Do You Need 200-Amp Service? The Honest Checklist

You probably need the upgrade if any of these are true:

• You’re adding an EV charger. A Level 2 charger needs a dedicated 40–60 amp circuit. On a 100-amp service that’s already running AC, a dryer, and a water heater, the math usually doesn’t work. This is the #1 reason homeowners request service upgrades right now.
• Your breakers trip when big appliances run together. AC + dryer + oven = tripped main. That’s your service telling you it’s at its limit.
• You’re adding a pool, spa, or hot tub. Pool pumps and heaters are hungry. So are the lights and outlets around them.
• You’re building an addition or finishing space. More square footage means more circuits, more load, more everything.
• You have a workshop or garage with 240V tools. Welders, air compressors, EV chargers in the shop — a 100-amp service wasn’t built for that.
• Your home still has 60-amp service. Common in Plant City’s oldest homes near Historic Downtown. Sixty amps in 2026 isn’t a limitation, it’s a liability — and your insurance company may agree.

You probably don’t need it if: your 100-amp service handles everything fine, you’re not adding major loads, and a load calculation shows headroom. We’ll run the numbers either way. If the answer is “you’re fine,” we’ll say so — we’d rather earn your trust than your money.

What’s Actually Involved in a Service Upgrade

A 200-amp upgrade is a bigger job than a panel swap, because we’re replacing the entire service chain:

1. Load calculation (NEC Article 220). Before anything else, we calculate your home’s actual electrical demand — existing loads plus everything you’re planning. This isn’t guesswork; it’s the National Electrical Code’s prescribed method. The result tells us whether 200 amps is right, or whether your situation calls for something different.

2. New meter base and service conductors. The meter enclosure gets replaced with a 200-amp rated base, and the conductors running from the utility connection to your panel get upsized. This is the part that actually delivers the extra capacity — skip it and you’ve just bought an expensive decoration.

3. New 200-amp panel. The old panel comes out; a new 200-amp main breaker panel goes in — typically Square D QO or Eaton CH, both proven over decades. Every circuit lands on a new breaker, grounding and bonding get verified per NEC Article 250, and everything gets labeled.

4. TECO coordination. Tampa Electric owns everything up to the meter. Upgrading service means coordinating the disconnect and reconnect with TECO, and sometimes utility-side work if their drop or lateral needs upsizing too. We handle that scheduling — it’s one of the parts of the job where local experience matters most, because utility timelines can shift.

5. City of Plant City permit and inspection. Like any service work, the upgrade needs a permit and a city inspection before it’s closed out. We pull the permit, meet the inspector, and hand you the close-out documentation.

6. Power outage planning. You’ll be without power for most of the installation day — usually 6–10 hours for a full service upgrade. We’ll tell you exactly when, so you can plan around it. Fridge stays closed, phones charged, and it’s one day.

100 Amps vs. 200 Amps: What the Numbers Mean in Practice

Amps measure how much electrical current your home can draw at once. Here’s what that means in real terms:

• 60-amp service (oldest Plant City homes): enough for lights, a fridge, and not much else. Dangerous to stretch.
• 100-amp service (most mid-century homes): handles a typical home if you’re not stacking big loads. Add an EV charger or a hot tub and you’re over.
• 200-amp service (modern standard): comfortable headroom for AC, electric appliances, EV charging, a workshop, and whatever comes next. This is what new construction gets, and it’s what your home should have if you’re upgrading.

The key insight: it’s not about using 200 amps today. It’s about never having to think about it again. An upgrade is a decades-long decision.

Plant City Specifics: Why This Comes Up So Often Here

Service upgrades are more common in Plant City than many homeowners expect, and it’s not a coincidence:

• The housing stock. Homes around Historic Downtown and the older corridors were built when 60-amp and 100-amp services were standard. The houses are solid — the electrical services just predate modern life.
• Rural lots, big ambitions. Out in Trapnell and Turkey Creek, properties have detached workshops, barns, and well pumps. A 100-amp service feeding a house plus a workshop with 240V equipment was never going to work long-term.
• The EV wave. Plant City commuters are buying EVs, and every Level 2 charger installation starts with the same question: does the service have room? Often, it doesn’t.
• Storm resilience. After a hurricane-season outage, a lot of homeowners start asking about whole-home generators. A generator interlock or transfer switch usually pairs with a service evaluation — and often an upgrade.

Frequently Asked 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.

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.

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 one of the most common ways homeowners waste money on electrical work. 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.
