Q&A

I'm near Sievers Park and my power is out with a burning smell. How fast can a Master Electrician get here?

We prioritize emergency calls like this. From our dispatch near Sievers Park, we can typically reach homes in the Jennings Station area within 5-8 minutes using I-70 for the main route. A burning odor indicates an active fault that requires immediate shutdown at the main breaker to prevent a fire. Our first-response truck is equipped to secure the hazard, diagnose the source—often a failing connection at an old Federal Pacific panel—and begin the safe restoration process.

My power comes in on an overhead mast. What are the common issues with this setup in Jennings?

Overhead service masts, while common for homes of your era, have specific vulnerabilities. The mast itself can corrode or become loose at the roofline, and the service drop wires from the utility pole can degrade over decades. During severe storms, falling branches are a primary cause of outage and damage. We also check that the mast and weatherhead are properly sized and secured for current St. Louis County codes, as an improper installation can lead to water infiltration into your panel, creating a major shock and corrosion hazard.

We have rolling terrain and big trees near Sievers Park. Could that be causing our lights to flicker?

Yes, the rolling suburban terrain and mature tree canopy common around Jennings Station can contribute to power quality issues. Overhead service lines swaying in wind or making contact with tree branches cause intermittent faults that manifest as flickering lights. Furthermore, rocky or variable soil conditions in such terrain can compromise your home's grounding electrode system over time. An improper ground fails to stabilize voltage and can increase surge damage risk, making a professional evaluation of your exterior grounding rods a wise step.

The lights in my 70-year-old Jennings Station home dim when the AC kicks on. Is my old wiring just worn out?

Your home's original 1956 cloth-jacketed copper wiring is likely part of the problem. At 70 years old, the insulation becomes brittle and loses its protective qualities. More critically, a 100-amp panel, standard for its era, was never designed to handle the cumulative load of a modern 2026 household running multiple high-draw appliances, computers, and HVAC systems simultaneously. This creates voltage drops, seen as dimming lights, and poses a significant overheating risk behind your walls.

How should I prepare my Jennings home's electrical system for winter ice storms and summer brownouts?

Preparation focuses on safety and backup power. For winter, have a licensed electrician inspect your service mast and overhead connections for integrity, as ice load can bring lines down. For sustained summer brownouts, consider a professionally installed manual transfer switch and generator to safely power essential circuits, avoiding the deadly backfeed hazard of using a simple extension cord. Whole-house surge protection is a year-round investment to shield electronics from grid instability during both seasons.

Can my 1956 Jennings home with a 100-amp panel safely add a Level 2 EV charger or a new heat pump?

Safely, no. A 100-amp service from 1956 is already operating at or near its designed capacity with today's basic appliances. Adding a 240-volt, 40-50 amp EV charger or a heat pump circuit would dangerously overload the system, risking constant breaker trips, damaged wiring, and fire. This is especially critical if your panel is the recalled Federal Pacific brand, known for breakers that fail to trip during an overload. A full service upgrade to 200 amps is the necessary first step for these modern loads.

My smart TVs and routers keep getting fried during Ameren Missouri summer storms. What's going on?

Frequent summer thunderstorms in our region create high surge risk on the Ameren Missouri grid. These voltage spikes travel into your home, seeking the path of least resistance—often your expensive electronics. Flickering lights are a common warning sign. While whole-house surge protective devices installed at your service panel are the most robust defense, ensuring your home's grounding electrode system is intact is equally vital. Proper grounding gives that dangerous surge energy a safe path to earth, away from your devices.

I need a panel upgrade. What's involved with permits and inspections in St. Louis County?

Any service upgrade or major panel replacement requires a permit from the St. Louis County Department of Public Works and a final inspection to ensure compliance with the 2023 NEC. As a Master Electrician licensed by the St. Louis County Board of Electrical Examiners, I handle the entire permit process. The inspection verifies the safe installation of the new equipment, proper grounding, correct load calculations, and that the work meets all modern safety codes—which is non-negotiable when dealing with the inherent risks of upgrading a 70-year-old system.
