Electrical Panel FAQs — Plant City, FL

Real answers to the questions Plant City homeowners ask about their electrical panels. For anything else, call (813) 471-5214.

General panel questions

Can I replace my electrical panel myself?
No — and this isn’t a sales pitch, it’s a safety fact. The main lugs stay live even with the main breaker off, and one mistake can kill you. Florida requires a licensed electrician and a permit for this work.

How do I know if my panel is a Federal Pacific or Zinsco?
Open the panel door and look at the breaker labels — Federal Pacific panels say “Stab-Lok” and often have red-tipped breakers; Zinsco panels are labeled Zinsco or GTE-Sylvania. Both were common in homes built from the 1950s through the 1980s.

Cost questions

How much does electrical panel replacement cost in Plant City, FL?
Most residential panel replacements fall between $1,800 and $3,500, depending on amperage, panel location, and the condition of the existing wiring. After an on-site assessment you get a firm written number. See panel replacement for details.

How much does it cost to replace a single circuit breaker?
The breaker itself runs $15–$40; with the service visit and safe installation, most single-breaker replacements total $150–$300 in the Plant City area.

Is it cheaper to repair or replace an electrical panel?
Repairs run $150–$500; full replacement runs $1,800–$3,500+. Repair wins when the problem is isolated. Replacement wins when repairs keep recurring or the panel itself is the hazard (age, brand, bus damage).

How much does it cost to upgrade electrical service to 200 amps?
In the Plant City area, typically $2,500–$4,500 for a full 100-to-200-amp upgrade including panel, meter base, conductors, permit, and inspection. Underground services or difficult routing can push higher. See 200-amp service upgrades.

Repair questions

Can you just replace one breaker instead of the whole panel?
Yes — if the breaker failed and the bus bar and panel enclosure are healthy. If the bus bar is corroded or the panel is a Federal Pacific or Zinsco, a single-breaker swap doesn’t solve the real problem.

Why does my breaker keep tripping?
Three usual suspects: an overloaded circuit, a worn-out breaker tripping below its rating, or a short/ground fault. Trips instantly on reset points to a fault or dead breaker; trips when multiple appliances run points to overload.

My breaker won’t reset. What should I do?
Push it fully to OFF, then firmly to ON. If it trips again immediately, stop — don’t force it. That’s the breaker protecting you from a short circuit or telling you it has failed. Call an electrician.

Is a buzzing breaker box dangerous?
Buzzing or crackling is a warning sign — it usually indicates a loose connection arcing inside the panel. A faint hum under heavy load can be normal, but audible buzzing or crackling deserves prompt professional attention.

What should I do if I smell burning near my electrical panel?
If you can safely reach it, turn off the main breaker. Don’t touch anything scorched or melted. Call an electrician right away — and if there’s smoke or flame, call 911 first.

Can I change a 15-amp breaker to a 20-amp breaker myself?
Only if the circuit wiring is 12 AWG — a 20-amp breaker on 14 AWG wire is a code violation and a fire hazard. And panel work isn’t DIY regardless: the lugs stay live even with the main off. Have a licensed electrician do it.

Replacement questions

How long does it take to replace an electrical panel?
The physical swap takes 4–8 hours, with your power off for most of the workday. Permits and the city inspection add a few days to the overall timeline, but you’re only without power on installation day.

Do I need a permit to replace an electrical panel in Plant City, FL?
Yes. The Florida Building Code requires a permit for panel replacement, and the City of Plant City inspects the work before the job is closed. We handle the permit and inspection scheduling as part of the job.

Will my insurance require me to replace a Federal Pacific or Zinsco panel?
Very likely. Many Florida carriers decline new policies or require replacement of Federal Pacific Stab-Lok or Zinsco panels, and 4-point inspectors flag them routinely — but each insurer sets its own rules, so check with your carrier.

What’s the difference between replacing a panel and upgrading service?
Replacing the panel swaps the breaker box, usually at the same amperage. Upgrading service increases your home’s total electrical capacity — new meter base, larger conductors, utility coordination.

Should I add whole-home surge protection with a new panel?
In Central Florida, yes. Central Florida sees some of the most lightning in the country, and a Type 2 surge device at the panel is inexpensive protection for every appliance and electronic device in the house.

200-amp upgrade questions

Is upgrading from 100 amp to 200 amp worth it?
If you’re adding an EV charger, remodeling the kitchen, adding central AC or a hot tub — yes, almost certainly. If nothing’s changing and the load calculation shows headroom, save your money. The calculation decides, not a sales pitch.

Can I just put a 200-amp panel on my 100-amp service?
You can physically do it, but you won’t get 200 amps — the service conductors and meter base still limit you to 100. It’s the most common waste of money we see. The service has to be upgraded as a system.

Do I need a panel upgrade to install an EV charger?
A Level 2 EV charger needs a dedicated 40–60 amp circuit. If your panel is full or your service is 100 amps with little headroom, an upgrade is likely. Start with a load calculation — it takes the guesswork out.

Can I add more breakers instead of upgrading?
Only if the panel has physical space and the load calculation shows the service can handle the added load. Tandem breakers can add circuits, but they don’t add capacity. If the service is maxed out, more breakers just move the problem.

How long does a service upgrade take?
The installation itself is usually one full day (6–10 hours) with power off most of that time. Permits, TECO scheduling, and the city inspection stretch the total timeline to 1–3 weeks, but you’re only without power on install day.

Will TECO need to do work on their side?
Sometimes. If the utility drop or lateral serving your home can’t carry 200 amps, TECO upgrades it on their schedule — usually at the utility’s cost, though that can vary. We coordinate with them so it doesn’t stall your project.
