EV Charger Installation for Apartments
Load management exists because not every house needs a bigger service to charge a car. The charger is the easy part. Whether the service can carry it alongside the air conditioning and the dryer is the real question.

What this work actually involves
The charger is mounted where the cable actually reaches the car, which sounds obvious and is the most common complaint about other people’s work.
First the reading, then the explanation, then the repair scoped to what was actually found. If that turns out smaller than the job you called about, that is what you are charged for.
Work needing a permit gets one and work needing an inspection is left ready for it. There is no handoff between whoever quotes and whoever fixes, because they are the same person.
When people call about this
- A charger moved from an old house
- A new EV on order
- A charger that trips mid-session
- A panel with no spare double-pole space

Continuous load, and why it changes the maths
Code treats EV charging as a continuous load, which means the circuit is sized at 125 percent of the charger’s rating. A 40 amp charger wants a 50 amp circuit. That single rule explains most of the difference between an EV install and an ordinary outlet.
It also explains why a charger that worked at an old house trips at a new one. The charger did not change; the circuit behind it did.
Load management instead of new service
Load management lets the charger share capacity with another large appliance rather than adding to it. The charger backs off while the range or the dryer runs, then resumes. For a car sitting in a garage for ten hours, that pause costs nothing.
It is code-compliant, it is far cheaper than a service upgrade, and it is the answer a great many houses around here should be getting instead of a quote for new service.
The three answers before a service upgrade
Charging load is the most common reason a house suddenly looks short on capacity, and a service upgrade is only one of three honest answers. The other two are a smaller charger that still fills the car overnight, and load management that shares capacity with the range or dryer.
The load calculation decides which, and you see it. Both alternatives are code-compliant and both are cheaper than new service.
Charging speed versus charging enough
The question is not how fast a charger can go, it is whether it finishes overnight. For most households a charger running at half its maximum still fills the car by morning, and that halves what the circuit has to carry.
Working out your real daily mileage before choosing a unit is the cheapest part of the whole project and the part most often skipped.
What gets left behind when the work is done
A labeled panel, accessible junctions, the old parts if you want to see them, and a straight account of anything found along the way that was not part of the call.
Where something else was found, you get told what it is and whether it needs doing now, later or not at all. That third answer is a real answer and it gets used.
“Infinity came out for same day service after an electric line had been cut in my yard. He was able to locate and correct it very quickly, eliminating any risk of injury or additional power outage.”

How the visit goes
- The call
Which car, which charger, and where it parks. Those three answers decide most of the install before anyone visits.
- The measurement
A load calculation against the existing service, plus the run from the panel to the parking spot and what it passes through.
- The finding
Either the service carries it, or load management lets it share, or a service upgrade is genuinely needed. You hear which, with the number behind it.
- The work
Dedicated circuit sized for continuous duty, disconnect where the code and the inspector expect it, charger mounted so the cable reaches with slack, and a test charge before anyone leaves.
What the job includes
- Load calculation to confirm the service can carry the charger
- A dedicated circuit sized for continuous duty, on its own breaker
- Charger mounted where the cable reaches the car with slack to spare
- Disconnect where code and the inspector expect it
- Permit and inspection where required
- Conduit for a second charger while the wall is open, if you want it
What it does not
- Supplying the charger itself, unless you ask
- Utility rebate paperwork, though we will tell you what exists
- Charging network accounts and apps
Anything that is not an electrical problem gets identified as such and handed on. Finished work is in the gallery. To book, pick a day.

EV Charger Installation for Apartments across the metro
Five jurisdictions, five different sets of conditions. The housing stock changes as you cross this metro, and so does what the job involves.
St. Charles County
St. Charles County is mostly 1990s and 2000s subdivisions. The wiring is modern and the services were sized before anyone owned an electric car or finished a basement, so capacity is the usual constraint rather than condition.
St. Louis County
Houses with real history in the walls, and a permit process that changes from one municipality to the next.
St. Louis City
Much of this stock is two and four family, which means shared services and panels that are rarely labeled accurately.
Every municipality covered is listed on the service areas page.
Questions worth asking first.
Do I need a 60 amp circuit for a 48 amp charger?
Yes. Charging is a continuous load, so the circuit is sized at 125 percent of the charger’s draw. That is also why dialing the charger back is often what keeps a house off a service upgrade.
Can two cars share one circuit?
With load-managed chargers, yes, and for most two-car households overnight charging still finishes both. It is considerably cheaper than new service.
Can my panel handle a charger?
Often yes. The load calculation checks what the house already runs against the service rating. Where it is tight, load management lets the charger share capacity instead of forcing an upgrade.
Where do you work?
Out of O’Fallon across St. Charles County, St. Louis County, St. Louis City, and Lincoln and Warren counties, roughly a fifty mile radius.
Do you pull permits?
Where the municipality requires one, yes, and the work is left ready for inspection with the panel labeled and junctions accessible. Requirements genuinely differ across this metro, which is why it is established per address rather than assumed.
