What to Expect on EV Charger Installation Day

April 10, 2026

Installation Day: What Actually Happens

You've picked your charger, scheduled the install, and now the day is here. If you've never had major electrical work done at your home, you might be wondering what to expect. We do these installations every day, but we remember that for most homeowners, this is a first-time experience.

Here's an hour-by-hour walkthrough of a typical EV charger installation in an Orlando-area home, from the moment we pull into your driveway to the moment you plug in your car for the first time.

Before the Electrician Arrives

A few things to take care of the morning of your install:

Clear the work areas. Move anything away from your electrical panel (both sides , the installer needs to open it). If the charger is going in the garage, make sure there's room to work. If it's an outdoor install, clear any patio furniture or planters from the mounting area.
Make sure your panel is accessible. We need clear access to the main electrical panel and at least 36 inches of working space in front of it (that's code, not preference).
Park your EV where it'll charge. This helps the installer confirm the cable will reach your car's charge port from the planned charger location.
Secure pets. We'll have doors open and tools on the floor. A curious dog and an open panel breaker aren't a good combination.
Be home (or have someone home). We need access to the panel, which is usually inside. And decisions sometimes come up during the install that only the homeowner can make.

Typical Arrival Window

We schedule installations in morning or afternoon blocks. You'll get a text or call when the installer is 30 minutes out. Most installs start between 8 and 10 AM , we prefer morning starts in Florida because garages and attics become ovens by early afternoon in summer.

Phase 0: Arrival and Walkthrough (15 to 20 Minutes)

The electrician arrives, introduces themselves, and does a walkthrough of the job. Even though we've usually done a prior site assessment (in person or from photos), the installer verifies everything fresh. Things can change between the assessment and install day.

During the walkthrough, the installer will:

Confirm charger placement. "You wanted it here on this wall, right? The cable will reach your charge port from here." Sometimes homeowners change their minds , now is the time.
Inspect the electrical panel in person. Open it up, verify available space, confirm the wire gauge matches the planned breaker size, and check that the bus bar has open slots.
Discuss conduit routing. "Here are your options for running the wire from the panel to the charger. Option A goes through the attic , cleaner look but takes longer. Option B runs surface conduit along this wall , faster and slightly cheaper." The installer will explain the pros and cons and let you choose.
Point out any surprises. Occasionally, something comes up that wasn't visible in photos: a panel that's more crowded than expected, an unexpected wall obstruction, or a longer-than-anticipated conduit run. The installer will discuss any scope changes and cost implications before starting work.

Once you've agreed on the plan, the installer unloads tools and materials, lays down drop cloths in work areas, and gets started.

Phase 1: Panel Work (30 to 45 Minutes)

Power Shutdown

The installer turns off the main breaker to safely work inside the panel. Your entire home will be without power for 20 to 40 minutes during this phase. If you're working from home, save your documents and let your laptop switch to battery. Notify anyone else in the house.

In summer, this means your AC stops temporarily. The house stays comfortable for 30 to 40 minutes , you won't notice much temperature change. If you have a fish tank, aquarium heater, or medical equipment that can't lose power, let the installer know beforehand so they can plan accordingly.

Breaker Installation

With the panel de-energized, the installer removes the panel cover and installs a new dedicated breaker , typically a 50-amp or 60-amp double-pole breaker. This involves:

Snapping the breaker onto the bus bar
Routing the new circuit wires into the panel through a knockout hole
Terminating the hot wires (typically two black or one black/one red) on the breaker terminals
Terminating the neutral wire on the neutral bus bar
Terminating the ground wire on the ground bus bar
Torquing all connections to manufacturer specifications , this is critical for safety and required by NEC 110.14(D). Under-torqued connections cause heat buildup and are a leading cause of electrical fires. Your installer uses a calibrated torque wrench or torque screwdriver.

The new breaker gets labeled (usually "EV CHARGER" or "EV CHARGER, GARAGE") on the panel schedule.

Power Restoration

Once the panel work is complete and the cover is back on, the installer turns the main breaker back on. Your home has power again. The new EV breaker stays OFF until the charger is fully installed and ready to test.

Phase 2: Conduit and Wire Run (1 to 2 Hours)

This is the longest phase of the installation, and it's where most of the physical labor happens. The installer is building the pathway that carries wire from your panel to the charger location.

Why This Takes the Longest

Running conduit involves measuring, cutting, bending, mounting, and connecting multiple sections of conduit. Each connection needs to be secure and , for outdoor runs , weatherproof. Then the wire has to be pulled through the entire length. In a best case (panel and charger on the same wall, 10 feet apart), this takes 30 minutes. In a typical case (panel in garage, charger on opposite wall, 20-30 feet), it's 60 to 90 minutes. In a complex case (panel inside, charger outside across the house, 50+ feet with attic or underground runs), it can take 2 hours or more.

Common Routing Methods in Central Florida Homes

Surface mount on interior garage walls: The most common approach. EMT (electrical metallic tubing) or PVC conduit runs along the wall surface from the panel to the charger location. We mount it with straps every 4 feet, keeping it tight to the wall and as unobtrusive as possible. In a garage, this is the fastest and most cost-effective option.

Through-wall penetration: When the panel is on one side of a wall and the charger is on the other (common for outdoor installations), we drill through the wall and seal the penetration. For CBS (concrete block) construction , which is about 80% of Orlando homes , this means drilling through 8 inches of solid block with a core bit. It's loud, it creates dust (we contain it with plastic sheeting), and it takes about 10 minutes per hole.

Attic runs: For longer distances where surface conduit would be ugly, we run wire through the attic. This gives a clean look , conduit drops down from the ceiling at the panel and again at the charger location, with the wire hidden above the drywall in between. The tradeoff: attic work in Florida summers is physically demanding. Attic temperatures can exceed 140°F. Our installers take breaks and stay hydrated, which can add time.

Underground runs: Used when the charger is across a driveway or in a detached structure. Trenching, laying conduit, backfilling, and restoring the surface. This adds the most time , typically 2 to 3 hours for the underground portion alone.

What the Finished Conduit Looks Like

A professional conduit run should look intentional, not like an afterthought. Conduit runs level and plumb , horizontal sections are truly horizontal, vertical sections are truly vertical. Bends are smooth and consistent. Mounting straps are evenly spaced. Where conduit crosses a visible area, it's routed along natural lines of the architecture (following wall edges, running above door frames, etc.).

If you want the conduit painted to match your wall, let the installer know. We can leave it unpainted (silver EMT or gray PVC) or paint it during the install. Most homeowners in garages leave it as-is. For outdoor installations, we typically paint PVC to match the exterior wall color , it makes a significant difference in appearance.

Wire Pulling

With the conduit in place, the installer pulls the circuit wires through. For a typical 50A EV circuit, that's three 6-gauge THHN conductors (two hots and a neutral) plus a ground wire. Wire pulling is usually a quick process , 10 to 15 minutes , unless the run is very long or has multiple tight bends. Long runs sometimes require two people or a fish tape to guide the wire through.

Phase 3: Charger Mounting and Connection (30 to 45 Minutes)

Mounting

The installer marks the mounting holes, drills into the wall, and secures the charger's mounting bracket. The approach varies by wall type:

Concrete block: Hammer drill + Tapcon screws. Rock solid.
Wood studs (drywall over wood framing): Stud finder to locate studs, then lag screws directly into framing. If studs don't line up with the charger's mounting holes, a plywood backer board gets installed first.
Stucco over block: Same as concrete block , the screws go through the stucco into the block. Stucco gets patched around the penetrations.

Wire Termination

The installer strips the wire ends, connects them to the charger's terminal block, and torques each connection. This is where precision matters. The hot wires connect to Line 1 and Line 2 terminals, the neutral to the neutral terminal, and the ground to the ground terminal. Some chargers (like the Tesla Wall Connector) don't use a neutral , just two hots and a ground.

Strain Relief

Where the wires enter the charger, a strain relief connector prevents the wire from being pulled or stressed at the termination points. This is a code requirement, not optional. The installer installs a cable clamp or strain relief fitting and tightens it securely.

Phase 4: Testing and Commissioning (15 to 30 Minutes)

Now comes the satisfying part. The installer turns on the dedicated breaker and brings the charger to life.

Voltage Verification

Using a multimeter, the installer checks voltage at the charger terminals. They're looking for 240 volts (±5%) between the two hot legs, 120 volts between each hot leg and neutral/ground, and 0 volts between neutral and ground. Any significant deviation means something needs to be corrected before proceeding.

Ground Fault Testing

EV chargers have built-in GFCI (ground fault circuit interrupter) protection. The installer tests this by pressing the charger's self-test button and verifying that the unit trips and resets correctly. This safety feature prevents electric shock in the event of a ground fault , critical for a device you'll touch with wet hands on a rainy Florida evening.

First Vehicle Charge

The installer plugs your vehicle in for the first time and confirms:

The car recognizes the charger and begins charging
The charger displays the correct amperage (matching its configuration)
Charging speed matches expectations , for a 48A charger at 240V, you should see approximately 11.5 kW or about 40-44 miles of range per hour, depending on your vehicle
No error codes on either the charger or the vehicle's dashboard

Smart Charger Setup

If you have a smart charger, the installer helps you connect it to your Wi-Fi network and download the app. They'll walk you through the basic features , how to check charging status, set a schedule, and review energy usage. This typically takes 5 to 10 minutes.

Phase 5: Cleanup and Handoff (15 Minutes)

The installer cleans up all debris , wire scraps, conduit shavings, concrete dust from drilling, packaging materials. The work area should look as clean as (or cleaner than) when they arrived.

Final Walkthrough

The installer walks you through the completed installation:

Shows you the conduit run and explains the routing
Points out the dedicated breaker in your panel and its label
Demonstrates how to plug in and unplug the charger
Reviews the charger's LED status indicators (what green, blue, red, and flashing lights mean)
Explains basic troubleshooting: "If the charger shows a red light, first try flipping the breaker off and on. If that doesn't fix it, call us."

Documentation

Warranty information: Most chargers carry 3 to 5 year manufacturer warranties. The installer provides this paperwork or directs you to register online.
Permit card: If the installation required a permit (most do in Orange County, Osceola County, and City of Orlando jurisdictions), a permit card is posted near the panel. The inspector will need to see this.
Invoice and receipt: For your records and for potential federal tax credit claims (the 30C credit covers up to $1,000 for residential EV charger installation).
Contact information: Direct line for questions or issues. We don't disappear after installation.

What a Complex Installation Looks Like

The timeline above is for a standard installation , panel and charger in the same garage, reasonable conduit run, no panel upgrade needed. Complex installations take 4 to 6 hours (sometimes spread over two visits) and include scenarios like:

Panel upgrade + charger installation: Replacing the entire panel adds 2 to 3 hours.
Long underground conduit run: Trenching across a driveway adds 2 to 3 hours.
Attic run in summer: Heat breaks slow things down. A 1-hour attic run might take 1.5 hours.
Sub-panel installation: Sometimes we install a small sub-panel near the charger location instead of running a long home-run cable. Adds 1 to 2 hours.
Stucco repair and painting: If exterior conduit needs to match the house color, add 30 to 60 minutes for paint and dry time.

Real Scenario: A Typical Install in Laureate Park

A 2020 townhome in Laureate Park (Lake Nona area). Three-story layout, single-car garage, 200A panel on the first floor in a utility closet under the stairs. Charger location: right side of the garage wall, about 15 feet from the panel. The homeowner wanted a Tesla Wall Connector for their Model Y.

Here's how the day went:

8:15 AM: Installer arrived, did the walkthrough. Panel was in great shape , 8 open slots, plenty of capacity. Routing plan: conduit through the utility closet wall into the garage, along the garage ceiling, down to the charger mount.
8:40 AM: Panel work began. Main breaker off. 60A breaker installed, wires landed, torqued, panel cover back on. Main breaker back on by 9:10 AM. Total outage: 30 minutes.
9:15 AM: Conduit work started. Drilled through the block wall between utility closet and garage (the dusty part). Ran EMT conduit along the garage ceiling , about 12 feet horizontal, then a 90-degree bend down the wall to the charger height. Three mounting straps, two connectors, one junction box. Pulled wire through. Done by 10:30 AM.
10:30 AM: Mounted the Tesla Wall Connector on the garage wall. Terminated wires , two hots and a ground (no neutral needed for the Tesla unit). Tightened everything to spec.
11:00 AM: Powered on, tested voltage (242V , perfect), ran the ground fault test, plugged in the Model Y. Charger showed 48 amps, car displayed 44 miles per hour of charge. Set up the Tesla app. Everything working.
11:15 AM: Cleanup, walkthrough, paperwork. Done by 11:30 AM.

Total time on site: 3 hours 15 minutes. Total cost: $1,850 (including the Tesla Wall Connector, all materials, labor, and permit fees).

After the Installer Leaves

Once the installation is complete:

Do a full charge cycle. Plug in and charge your car from its current level to full. This confirms everything works through a complete session, not just a 10-minute test.
Check your charger app (if smart charger) and make sure it shows accurate data , energy delivered, charging speed, session history.
Set up your charging schedule if you're on a time-of-use electricity plan. Program off-peak charging right away so you start saving from day one.
Take photos of the installation , the charger, the conduit run, and the breaker label. Good to have for your records, insurance documentation, or if you ever sell the house.
Register your charger warranty with the manufacturer. Most require online registration within 30 to 60 days of purchase.

When to Expect the Inspection

If your installation required a permit (and in most Central Florida jurisdictions, it does), an electrical inspector will need to sign off on the work. Here's how it typically works:

Your installer schedules the inspection with the local building department , you don't need to do this yourself.
Orange County inspections are typically scheduled within 3 to 5 business days after the work is completed.
Someone needs to be home to give the inspector access to the panel and charger. The inspection itself takes about 15 minutes.
The inspector checks the breaker size, wire gauge, conduit installation, charger mounting, and ground fault protection. They'll sign or stamp the permit card.
If anything doesn't pass, the installer comes back and corrects it at no additional charge , and a re-inspection is scheduled.

In our experience, well over 95% of our installations pass on the first inspection. The most common inspection notes (when they occur) are minor: a missing label on the breaker, or a conduit strap that needs to be added. Nothing that affects your ability to use the charger in the meantime.
