How Much Does It Cost to Replace an Electrical Panel?

If you're a Knoxville homeowner dealing with flickering lights, a frequently tripping breaker, or outdated fuse boxes, it's time to consider an electrical panel replacement. But how much will it cost?

Replacing an electrical panel in Knoxville typically costs between $1,500 and $4,000, depending on the size of the panel, the complexity of the job, and whether other upgrades are needed. In this blog, we’ll walk you through what affects pricing, what’s included, and how to know when it’s time to replace your panel.

Every home is different, and several factors will affect how much you’ll pay for a panel replacement or upgrade.

Panel Amperage

• 100-amp panel: Suitable for small homes or older homes with minimal energy demand.
• 200-amp panel: The standard for most modern homes. Provides capacity for large appliances and systems.
• 400-amp panel or higher: Needed for very large homes, guest houses, or homes with electric vehicles, workshops, or heavy-duty equipment.

Higher amperage panels cost more due to their larger size and the complexity of installation.

Condition of Existing System

If your wiring is outdated or unsafe, or your home still uses a fuse box, your electrician may need to do more than just swap out the panel. Additional wiring, grounding, or meter base upgrades will raise the cost.

Some older homes may have aluminum wiring or lack proper grounding, both of which require updates during a panel replacement. These updates not only affect cost but are also crucial for safety.

Location and Access

Installing a new panel in the same location as the old one is usually straightforward. But if the panel needs to be relocated—for code compliance or remodeling—expect more labor hours and a higher bill.

If your panel is located in a tight space, finished basement, or behind finished walls, access issues can add hours of labor to the job.

Knoxville Area Labor and Permit Costs

In the Knoxville area, labor rates for licensed electricians typically range from $75 to $125 per hour. Permits and inspections are required for most panel work and can add $100–$300 depending on the municipality.

Additional inspections may be required if utility coordination or major upgrades are involved.

Typical Cost Ranges (Knoxville + National Data)

While every project is unique, here are general ranges based on local and national data:

Knoxville homeowners report paying an average of $2,500 to $3,000 for a 200-amp panel replacement. This includes labor, parts, and permits.

If major upgrades are needed—like replacing the meter, extensive rewiring, or installing a sub-panel—costs can exceed $5,000.

Important: Pricing can also vary depending on the brand of panel and breakers. Higher-end brands may cost more upfront but offer longer warranties or additional safety features.

What’s Included in the Cost?

When you get a quote for panel replacement, here’s what you can expect to be included:

Materials

• New electrical panel (breaker box)
• Circuit breakers
• Wiring and conduit (as needed)
• Connectors, grounding rods, and bonding parts

Labor

• Removal and disposal of old panel
• Installation of new panel and breakers
• Reconnecting circuits and testing
• Coordinating with your local utility company, if a service shutoff is needed

Permits and Inspections

Quality electricians will handle this process for you. You should never skip this step—an inspection essential for safety and compliance with Knoxville electrical codes.

Optional Add-Ons

Some panel upgrades may include or require:

• Whole-home surge protection
• Arc fault circuit interrupters (AFCIs)
• GFCI breakers
• Sub-panels for additions or outbuildings
• Smart breaker panels that provide app-based monitoring

These extras improve safety and usability, though they will also add to the total cost.

When Does It Make Sense to Replace or Upgrade?

Not every panel needs replacing, but there are some signs you shouldn’t ignore:

Safety Risks

• Panel is more than 25 years old
• Breakers trip often or won’t reset
• Rust, corrosion, or buzzing noises
• Fuse box instead of circuit breakers

Some older panels have been flagged by inspectors due to safety concerns and may no longer meet code. If you have a panel made by Federal Pacific, Zinsco, or Sylvania, it’s a good idea to have it evaluated by a licensed electrician.

Increased Power Needs

Adding a hot tub, EV charger, or finishing a basement? You’ll likely need more amperage to power everything safely.

Knoxville homeowners adding home offices, high-end kitchen appliances, or media rooms often find their 100-amp or 150-amp panels can't keep up.

Home Remodels or Insurance Requirements

Insurance companies may require panel updates for continued coverage. Remodeling projects often trigger updates for code compliance.

Selling your home soon? An updated panel can increase buyer confidence and help pass inspections smoothly.

Tips for Knoxville Homeowners Before You Get a Quote

Know Your Panel’s Amperage

Ask for itemized estimates so you can see the breakdown of materials, labor, and permit fees. A good electrician will walk you through it.

Think About the Future

Planning to add solar, a pool, or a home office later? It may make sense to go with a higher-amperage panel now, even if you don’t need it immediately.

Future-proofing your electrical system now can save you thousands down the line.

Don’t be afraid to ask about experience, licenses, insurance, and warranties. A trustworthy electrician will gladly provide that info.
