Q&A
Our smart TVs and computers keep getting reset during Ameren Missouri thunderstorms. Are power surges just something we have to live with?
No, frequent surges are not normal and can destroy modern electronics. Ameren Missouri's grid, combined with our high summer thunderstorm risk, creates transient voltage spikes that travel into your home. A whole-house surge protector installed at your main service panel is the professional solution. It diverts these massive surges to ground before they reach your sensitive devices, working in tandem with point-of-use protectors for layered defense.
We have overhead power lines coming to our house. What specific maintenance should we be aware of compared to underground service?
Overhead service requires vigilance for weather and tree-related damage. Regularly inspect the masthead and service drop cable for cracks, animal nests, or wear where it enters your house. Ensure tree limbs are trimmed well back from the lines. The grounding system for overhead service is also critical, as the mast and neutral connection are the first line of defense for lightning strikes. An annual inspection by a licensed electrician can identify wear before it causes an outage or hazard.
What permits and codes are involved for a main panel upgrade in St. Louis County, and who handles that?
A service upgrade requires a permit from the St. Louis County Department of Planning and Development and must comply with the 2023 National Electrical Code (NEC). As a master electrician licensed by the Missouri Division of Professional Registration, I handle the entire process: filing detailed plans, scheduling inspections, and ensuring the installation meets all code for grounding, AFCI protection, and load calculations. You receive the final inspection certificate, which is crucial for insurance and home value.
We live in the rolling hills near St. Louis Community College-Meramec and have intermittent electrical noise in our audio system. Could the terrain be a factor?
Yes, the terrain can influence electrical quality. Rolling hills often mean longer utility service runs and complex grounding conditions. Rocky or variable soil can challenge your home's grounding electrode system, leading to poor earth contact. This can cause ground loops and introduce noise into sensitive audio/video equipment. A master electrician can test your grounding resistance and bonding to ensure a stable, low-impedance path, which often resolves these interference issues.
Our lights dim when the AC kicks on, and we can't run the microwave and toaster at the same time. Our home was built in 1968. Is this just an old house problem in the Marlborough Residential District?
This is a capacity issue, not just an age issue. Your 58-year-old electrical system was designed for a different era, with its original cloth-jacketed copper wiring and 100-amp service. Modern 2026 appliance loads, especially in summer, simply exceed that design. The wiring insulation can become brittle, and the panel's bus bars may not handle the sustained demand, creating a fire risk that requires a professional assessment and likely a service upgrade.
Our power went out and we smell something burning from an outlet. How fast can an electrician get here from near St. Louis Community College-Meramec?
For a burning smell, we treat it as an immediate fire hazard and dispatch directly. From our base near the college, we can take I-44 and be at your door in the Marlborough area within that 8-12 minute window. Do not wait. Turn off the breaker for that circuit at your main panel if it is safe to do so, and evacuate the area immediately. Our priority is isolating the fault to prevent an electrical fire.
We found a Federal Pacific panel in our 1968 home and want to add a heat pump and maybe an EV charger. Is this even possible?
Adding major loads to a Federal Pacific panel is not safe. These panels are known for faulty breakers that fail to trip during overloads, a critical fire hazard. Your existing 100-amp service is also insufficient for a Level 2 EV charger or a new heat pump. The first step is a mandatory panel replacement with a modern, UL-listed unit and a service upgrade to 200 amps. This creates the safe, code-compliant foundation for all future upgrades.
How can we prepare our home's electrical system for Missouri ice storms and summer brownouts?
Preparation focuses on safety and backup power. For winter ice storms that can bring down lines, a professionally installed manual transfer switch and generator inlet lets you safely back up essential circuits. For summer brownouts from AC demand spikes, ensure your service connections and panel are in good condition to handle voltage dips. In both scenarios, whole-house surge protection is critical, as grid instability often causes damaging power surges.
