Fuse Box to Breaker Panel: Cost and Process

Updated 2026-10-30

Replacing a fuse box with a circuit breaker panel typically costs $1,500 to $4,500, depending on the amperage you choose, according to Fixr (updated January 2025). Bob Vila puts the switch at $1,500 to $2,000 or more, depending on how much new wiring is needed. The work needs a permit, an inspection and a licensed electrician (Fixr), and the total climbs if the house’s wiring has to be upgraded or the panel has to move.

Fuse box to breaker panel: typical cost

Both guides start at $1,500, but they explain the spread differently: Fixr’s range runs to $4,500 and ties the price to the amperage of the new panel, while Bob Vila’s tops out at $2,000 “or more” and ties it to how much new wiring is needed. The two guides use different data, so treat both as a sanity check for a quote, not as a price list. Fixr notes that labor can be 40% to 60% of the total cost of the job.

What adds to the price

• Amperage. Fixr ties the price to the amperage of the new panel. If you’re adding an EV charger, a heat pump or an addition, see Do I Need 200 Amp Service? and 200 Amp Panel Upgrade Cost.
• The wiring behind the panel. Fixr says the job can take several days, depending on the wiring in your home and whether it needs to be upgraded. If the house still has knob-and-tube wiring, see Knob-and-Tube Replacement Cost.
• Moving the panel. This Old House says the price of a move depends on distance and rewiring needs; Fixr says a move adds a few days of labor.
• The utility. Fixr notes that some municipalities require an inspection by the local power company before any work begins, and the utility may ask for changes such as a new panel location.

Is a fuse box unsafe or just outdated?

Fuses and breakers do the same job: they interrupt power to a circuit during an overload. A fuse has to be replaced after it blows, while a breaker can be reset (Fixr). Fixr says fuse boxes were installed up to the 1960s and that most are too small for today’s electrical needs.

The sources differ in tone:

• This Old House says fuse boxes, while functional, offer less protection and convenience than modern breakers, and recommends replacing an old fuse box with a breaker system as soon as possible.
• In a This Old House buying guide, master electrician Heath Eastman says an outdated system isn’t automatically unsafe — but he treats screw-in fuses and knob-and-tube wiring as red flags to replace and budget for.
• Bob Vila warns that fuse boxes weren’t designed for the amount of electricity a modern home uses, and that installing bigger fuses can increase the possibility of a fire.

In a 1980 release about checking home wiring before adding thermal insulation, CPSC staff listed frequent blown fuses or tripped breakers, flickering lights, and outlet covers or switch plates that become hot as signs of wiring problems. The release advised having a qualified person make sure fuses and breakers are the proper size, and said that once insulation is installed, the fire potential from damaged wiring or over-fused circuits is greatly increased. If fuses blow often, have a licensed electrician find out why — and have the wiring checked before any insulation work.

If the panel feels warm or buzzes, have a licensed electrician look at it soon. If you smell burning, see smoke, or the panel is hot to the touch, leave the area and call 911.

Insurance and selling a house

None of the cost guides above says how insurers treat fuse boxes. Ask your insurer whether a fuse box affects your coverage or premium, and what paperwork they want after the upgrade, such as the passed final inspection. This Old House notes that improper work can lead to code violations that may affect your home insurance coverage — one more reason to use a licensed electrician and a permit.

If you’re buying a house and the inspection report mentions fuses, get a written quote before closing so you know the cost.

What happens during the replacement

This is what the job looks like from the homeowner’s side. It is not a how-to: this is work for a licensed electrician with a permit.

1. Evaluation and quote. An electrician inspects the existing system first. Fixr says this inspection isn’t required by law but usually happens anyway so the job can be priced correctly; it costs $125–$250.
2. Permit. Fixr says panel work needs a permit, costing $50–$300 or more. Bob Vila says electricians often pull it and include the cost in the quote. More in Electrical Panel Upgrade Permits.
3. Utility check, where required. Some municipalities require an inspection by the power company before work begins (Fixr).
4. Installation day. Fixr says the installation takes four to eight hours with two electricians and may take several days if wiring needs upgrading. Bob Vila suggests asking how long your house will be without electricity.
5. Final inspection. Bob Vila says the city inspection after the work is usually included in the permit cost. Keep the passed inspection for your records.

Questions to ask your electrician

• What amperage do you recommend for this house, and why?
• Does the quote include the permit and the final inspection?
• Does any wiring need to be upgraded, and is it priced separately?
• Will the new panel go in the same place? If not, what does the move add?
• Does the utility need to inspect or reconnect, and are those fees in the price?
• How long will the house be without power?

FAQ

Can I replace a fuse box myself? This site doesn’t give instructions for electrical work. Fixr says this work requires a permit, an inspection and a licensed electrician; This Old House calls panel upgrades not DIY-friendly.

How long does the switch take? Four to eight hours with two electricians, according to Fixr, or several days if the wiring needs work.

Will homeowners insurance pay for the upgrade? Ask your insurer — and ask whether your current fuse box affects your policy.
