Fuse-to-Breaker Conversion
The difference between a panel that is full and a panel that is undersized is not the same conversation. A panel is the one part of a house every other circuit depends on, so it is the part worth measuring before anyone touches it.
Fuse-to-Breaker Conversion in O’Fallon and across St. Charles, St. Louis, Lincoln and Warren counties.
Clint Ehman does the work himself. Seventeen years in the trade, Infinity Electric since June 2022.

What this work actually involves
Permits are pulled where the municipality requires them, and the work is left ready for inspection rather than tidied up afterward.
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
- Lights that dim when a large appliance starts
- Breakers that trip under normal load
- A panel brand an inspector flags on sight
- Scorch marks, heat or a smell at the cover
Why people choose Clint for it
The diagnosis and the repair are the same person’s work, which is why the explanation you get is first-hand rather than relayed.
Five point zero from 94 Google reviews, A+ with the BBB since December 2022, and seventeen years in the trade behind it.
Where this is done
Out of O’Fallon across five jurisdictions: St. Charles County, St. Louis County, St. Louis City, and Lincoln and Warren counties. About fifty miles in any direction.

How the load actually gets calculated
A load calculation is arithmetic, not a guess. Square footage sets a baseline, then the fixed appliances get added at their nameplate ratings: the range, the dryer, the water heater if it is electric, the air conditioning, and anything else with its own circuit. The largest of the heating or cooling loads counts, not both.
What comes out is a number in amps. Compare it to the service rating and you know whether the house is near its limit or nowhere close. That is the whole decision, and it is why the measurement happens before anyone quotes a panel.
What a panel directory is worth later
An accurate circuit directory is the cheapest thing in a panel and the one most often missing. Without it, every future visit starts with twenty minutes of somebody switching breakers off and shouting down a hallway, and you pay for those twenty minutes.
Every circuit gets identified and written on the directory as part of the work. It is also one of the first things a municipal inspector looks at, because an unlabeled panel is a hazard to whoever opens it next.

Breakers, and the ones with no replacement
A breaker that trips is usually doing its job. A breaker that is warm, that will not reset, or that sits in a panel with heat marks on the bus is a different conversation, and the bus is the part that cannot be seen with the cover on.
Some panel lines, Federal Pacific Stab-Lok and Zinsco among them, have no current listed replacement breaker, so the correct answer there is the panel rather than the part. If that is what is on the wall, you are told.
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.
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.
“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
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
If the fix belongs to another trade, you get the name of one rather than a price from this one. Finished work is in the gallery. To book, pick a day.
Related panels & service work
Fuse-to-Breaker Conversion across the metro
Five jurisdictions, five different sets of conditions. Clint works out of O’Fallon across five jurisdictions, and the same service means different work in each.
Warren County
Newer builds beside older farm properties, with outbuildings and well pumps that town panels never see.
St. Charles County
Modern wiring, undersized services. That combination defines most of the work in this county, and it makes the load calculation the deciding document rather than a panel inspection.
St. Louis County
Houses with real history in the walls, and a permit process that changes from one municipality to the next.
County by county coverage is on the service areas page.
Questions worth asking first.
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.
Do I need a bigger service, or just more space in the panel?
Those are different problems. A full panel with spare capacity takes a sub-panel or tandem breakers. A panel that is out of capacity takes a service upgrade, and the load calculation tells us which one you have before anything is ordered.
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.
