Fuse Box Replacement Cost in Los Angeles:
Complete Pricing Guide [2026]
What it costs to replace an old fuse box with a modern circuit breaker panel in Los Angeles, published pricing, the LADBS permit path, utility coordination, and how the job actually runs.

What a Fuse Box Is and Why LA Homes Still Have Them
A fuse box is a metal enclosure of screw-in or cartridge fuses that protects each circuit. When current exceeds what the fuse is rated for, the metal element melts and the circuit goes dead until a replacement fuse goes in. Circuit breaker panels do the same job with switches that simply reset.
Los Angeles still has thousands of homes wired this way. Our own panel replacement work identifies fuse boxes and 60A services across the city's oldest neighborhoods, including Echo Park and Highland Park homes, the same territory our panel upgrade teams cover daily. Houses built before the 1960s were wired for a fraction of today's load, and the fuse box was sized for that world, a household with no EV charger and no central air to feed.
Open the metal cabinet near the meter: round glass or cartridge fuses in rows, or a pull-out block holding cartridge fuses, means you have a fuse box. Replacement means removing the fuse box and installing a modern breaker panel; the job is a service panel replacement, not an accessory swap.
Fuse Box Replacement Cost in Los Angeles
Because a fuse box replacement is a service panel replacement, we quote it from the same published cost table as our panel upgrade cost guide. These are the prices we publish for Los Angeles projects:
Fuse Box Replacement: Published Cost Rows (2026)
| Scope / Item | Typical Range | Notes |
|---|---|---|
| 100 Amp to 200 Amp Upgrade | $2,500 – $4,500 | Standard 30–42 space breaker box; the range most fuse box replacements land in |
| Zinsco / Federal Pacific Replacement | $2,800 – $4,800 | Hazardous panel replacement + remediation |
| 200 Amp to 400 Amp Upgrade | $4,500 – $8,000 | Dual-panel or 320A continuous for large homes |
| New Subpanel (60A – 100A) | $800 – $2,000 | Ideal for ADUs, garages, or additions; not a main panel replacement |
| LADBS Permit & Inspection Fees | $200 – $450 | Included in AMY Electric all-inclusive quotes |
| LADWP / SCE Service Connection | $300 – $600 | Utility fee billed for line upgrade/meter spot |
| Federal 25C Tax Credit (Inflation Reduction Act) | Up to -$600 | 30% tax credit for qualifying electric panel upgrades |
Which row applies depends on what the electrician finds: a 60A fuse service feeding a modern load list almost always justifies the 100A-to-200A upgrade, and homes whose fuse boxes date from the Federal Pacific and Zinsco era often carry hazardous-brand equipment into the same job. Older homes with knob-and-tube wiring or ungrounded branch circuits may require grounding updates to pass LADBS inspection. All estimates are free and provided in writing.
What Moves Your Fuse Box Replacement Price
Meter-to-Panel Distance
Longer feeder runs, through finished walls or under a slab, add material and labor before the first breaker is set.
Service Capacity
Restoring a 60A fuse service to a modern 100A or 200A breaker panel is the common scope; dual-service and 400A projects price higher.
Overhead versus Underground Service
Replacing the service mast (overhead) or coordinating a new underground service changes the utility-side work.
Existing Wiring Condition
Knob-and-tube or ungrounded branch circuits may need grounding updates or rewiring to pass LADBS inspection.
Hazardous Panel Brand
Federal Pacific or Zinsco equipment in the same house prices from the hazardous-remediation row, not the standard row.
Utility Territory
City of Los Angeles homes coordinate with LADWP; other cities in Greater LA may fall under SCE. Fees bill through the utility either way.
How a Fuse Box Replacement Works
We add up what the home runs today and what you plan to add next, such as an EV charger, heat pump, or ADU, to size the new panel correctly.
The replacement requires an LADBS electrical permit. We file it through LADBS's online systems and cover the fee in our quote.
We coordinate the planned power shutdown and any service connection work with LADWP (City of LA homes) or SCE, depending on your address.
We remove the fuse box, set the new breaker panel, extend and terminate every circuit, and label the directory clearly.
An LADBS inspector verifies the work against the California Electrical Code. We attend, address any corrections, and hand you the closing record.
Fuses versus Breakers: What Changes
A fuse and a breaker both stop current that exceeds the circuit's safe rating. The difference is what happens next: a fuse melts and must be physically replaced, and when the household already has replacement fuses of the wrong size in a drawer, the wrong fuse ends up back in the socket, protecting nothing. A breaker is a switch: it trips, you reset it, and it protects the same circuit again.
That difference compounds on an old panel. Fuse panels age alongside their wiring, offer no room for new circuits, and provide none of the AFCI or GFCI protection that modern breaker panels install on residential circuits. Fuse boxes also predate today's load entirely: they were built when a fridge, some lights, and a radio were the whole house.
Fuse Panels, Insurance, and Escrow
The same insurance dynamics we document for hazardous legacy panels apply to fuse boxes: California insurers frequently decline to write new homeowner policies on houses with documented-hazard electrical equipment, and inspectors flag old fuse boxes on home inspection reports. On a sale, that flag typically turns into a buyer demand: a replacement credit, or the work completed before escrow closes.
A permitted replacement hands both sides what they need: a modern 30–42 space breaker panel and an LADBS inspection record in your files. If your fuse box homes equipment that is on the hazardous-brand list, see our Federal Pacific, Zinsco & Sylvania panel replacement page and our Sylvania Zinsco replacement guide.
Replacing a Fuse Box Before Installing an EV Charger
An EV charger cannot hang off a fuse panel. A Level 2 charger needs a dedicated 50A-class circuit, breaker space, and capacity the fuse box doesn't have. For EV homes the panel replacement is step one, and the charger is the step right behind it. Our published charger pricing once the panel is modern: a Tesla Wall Connector installation runs $500–$1,200, a NEMA 14-50 outlet $350–$600, and a hardwired EVSE $500–$1,200, permit included.
The efficient path is to do both as one job: when we add the charger circuit during the panel replacement, the incremental cost is typically $500 to $1,200: one permit, one utility outage, one inspection. Check the LADWP EV charger rebate guide for up to $1,000 back, and our EV charger comparison before you pick hardware.
How Long a Fuse Box Replacement Takes
The swap itself runs four to eight hours with the power off, so charge devices and plan refrigeration ahead of the outage. LADBS inspection typically follows within 48 hours of completion. If the utility must upgrade the service connection for the higher amperage, add one to three weeks that runs parallel to our work rather than in front of it. From signed estimate to passed inspection, most straightforward replacements finish within one to three weeks.
