A standard 200-amp panel upgrade in Tampa Bay takes four to eight hours on installation day. Power is off for the bulk of that time — typically three to five hours. Most jobs finish the same day. Most homeowners are back on power before dinner.
The full project timeline — from signed quote to passed inspection — runs one to three weeks. Permit approval, utility coordination, and the county inspection visit add days to the administrative side. The physical work is one afternoon.
Signs You Actually Need a Panel Upgrade
The $89 diagnostic confirms it. But these are the signs that almost always lead to a replacement quote.
Breakers tripping on normal loads. One breaker tripping once is a circuit issue. Multiple breakers tripping regularly on normal household loads means the panel can't handle the demand.
Warm or discolored breakers. Touch the front face of each breaker. Room temperature is normal. Warm to the touch means current is leaking. Discoloration around a breaker means it has already overheated.
A burning smell near the panel. Stop reading. Call (727) 222-9892 now. A burning smell from the panel is an emergency electrical call — not something to monitor.
A Federal Pacific or Zinsco panel. These panels have documented breaker failure rates. Most Florida insurance carriers won't write or renew a policy on a home that has one. Read the full breakdown here.
A non-renewal notice from your insurer. The four-point inspection flagged the panel. Replace it before shopping for new coverage. Waiting until the policy lapses is the expensive version of this conversation.
You're adding a high-draw load. EV charger, hot tub, large air compressor — any 40–50 amp circuit on a panel already near its limit. The $89 diagnostic includes a load calculation that tells you whether the panel has available ampacity before any quote is written.
The Four Stages of Installation
Stage 1 — Shutdown and removal (45–60 minutes)
The electrician coordinates with your utility company to disconnect power at the meter. Once confirmed, the old panel is de-energized, breakers removed, enclosure off the wall. This is the point of no return — your home has no power until the new panel is energized.
If the meter base is corroded or isn't rated for the new service amperage, it gets replaced here. That adds one to two hours and may require a separate utility callout.
Stage 2 — New panel installation and circuit landing (2–3 hours)
The longest stage. New enclosure on the wall. Service wires in. Every circuit landed on a new breaker and labeled. A typical Tampa Bay home has 20–30 circuits. Each one gets connected, torqued, and labeled. Larger homes with 40–50 circuits take the full three hours.
This is where complications from older wiring show up. Federal Pacific or Zinsco panels sometimes have wiring that doesn't terminate cleanly — some circuits need pigtailing or splicing before they can land on the new panel. Knob-and-tube or aluminum wiring requires additional handling at every connection.
Stage 3 — Final check before power (15–30 minutes)
Every connection is verified. No uncapped wires. Grounding system confirmed. The NEC requires a full inspection of all conductors before energizing a new panel. This isn't optional — and it's not rushed.
Stage 4 — Restoration and testing (30–45 minutes)
Power comes back on. Every circuit is tested. Breaker sizing is confirmed for each circuit. You walk through the new panel labeling with the electrician. You get written documentation of the installation before the crew leaves.
What Adds Time to a Panel Upgrade
Meter base replacement. Corroded, damaged, or undersized for the new service amperage. Budget one to two additional hours and possible utility coordination.
Hazardous wiring. Aluminum wiring, knob-and-tube, or deteriorated insulation requires special terminations or replacement sections at every connection point. Discovering this mid-job adds time that wasn't in the original quote — which is why the $89 diagnostic includes a full wiring assessment.
Panel location and access. A panel tucked in a packed closet, mounted in a crawlspace, or in an awkward corner takes longer than an open garage wall. Clear the area before the crew arrives — three feet of clear space in front of the panel minimum.
Fuse box to breaker panel. Upgrading from a fuse box rather than replacing an existing breaker panel is a more involved job. The wiring terminations are different, and fuse-box homes tend to be older — higher likelihood of outdated wiring that needs correction before the new panel can be connected properly.
Rust and moisture damage. Florida humidity works on anything metal. Rusted bus bars or moisture inside the enclosure adds diagnosis and component replacement time you wouldn't know about until the panel is open.
Fuse Box vs. Breaker Panel
A fuse box uses single-use fuses that blow during an overload. A breaker panel uses resettable breakers. Most Tampa Bay homes built after the 1960s already have breaker panels.
If you have a fuse box, the replacement takes longer and costs more than a standard panel swap. The wiring terminations are different, and fuse-box homes tend to have older wiring throughout the house. The $89 diagnostic tells you what you're starting with before any quote is written.
If you're not sure which you have: look at the panel cover. A fuse box has round glass or ceramic fuses in sockets. A breaker panel has rows of switches with On/Off markings.
The Permit Timeline
The physical installation finishes in one day. The permit adds time on either side.
Before the job: The permit application is submitted to the county. In Pasco, Hillsborough, and Pinellas, approval typically takes one to five business days depending on the jurisdiction and current backlog. We handle the application — you don't contact the county.
After the job: The county schedules an inspection, usually within two to five business days of the installation. The panel needs to be accessible with the cover off so the inspector can see the work. You don't need to be present as long as someone can provide access.
The passed inspection documents that the work was done to code. You'll need it for your homeowner's insurance renewal letter and when you sell the home. It's also what separates a licensed job from an unlicensed one.
Will you be without power overnight? No. Power is restored before the crew leaves on installation day. The permit inspection happens days later and does not require another power interruption.
How to Prepare for Installation Day
Charge devices the night before. Power is off for three to five hours. Have your phone fully charged. If you work from home, plan to be somewhere with power that morning.
Plan for medical equipment. Anyone using power-dependent equipment — CPAP machines, home oxygen, powered wheelchairs — should arrange an alternative source or location for the duration. We can coordinate an early start to minimize the outage window. Call us when scheduling.
Plan for heat. Florida at noon without AC is not comfortable. Florida at noon without AC with active electrical work is worse. We schedule panel upgrades for early morning starts — typically 7:00 or 8:00 AM — to restore power before peak afternoon heat.
Plan for pets and children. The job requires open access to the panel area and electricians moving in and out of the home throughout the job. Keep pets and young children away from the work area. A dog underfoot in an active electrical workspace is a problem for everyone.
Clear the panel area. At least three feet of clear working space in front of the panel and a clear path to the meter. Move stored items and shelving before the crew arrives, not while they're standing there.
Is it a messy job? No. A panel replacement doesn't involve cutting drywall or running new circuits through walls (unless that work is separately quoted and agreed). The job is contained to the panel enclosure and the meter. The crew cleans up before leaving.
Panel Upgrade vs. Service Upgrade
These terms get used interchangeably. They mean different things.
A panel upgrade replaces the breaker box — the enclosure, the main breaker, and all the individual breakers inside. The utility wires feeding your home stay the same.
A service upgrade increases the amperage at the point where the utility company's line connects to your house. This requires utility company involvement and a different, more involved project.
Most Tampa Bay homes built after 1980 already have 200-amp service at the street. What they need is a panel replacement — not a full service upgrade. The $89 diagnostic confirms which applies before any work is quoted. Misdiagnosing this wastes money.
Combining the Panel Upgrade with Other Work
A panel upgrade is the right time to add other electrical work. The panel is already open and the service is already disconnected. Scheduling the same work separately later costs more in labor.
[EV charger circuit.](/electrical/ev-charger-installation/) Adding a 40–50 amp dedicated circuit for an EV charger during the panel replacement costs less than a separate visit. If you're planning to add an electric vehicle, mention it at the diagnostic.
Generator interlock or transfer switch. If you're considering a whole-home generator, adding the transfer switch or interlock during the panel replacement reduces total labor cost.
Surge protection. Florida leads the country in lightning strikes. A panel-mounted whole-home surge protector protects every device on every circuit. Easiest to add when the panel is already open.
We tell you the price before anything starts. You say yes or you say no. If you say no, you pay the $89 diagnostic and we leave. That's the deal on every job — no surprises after the fact.

About Anatoliy →Frequently Asked Questions
Do I need to be home for the entire panel upgrade?+
You need to be home at the start to confirm scope and provide access. After that, you can leave. We'll call before restoring power and when the job is complete. The county inspection happens on a separate day — we schedule it, and you don't need to be present as long as the panel is accessible.
Will my power be off all day?+
No. Power is off during the removal and installation stages — roughly three to five hours for a standard job. We restore power before leaving. The county inspection visit, which happens days later, does not require another power interruption.
Will I be without power overnight?+
No. Power is restored on installation day before the crew leaves. We schedule early morning starts — typically 7:00 or 8:00 AM — specifically so power is back well before the afternoon heat peak. If anything unexpected extends the job, we'll tell you before it becomes an overnight issue.
How much does a panel upgrade cost in Tampa Bay?+
A standard 200-amp panel upgrade in Pasco, Hillsborough, or Pinellas County runs $1,800–$3,200 depending on the panel brand, whether the meter base needs replacement, and the number of circuits. The $89 diagnostic produces a fixed written quote before work begins.
Does a panel upgrade require a permit in Florida?+
Yes. Every panel replacement in Florida requires a permit and a county inspection. We pull the permit and schedule the inspection. Permit fees in the three-county area typically run $75–$150.
Is a panel upgrade a messy job?+
No. A standard panel replacement is contained to the panel enclosure and the meter. It doesn't involve cutting drywall or running new circuits through walls unless that work is separately quoted. The crew cleans up before leaving.
What is the difference between a panel upgrade and a service upgrade?+
A panel upgrade replaces the breaker box — the enclosure, main breaker, and individual breakers. The utility feed stays the same. A service upgrade increases the amperage at the utility connection point and requires utility company involvement. Most Tampa Bay homes need a panel replacement, not a full service upgrade. The $89 diagnostic confirms which applies.
Can I install an EV charger or generator during the same visit?+
Yes, and it costs less to combine them. If the panel is already open and the service is already disconnected, adding a generator transfer switch or an EV charger circuit at the same time reduces total labor compared to scheduling two separate jobs. Mention it at the diagnostic.
Will my food spoil during a panel upgrade?+
Power is typically off for three to five hours. The FDA guideline for refrigerator food safety is four hours — a standard job shouldn't create a food safety issue if you keep the refrigerator and freezer doors closed during the outage. A full freezer holds temperature longer than an empty one.
How do I know if I need a new panel or just a new breaker?+
If a single breaker is tripping, it may only need a breaker replacement — a much smaller job. If the panel is Federal Pacific or Zinsco, if breakers are warm to the touch, if you smell burning near the panel, or if your insurer is asking questions about it, a full replacement is likely warranted. The $89 diagnostic tells you which situation you're in.
