The Complete EV Charger Installation Checklist (Before Your Electrician Arrives)

Your electrician's time costs $75 to $150 per hour. Every question you can answer before they arrive saves money, and every decision you make in advance prevents a second visit. Here's exactly what to have ready so a 3 to 4 hour job doesn't turn into two half-day appointments.

Before You Call the Electrician

1. Know your electrical panel specs

Open your electrical panel (the metal box, usually in the garage, basement, or utility closet). Look for:

• Main breaker amperage: Usually 100A, 150A, or 200A, stamped directly on the main breaker
• Available breaker slots: Count empty spaces; a double-pole 50A or 60A breaker for the charger needs 2 open slots
• Panel brand: Note the manufacturer (Square D, Siemens, GE, Eaton) so the electrician can confirm compatible breakers ahead of time instead of discovering a discontinued model on site

2. Measure the distance from panel to charger location

The farther the wire run, the more the job costs. Measure from your electrical panel to where you want the charger mounted, following the likely path (along a wall, through the attic, around a corner), not a straight line. Every 10 feet of additional wire run typically adds $50 to $100 to the installation. If the run is over 50 feet, the electrician may need thicker gauge wire (6 AWG instead of 8 AWG for a 50A circuit, for example) to prevent voltage drop, which adds material cost on top of the labor.

3. Decide where to mount the charger

Consider:

• Where your car's charge port sits when parked in its usual spot
• Cable reach; most Level 2 chargers ship with an 18 to 25 foot cable
• Mount height; chest height (roughly 45 to 48 inches) is the standard for comfortable plugging and unplugging
• Indoor versus outdoor; outdoor locations need NEMA 4 or NEMA 4X rated equipment rather than a standard indoor unit

Decisions to Make Before Installation Day

Hardwired or plug-in?

Plug-in installations use a NEMA 14-50 or 6-50 outlet, letting you unplug the charger and take it with you if you move, or swap units without another service call. Hardwired connections are permanent but occasionally allow higher continuous amperage under local code, and some manufacturer warranties require hardwiring for the top charging speed. Most homeowners choose plug-in with a NEMA 14-50 unless their jurisdiction or charger model requires hardwired.

Amperage: 40A vs 48A vs 60A circuit?

The 80% continuous-load rule means a 50A circuit delivers 40A continuous, and a 60A circuit delivers 48A continuous. Most Level 2 home chargers draw 32A, 40A, or 48A, so you'll want a 50A circuit at minimum for a 40A charger, and a 60A circuit for a 48A unit. A 60A circuit also gives headroom if you upgrade to a faster charger or add a second EV later, since re-running wire later costs more than sizing correctly the first time.

Do you need a permit?

Check your city or county building department website, or ask your electrician directly. Most jurisdictions require an electrical permit for any new 240V circuit, including EV chargers. Your electrician usually handles the permit application and schedules the inspection, but you should know the requirement and the typical cost ($0 to $200 depending on your municipality) upfront so it isn't a surprise line item on the final invoice.

Day-Of Installation Checklist

• Clear the area around your electrical panel; the electrician needs full, unobstructed access to the panel door and the floor space in front of it
• Clear the mounting area; remove shelving, bikes, or storage bins in the path between panel and charger
• Have your charger unboxed and ready, unless the electrician is supplying and installing the unit themselves
• Confirm WiFi reaches the garage or mounting location if you're installing an app-connected smart charger
• Make sure someone is home who can authorize a brief shutoff of main power if the electrician needs to work the panel safely
• Have your car available afterward to test the charger and confirm it reaches full rated amperage on your vehicle's display

Questions to Prepare for Your Electrician

1. Can my panel handle a 50A or 60A circuit without an upgrade, based on my existing appliance load?
2. What's the total cost including the permit fee and the inspection?
3. Is the estimate fixed or hourly, and what happens if the job runs longer than expected?
4. Do you handle the permit application and schedule the inspection yourself?
5. What warranty do you offer on the installation labor, separate from the charger manufacturer's warranty?
6. Will the circuit be sized for my current charger only, or with headroom for a future upgrade?

What the Electrician Brings vs What You Provide

A licensed electrician typically arrives with wire, conduit, the breaker itself, junction boxes, and standard fasteners already on the truck; these are usually included in the quoted price. What you're expected to provide is the charger unit (unless you asked them to source and mark it up), clear access to the work area, and, in most cases, the permit fee paid directly to the municipality even though the electrician files the paperwork. If you're supplying your own NEMA 14-50 receptacle like the Bryant unit above rather than letting the electrician choose one, mention that on the phone before they arrive; some electricians prefer to use their own stock so they can warranty the full installation as a single unit.

HOA and Landlord Approval

If you live under a homeowners association, check the CC&Rs before the electrician's visit; many HOAs classify exterior conduit runs, new meter equipment, or garage modifications as requiring architectural approval, and some states now have "solar and EV rights" statutes that limit how much an HOA can restrict a charger installation. Renters should get written landlord approval for any permanent electrical work, since removing a hardwired charger at move-out is far more disruptive than unplugging a NEMA 14-50 unit. Both approvals typically take longer than the installation itself, so start that conversation a week or two ahead rather than the day you schedule the electrician.

Being prepared turns a potentially stressful, multi-visit installation into a smooth single appointment.
