Short answer
Most home EV charging uses a Level 2 charger on a dedicated 240-volt circuit, mounted in the garage near where the car parks. Before installing, we run a load calculation to see whether your panel and service can carry the charger along with everything else. If they can't, the answer may be a panel upgrade or a charger set to a lower current.
One recent job: an EV charger installed in a customer's garage, on the same project as a full electrical install in their horse barn. Most EV charger jobs are simpler than that, but every one starts with the same question: can your service carry it?
Level 1 vs. Level 2
Level 1: a standard outlet
Most EVs come with a cord that plugs into a regular 120-volt outlet. It's slow, adding a few miles of range per hour, but for some drivers it's enough. If you go this route, the outlet should be on a circuit that isn't shared with a freezer, a shop compressor or other big loads, and it should be in good condition. An EV draws steady current for hours, and a worn outlet can overheat.
Level 2: a 240-volt circuit
A Level 2 charger runs on 240 volts, like a dryer or range, and charges several times faster. That's what most EV owners end up with. It needs a dedicated circuit sized for the charger, and the wire, breaker and charger setting all have to match.
What's involved
Load calculation and panel capacity
An EV charger is one of the biggest loads in a house, and it can run for hours at a time. A load calculation looks at your service size and everything else on it, such as the range, dryer, water heater, heat pump or electric heat, and AC, to see how much room is left. If there's not enough, the options are a panel or service upgrade, or setting the charger to a lower current that the service can support.
Panel space
A Level 2 circuit needs a two-pole breaker, which takes two spaces. A full panel may need rearranging, a subpanel, or replacement. A fuse box can't take an EV circuit, so that usually means an upgrade first.
Placement in the garage
The charger goes where the cord reaches the car's charge port comfortably, without stretching across a walkway or getting run over. We also look at the path the wire takes from the panel, since a shorter run through an unfinished wall or along the garage is usually simpler and less expensive than one through finished rooms.
Hardwired or plug-in
A hardwired charger connects directly to the circuit. A plug-in model uses a heavy-duty 240-volt outlet. Either can be the right choice. We go by the charger's installation instructions, the circuit size and where it's mounted.
How the job goes
- Questions first. What you drive, how far you drive, which charger you have or are considering, and where you park.
- Look at the panel and service. Size, available spaces, condition, and a load calculation.
- Plan and quote. Circuit size, wire route, charger location, and whether any panel work is needed.
- Install. Circuit, breaker, outlet or hardwired connection, and the charger mounted, with a permit and inspection where your city or county requires it.
- Test. We check the circuit and confirm the charger communicates with the car and charges.
What it costs
This work is priced per job, because the house, the distances and what's already in the panel are different every time. Ask for a quote that lists the materials and everything included. For what drives electrical prices in general, see what electrical work costs.
The biggest factors are the distance from the panel to the charger, whether the panel has room and capacity, and whether a detached garage needs a new feeder. A written quote should say whether the charger itself is included.
Local detail: older services and detached garages
A lot of homes around Huntington were built long before anyone planned for a car charger. According to the U.S. Census (American Community Survey, 2020–2024 five-year estimates), the median home in Huntington County was built in 1966, and many older homes still have 100 amp services. Detached garages are common, and the wire feeding them was often sized for a light and an outlet. Those are the two things we look at most carefully before an EV install. If your garage needs a bigger feeder or a subpanel, see barns, garages and outbuildings.

Common questions
Do I need a Level 2 charger, or is a regular outlet enough?
Level 1 charging from a standard 120-volt outlet adds only a few miles of range per hour. That can be enough if you drive a short daily commute and park overnight. If you drive more, have a larger battery, or want to recover a full charge overnight, a Level 2 charger on a 240-volt circuit is usually worth it.
Will I need a panel upgrade for an EV charger?
Sometimes. A Level 2 charger is a large, long-running load. A load calculation shows whether your existing service can carry it along with everything else in the house. Many 200 amp homes can. Many 100 amp homes, especially with electric heat, a range and a dryer, cannot without an upgrade or a lower charging setting.
Should the charger be hardwired or plugged into an outlet?
Both can work. A hardwired charger has no plug to wear out and is often the choice for higher-power units and outdoor locations. A plug-in charger on a 240-volt outlet is easy to swap or take with you. The charger manufacturer's instructions and your circuit size help decide.
Can you install a charger in a detached garage?
Often, yes. It depends on the size of the feeder already running to the garage. If it is too small, a new feeder and possibly a subpanel in the garage may be needed.
