EV charger installation, done to code.
Level 2 home chargers, panel and service upgrades, and multi-port commercial and fleet charging across Chester, Montgomery, Delaware, Bucks and Lancaster County PA, plus New Castle County DE — sized off a real load calculation.
Your panel, not your charger
Almost every EV charger quote that goes wrong goes wrong the same way: someone priced the install without running a load calculation, then found out on install day that the service will not carry it.
A lot of housing here was built between 1950 and 1990 and still runs on 100-amp service. Add an electric range, an electric dryer, central air and a 48-amp charger, and the calculation does not clear. Your options at that point are a service upgrade, a smaller charger, or a load management device — and all three should be priced before you commit, not discovered afterward.
What a load calculation actually tells you
We add up the fixed loads already on your panel — heating and cooling, range, dryer, water heater, general lighting and receptacle load — apply the demand factors the code allows, and see what capacity is left. A charger counts as a continuous load, which means it is figured at 125 percent of its rating.
That last point catches people out. A 48-amp charger on a 100-amp service is not a 48 percent load. It occupies 60 amps of the calculation, before anything else in the house is counted.
Three ways it usually resolves
- Right-size the charger. Most people do not need 48 amps. A 32-amp charger adds roughly 25 miles of range an hour, which fills any normal commute overnight. Dropping from 48 to 32 often removes the need for an upgrade entirely.
- Load management. A device that sheds the charger while the dryer and range are running lets a charger sit on a service that would not otherwise take it. Cheaper than an upgrade and invisible day to day.
- Upgrade the service when it is genuinely needed. Sometimes 100 amps is not enough, and we will say so rather than squeezing a charger onto a panel that should not have one.
Home charging
A Level 2 home charger turns overnight parking into a full battery. The install itself is usually straightforward; what determines cost is the distance from your panel to the parking spot and whether your existing service can carry the load.
We start with a load calculation — not a guess. Many older homes in Chester County and the Wilmington suburbs are on 100-amp service, which often can't support a 48-amp charger alongside an electric range, dryer, and air conditioning without a service upgrade or a load management device.
What a residential install includes
- Load calculation and panel capacity assessment
- Dedicated circuit, conduit run, and breaker
- Hardwired or NEMA 14-50 receptacle installation
- Panel or service upgrade where the calculation requires it
- Testing, commissioning, and app pairing
We install Tesla Wall Connectors and all major third-party chargers — ChargePoint, Wallbox, Emporia, Grizzl-E, and Enphase among them. If you haven't bought one yet, we'll tell you which makes sense for your service and vehicle before you spend the money.
Hardwired or plug-in
A NEMA 14-50 receptacle is cheaper and lets you unplug the unit if you move. Hardwiring supports higher amperage, is required outdoors in some jurisdictions, and removes the receptacle as a failure point — which matters, because a cheap 14-50 receptacle carrying 40 amps continuously for years is one of the more common causes of a charging circuit overheating.
If you go plug-in, the receptacle should be industrial grade. It is a small part of the job cost and it is the part most likely to fail.
Where the charger goes
Distance from the panel drives more of the price than anything except a service upgrade. A charger on the garage wall directly behind the panel is a short run in conduit. A charger at the far end of a detached garage means trenching, and trenching in this part of Pennsylvania frequently means rock.
Worth thinking about before we quote: which side your charge port sits on, whether you back in or pull forward, and whether a second EV is coming. Running conduit for two while the wall is open costs far less than doing it twice.
Multi-port and workplace charging
Charging as building infrastructure — sized for what the property will need in five years, not just today.

Frequently asked questions
For almost everyone, 32 amps is enough. It adds roughly 25 miles of range an hour, so a 40-mile commute replenishes in under two hours and any overnight charge fills the battery. 48 amps matters if you drive very high daily mileage or run two vehicles off one charger — and it frequently forces a service upgrade, because a continuous load is figured at 125 percent, so 48 amps occupies 60 amps of your calculation.
It is a device that watches your service and reduces or pauses the charger when the rest of the house is drawing heavily. In practice you never notice, because the moments it intervenes are when you are cooking and running the dryer, not at 2am when the car is actually charging. It often lets a charger sit on a 100-amp service that would otherwise need upgrading, at a fraction of the cost.
Plug-in is cheaper and lets you take the unit with you. Hardwiring supports higher amperage, is required outdoors in some places, and removes the receptacle as a failure point — a cheap 14-50 carrying 40 amps continuously for years is one of the more common causes of a charging circuit overheating. If you do go plug-in, insist on an industrial-grade receptacle. It is a small part of the cost and the part most likely to fail.
It depends on three things: the distance from your panel to the charger, whether the run goes through open framing or a finished wall, and whether the load calculation says your service needs upgrading. Those swing the number enormously, which is why we run the calculation and walk the route before quoting rather than guessing. You get a fixed price in writing after that.
Often, but not always. Homes on 100-amp service with electric heat, an electric range, or an electric dryer frequently need either a service upgrade or a load management device. We run a load calculation before quoting so you get a real answer rather than a surprise on install day.
Yes. We install Tesla Wall Connectors along with ChargePoint, Wallbox, Emporia, Grizzl-E, Enphase, and other major brands. If you supply the unit, we install it; if you'd rather we source it, we can.
Usually something, but programs change constantly and vary by utility and state. Rather than repeat figures that go stale, we point you at the two databases that are actually maintained:
afdc.energy.gov/laws — the Department of Energy’s incentive database, searchable by state. dsireusa.org — the same idea, run out of NC State, and broader than EVs.
The application itself normally happens with your utility, so once you know what exists, go to them directly — PECO and PPL cover most of our Pennsylvania footprint. Federal credits for home charging equipment are tied to census-tract eligibility, so confirm current status with your tax preparer before counting on it.
