Which breaker, which charger: the EV charging power ladder

EV charging counts as a continuous load under the National Electrical Code, so a charger may only draw 80% of its breaker's rating. That rule sets how fast your car can charge at home. The power figures below come from Tesla's Wall Connector installation manual; other brands follow the same 80% rule.

Breaker	Max charging current	Power at 240 V	Hookup	Good fit for
60 A	48 A	11.5 kW	Hardwired only. Tesla specifies minimum 6 AWG, 90 °C copper for full power.	Tesla Wall Connector at full output; other 48 A wall units
50 A	40 A	9.6 kW	Hardwired, or a NEMA 14-50 outlet with GFCI protection	The most common home setup; many portable cords top out here
40 A	32 A	7.6 kW	Hardwired or a 240 V outlet rated for the circuit	A good fit when the panel is tight on space or capacity
30 A	24 A	5.7 kW	Hardwired or a 240 V outlet rated for the circuit	Older panels, long wire runs or a second car
20 A	16 A	3.8 kW	Hardwired or a 240 V outlet rated for the circuit	Minimum Level 2; still faster than a 120 V cord

Your car's own onboard charger also has a limit, so a bigger circuit than the car can use adds cost without adding speed. We check the car's charging spec before we size the circuit. Sources: Tesla Gen 3 Wall Connector installation manual and U.S. Department of Energy, charging at home.

Hardwired charger or a NEMA 14-50 outlet?

Both work. The right one depends on your car, your panel and where you park.

Hardwired wall charger

Can run up to 48 A on a 60 A circuit, the fastest home option.
No plug to wear out, which suits a charger used every night.
Tesla's manual calls for a standard two-pole breaker, not a GFCI breaker, at full power.

NEMA 14-50 outlet

Lets you plug in a portable cord, usually up to 40 A on a 50 A circuit.
Easy to move to a new car or a different brand of charger.
Under the 2020 NEC that Florida enforces, every receptacle installed for EV charging needs GFCI protection (NEC 625.54).

Florida's 8th Edition Building Code adopted the 2020 NEC with no state amendments (NEMA code alert, Florida).

Will your panel handle an EV charger?

Most homes can add a Level 2 charger without a new panel. Before you buy one, James runs a load check: what the panel is rated for, what is already on it, and what the new circuit adds. Homes that already run a pool pump, a tankless water heater or a hot tub use more of the panel, so the check matters there.

Room and capacity: the charger fits as is. It gets its own circuit.
Tight on capacity: a smaller circuit from the ladder above, or a charger set to a lower current.
No room, or an older panel: a panel replacement (10-year, 100% parts and labor warranty) or a service upgrade, coordinated with Duke Energy Florida.

Much of Pinellas County's housing is older: about 52% of housing units in unincorporated Pinellas were built before 1980 (Pinellas County Comprehensive Plan, Housing Element, 2006 data). If your panel is a Federal Pacific or Zinsco, or it has scorched breakers, it is better to deal with that before adding a charger. Our panel guide explains the options.

Permits for EV chargers in St. Petersburg and Pinellas County

A new charger circuit is permitted work. The City of St. Petersburg's list of electrical work that may skip a permit covers repairs and like-for-like swaps such as reinstalling a receptacle, not new 240-volt circuits. Outside the city limits, the permit comes from the city where the home sits, or from Pinellas County for unincorporated areas such as Palm Harbor.

Who pulls it: Tailwind Electric, under Florida Certified Electrical Contractor license EC13016047.
Who inspects: the city or county building department. We book the inspection.
Why it helps you: a permitted, inspected circuit is on record if your insurer or a future buyer asks.

Duke Energy's off-peak charging credit

If Duke Energy Florida is your utility, a Level 2 charger can earn you a bill credit. Duke's Off-Peak Charging Credit pays eligible residential customers $7.50 a month for charging during off-peak hours, with up to two EVs per account:

Weekdays: 10 a.m. to 6 p.m., and 11 p.m. to 5 a.m.
Weekends and holidays: any time.
Requirement: a Level 2 charger. A 120-volt cord does not qualify.

Charging outdoors in a coastal Pinellas home

When you park in a driveway or carport, the charger goes on an outside wall or a post. Salt air, sun and summer storms are hard on equipment, so we follow three rules:

Use a charger and outlet the manufacturer rates for outdoor use, and keep the cord off the ground.
Mount it as high as the cord allows on homes in a flood zone, and away from where water collects.
Add whole-home surge protection at the panel. Florida sees a lot of lightning, and a charger is a costly thing to lose.

What an EV charger install looks like

Look and load check: James looks at the panel, the parking spot and the route for the wire, and checks your car's charging spec.
Quote: one price, and what could change it (a long run, a full panel or a wall that is hard to get through).
Permit: filed under EC13016047.
Install: a dedicated circuit, the charger or outlet mounted, everything labeled and tested with the car if it is home.
Inspection and warranty: we meet the inspector, and the work carries our 5-year, 100% parts and labor warranty.

Three 240-volt jobs from our reviews

240-volt garage circuit and outlet

A homeowner asked for a 240-volt circuit and receptacle in the garage. James came out, got the details, quoted it and scheduled it for the next day.

"His vehicle, workmanship, and knowledge of electrical work are all top notch." — Dan, Google

1940s St. Pete house: new panel

A complete panel replacement on a 1940s St. Petersburg home, plus wiring for a tankless water heater and a continuous exhaust fan.

"James presented options, including the pros and cons of each." — Google review

Tankless water heater wiring

Another high-current 240-volt appliance on its own circuit. The homeowner says it was done quickly and works perfectly.

"He wired our tankless water heater and did an awesome job." — Feliks M., Google

More on our reviews page. Related work: tankless water heater wiring, pool and hot tub wiring, breaker repair and whole-home generators.

EV charger installation questions

How much does it cost for an EV charger to be installed?

It depends on three things: how far the charger is from your panel, the amperage you want, and whether your panel has room for a new 240-volt circuit. James quotes after looking at your panel and the parking spot, and tells you what could change the price before you approve.

Do you need a permit to install an EV charger in St. Petersburg?

Yes, in practice. A new 240-volt circuit is not on the City of St. Petersburg's list of electrical work that can skip a permit, so the charger circuit is permitted and inspected. Tailwind Electric pulls the permit under license EC13016047 and books the inspection.

Can I just plug my EV into a 240V outlet?

Yes, if the outlet is the type your charging cord is made for (often a NEMA 14-50) and it is on its own correctly sized circuit. Under the 2020 National Electrical Code that Florida enforces, every receptacle installed for EV charging also needs GFCI protection. A dryer or welder outlet that shares a circuit is not the same thing.

Are there any current EV incentives available in Florida?

Duke Energy Florida runs an Off-Peak Charging Credit of $7.50 a month for eligible residential customers who charge with a Level 2 charger during off-peak hours, for up to two vehicles per account. Check eligibility with Duke Energy before you enroll.

Will an EV charger work with my older St. Petersburg panel?

Often, yes. We run a load check first. If the panel has room, the charger gets its own circuit. If it does not, the options are a smaller charger, load management, a panel replacement or a service upgrade, and we explain each before you choose.

Is it worth it to install a Level 2 charger?

For most daily drivers, yes. A Level 2 charger runs on 240 volts and charges far faster than the 120-volt cord that comes with most cars. It also lets you join Duke Energy's off-peak credit, which requires a Level 2 charger.
