Question Answers

I smell something burning from an outlet in O'Fallon. How fast can an electrician get here?

A burning smell is a serious fire hazard that requires immediate dispatch. From our starting point near O'Fallon City Hall, we can typically reach homes in the Renaissance area within 8-12 minutes using I-70 for rapid access. Please turn off the breaker for that circuit and unplug any devices immediately while you wait. Our priority is to diagnose the source, which is often a loose connection or failing receptacle, and make the area safe before any repairs begin.

Our lights in O'Fallon flicker during storms. Is this from Ameren Missouri, and could it damage my computer?

Flickering during storms is common here due to our high lightning surge risk on the Ameren Missouri grid. These micro-surges and voltage sags absolutely can damage sensitive electronics like computers, smart TVs, and network equipment. The issue often originates on the utility side, but a whole-house surge protector installed at your main panel is the first line of defense. This device shunts dangerous surges to ground before they enter your home's wiring.

How should I prepare my O'Fallon home's electrical system for summer brownouts or an ice storm?

For summer AC peaks, ensure your HVAC system has been serviced and its dedicated circuit is in good health to prevent overload. A licensed electrician can perform a load calculation to see if your 150A service is adequate. For winter ice storms that threaten power loss, consider a professionally installed generator interlock kit and standby generator. This provides backup power to essential circuits safely, without the risks of using a portable generator incorrectly.

We live in the rolling plains near City Hall. Could the soil here affect our home's electrical grounding?

Yes, the soil composition in O'Fallon's rolling suburban plains can impact grounding electrode resistance. Rocky or dry clay soil, common in our area, is less conductive than moist loam. This means your grounding system—the critical path for fault current and surges—may not perform optimally. During a panel inspection or upgrade, we test grounding electrode resistance. If it's too high, we can improve it by adding a second ground rod or using a chemical ground enhancement material.

We have a Federal Pacific panel and want to add an EV charger. Is our 1999-built O'Fallon house safe for this upgrade?

A Federal Pacific panel is a known safety hazard and must be replaced before any major upgrade. These panels have a high failure rate and are not compatible with modern safety devices like AFCI breakers. Even with a new 200A panel, supporting a Level 2 EV charger or a modern heat pump requires a dedicated load calculation. Your 150A service from 1999 is likely at capacity, so a full service upgrade is often the safest path forward for these high-demand additions.

I want to upgrade my electrical panel in O'Fallon. What permits are needed, and do you handle that?

Any panel replacement or service upgrade requires a permit from the O'Fallon Building Division and a final inspection to ensure it meets NEC 2023 standards. As a Master Electrician licensed by the St. Louis County Board of Electrical Examiners, we manage the entire permit process for you. This includes submitting the application, scheduling inspections, and providing all required documentation. Handling this red tape is part of our service, ensuring the work is fully legal, insurable, and up to the latest safety codes.

My O'Fallon home was built in 1999. Why do my lights dim every time the fridge or microwave turns on?

Your home's electrical system is now 27 years old, which is a key factor. While the original NM-B Romex wiring in Renaissance neighborhood homes was up to 1999 code, it was sized for the appliance loads of that era. Modern 2026 kitchens often have high-draw devices like air fryers and induction cooktops that demand more current, stressing a panel and circuit layout designed for a different time. This cumulative load on a 150A service can cause noticeable voltage drops, which manifest as dimming lights.

Our O'Fallon neighborhood has underground power lines. Does that affect where the electric meter is or how service is run?

Underground service, like the lateral feed common in Renaissance, does influence the setup. The utility connection comes up through a conduit near your foundation to the meter socket, which is typically on an exterior wall. All wiring from the meter to your main panel inside must be in rigid metal conduit for protection. While underground service avoids overhead tree damage, it requires precise knowledge of trenching depth, conduit sizing, and local amendments to the NEC for a proper and code-compliant installation or repair.
