1,200 and requires a double-pole breaker and heavier-gauge cable.
The largest variable in adding a new circuit is the distance from the panel to the destination. A new outlet on the wall directly above the panel in the basement costs $350. A new outlet on the second floor on the opposite side of the house costs $700 because the cable must be fished through two floors of finished walls. The materials cost roughly the same. The labor difference is entirely about access.
When the Panel Needs Upgrading, Not Just the Breaker
If the electrical panel is full, no empty slots for new breakers, an electrician can install tandem breakers, which fit two circuits into a single slot, at a cost of $150 to $300 per tandem breaker installed. Tandem breakers are a stopgap. They work when the panel has physical slots available for tandem configurations and the total load on the panel is still within its rated capacity. A panel that is physically full and electrically near its capacity cannot be solved with tandem breakers. It needs a panel upgrade or a subpanel.
A subpanel, a smaller electrical panel fed from the main panel, costs $800 to $2,000 installed and adds 12 to 24 new circuit slots. It is the right solution when the main panel is physically full but electrically has adequate capacity to support additional circuits. A subpanel installs near the main panel and is fed by a large breaker, typically 60 to 100 amps, from the main panel. It does not increase the total electrical capacity of the house. It increases the number of available circuit slots.
A full panel upgrade, replacing a 100-amp panel with a 200-amp panel, costs $1,500 to $3,500 and addresses both physical slot limitations and electrical capacity limitations. It is the correct solution when the house needs more total electrical capacity, for an EV charger, a heat pump, an ADU, or a major renovation that adds significant electrical load. The panel upgrade is a larger project than a breaker replacement, requiring coordination with the utility to disconnect and reconnect the service drop, and a full day or two with the power off.
Frequently Asked Questions
How much does it cost to replace a circuit breaker?
Replacing a standard circuit breaker costs $150 to $300 installed. The breaker itself costs $5 to $15. The electrician’s labor and service call account for the rest. AFCI or GFCI breaker replacement costs $250 to $500 because the breakers themselves cost $40 to $80.
How do I know if a circuit breaker is bad?
Signs of a failing breaker include: it trips repeatedly with little or no load, it feels hot to the touch, it smells like burning plastic, it will not reset, the handle moves to the ON position but the circuit remains dead, or it trips at a lower current than its rating. A hot or burning-smelling breaker is an emergency. Turn off the main breaker and call an electrician.
Can I replace a circuit breaker myself?
A homeowner can replace a standard breaker in a modern panel by turning off the main breaker, removing the panel cover, unscrewing the wire from the old breaker, snapping out the old breaker, snapping in the new one, reconnecting the wire, and replacing the cover. The main breaker does not de-energize the service entrance cables, which remain live. If you are not confident working inside an electrical panel with live components present, hire an electrician. The $150 labor charge is insurance against a shock or a loose connection that causes a fire.
What is the difference between an AFCI and a GFCI breaker?
A GFCI breaker protects against electric shock by detecting current leaking to ground, through a person or water. An AFCI breaker protects against fire by detecting arc faults, sparks between loose or damaged wires. GFCI protection is required near water sources. AFCI protection is required in living areas and bedrooms. A dual-function AFCI/GFCI breaker provides both types of protection in a single unit.
Can I add more breakers to a full electrical panel?
If the panel has physical slots but they are all occupied, tandem breakers, two circuits in one slot, may be an option at $150 to $300 per tandem breaker. If the panel is both physically full and electrically near capacity, you need a subpanel, $800 to $2,000, or a full panel upgrade, $1,500 to $3,500. An electrician can assess your panel’s capacity and recommend the appropriate solution.
Why does my breaker keep tripping?
A breaker that trips under heavy load, a space heater and a hair dryer on the same circuit, is doing its job. The circuit is overloaded. Redistribute the load or add a dedicated circuit. A breaker that trips under light load or no load may be failing and should be tested by an electrician. A breaker that trips instantly when reset indicates a short circuit, a hot wire touching a neutral or ground wire somewhere in the circuit. This is a serious condition that requires an electrician to locate and repair the short.
What a Working Breaker Costs
A standard breaker replacement costs $150 to $300 and solves the problem for another 20 to 30 years. An AFCI or GFCI upgrade costs $250 to $500 and adds a layer of protection that a standard breaker does not provide, arc-fault detection for fire prevention, ground-fault protection for shock prevention. A new circuit costs $350 to $700 and adds capacity where none existed. A panel upgrade costs $1,500 to $3,500 and increases the total electrical capacity of the entire house.
The breaker is the last line of defense between a wiring fault and a fire. It is the cheapest component in the electrical system and the most important. A $5 breaker that fails to trip during an overload is not a $5 problem. It is a house fire. Replace breakers that are hot, breakers that will not reset, and breakers in panels known to have systemic failure rates. The rest can wait. The ones that cannot are the ones sending you a signal, heat, smell, repeated unexplained tripping, that something is wrong. Listen to the signal. The breaker is trying to tell you something. It does not speak in words. It speaks in trips, in heat, in the faint smell of ozone around the panel cover. Pay attention. Ever had a breaker trip and muttered under your breath while you walked to the basement to reset it? That walk, irritating as it is, is the breaker doing the job it was designed to do. The alternative — a breaker that should trip and does not — makes no sound at all. Until the fire starts.
