An electrical panel distributes power from the utility service to the circuits throughout a home. Replacing it may be necessary when the existing box is damaged, overcrowded, obsolete, or unable to support modern appliances such as a heat pump, electric range, water heater, solar system, or EV charger.
In the United States, electrical panel replacement typically costs between $518 and $2,191, with an average near $1,342. Straightforward replacements may remain below $1,500, while a project involving a larger service, new meter equipment, rewiring, relocation, or utility upgrades can cost $4,500 or more.
A panel replacement is not always the same as a complete electrical service upgrade. Replacing only the breaker box generally costs less than upgrading the panel, meter, service-entrance conductors, grounding system, mast, and utility connection.

Electrical Panel Replacement Cost by Amperage
The panel’s amperage rating determines the maximum electrical current it can distribute safely. Higher-capacity panels cost more and may require larger service wires, a compatible meter socket, and utility-side modifications.
100-amp electrical panel
A standard 100-amp panel replacement typically costs $800 to $1,500 installed.
A 100-amp service may still be adequate for a smaller home with gas heating, gas water heating, and limited high-demand electrical appliances. However, it may offer insufficient capacity for a fully electric home, large central air conditioner, heat pump, electric vehicle charger, or multiple major appliances operating simultaneously.
The panel itself generally costs approximately $100 to $200 before breakers, labor, permits, and other materials.
150-amp electrical panel
A 150-amp panel generally costs $1,300 to $1,600 installed.
This capacity can provide additional room for modern appliances without the full cost of a 200-amp project. However, availability and local utility standards may make a 200-amp panel the more practical long-term option when a service upgrade is already required.
200-amp electrical panel
A 200-amp electrical panel generally costs $1,300 to $2,000 for a standard installation. Some national estimates place 100-to-200-amp upgrades between $750 and $2,000 when major service work is not required.
A complete 200-amp service upgrade can cost considerably more if the project also requires:
- New meter socket
- Larger service-entrance conductors
- New mast or weatherhead
- Grounding and bonding upgrades
- Utility coordination
- Trenching for underground service
- Panel relocation
- Exterior wall repairs
- New main disconnect
A basic panel-only quote should not be compared directly with a complete service-upgrade quote. Ask each electrician to identify which components are included.
300-amp electrical panel
A 300-amp panel commonly costs $1,800 to $3,500 installed.
This capacity may be considered for a large home with substantial electric heating, several HVAC systems, pool equipment, workshops, multiple EV chargers, or other unusually high loads.
A professional load calculation should confirm that the added capacity is necessary.
400-amp electrical panel
A 400-amp electrical service generally costs $2,000 to $4,000 for a relatively standard panel installation, but complete service work can cost much more.
Large services may use two 200-amp panels rather than one conventional 400-amp residential panel. Utility transformer, meter, underground conduit, and service-entry requirements can push the total well beyond the basic panel price.
Panel Replacement vs. Service Upgrade
Homeowners frequently use these terms interchangeably, but they describe different project scopes.
Panel replacement
A panel replacement generally involves removing the existing breaker box and installing a new panel with the same or similar capacity.
The electrician may reuse the existing:
- Utility service
- Meter
- Service conductors
- Panel location
- Branch-circuit wiring
- Grounding system, when compliant
This is usually the least expensive option.
Electrical service upgrade
A service upgrade increases the amount of power available to the home. For example, the property may move from 100 amps to 200 amps.
The project may include:
- Larger main panel
- New meter socket
- New service cable
- New mast and weatherhead
- Ground rods and bonding
- New exterior disconnect
- Utility shutoff and reconnection
- Trenching or conduit
- Permit and inspections
The panel itself represents only one part of the complete cost. Homeowners should ask whether the quote is for a breaker-box replacement or a complete service upgrade.
Labor Cost to Replace an Electrical Panel
Licensed electricians commonly charge $50 to $130 per hour, with first-hour or service-call fees of approximately $100 to $200. Panel replacements are commonly priced as flat-rate projects rather than strictly by the hour.
A straightforward panel replacement may take four to eight hours. Complex service upgrades can require one or more full working days, plus separate utility and inspection appointments.
Labor may include:
- Obtaining permits
- Coordinating the power shutoff
- Removing the old panel
- Inspecting branch-circuit wiring
- Installing the new enclosure
- Installing breakers
- Connecting service and neutral conductors
- Updating grounding and bonding
- Labeling circuits
- Testing the system
- Completing the inspection
- Coordinating utility reconnection
The home may be without electricity for several hours during the replacement.
Additional Costs That Can Increase the Price
Permit and inspection fees
Electrical panel replacement normally requires a local permit and inspection. Permit costs frequently range from $50 to $300, although some jurisdictions charge more based on the project value or service size.
Confirm that the electrician will obtain the permit and schedule the inspection.
Meter box replacement
Replacing an electrical meter box generally costs $500 to $5,000, depending on amperage, location, utility requirements, and installation complexity. Many conventional replacements fall closer to $500 to $2,100.
The utility normally owns the meter itself, while the homeowner may be responsible for the meter socket or enclosure.
Electrical mast replacement
An electrical mast carries overhead service conductors above the roofline or exterior wall. Replacement generally costs $600 to $900, plus permits, wiring, and structural bracing when needed.
The mast may need replacement when it is damaged, undersized, corroded, or incompatible with the upgraded service.
Panel relocation
Moving an electrical panel generally costs $1,500 to $3,500. Drywall repair and painting can add approximately $300 to $950.
Relocation may be required when the existing panel is:
- Inside a bathroom
- In a clothes closet
- Behind permanent cabinetry
- Too close to plumbing
- In an area without required working clearance
- Exposed to moisture
- Inaccessible for emergency shutoff
Moving the panel farther from the existing branch circuits increases wiring and labor costs.
Subpanel installation
Installing a subpanel generally costs $400 to $1,750, with many complete projects ranging from $600 to $2,200 after wiring, permits, grounding, and additional breakers are included.
A subpanel may be suitable when the main panel has adequate electrical capacity but lacks enough spaces for circuits serving a garage, addition, workshop, or pool.
A subpanel does not increase the home’s total utility service capacity.
New breakers
Modern panel replacement may require new circuit breakers rather than transferring old ones.
Standard breakers are relatively inexpensive, but arc-fault, ground-fault, dual-function, or specialty breakers cost more. The number of protected circuits required depends on local code, the existing wiring, and the scope of the permitted project.
Grounding and bonding
Older homes may need new grounding electrodes, bonding conductors, water-pipe bonding, or corrections to the neutral and grounding arrangement.
These safety updates may add several hundred dollars but are often necessary for the installation to pass inspection.
Rewiring and circuit repairs
Panel replacement does not automatically fix unsafe branch wiring. Aluminum connections, deteriorated insulation, double-tapped breakers, improper splices, overloaded circuits, and ungrounded wiring may require separate repairs.
Whole-home rewiring can add several thousand dollars to the project. CPSC advises homeowners to have suspected aluminum-wiring problems evaluated and repaired by a qualified electrician rather than attempting DIY corrections.
Signs an Electrical Panel May Need Replacement
Schedule an electrical inspection when you notice:
- Frequent breaker trips
- Flickering or dimming lights
- Buzzing or crackling sounds
- Burning odor
- Warm or hot panel cover
- Rust or corrosion
- Melted insulation
- Visible scorch marks
- Breakers that will not reset
- Fuse-based service
- No available breaker spaces
- Major appliances causing voltage drops
- Planned EV charger, heat pump, or electric range
Current cost guidance also identifies repeated breaker trips, overheating, burning smells, and increased electrical demand as common reasons to consider an upgrade.
Do not remove the panel cover or touch internal components. Parts of the panel may remain energized even when the main breaker is turned off.
Should You Replace a Fuse Box?
Replacing a fuse box with a circuit-breaker panel typically costs $1,500 to $2,000, although wiring repairs and service upgrades can raise the total.
A fuse box is not automatically unsafe when properly sized and maintained. Problems occur when homeowners install oversized fuses, use unsafe adapters, or add more electrical load than the system was designed to handle.
CPSC advises homeowners not to replace a fuse with one rated higher than the circuit wiring can safely support. Repeatedly blown fuses should be investigated by a qualified electrician.
How Much Capacity Does Your Home Need?
The correct panel size depends on a formal electrical load calculation rather than square footage alone.
High-demand equipment may include:
- Central air conditioning
- Electric resistance furnace
- Heat pump with backup heat
- Electric water heater
- Electric range
- Clothes dryer
- Hot tub
- Pool equipment
- Workshop tools
- EV charger
- Solar and battery systems
A 200-amp service is common for modern homes, but some properties can safely electrify with less capacity when loads are carefully calculated or managed.
Do not upgrade solely because a contractor says every modern home needs 200 amps. Request a documented load calculation and ask whether load-management equipment, a subpanel, or another solution could meet the project’s needs.
Electrical Panel Rebates and Tax Credits in 2026
The previous federal Energy Efficient Home Improvement Credit for qualifying electrical panel upgrades applied only to improvements placed in service through December 31, 2025. Under current IRS guidance, a panel installed in 2026 does not qualify for that former $600 federal tax credit.
However, qualifying households may still have access to state-administered Home Energy Rebates. The Department of Energy states that eligible electrical panel or circuit upgrades may receive rebates of up to $4,000, depending on household income, location, program availability, and whether the upgrade supports qualifying electrification work.
Check state and utility requirements before beginning the project. Some programs require preapproval or approved contractors.
Can You Replace an Electrical Panel Yourself?
Electrical panel replacement is not an appropriate DIY project.
The work involves:
- Utility service conductors
- High fault-current risk
- Arc-flash hazards
- Grounding and bonding
- Local code requirements
- Permits and inspections
- Utility coordination
The service conductors entering the panel may remain energized even when the main breaker is off. Incorrect installation can cause electrical shock, fire, equipment damage, failed inspections, or insurance complications.
Use a licensed and insured electrician with experience in panel and service upgrades.
How to Save Money on Electrical Panel Replacement
- Request at least three itemized estimates. Compare the same amperage and project scope.
- Ask whether it is panel-only or a full service upgrade. This prevents misleading price comparisons.
- Request a load calculation. Avoid paying for more capacity than the home requires.
- Schedule planned work before an emergency failure. Emergency electrical service generally costs more.
- Check rebates before signing. Some programs require preapproval.
- Keep the panel in its current location when compliant. Relocation adds wiring and finish repairs.
- Combine related electrical work. Adding circuits during the panel project may reduce repeated permit and service-call costs.
- Verify permit inclusion. Make sure the quote covers inspection and utility coordination.
- Ask about breaker costs. AFCI, GFCI, and dual-function breakers may significantly affect the total.
- Avoid automatically accepting the lowest bid. Confirm licensing, insurance, warranty, materials, and exact scope.

Is a 200-amp panel necessary?
Not for every home. Capacity should be based on a professional load calculation and planned appliances rather than a universal rule.
Does panel replacement include a new meter?
Usually not. The meter socket and utility meter are separate components. The estimate should state whether meter equipment is included.
Can I stay home during the replacement?
Usually, yes, but the power will be shut off for part of the project. Homeowners who rely on medical equipment, refrigerated medications, internet access, or electrically powered well pumps should plan accordingly.
Conclusion
Electrical panel replacement typically costs $518 to $2,191, with an average around $1,342. A standard 200-amp panel installation commonly falls between $1,300 and $2,000, but the price can rise considerably when the home also needs a meter box, electrical mast, service wiring, grounding upgrades, relocation, or utility work.
Before approving the project, ask for a load calculation and an itemized estimate that separates the panel, breakers, labor, permits, meter work, grounding, wiring repairs, and utility charges.
The safest and most cost-effective option is not automatically the largest panel or the lowest bid. Choose the capacity the home actually needs and have the work completed by a licensed electrician under the required permit and inspection.
