What does an electrical panel upgrade actually cost? Real pricing by amperage and upgrade type, plus what older homes in RI and SE Massachusetts need to know.
Your electrical panel is the box that distributes power throughout your home. Most panel upgrades fall in the $1,500 to $4,000 range, but the final number depends on your current amperage, the target amperage, and whether the utility's meter base and your grounding system need work too.
Here's what different types of electrical panel work cost in 2026:
| Upgrade Type | Typical Range | Median Cost |
|---|---|---|
| 100-Amp to 200-Amp Upgrade | $1,500 – $3,000 | $2,200 |
| New 200-Amp Panel Install | $2,000 – $4,000 | $2,800 |
| 400-Amp Panel Install | $3,000 – $6,000+ | $4,500 |
| Subpanel Addition (60–100 Amp) | $500 – $1,500 | $900 |
| Meter Base Replacement | $400 – $800 | $600 |
| Permit and Inspection | $200 – $500 | $350 |
This is the most common electrical panel upgrade. Many homes built before the 1980s have 100-amp panels that can't handle modern electrical loads — central air conditioning, electric dryers, EV chargers, and home offices with multiple devices. The upgrade involves replacing the panel box, installing new breakers, and often upgrading the service entrance cable from the meter to the panel.
If your home already has 200-amp service but the panel itself is outdated, damaged, or full of recalled breakers (Federal Pacific and Zinsco panels are two common problem brands), a panel replacement swaps the box and breakers without changing the service amperage. This is also common when homeowners need more circuit slots — a full 200-amp panel with 40+ spaces gives room for current needs and future additions.
A 400-amp service is uncommon in residential homes but more homeowners are hitting the limit as they go all-electric — heat pumps, electric vehicle charging, electric cooking, and electric water heating can push demand beyond what a 200-amp panel can deliver. This upgrade requires coordination with the utility company and typically involves a new meter base, new service entrance cable, and a larger panel or dual 200-amp panels.
A subpanel is a smaller secondary panel fed from the main panel. It's a practical solution when you need additional circuits in a specific area — a garage workshop, a finished basement, or a detached building — without upgrading the main panel. Subpanels are typically 60 to 100 amps and cost much less than a full panel upgrade.
Two panel upgrades with the same target amperage can cost very different amounts. Here are the factors that move the price — for a broader look at budgeting major home projects, see our home improvement cost guide:
Going from 60 amps to 200 amps is a bigger job than 100 to 200. A 60-amp panel typically means the service entrance cable, meter base, and grounding all need replacement too. If you still have a fuse box (common in homes built before 1960), the upgrade includes converting from fuses to circuit breakers, which adds labor and materials.
Panels in easy-to-access basements are straightforward. Panels in tight crawlspaces, behind finished walls, or in locations that don't meet current code clearance requirements (36 inches of clear space in front, 30 inches wide) may need to be relocated. Moving a panel adds $500–$2,000 to the project because of the additional wiring and patching involved.
If the utility's meter base (the box on the outside of your house where the meter plugs in) can't handle the new amperage, it needs to be replaced. This adds $400–$800 and requires coordination with the utility company, who must disconnect and reconnect service. In some areas, the utility covers part of this cost.
Modern electrical code requires two grounding electrodes — typically a ground rod driven into the earth and a connection to the home's water supply piping (if metallic). Older homes may only have one or neither. Updating the grounding system adds $200–$500 but is non-negotiable for code compliance and safety.
Every panel upgrade requires a permit. Inspectors will check not just the panel work but may flag other code issues they spot — missing GFCI protection in bathrooms and kitchens, improper wiring methods, or lack of arc-fault breakers in bedrooms. Bringing these items up to code adds to the final bill, typically $200–$800 depending on what's needed.
Federal Pacific Electric (FPE) Stab-Lok panels and Zinsco panels have well-documented safety issues — breakers that fail to trip during overloads, creating serious fire risks. If your home has either brand, replacement isn't optional. These panels are uninsurable with some carriers and can complicate home sales. Challenger panels and certain Pushmatic models also have known issues. A licensed electrician can identify your panel brand and advise whether replacement is needed for safety, not just capacity. Before hiring, review tips to avoid contractor scams — electrical work is an area where unlicensed operators sometimes undercut legitimate electricians.
Panel upgrades have less room for savings than some other home projects because the work is code-driven and must be done by a licensed electrician. That said, there are a few strategies:
Panel upgrades in Rhode Island and southeastern Massachusetts come with some region-specific considerations. The housing stock is older than the national average — many homes in Providence, Warwick, Cranston, Fall River, New Bedford, and surrounding communities were built in the early-to-mid 1900s with 60-amp fuse boxes and knob-and-tube wiring.
A simple panel upgrade on one of these older homes often becomes a larger project. If the home still has knob-and-tube wiring, the electrician can't just connect old wiring to a new panel and call it done — a full or partial rewire is typically required. Rewiring a home with knob-and-tube costs $8,000–$15,000+ depending on size and accessibility, which is a fundamentally different project from a straightforward panel swap.
Local inspection requirements in RI and Massachusetts are strict. Both states require licensed electricians for panel work — no homeowner self-permits for this type of project. Massachusetts requires a separate electrical permit from the local wiring inspector, and RI requires inspection by the local building official. Expect the permit and inspection process to add 1–2 weeks to the project timeline.
| Panel Work (RI/SE Mass) | Typical Range | Notes |
|---|---|---|
| 60-Amp Fuse Box to 200-Amp Panel | $2,500 – $4,500 | Often needs new meter base and grounding |
| 100-Amp to 200-Amp Upgrade | $1,800 – $3,500 | Standard upgrade, local labor runs 10–15% above national avg |
| Knob-and-Tube Full Rewire + Panel | $8,000 – $15,000+ | Required if K&T wiring is active |
| Panel Replacement (same amperage) | $1,500 – $3,000 | For recalled panels (FPE, Zinsco) |
| Subpanel for Garage/Addition | $600 – $1,800 | Includes running feeder cable |
Labor rates for licensed electricians in this region run 10–15% above the national average. However, the Inflation Reduction Act offers up to $4,000 in rebates for electrical panel upgrades when done as part of a home electrification project (adding a heat pump, heat pump water heater, or induction stove). Rhode Island Energy and Mass Save programs may offer additional incentives for panel upgrades that enable the installation of qualifying high-efficiency equipment.
An electrical panel upgrade costs $1,500 to $4,000 or more depending on the amperage. Upgrading from 100 amps to 200 amps runs $1,500 to $3,000. A new 200-amp panel installation costs $2,000 to $4,000, and a 400-amp panel runs $3,000 to $6,000 or more.
Common signs include frequently tripping breakers, flickering lights when appliances turn on, a fuse box instead of a breaker panel, burning smell near the panel, double-tapped breakers, or a panel rated at 60 or 100 amps when your home demands more. If you're adding a major appliance like a heat pump, EV charger, or hot tub, you may also need an upgrade.
A 100-amp panel provides enough power for a small home with gas appliances and no major electrical loads. A 200-amp panel is the modern standard and handles central air, electric dryers, EV chargers, and other high-draw equipment. Most homes being built or renovated today install 200-amp panels.
A straightforward panel swap takes 4 to 8 hours. If the meter base needs replacement, the utility company needs to disconnect and reconnect service, or the grounding system needs updating, the job can take a full day or stretch into two days. Permit inspections may add a few days to the overall timeline.
Yes. Electrical panel upgrades require a permit in virtually every municipality. The permit ensures the work is inspected for code compliance and safety. Permit costs typically run $200 to $500 depending on your city or town. Working without a permit can create problems when you sell your home and may void your homeowner's insurance.
