Still nursing old screw-in fuses? When you convert a fuse box to a breaker box, you improve safety, capacity, and convenience for today’s power-hungry homes. If blown fuses and limited circuits are holding you back, this guide explains how the upgrade works, what it costs in the Oklahoma City area, and how to finish the job cleanly, to code, and on time.
Why Upgrade From Fuses To Breakers
Fuse panels were common when homes had fewer circuits and small appliances. Today’s homes run HVAC systems, EV chargers, freezers, gaming PCs, and smart lighting. Breaker panels handle these loads more safely and conveniently than old fuse boxes.
Key benefits homeowners notice:
- Safety and code compliance
- Modern breakers trip reliably and are easy to reset.
- 2020 NEC requires whole-home surge protection at service equipment, which integrates neatly with a breaker panel.
- Capacity and expansion
- Room for more circuits supports remodels, additions, and outdoor living spaces.
- Higher service amperage reduces nuisance trips under heavy loads.
- Convenience and future-ready value
- Reset breakers without shopping for spare fuses.
- Supports EV charging, backup generators, and home automation.
How We Convert A Fuse Box To A Breaker Box
Every home is different, but the professional process follows a predictable, code-compliant path:
- Evaluation and load calculation
- We document existing circuits, grounding, and bonding.
- We perform a load calc to confirm the right service size and panel space.
- Permitting and scheduling
- We pull permits with your local authority having jurisdiction and coordinate inspection.
- Utility coordination and safety prep
- We schedule utility disconnects if needed and set up safe temporary power plans.
- Panel replacement and rewiring
- We remove the fuse box, mount the new service equipment, and land conductors on labeled breakers.
- We correct grounding and bonding, replace damaged feeders, and label all circuits.
- Surge protection and required devices
- We install a Type 1 or Type 2 whole-home surge protector at the service equipment to meet 2020 NEC 230.67.
- We ensure GFCI and AFCI protection where required by code.
- Inspection and power-up
- City inspection verifies compliance. We restore power and test every circuit.
- Homeowner walkthrough
- We show you how to reset breakers, explain labeling, and review warranty and maintenance tips.
Choosing The Right Amperage: 100A, 150A, or 200A
The right panel size depends on your load calculation, but these guidelines help:
- 100 amp: Works for smaller homes with modest electric loads.
- 150 amp: A strong middle ground for average homes with modern appliances.
- 200 amp: Best for homes planning EV charging, hot tubs, heavy workshop tools, or future additions.
Tip: It is often cost-effective to size up during your convert a fuse box to a breaker box project, because the labor overlap is high. Paying a little more today can prevent repeating work later.
Permits, Inspections, and Local Code Realities
In the Oklahoma City metro, licensed electricians secure permits and schedule inspections for service upgrades. Inspections reference current NEC standards adopted by the local jurisdiction. Two hard facts that often apply to your project:
- NEC 230.67 requires surge protection at the service equipment for dwelling units (2020 and later).
- GFCI protection is required in kitchens, bathrooms, garages, outdoors, and other wet areas under NEC 210.8. AFCI protection is required on many living-area circuits for fire prevention.
AccuTemp performs work to code and provides documentation for your records. Our licensed and insured electricians handle everything from paperwork to utility coordination so your convert a fuse box to a breaker box project stays on schedule.
Cost Factors in Oklahoma City
No two homes are identical, but most homeowners ask about price and timeline first. Here is what affects the total:
- Service size and panel brand
- 100A costs less than 200A. Premium panels and breakers add a little but improve reliability.
- Feeder and meter upgrades
- Older service conductors or meter bases may need replacement to meet code.
- Grounding and bonding corrections
- New ground rods, water bond, and bonding jumpers can be required.
- Circuit count and condition
- Re-terminating neat, labeled conductors goes faster than untangling brittle wires.
- Add-ons
- Whole-home surge protection, generator interlock kits, or EV charger circuits add value.
- Project logistics
- Utility scheduling, exterior repairs, or drywall restoration can change the scope.
Typical project ranges in our area often fall between $2,000 and $5,000 for a straightforward convert a fuse box to a breaker box, with complex service upgrades going higher. We provide upfront pricing with no hidden fees so you can decide with confidence.
Signs You Need To Upgrade Now
Consider moving quickly if you notice:
- Repeated blown fuses or warm panel surfaces
- Flickering lights, especially when large appliances start
- Limited circuits or frequent tripping under normal use
- Aluminum branch circuits without proper terminations
- Evidence of moisture, corrosion, or scorch marks near the panel
If any of these apply, schedule an evaluation before the next storm or heat wave. A planned convert a fuse box to a breaker box beats emergency downtime every time.
What To Expect On Installation Day
Most conversions complete in a single day once permits are in place. A typical timeline:
- Morning shutoff and prep
- Utility disconnect, panel removal, surface repairs if needed.
- Midday installation
- Mount new panel, land feeders, install breakers, correct grounding and bonding.
- Afternoon testing and inspection
- Confirm polarity, torque, labeling, and device operation.
- Power restoration and walkthrough
- Restore power same day in most cases after inspection release or utility reconnect.
We protect floors, clean the work area, and keep you updated at each step. Our goal is a smooth, predictable convert a fuse box to a breaker box experience.
Add-On Upgrades That Protect Your Investment

- Dedicated EV charger circuit and load management
- Generator interlock or transfer switch for safe backup power
