How Long Does EV Charger Installation Take?

Short answer: most installations are done in half a day. Schedule your electrician in the morning, and you'll be charging your car by dinner.

Long answer: it depends on your house. Let me walk through what determines whether you're looking at a quick two-hour job or a two-day project.

The Three-Tier Breakdown

I like to think of EV charger installations in three categories. Your job will fall into one of them based on your home's electrical setup and where you want the charger.

Tier 1: The Easy Install (2–3 Hours)

This is the dream scenario. Your electrical panel has open slots, it's in or near the garage, and you want the charger on the wall right there. The electrician shows up, installs a new breaker, runs 20 feet of wire, mounts the charger or outlet, and tests everything.

You get this timeline when:

Your panel is in the garage (or the other side of the garage wall)
The panel has capacity for a new 50A or 60A breaker
The wire run is short — under 25 feet
No drywall, concrete, or exterior walls need to be penetrated
No conduit needs to be run along ceilings or walls

This is common in newer homes with attached garages, where the builder put the electrical panel in the garage (thanks, builder). About 30% of installations fall into this category.

Tier 2: The Average Install (4–6 Hours)

This is where most jobs land. The panel has capacity but it's in the basement, utility room, or on the opposite side of the house from the garage. The electrician needs to run wire through walls, along the ceiling of an unfinished basement, or through a crawl space.

Typical scenarios:

Panel is in the basement, charger is in the attached garage above. Wire goes up through the floor — maybe 40–60 feet of total run.
Panel is on the side of the house, charger is in a detached garage 30 feet away. Wire runs through conduit along the exterior and underground.
Panel is in the garage but the homeowner wants the charger on the driveway or carport. Conduit runs along the garage wall and out to the install location.

The time adds up because of conduit work. Bending conduit, securing it with straps every few feet, pulling wire through it — this is careful, physical work. An experienced electrician makes it look easy, but it still takes time to do right.

Tier 3: The Complex Install (1–2 Days)

Now we're talking about jobs that involve significant additional work beyond just running a circuit.

Panel upgrade: If your home's electrical panel is full (no open breaker slots) or undersized (100A panel that can't handle another 50A load), it needs to be upgraded. A panel upgrade alone is a 4–8 hour job. Your utility may need to disconnect and reconnect power, which requires coordination and sometimes a separate appointment.

Going from a 100A panel to a 200A panel — which is the most common upgrade for EV charging — typically costs $1,500–$3,000 on top of the charger installation.

Long conduit runs: If the charger location is 100+ feet from the panel — common with detached garages — the electrician is spending hours just on the conduit and wire pull. Underground runs require trenching, which adds more time (and cost, if they need to cut through concrete or landscaping).

Difficult access: Old homes with plaster walls, no crawl space, finished basements with no accessible wire routes — these slow everything down. The electrician has to get creative with routing, and creative routing takes time.

Subpanel installation: Sometimes the best solution for a detached garage is running a subpanel. The electrician installs a small secondary panel in the garage, feeds it from the main panel, and then runs the charger circuit from the subpanel. More components, more connections, more time.

What Specifically Takes So Long?

If you're watching your electrician work and wondering why it's taking four hours for what seems like a simple charger, here's where the time goes:

Running conduit: Measuring, cutting, bending, and mounting conduit is the most time-consuming part of most installations. Every bend needs to be precise. Every section needs support brackets. Going through walls means drilling holes and sealing them.

Wire pulling: Pulling 6-gauge wire (typical for a 50A circuit) through 50+ feet of conduit isn't trivial. The wire is stiff and heavy. Pulling it around corners requires technique and sometimes a second person.

Panel work: Opening up the electrical panel, installing a new breaker, landing the wires on the breaker and ground/neutral bars, labeling the breaker — this takes 30–60 minutes even for a straightforward installation. The electrician needs to be careful and methodical here. This is the most dangerous part of the job.

Mounting and finishing: Mounting the charger, making final connections, routing the charging cable, patching any holes, cleaning up — another 30–60 minutes.

Testing: The electrician tests the circuit with a multimeter, verifies voltage and amperage, and then does a test charge with your vehicle. This takes 15–30 minutes.

Factors That Speed Things Up

Want a faster installation? These conditions help:

Panel in the garage with open slots. This alone eliminates hours of work.
Unfinished garage walls. The electrician can surface-mount conduit without worrying about aesthetics or drywall repair.
Short wire run. Every 10 feet of additional distance adds time.
Clear access. Move your cars, clear the area around your panel, and make sure the electrician can get to everything easily. You'd be surprised how often a cluttered garage adds 30 minutes to a job.
Existing 240V circuit. If you have an unused 240V outlet (from an old dryer, welder, or workshop tool), your electrician might be able to repurpose it. This can turn a 4-hour job into a 1-hour job, though the circuit needs to be properly rated.

Factors That Slow Things Down

And these make it take longer:

Panel upgrades. Easily the biggest time addition. Budget a full extra day.
Trenching. Underground wire runs to detached garages require digging a trench (usually 18–24 inches deep per code). If it's through dirt, a trencher makes quick work of it. Through concrete? That's a different story.
Permit inspections. The install itself might take 4 hours, but if your jurisdiction requires the inspector to see the rough-in before you close up walls, you might need the electrician to come back after the inspection for finishing work.
Old homes. Homes built before 1970 often have surprises: undersized panels, aluminum wiring, lack of proper grounding, or knob-and-tube wiring that needs to be addressed before adding a high-amperage circuit.

Planning Your Day

Here's my practical advice for scheduling:

Book a morning appointment. If your electrician starts at 8 or 9 AM, even a complex job is done by late afternoon. An afternoon start risks the job going into the next day.

Plan to be home. You don't need to watch over the electrician's shoulder, but you should be available. They'll have questions: "Which side of the garage do you want the charger?" "Do you care if the conduit is visible here?" "Can I turn off power for 30 minutes?"

Have your car ready. The electrician will want to test-charge your vehicle at the end. Make sure it's accessible and not fully charged (you need room to verify charging starts).

Move your stuff. Clear 3 feet of space around your electrical panel and the charger mounting location. If the wire route goes through a closet or utility room, clear that too.

Don't schedule anything critical for that day. Power will be off for portions of the install. If you work from home, plan accordingly — you might lose power to your office for an hour while the panel work is happening.

The Bottom Line

Installation Type	Typical Duration
Simple (panel in garage, short run)	2–3 hours
Average (panel elsewhere, moderate run)	4–6 hours
Complex (panel upgrade + long run)	8–16 hours (1–2 days)

Most jobs are Tier 2. Your electrician shows up in the morning, works through the midday, cleans up in the afternoon, and you're plugging in your car by 5 PM. It's one of those home improvements that feels like a big deal beforehand and seems simple in hindsight.
