Electrical Service Entrance Repair
Bus bars and terminations tell you more about a panel’s future than its age does. Most panel calls start as something smaller: a breaker that will not reset, a burning smell, an inspector’s note on a sale.
Electrical Service Entrance Repair in O’Fallon and across St. Charles, St. Louis, Lincoln and Warren counties.
Clint Ehman, seventeen years in the trade, running Infinity Electric out of O’Fallon since 2022.
5.0 from 94 Google reviews · BBB A+ since 2022
What this work actually involves
The load gets calculated against what the house actually runs, not against a rule of thumb. If the existing service carries it, you hear that.
A number follows a measurement here, never a guess. You get told what the reading was and what it means before any work is agreed, including on the days when the answer is one loose connection.
Permitted and inspected where the address requires it, labeled at the panel, and done by the person who diagnosed it rather than handed down a chain.
When people call about this
- Scorch marks, heat or a smell at the cover
- No room left for a new circuit
- Fuses instead of breakers
- Lights that dim when a large appliance starts
Why people choose Clint for it
What the reviews keep mentioning is being told what the problem actually was. That is what an owner-operated shop can do and a dispatch model structurally cannot.

Where this is done
O’Fallon first, then the rest of St. Charles County, St. Louis County and the City, and out to Lincoln and Warren. If you are just past that, the call is still worth making.

Sub-panel or service upgrade
A sub-panel adds spaces. It does not add capacity. If the calculation says the service is fine and the panel is simply full, a sub-panel is the cheaper and entirely proper answer.
If the calculation says the service is undersized, a sub-panel just moves the problem. That is a service upgrade: new panel, new conductors, usually a new meter base, and coordination with the utility.
Why the bus matters more than the breakers
Breakers are replaceable parts. The bus bar they clip onto is not: it is the panel. Heat damage there shows as discolouration, pitting, or a breaker that will not sit tight, and none of those improve on their own.
That is why a panel assessment means taking the cover off rather than reading the label on the door. A panel with a sound bus and a tired breaker is a cheap repair. A panel with a damaged bus is a replacement, and you are told which you have with the reason attached.
What fails at the service entrance
The entrance conductors, the weatherhead and the mast take wind, ice and sun for decades. The failures are mechanical: a mast pulled out of plumb by a tree limb, a weatherhead with its insulation cracked, water tracking down into the meter can.
It gets inspected with the cover off and the utility coordinated for the disconnect. Water intrusion here is worth fixing before it reaches the panel bus, which is a much larger repair.
Labeling, torque and the parts nobody sees
The parts of a panel job that decide whether it lasts are invisible once the cover goes back on: conductors torqued to specification, neutrals and grounds separated correctly downstream of the main, and a directory that names real circuits.
None of that shows in a photograph and all of it shows in ten years. It is also what an inspector reads first.
What the price actually depends on
Three things move the number on almost every job: how far the run has to travel and what it passes through, whether the existing panel has space and the service has capacity, and whether the municipality wants a permit and an inspection. None of those is visible from the phone call, which is why the measurement comes before the quote.
What does not move it is urgency theatre. There is no inflated figure waiting to be discounted, and no bundle built so the thing you called about cannot be bought on its own.
“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
You describe what the house is doing and what prompted it: a tripping breaker, an inspector’s note, a planned addition. That shapes what gets measured first.
- The measurement
Load across the service under real conditions, voltage at the main, the condition of every lug and the bus. On an older panel, the breaker brand gets identified, because some have no listed replacement still made.
- The finding
You get the number and what it means. If the service carries what the house asks of it, you hear that, and the conversation becomes a sub-panel or a single circuit instead of a service upgrade.
- The work
Permit where required, utility coordinated for the disconnect, new equipment installed, every circuit identified and labeled, and the site left ready for the inspector.
What the job includes
- A load calculation against what the house actually runs, given to you as a number
- Permit application where the municipality requires one
- New panel, breakers and a legible circuit directory
- Utility coordination for the disconnect and reconnect
- Grounding and bonding brought to current requirements
- The site left ready for inspection, and the inspection attended
What it does not
- Drywall repair beyond the panel opening
- Appliance repair, which is a different trade
- Work on the utility side of the meter, which is the utility’s own
Anything outside electrical, you will be told who to call rather than sold it. See the work itself, or send the details.

Electrical Service Entrance Repair across the metro
The same job is not the same job in every part of this metro. Five jurisdictions, five different sets of conditions, all worked out of O’Fallon.
Lincoln County
Distance is the design factor out here. A run to a shop or a well house is often hundreds of feet, which makes voltage drop a real calculation rather than a textbook one.
Warren County
It is the far end of a roughly fifty mile radius, so visits get grouped rather than squeezed in. That affects the date, not the price.
St. Charles County
Twenty and thirty year old subdivisions where nothing has failed and the service is simply at its limit. That is the recurring call.
See which towns fall inside the radius on the service areas page.
Questions worth asking first.
Will the power be off all day?
A panel change means the service is off while the work happens, usually most of a working day. You will be told the window before the day starts, and the utility and inspection timing are arranged around it.
How do I know if my panel brand is a problem?
Federal Pacific Stab-Lok and Zinsco both have documented failure-to-trip histories and no current listed replacement breaker, so the panel gets replaced rather than repaired. The label on the door identifies it in seconds.
Do I need a permit for panel work?
In every municipality in this footprint, yes, plus an inspection and a scheduled utility disconnect. That is why a panel change is a planned day rather than a same-day call.
Are you licensed and insured?
Licensed, bonded and insured, with workers compensation coverage, and accredited A+ with the BBB since 2022.
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.
