What Happens During a Home EV Charger Installation, Step by Step

Most people have never had an EV charger installed, so it helps to know what the job looks like from the first call to the moment the car starts charging. A permitted home installation in South Florida follows the same basic sequence almost everywhere: a look at the home, a check that the electrical service can carry the load, a permit, the installation, an inspection, and a handoff where the charger is set up and explained.

How long each step takes depends on the house, the city's building department and whether other approvals (a condo board, an HOA, the utility) are involved, so we do not promise durations here. This guide walks through each step, what happens and what you can do to keep it moving. It is part of our Florida Home EV Charging Guide.

Step 1: the first conversation

The quickest way to a useful answer is a few photos. Before anyone visits, we usually ask for:

• The main panel with its door open, and the label inside the door showing the brand and rating.
• The main breaker, so we can read its amperage.
• The meter, and where it is on the house.
• The spot where you would like the charger, and where you park.
• The car's make and model, and the charger if you have already bought one.

Those photos often show right away whether the job is simple or whether the panel is the real project. If you live in a condo or an HOA community, mention it now; it changes the order of the steps (see Step 4).

Step 2: the site visit

On site, the electrician looks at three things.

1. The location. Where the car's charge port is, how the cable will reach, the mounting height the manual calls for, and anything in the way. Details in where to install an EV charger in the garage and driveway, carport and pedestal chargers.
2. The route. How the circuit gets from the panel to the charger: through the attic, along a block wall in conduit, or underground to a pedestal.
3. The panel and service. Whether there is physical space for a two-pole breaker, what else is on the panel, the condition of the equipment and the service size.

Outdoors, the visit also covers exposure to rain, sun and salt air (outdoor chargers in Florida), and on low lots, flood risk (flood zone mounting).

Step 3: the load check

A Level 2 charger is a large, continuous load. NEC 625.41 requires the breaker to be sized at not less than 125% of the charger's maximum load, so a 40 A charger needs at least a 50 A breaker (Mike Holt Article 625 notes). The question is whether the existing service can carry that on top of the air conditioning, water heater, range and pool pump.

There are two common ways to answer it. One is a load calculation from the home's equipment. The other, under NEC 220.87, uses 12 months of maximum-demand data for the existing service (code text summary), which your utility may be able to provide. The result points to one of three paths: install at the charger's full rating, install at a lower setting, or address the panel with an upgrade or load management. See load management vs panel upgrade and how many amps an EV charger needs.

If the charger has adjustable output, NEC 625.42 allows the adjusted setting to be treated as its rating when access to the setting is restricted, for example by a password-protected app or a cover that needs a tool (code text summary). Tesla's Gen 3 Wall Connector, for example, pairs each breaker size with an output setting, from a 60 A breaker at 48 A down to a 15 A breaker at 12 A (Tesla breaker table).

Step 4: approvals and the permit

An electrical permit is required. Miami-Dade County states that "an electrical permit is required for electrical work" for unincorporated areas (Miami-Dade electrical permits), and each municipality has its own building official (Miami-Dade permit process). Some cities publish EV-specific submittal checklists; Pompano Beach has one for vehicle charging stations (Pompano Beach checklist). Under the state's Rule 5J-28, local governments may still require electrical permits and inspections for chargers, and must approve or deny a complete application within 90 days, flagging errors within 30 days (Rule 5J-28). On our jobs, we pull the permit and schedule the inspection.

If you live in a condominium, Florida law says the association cannot prohibit an owner from installing a charger in their limited common element or exclusively designated parking area, but it may require things like a licensed installer, reasonable architectural standards and a certificate of insurance naming the association (F.S. 718.113). Those approvals usually come before the permit. See condo board approval steps. HOA rules depend on the governing documents; see Florida HOA EV charger rules.

Step 5: installation day

What happens on the day, in order:

1. Walkthrough. The electrician confirms the charger location, height and route with you before drilling anything.
2. Power off. The panel is de-energized while the breaker is installed. Plan for the house, or part of it, to be without power for part of the visit, and tell us about anything that must stay on.
3. Mounting. The charger or receptacle is mounted per the manufacturer's instructions.
4. The circuit. Conduit and conductors are run from the panel to the charger. Under NEC 625.40 the charger gets its own branch circuit with no other outlets (code text summary).
5. Terminations. Connections at the breaker and the charger are made and tightened to the specified torque.
6. Labeling. The new breaker is labeled in the panel directory.
7. Power on and test. The charger is powered and tested with your car if it is home.

If a panel upgrade is part of the project, it is its own stage with its own coordination with the utility. See EV charger panel upgrade.

Step 6: the inspection

The building department's inspector checks the work against the code and the permit. Depending on the job, that can include the breaker and wire size, the circuit, the mounting, GFCI protection for a plug-in charger under NEC 625.54 (code text summary) and, for underground runs, the trench and conduit. Some departments want to see an open trench before it is backfilled, so a pedestal job can involve more than one inspection visit. If the inspector asks for a correction, the contractor makes it and the inspection is scheduled again.

Step 7: the handoff

• Setup. Connecting the charger to Wi-Fi and its app, updating firmware, and confirming the output setting matches the breaker.
• Scheduling. Setting the car or charger to charge overnight. If you are on an FPL time-of-use rate, see FPL EV rates and off-peak charging.
• The basics. Which breaker feeds the charger, how to reset it, how to dock the connector, and what a fault light means.
• Paperwork. Keep the permit record with your house documents; it helps when you sell.

How to help it go smoothly

1. Send clear panel and location photos up front.
2. Decide on the charger before the site visit, or ask for a recommendation.
3. Start condo or HOA approvals early.
4. Clear the wall and the path to the panel before installation day.
5. Have the car home on installation day so it can be tested.
6. Check the contractor's license on the DBPR license lookup. See hiring an EV charger installer in Florida.

Questions homeowners ask

How long does an EV charger installation take?

It depends on the route, the panel, the permit timeline in your city and any condo or HOA approvals. A straightforward garage install and a pedestal with a trench across a driveway are very different jobs. After the site visit we can tell you what your job involves.

Do I need to be home?

For the walkthrough at the start and the handoff at the end, it helps. In between, someone needs to provide access to the panel and the charger location.

Can I install the charger myself and just have it inspected?

Florida's electrical owner-builder exemption lets an owner act as their own electrical contractor on their own single-family home or duplex, for their own use, under conditions, including personally appearing to sign the permit application (F.S. 489.503). It does not cover anyone the owner hires, and Florida's Rule 5J-28 says charging equipment shall be installed by a certified or registered electrical contractor (Rule 5J-28). How the two fit together is unsettled, so ask your building department before planning a DIY install. See DIY EV charger installation in Florida.

What if my panel does not have room?

Then the load check points to a lower charger setting, load management or a panel upgrade. See does my panel have room for an EV charger?.
