FAQs
What's involved in getting a permit for a panel upgrade from the City of Des Peres?
All major electrical work requires a permit from the City of Des Peres Department of Public Works and a final inspection. As a Master Electrician licensed by the St. Louis County Board of Electrical Examiners, I handle the permit paperwork and ensure the installation meets all requirements of the adopted 2023 National Electrical Code. This compliance is not just red tape; it's your assurance the work is done safely and to the latest standards.
My Des Peres home was built in 1975. Why do the lights dim when I run the microwave and air conditioner together?
Your electrical system is over 50 years old. Homes in the Clayton Road Corridor from that era were wired with NM-B Romex for lighting and small appliance circuits, not the high-demand devices common in 2026. Modern kitchens and central air conditioning can overwhelm the original circuit capacity, causing voltage drop that manifests as dimming lights. This is a sign the system is undersized for current loads.
I have a Federal Pacific panel and want to add a Level 2 EV charger. Is my 100-amp service enough?
No, your current setup presents two critical issues. First, Federal Pacific panels are a known fire hazard and should be replaced immediately. Second, a 100-amp service from 1975 cannot safely support adding a Level 2 EV charger or a modern heat pump. The upgrade process starts with replacing the faulty panel and almost always requires a service capacity increase to 200 amps to handle these new continuous loads.
Could the big trees in my yard near Des Peres Park be affecting my home's power quality?
Yes, the rolling hills and mature tree canopy common here can impact electrical health. Overhead service lines running through trees are susceptible to interference, abrasion, and damage during high winds, which can cause flickering or outages. Furthermore, the rocky soil found in some areas can complicate the installation of an effective grounding electrode system, which is vital for safety.
We have overhead lines on our street. What does that mean for our home's electrical service?
An overhead mast service means your power comes from utility lines via a weatherhead on your roof. This exposed entry point is vulnerable to storm damage from the mature trees in our area. It also dictates the location of your meter and service entrance conductors. When considering a service upgrade, the mast assembly and its roof penetration must be evaluated and likely updated to meet current NEC code for weather resistance and structural support.
There's a burning smell from my electrical panel. How fast can an electrician get to my house near Des Peres Park?
For a burning smell, which indicates a potential fire hazard, you should call for immediate dispatch. From our base near the park, we can typically route via I-270 and reach most homes in the Des Peres area within 5 to 8 minutes. Please turn off the main breaker at the panel if it is safe to do so while you wait.
Why do my lights flicker and my smart devices reset during storms in Des Peres?
Flickering during storms is often due to grid disturbances from Ameren Missouri. Our area has a high surge risk from frequent lightning, which can send damaging voltage spikes through your wiring. These micro-surges are particularly hard on sensitive smart home electronics and can degrade them over time. A whole-home surge protector installed at your main panel is the most effective defense.
How should I prepare my home's electrical system for a Missouri ice storm or a summer brownout?
For winter ice storms that can bring down power lines, a permanently installed generator with an automatic transfer switch is the most reliable solution. For summer brownouts caused by peak AC demand, ensuring your electrical panel and connections are in good health is key. In both scenarios, point-of-use surge protection for electronics is a wise investment to guard against power restoration surges.
