Cost at a Glance
Upgrading your electrical panel is one of the most important safety and capacity improvements you can make to your home. Most homes built before 1990 have 100-amp panels that cannot handle modern electrical loads from EV chargers, heat pumps, and high-draw appliances. The national average for a panel upgrade is around $2,500, but costs vary by amperage, brand, and whether the utility requires a new meter base or service entrance cable.
Cost by Panel Amperage
The amperage rating of your new panel determines how much total electrical load your home can handle. A 100-amp panel is adequate for small homes without electric heating or EV charging. A 200-amp panel is the current standard for most residential construction and supports modern electrical demands including EV chargers, heat pumps, and multiple high-draw circuits. A 400-amp panel is necessary for very large homes or properties with heavy electrical loads such as workshops, pools, and multiple HVAC systems.

Panel Upgrade Components
A panel upgrade is more than just swapping the breaker box. In many cases, the electrician also needs to replace the service entrance cable (the heavy wire running from the utility meter to the panel), upgrade the meter base, and install a new grounding system. If your home has an older Federal Pacific, Zinsco, or fuse box panel, replacement is especially important because these panels have documented safety issues including fire risk. Your utility company may need to disconnect and reconnect service, which adds scheduling time.

When to Upgrade Your Panel
Several warning signs indicate your panel needs upgrading. Frequently tripping breakers, flickering lights when appliances turn on, warm or discolored panel covers, and a burning smell near the panel are all red flags. Beyond safety concerns, you will need a panel upgrade if you are adding an EV charger, heat pump, hot tub, workshop, or home addition that requires significant new electrical capacity. Most electricians recommend upgrading to at least 200 amps during any major renovation to future-proof your home.
Common Panel Upgrade Scenarios
Sub-Panel Installation
A sub-panel is a smaller secondary panel fed from the main panel, commonly used for garages, workshops, home additions, or finished basements. Sub-panels reduce the need to run individual circuits back to the main panel over long distances. They are also a cost-effective option when your main panel is full but still has sufficient amperage capacity. Typical sub-panels range from 30 to 100 amps and can accommodate 6 to 20 circuits.

Labor Costs
$75 – $120 per hour
A panel upgrade typically requires 6–10 hours of labor for a licensed electrician, plus coordination with the utility company for service disconnection and reconnection. Labor accounts for roughly 50–60% of the total project cost. The work involves de-energizing the existing panel, removing old breakers and wiring, mounting the new panel, reconnecting all circuits, and testing every breaker. A permit and final inspection by the local building department are required in virtually all jurisdictions.
Enhancement & Improvement Costs
What Drives the Cost
- Amperage increase — upgrading from 100A to 200A costs more than a same-amperage swap
- Service entrance cable — older homes often need new cable from the meter to the panel ($500–$2,000)
- Meter base replacement — may be required by the utility company ($200–$600)
- Panel brand — premium brands like Eaton and Square D cost more but offer better reliability
- Location — moving the panel to a different wall or room adds $1,000–$2,500
- Local permit and inspection fees vary from $75 to $300
Pro Tips
- Upgrade to 200 amps even if your current needs are lower — it future-proofs for EV chargers and heat pumps
- Replace Federal Pacific, Zinsco, or fuse box panels immediately due to documented safety risks
- Add a whole-house surge protector during the upgrade — it only adds $250–$500 to the project
- Get at least three quotes and verify each electrician is licensed and insured in your state
A panel upgrade typically takes 1 day, or 2 days if service entrance work is needed.
Frequently Asked Questions
How long does a panel upgrade take?
A straightforward 200-amp panel upgrade takes 6–10 hours in a single day. If new service entrance cable or a meter base replacement is needed, the project may require coordination with the utility company and could span two days.
Do I need a permit for a panel upgrade?
Yes. Panel upgrades require an electrical permit and inspection in virtually every jurisdiction. The electrician typically pulls the permit and schedules the inspection as part of the project. Never allow unpermitted panel work — it creates serious safety and resale issues.
Should I upgrade to 200 or 400 amps?
200 amps is sufficient for most homes, including those with EV chargers and heat pumps. 400-amp service is typically only necessary for very large homes over 4,000 sq ft or properties with heavy electrical demands like pools, workshops, and multiple HVAC systems.
Is my Federal Pacific or Zinsco panel dangerous?
Yes. Both Federal Pacific Stab-Lok and Zinsco panels have well-documented failure rates where breakers do not trip during overloads, creating fire hazards. Most electricians and home inspectors recommend immediate replacement regardless of whether an upgrade in amperage is needed.
