What the houses here need
Marthasville sits in Warren County, which means a mix of newer builds and older farm properties, with generator work more common than in town.
That shapes the work. Clint measures before he quotes, tells you what the reading says, and fixes the thing that is actually wrong. If the service is fine and one circuit is overloaded, you hear that.
Permits are pulled where Marthasville and Warren County require them, and the work is left ready for inspection. Requirements genuinely differ between municipalities here, which is worth knowing before a closing.
Older houses and newer appliances
The recurring combination around Marthasville is a house wired for the loads of its decade now running a heat pump, an induction range, a finished basement and a car charger. Nothing in the walls failed; the demand changed.
That is a measurement problem rather than a guess. The load gets calculated against the service, and the answer is frequently load management or one new circuit rather than the service upgrade people brace for.
Storms, outages and backup power
Summer storms through this part of Missouri take lines down, and the backup power conversation in Marthasville is usually about a short list rather than the whole house: the furnace blower, the refrigerator, a sump or well pump, some lighting.
Written down and added up honestly, that list is smaller and cheaper than running everything. Whichever size is chosen, the transfer has to make back-feeding the utility physically impossible, which means a transfer switch or a listed interlock.
Getting a straight answer about urgency
Some things in Marthasville move to the front of the day and some genuinely wait. Heat or a burning smell at a panel or an outlet, visible arcing, water in electrical equipment, or losing power to half the house: those are now.
A breaker that has tripped once, a dead outlet, a fixture that flickers: those can be scheduled. You get told which category you are in rather than being sold urgency.
What a service call in {city} actually costs you in time
The honest variable is not the hourly rate, it is whether the job needs a utility disconnect or a permit office. A device, a breaker or a circuit addition is usually a single visit. A service change means coordinating Ameren for the disconnect and a municipal inspection, which puts it on a scheduled day.
Knowing which one you have before anything is booked is most of the value of the first phone call, and it is why the symptom matters more than the guess at the cause.
Grounding, which most older {city} houses are short on
An equipment ground gives fault current a path back so a breaker can see it and trip. Two-prong outlets have none, and a three-prong outlet retrofitted onto two-wire cable has the appearance of one without the function, which is worse because it reads as safe.
That gets tested rather than assumed, because a ground that is not connected looks exactly like one that is. Where a ground is missing, the correction is either a real one or GFCI protection with the outlet labeled as the code allows, and you are told which applies.
Why one circuit keeps tripping and the rest never do
A breaker that trips repeatedly on one circuit in a Marthasville home is reporting something real, and there are only a few possibilities: more connected load than the circuit carries, a fault at a termination, a shared neutral, or a failing breaker. Those have very different prices.
Measuring the circuit’s draw under actual use separates the first from the rest in a few minutes, and dividing the circuit finds a fault without replacing anything on a hope.
Two-prong outlets and what they mean in {city}
An outlet with two slots has no equipment ground, which means a fault has no low-resistance path back and the breaker may never see it. Retrofitting a three-prong receptacle onto two-wire cable produces the appearance of a ground without the function, which is worse because it reads as safe to anyone checking.
Testing tells you which you have in seconds. Where a real ground cannot be run, GFCI protection with the receptacle labeled is what the code allows, and you are told which route applies to your circuit rather than sold the larger one.
“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.”

Clint covers the whole county out of O’Fallon. These sit close together and are not interchangeable: the same work is permitted differently in each.
Every service is listed on the services page, the rest of the area on Warren County, and finished work in the gallery. Ask for a visit when it suits.
Questions worth asking first.
Do you charge to tell me what is wrong?
You get the reading and what it means before any work is agreed. Where the honest answer is a small repair, that is the answer, even when the larger job pays better.
Will an inspector pass it?
That depends on grounding and terminations more than on the conductors. Those are the items that get corrected, documented and re-inspected so a file closes.
What size generator do I need?
It depends on what has to keep running. A well pump, a sump pump and a furnace need very different capacity from a whole house, and picking the loads deliberately keeps the cost sensible.
Who actually shows up?
Clint Ehman. Infinity Electric is owner-operated, so the person who answers the phone is the person who measures your panel and pulls the permit. There is no dispatcher and no commissioned salesman.
Are you licensed and insured?
