What Is an Electrical Panel Upgrade?
An electrical panel upgrade is the process of replacing your home’s main breaker panel — often an older 100-amp or 150-amp panel, or an outdated fuse box — with a modern, higher-capacity 200-amp (or larger) electrical panel. Also called a service upgrade or load center replacement, the panel houses the main breaker and circuit breakers that distribute power to every circuit and protect your wiring from overloads and short circuits.
A full upgrade can also include the service entrance — the meter base, service mast, weatherhead, and service-entrance conductors — plus proper grounding and bonding and new bus bars sized for today’s loads. We start every job with a load calculation to confirm the right amperage (100, 150, 200, or 400 amp), then install modern breakers, including GFCI and AFCI protection where code requires.
As homes add EV chargers, heat pumps, mini-split HVAC, tankless water heaters, and hot tubs, older panels — and unsafe designs like split-buss panels or recalled Federal Pacific (FPE) and Zinsco boxes — simply can’t keep up safely. We install trusted brands like Square D, Eaton, and Siemens, all to current Florida electrical code (NEC / NFPA 70), fully permitted and inspected.
What a Panel Upgrade Includes
- Load calculation & correct amperage sizing
- New 200-amp main breaker panel
- Modern breakers (GFCI/AFCI where required)
- Code-compliant grounding & bonding
- Meter base & service mast (if needed)
- Permit, utility coordination & inspection
- Neatly labeled circuits
- Clean, tidy installation
KNOW THE DIFFERENCE
Panel Upgrade vs. Replacement vs. Repair
People often use these terms interchangeably, but they mean different things — and knowing which one you actually need can save you money. Here’s how our electricians break it down:
Electrical Panel Upgrade — Increasing your home’s electrical capacity, usually by moving from a 100-amp (or 150-amp) service to a modern 200-amp panel. This is the right choice when you’re adding an EV charger, HVAC system, addition, or simply outgrowing your current power. It often includes a new main breaker, bus bars, and sometimes a service mast and meter.
Electrical Panel Replacement — Swapping out a failing, damaged, or unsafe panel with a new one of similar capacity. This is common with outdated or recalled panels (like Federal Pacific Electric or Zinsco), fire-damaged panels, or units with corroded, overheated, or obsolete breakers. The goal is safety and reliability rather than more capacity.
Electrical Panel Repair — Fixing a specific problem without replacing the whole panel — such as a faulty breaker, a loose connection, a burnt bus bar lug, or a double-tapped circuit. When a panel is otherwise sound and up to code, a targeted repair is often all that’s needed. If the panel is obsolete or unsafe, though, we’ll always recommend the safer long-term fix.
Not sure which one applies to your home? We’ll assess it honestly and only recommend what you actually need.
IS IT WORTH IT?
Do You Actually Need a Panel Upgrade?
An older panel isn’t automatically a dangerous one — age alone doesn’t mean you need to replace it. What matters is capacity, condition, and safety. Here’s an honest look at when an upgrade is truly worth it, and when a simple inspection may be all you need.
You likely need an upgrade if…
- Your panel is full — no room for new breakers
- You have a fuse box, FPE, Zinsco, or split-buss panel
- You're adding an EV charger, heat pump, or home addition
- Breakers trip often, or the panel is warm or buzzing
- You're on 100-amp service and maxing it out
- There's rust, scorching, or a burning smell
You may be fine for now if…
- Your panel is a modern 150–200 amp breaker panel
- No safety signs — no heat, rust, or burning smell
- Breakers rarely trip and everything runs reliably
- You're not adding major new electrical loads
- A licensed inspection confirms it's safe with spare capacity
💡 Insurance tip: Many Florida insurers won’t write — or may drop — a policy on a home with a Federal Pacific, Zinsco, or fuse-box panel. Upgrading to a modern, code-compliant panel protects both your family and your home insurance coverage.
SIGNS YOU NEED AN UPGRADE
6 Signs It's Time to Upgrade Your Panel
Breakers Keep Tripping
If resetting breakers is a regular chore, your panel likely can't handle your home's load.
Flickering or Dimming Lights
Lights that flicker when appliances kick on often point to an overloaded panel.
You Still Have a Fuse Box
Fuse boxes are outdated and a common insurance red flag — a breaker panel is far safer.
Not Enough Outlets
Relying on power strips and extension cords everywhere means you've outgrown your panel.
Adding an EV Charger or Appliance
New EV chargers, hot tubs, or HVAC often need more capacity than an older panel provides.
Warm Panel or Burning Smell
A hot panel, buzzing, or burning smell is a serious hazard — get it inspected right away.
WHY IT'S WORTH IT
Benefits of Upgrading Your Electrical Panel
More Electrical Capacity
A 200-amp panel gives your home room for modern demands — HVAC, EV chargers, hot tubs, and future additions.
Improved Safety
New breakers and proper grounding drastically reduce the risk of overloads, arcing, and electrical fires.
EV & Appliance Ready
Adding a Level 2 EV charger or a big appliance? An upgraded panel provides the dedicated capacity they need.
Higher Home Value
An updated 200-amp electrical service is a strong selling point and reassures home inspectors and buyers.
Insurance & Code Compliance
Many insurers flag old fuse boxes and recalled panels. Upgrading brings you up to current Florida electrical code.
Fewer Breaker Trips
No more running to the panel when the microwave and A/C run together — enjoy stable, reliable power.

PANEL UPGRADE COST
How Much Does an Electrical Panel Upgrade Cost?
Most residential electrical panel upgrades in the Tampa Bay area cost roughly $1,500 to $4,000. A straightforward 100-amp to 200-amp swap sits at the lower end, while jobs that also need a new meter base, service mast, grounding upgrades, or a panel relocation run higher — occasionally $6,000+ for complex or commercial work.
Because the final price depends on your home’s specifics, we give you a firm, itemized quote after a quick assessment — no hidden fees, no pressure. Your free estimate tells you exactly what you’ll pay before any work begins.

Frequently Asked Questions
Straight answers about panel upgrades, cost, permits, and safety across Tampa Bay & Southwest Florida.
How much does an electrical panel upgrade cost?
It depends on your home’s size, the amperage you need, and the condition of your existing service — a straight 200-amp upgrade costs less than one that also needs a new meter or service mast. After a quick assessment we give you a clear, firm quote up front, so there are no surprises.
How long does a panel upgrade take?
Most residential panel upgrades are completed in a single day. There’s a short power interruption while we swap the panel, and we coordinate the utility disconnect/reconnect and inspection so the whole process stays smooth for you.
Do I need a permit to replace my panel?
Yes — panel upgrades require a permit and inspection in Florida. We pull the permit, handle the utility coordination, and schedule the inspection for you as part of the job.
Should I upgrade to a 200-amp panel?
For most modern homes, yes. 200-amp service comfortably handles today’s loads — central HVAC, EV chargers, hot tubs, and more. If you’re still on 100-amp service or a fuse box, upgrading adds capacity and safety and can help with insurance.
Is my old fuse box or panel dangerous?
Old fuse boxes and certain outdated panels (like Federal Pacific or Zinsco) are known fire and safety risks. If yours trips often, feels warm, buzzes, or smells like burning, have it inspected right away — we’ll tell you honestly whether it needs replacing.
Do you handle the inspection and utility coordination?
Yes. We manage the entire process — permit, panel installation, utility disconnect/reconnect, and the final inspection — so you don’t have to chase anything down.
How long will my power be off during the upgrade?
During the actual panel swap, your power is off for roughly 4 to 8 hours while the utility disconnects the service, we replace the panel, and the utility reconnects. We coordinate the disconnect and reconnect with your utility ahead of time, so the outage is as short and predictable as possible — and most panel upgrades are still completed in a single day.
What size electrical panel does my home need?
Most modern Tampa Bay homes are best served by a 200-amp panel. Smaller homes may be fine at 150 amp, while larger homes or those with heavy loads — EV chargers, heat pumps, pools, or workshops — may need 300 to 400 amp. We perform a load calculation to confirm the right amperage for your home, so you’re never over- or under-sized.
Can my panel be repaired instead of replaced?
Sometimes. A single faulty breaker, loose lug, or bad connection can often be repaired. But if your panel is undersized, corroded, a recalled brand (Federal Pacific or Zinsco), or an old fuse box, a full replacement is the safer long-term fix. We always assess honestly and recommend a repair when that’s genuinely all you need.
Will a renovation or new EV charger require a panel upgrade?
Often, yes. Adding a Level 2 EV charger, heat pump, pool, addition, or finished living space increases your electrical load — and if your panel is full or near capacity, you’ll need more amperage or open breaker space. A quick load calculation tells us whether your current panel can handle the new load or should be upgraded first.
I have a Federal Pacific or Zinsco panel — how worried should I be?
Fairly worried. Federal Pacific (FPE), Zinsco, Pushmatic, and Sylvania panels have a documented history of breakers that fail to trip during a fault — a real fire risk — and many insurers flag or refuse to cover them. If you have one, replacing it with a modern, code-compliant panel is one of the most important safety upgrades you can make.
Which panel brands do you install?
We install trusted, widely-supported brands like Square D, Eaton, and Siemens, sized correctly for your home and fully compliant with current Florida electrical code (NEC / NFPA 70). We also safely remove and replace outdated or recalled panels, including fuse boxes, FPE, Zinsco, Pushmatic, and split-buss designs.
