How Much Does It Cost to Replace an Electrical Panel?

Last updated September 2026 by the licensed electricians at JCT Electric Inc in Denver, NC.

Quick answer: Replacing an electrical panel typically costs $1,500 to $3,000 for a replacement at the same amperage and $2,500 to $5,000 to upgrade from 100 amp to 200 amp service, including the permit. The price climbs toward $6,000 or more when the meter base and service entrance cable must be replaced, the panel has to move, or grounding needs major correction.

A panel replacement is one of the larger electrical projects a homeowner takes on, and quotes can vary by thousands of dollars for what sounds like the same job. This guide explains what a fair price looks like in North Carolina, what is included, and what makes one home cost more than another.

Electrical Panel Replacement Cost at a Glance

These are typical ranges for single family homes and are meant to help you judge a quote, not replace one. An on site assessment is the only way to get a real number.

What a Panel Replacement Price Should Include

• A load calculation to confirm the right service size
• The permit and final inspection
• Coordination with Duke Energy or EnergyUnited to disconnect and reconnect power at the meter
• The new panel, main breaker, and branch circuit breakers
• Grounding and bonding brought up to current code
• Every circuit tested and clearly labeled

If a quote does not mention the permit, the breakers, or grounding, ask. Those are the usual places a low number gets its savings.

Six Things That Change the Price

1. The service size

Swapping a 200 amp panel for a new 200 amp panel costs less than raising a 100 amp home to 200 amps, because an upgrade usually means a larger meter base, larger service entrance conductors, and utility involvement.

2. The meter base and service entrance

On older homes the meter base and the cable between it and the panel are often original and undersized. Replacing them is common on upgrades and is one of the biggest line items.

3. Grounding and bonding

Many older installations have a weak ground or none at all by today’s standards. New ground rods and bonding to water and gas piping add labor.

4. Location and clearances

Code requires clear working space in front of a panel and does not allow panels in bathrooms or clothes closets. A panel installed decades ago in a spot that no longer complies has to move, which adds wire, wall work, and time.

5. Breaker types

Arc fault and ground fault breakers cost several times more than standard breakers, and some circuits require them. A panel with thirty circuits can see a meaningful difference here.

6. Overhead or underground service

Homes fed underground sometimes need more work at the meter, and any change the utility makes to its side is scheduled on the utility’s calendar.

Signs Your Electrical Panel Needs to Be Replaced

• It is a Federal Pacific Stab Lok, Zinsco, or other panel with a known failure history. See what Lake Norman homeowners need to know about Federal Pacific and Zinsco panels.
• You still have a fuse box.
• There is rust, scorching, a burning smell, or buzzing at the panel.
• Breakers trip often, feel warm, or will not stay reset.
• There are no open spaces and circuits have been doubled up on single breakers.
• Your insurance company or a home inspector has flagged it.
• You are adding an EV charger, a hot tub, a heat pump, or a generator and the load calculation shows no room.

Replace or Upgrade: Do You Need 200 Amps?

Not every panel replacement needs to be an upgrade. A home with gas heat, a gas water heater, and a 150 amp service may be perfectly served by a new 150 amp panel. A 100 amp home that is all electric, or planning an EV charger, usually benefits from 200 amps. The load calculation answers this, which is why it should come before the quote. If an EV charger is what started the conversation, read do I need a panel upgrade for an EV charger first, because there are alternatives that cost less.

How Long Does a Panel Replacement Take?

Most residential panel replacements are completed in one day. Expect your power to be off for roughly four to eight hours while the work is done. Scheduling depends on the permit and on the utility’s availability to disconnect and reconnect service, which can add a few days to a couple of weeks before the work date.

Ways to Get More Value From a Panel Replacement

• Combine projects. Adding an EV charger circuit or a whole home surge protector during the panel swap costs less than a separate visit later.
• Size for the next ten years. If an EV, hot tub, or addition is likely, plan for it now instead of paying for a second upgrade.
• Ask for an itemized quote. It makes quotes comparable and shows you what is driving the price.
• Do not skip the permit. An unpermitted panel can complicate insurance claims and slow down a home sale.

If your home also has aging wiring, it may make sense to plan both together. We cover that combined cost in the cost to replace an electrical panel and rewire a house.

Electrical Panel Replacement FAQs

Does homeowners insurance pay to replace an electrical panel?

Usually not when the reason is age or an outdated brand. Some insurers require replacement of Federal Pacific or Zinsco panels before they will write or renew a policy, and a few offer better rates once it is done.

Do I need a permit to replace an electrical panel in North Carolina?

Yes. Panel and service replacements require a permit and inspection in every county we serve, and the utility will not reconnect a new service without an approved inspection.

How long do electrical panels last?

A quality panel commonly lasts 25 to 40 years. Moisture, overloading, and brands with known defects shorten that considerably.

Is a 100 amp panel enough for a modern home?

It can be for a smaller home with gas appliances. Homes with electric heat, an electric range and dryer, or plans for an EV charger often need 150 or 200 amps.

Can I stay home during a panel replacement?

Yes. You will have no power for several hours, so plan for refrigerators, internet, and anyone working from home.
