EV charger installation, done at home.

Tired of hunting for a public charger that's free and working? Plug in at home instead. We mount a Level 2 charger on your garage wall, and you wake up to a full battery. One thing first: we check whether your panel can carry it. About half of older NoVA homes need a panel upgrade, and we tell you that on day one, not three weeks in.

Panel capacity comes first

EV charger circuits need 40A or 50A continuous-duty dedicated capacity. About half of NoVA homes built before 2000 need a 200-amp service upgrade before an EV charger can land safely. We assess your panel during the consultation and tell you up front whether yours is one.

Tesla, Ford, GM, Rivian - all supported

Tesla Wall Connector for Tesla vehicles. ChargePoint, Wallbox, JuiceBox, or NEMA 14-50 outlets for everything else. We install what your vehicle needs - and we don't push the brand we make the highest margin on.

Permits pulled, GFCI verified

Every EV install in NoVA requires a permit pulled by a licensed electrician. We pull it. We verify GFCI on the supply if applicable (NEMA 14-50). First-time inspection pass, every time.

Why an EV circuit is not just another outlet

EV charging carries different code requirements than typical residential outlets: NEC Article 625 covers continuous-duty derating, dedicated-circuit requirements, GFCI rules on plug-in installations, and disconnect placement. Combined with NEC 220 load calculations on the panel side, EV installs are one of the few residential electrical projects that genuinely require code expertise.

The panel-upgrade conversation: Most EV charger installers will quote the charger circuit without checking whether your panel has the headroom to support it. We don't. During the consultation, we run a NEC 220 load calculation on your existing panel - adding up the connected load (HVAC, range, water heater, dryer) and comparing against your panel's rated capacity. If you're at 80% or above with the EV charger added, we tell you. About half of NoVA homes built before 2000 need a 200-amp service upgrade before an EV charger can land. We'd rather tell you that on consultation day than have you discover it three weeks into the install.

Continuous-duty derating and dedicated circuits

EV chargers run at maximum amperage continuously for hours during a charging session. NEC 625 requires that continuous loads be sized at 125% of the load - meaning a 40A charger needs a 50A circuit, and a 48A Tesla Wall Connector needs a 60A circuit. The dedicated-circuit rule applies on every install - no sharing the EV charger circuit with other loads.

NEC 220 · Load Calculations

Panel capacity assessment before quote

We run a load calculation per NEC 220 before quoting any EV install. Total connected load plus EV charger demand must not exceed 80% of panel rating for a sustained safety margin. If your panel is a 100-amp panel and your home already runs HVAC plus electric appliances at typical NoVA loads, you almost certainly need a 200-amp panel upgrade before the EV install. We quote both as one project if so.

Tesla, Wallbox, ChargePoint, JuiceBox - we install all

The Tesla Wall Connector (OEM for Tesla vehicles) is our most-requested install. Wallbox Pulsar Plus, ChargePoint Home Flex, and JuiceBox are common for non-Tesla EVs. Each has different installation specs - Tesla is hardwired only, ChargePoint and Wallbox offer hardwired or NEMA 14-50 plug-in, JuiceBox is plug-in. We tell you which is right for your vehicle and your panel - no brand preference.

NEC 110.14 / 210.8 · Hardwired vs. plug-in

When plug-in is enough, when hardwiring is required

NEMA 14-50 plug-in installs are simpler and cheaper but max out at 40A continuous (vs. 48A hardwired for the Tesla Wall Connector). For Tesla owners who want maximum home-charging speed, hardwired is the right call. For renters, garages without permanent install plans, or smaller EVs that don't benefit from 48A charging, NEMA 14-50 is fine. We walk through the tradeoffs during consultation.

How we work

What getting your charger installed actually looks like

Most installs take two visits. First we come look at your panel, the spot you want the charger, and the car you drive. Then we come back and do the work. Already picked your charger and your panel has room? We can often do it all in one day. Either way, the same crew handles both visits - no handoff to a stranger.

01

Free consultation (visit #1)

We come look at your panel, the install location, your vehicle, and your charger if you've already bought one. Load calculation per NEC 220 done on-site.

02

Written proposal

Itemized. Includes the charger circuit, the panel upgrade if needed, and the permit fee. If your panel needs upgrading, we quote both as one project so you have the full cost up front.

03

Permit + install (visit #2)

We pull every permit in your jurisdiction. Most installs complete in 4-6 hours on install day, longer if a panel upgrade is bundled.

04

Inspection + walkthrough

County inspection scheduled. We walk you through the charger, the breaker, the GFCI test if applicable, and the labeled panel directory.

FAQ

What homeowners ask us before the truck shows up

The questions we hear most, answered plainly. If yours isn't here, just call and ask.

Do I need a panel upgrade before installing an EV charger?

About half of NoVA homes built before 2000 need a 200-amp panel upgrade before an EV charger can land safely. The exact answer depends on your panel's rating (100A vs. 150A vs. 200A) and your home's connected load (HVAC, range, water heater, dryer). We run an NEC 220 load calculation during the consultation and tell you up front.

If your panel is 100A or 150A with central HVAC plus an electric range and electric water heater, you almost certainly need a 200A upgrade. If your panel is already 200A with mostly gas appliances, you almost certainly don't. In-between cases (a 200A panel but a lot of electric load) need the calculation done. We quote the panel upgrade and EV install as a single project when needed - no surprise pricing.

How long does a typical EV charger installation take?

For a straightforward install on a panel with headroom: 4-6 hours of on-site work, completed in one day. If a panel upgrade is bundled, the project typically runs 1-2 days. Consultation is a separate visit, typically 30-45 minutes.

The variable that most affects timeline is panel-side work - running the new circuit from panel to charger location, drilling through walls if needed, and conduit routing. Long conduit runs (garage to a detached structure, a second-floor charger location, and the like) add time. We give you a written schedule in the proposal before any work starts.

What's the difference between a Tesla Wall Connector and a NEMA 14-50 outlet for charging?

A Tesla Wall Connector is a hardwired Level 2 charger that delivers up to 48 amps for fastest home charging (about 44 miles of range per hour for a Tesla Model 3 or Y). A NEMA 14-50 is a heavy-duty 240V outlet you plug a portable charger into - max 40A continuous, about 30 miles per hour. Hardwired is faster and safer; NEMA 14-50 is cheaper and more flexible.

For most Tesla owners we recommend the hardwired Wall Connector. The 8-amp speed bump matters over time, the wall-mounted unit is cleaner, and you eliminate the failure point of a plug-and-receptacle interface. For renters, garages where you don't want to commit to a permanent install, or non-Tesla EVs that ship with a NEMA 14-50 mobile cord (Ford F-150 Lightning, Rivian, and others), NEMA 14-50 is the right call. We talk through both options during the consultation.

Are you a Tesla Certified Installer?

We are not formally certified by Tesla, but we install Tesla Wall Connectors regularly and follow Tesla's published installation guide on every job.

The Tesla Certified Installer program covers installation training, troubleshooting access, and warranty alignment. Tesla's installation guide is public, and any licensed Master Electrician can follow it. For homeowners, the practical question is whether the installer knows the wiring spec for the Gen 3 Wall Connector. We do - and our Master Electrician (#2705178102) signs off on every job.

Can I install an EV charger myself, or do I need an electrician?

In Virginia, EV charger circuits (240V dedicated, 40A and up) require a licensed electrician and an electrical permit. It's not legal for a homeowner to install an EV charger circuit on their own home without the permit being pulled by a licensed electrician. The charger device itself (hardwiring or plugging in) can be done by you if the circuit is already installed and permitted.

The boundary is this: circuit-level work (a new 240V circuit, a panel breaker addition, conduit, GFCI on a NEMA 14-50) requires a licensed electrician plus a permit. Mounting the Wall Connector on the wall and connecting it to an existing dedicated 60A circuit can be done by a handy homeowner if the circuit is already in place. Most homeowners hire the full install because it's straightforward to bundle and the permit covers the work.
