Fuse Box Replacement Cost: Converting to a Breaker Panel
Replacing a fuse box with a modern breaker panel typically costs $2,000 – $4,500 installed for a like-for-like service size, and $2,500 – $5,500 if you upgrade from a 60 or 100 amp fuse service to 200 amps at the same time. A fuse box is not dangerous by itself, but converting it removes the overfusing risk and clears most insurance and resale hurdles. Here is the breakdown.

Is a fuse box dangerous?
A fuse box that is intact, properly fused, and not overloaded is not inherently dangerous. Fuses are a sound overcurrent device. The real problems are practical and behavioral. Fuses are easy to "overfuse": a homeowner with a circuit that keeps blowing a 15-amp fuse screws in a 20 or 30-amp fuse to stop the nuisance, which lets the wire overheat behind the wall. A breaker cannot be casually upsized that way.
The other issues are age-related. Most fuse boxes are 60 or 100 amps, which strains a modern household, and the wiring they serve is often ungrounded or includes knob-and-tube. So while the fuse box is not the hazard, the system around it usually is, and a conversion is the natural moment to address it.
What the conversion actually involves
Converting a fuse box to a breaker panel is more labor than a breaker-to-breaker swap because every branch circuit has to be re-terminated. The electrician removes the fuse panel, mounts a new load center, and lands each existing circuit on its own breaker, sizing the breaker to the wire. Along the way, the inspector expects current-code grounding, bonding, and AFCI/GFCI protection where required.
That re-termination is where surprises surface. Old fuse services frequently have multiple wires under one fuse, undersized neutrals, or ungrounded circuits. Bringing them onto individual breakers can reveal circuits that need splitting or wiring that needs repair. A good electrician opens the fuse box during the quote so those items are priced up front instead of arriving as change orders.
Why insurers and buyers push for it
Fuse boxes are a recurring sticking point in home insurance and home sales. Many insurers will not write a new policy, or will charge more, for a home still on fuses, citing the overfusing fire risk and the typical age of the wiring behind it. Some require the conversion as a condition of coverage.
On the sale side, a fuse box shows up in nearly every electrical inspection report and becomes a negotiating point. Buyers ask for a credit or a conversion before closing. Because the conversion is a known $2,000 – $4,500 line item, the same range as a standard panel replacement, doing it proactively often nets better than taking the hit at the closing table, where the buyer's estimate tends to run high.
Convert at the same amperage or upgrade?
Since the panel is coming off the wall anyway, the natural question is whether to also raise the service to 200 amps. The incremental cost of upgrading during the conversion is far less than doing two separate projects later, because the labor, the permit, and the service coordination overlap. Going from a fuse-box conversion to a 200-amp service typically adds roughly $500 – $1,500 over a like-for-like conversion.
Whether it is worth it depends on your plans. If the home is gas-heated, modest in size, and you are not adding EV charging or electric appliances, a 100-amp breaker panel is plenty. If electrification is on the horizon, doing the 200-amp upgrade now avoids paying the service-work premium twice. A load calculation during the quote makes the call concrete.
