Panel Upgrades: When Your Tampa Home Has Outgrown Its Electrical Service
A lot of Tampa Bay's housing stock still runs on 60 or 100-amp panels installed decades before central air, EVs, and home offices existed.
How to Tell Your Panel Is Undersized
Breakers that trip when you run the microwave and the AC at the same time, warm spots on the panel cover, or a panel with fewer than 20 open slots are all red flags. Homes built before 1990 in areas like Sulphur Springs, Temple Terrace, and Seminole Heights commonly started with 60 or 100-amp service. Today's homes with central air, an EV charger, and a kitchen full of appliances need 150 to 200 amps to run without strain.
What the Upgrade Actually Involves
A panel upgrade means replacing the box, the main breaker, and often the service entrance cable running from the meter. In Hillsborough and Pinellas counties this requires a permit and an inspection, and depending on your utility you may need to schedule a temporary disconnect. Most upgrades take a single day. Expect the price to shift based on whether your meter can and panel location, plus whether the service entrance wire needs replacing too.
Why It Matters Beyond Convenience
An overloaded panel isn't just inconvenient, it's a fire risk. Breakers that are too small for the load run hot, and connections that have corroded over 40 years of Florida humidity don't grip wires the way they should. If you're planning to add a generator, EV charger, or pool, get the panel evaluated first. Adding those loads to an undersized panel is one of the most common reasons Tampa homeowners end up with an electrical inspection failure at resale.
