Home / Charging / ChargePoint Charger Installation
ChargePoint Charger Installation
Load management exists because not every house needs a bigger service to charge a car. An EV charger is a continuous load, which means it is sized differently from an outlet you plug a tool into.
ChargePoint Charger Installation in O’Fallon and across St. Charles, St. Louis, Lincoln and Warren counties.

What this work actually involves
The circuit is sized for continuous duty and run on its own breaker, with the disconnect where the code and the inspector expect it.
Clint measures before he quotes. The reading comes first, then what it means, then the one repair that solves it. If the honest answer is smaller than what you called about, that is the answer you get, even when the bigger job pays better.
Work that needs a permit gets one, and work that needs an inspection is left ready for it. One person does the diagnosis and the repair, so nothing is lost between a salesman and a technician.
When people call about this
- A panel with no spare double-pole space
- A garage with no dedicated circuit
- Wanting a second charger
- A charger moved from an old house
Why people choose Clint for it
A one-person shop cannot be in two places at once, so you get a real date instead of a window. What you also get is the same person every time.

Where this is done
Thirty towns across five jurisdictions, worked out of O’Fallon. The housing stock and the inspection process both change as you move across them.

Where the charger should actually go
Cable length and mounting height decide whether you still like the install a year later. The cable has to reach the car’s port on the side it is parked, with slack to hang without dragging.
Future second cars matter too. Running conduit for a second charger while the wall is open costs very little; adding it later means opening the wall again.
What happens when you change cars
Connectors and charging rates change; the circuit does not. A properly sized 240 volt circuit with the right receptacle outlives several cars, and most of what changes is the unit on the wall.
That argues for a receptacle rather than a hardwired unit where the code and the charger allow it, because swapping a plug-in charger is a ten minute job and swapping a hardwired one is a service call.
ChargePoint on a residential service
The residential ChargePoint units are adjustable like most Level 2 chargers, so the circuit is built around the amperage you set rather than the maximum on the box. That is the lever that keeps many houses off a service upgrade.
WiFi provisioning and the app pairing happen on site, and the unit is test-charged on your car before it is left.
Why the diagnosis comes before the quote
A symptom has several possible causes with very different prices, and the only thing that separates them is a measurement. Quoting the expensive one covers the risk; quoting the cheap one and finding the expensive one mid-job is worse.
So the reading happens first, you are told what it says, and then the work is scoped to it. Where the honest answer is the small repair, that is the answer you get, even when the larger job pays better.
Permits, inspections and why they vary here
Requirements genuinely differ across this metro. O’Fallon, St. Charles, St. Peters, the St. Louis County municipalities and St. Louis City each run their own process, and what one treats as a minor repair another permits and inspects.
Work that needs a permit gets one, and work that needs an inspection is left ready for it with the panel labeled and the junctions accessible. That matters most before a closing, when an inspector’s written item becomes someone’s negotiating position.
“Clint came out installed me a large 200 amp panel put some new dedicated lines in my basement and garage he did great clean work all inspections passed he was thorough and knowledgeable. I will have him back out again.”

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

ChargePoint Charger Installation across the metro
Where the house is changes what the work involves. Clint works out of O’Fallon across five jurisdictions, and the same service means different work in each.
St. Louis City
St. Louis City is century brick with shared walls and basement panels that have been added to five times. Code corrections and occupancy inspections are the common call.
Lincoln County
Outages last longer this far from town, which changes the backup conversation from comfort to the pump.
Warren County
Which of those you have changes the entire conversation, so the first visit establishes what is actually there rather than assuming from the address.

Questions worth asking first.
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.
Level 1 or Level 2?
Level 1 plugs into a standard outlet and adds a few miles an hour, which suits short commutes. Level 2 needs its own circuit and fills a car overnight. The honest answer depends on your daily miles.
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.
Are you licensed and insured?
