Your existing 100A service with its original 1962-era panel is not adequate for those additions. A Level 2 EV charger alone can draw 40-50 amps, and a heat pump requires another dedicated circuit. More critically, many panels from that era in Highland Park are the recalled Federal Pacific brand, which pose a serious fire risk as they can fail to trip during an overload. Installing major new loads on this system is unsafe; a full service upgrade to 200A with a modern, code-compliant panel is the required first step.

For an urgent safety issue like a burning smell, we treat it as a priority dispatch. From our base near the Ravinia Festival, we can typically be on site in Highland Park within 10 minutes using US-41. The immediate step is to shut off the main breaker if it's safe to do so. Our first priority upon arrival is to secure the hazard, identify the source—often a failing breaker or overheated connection—and make the system safe before any restoration.

Your 64-year-old cloth-jacketed copper wiring is the core issue. While the copper itself is good, the old insulation becomes brittle and less efficient over time. Modern appliances in a 2026 home draw significantly more power than a 1962 system was designed for, causing voltage drop under load, which you see as dimming lights. This is a common strain for original systems in Highland Park neighborhoods, indicating the wiring and likely the 100A panel are operating at their safe limit.

Any service panel upgrade requires a permit from the Highland Park Building Division and must be performed by a licensed electrician, as mandated by the Illinois Department of Financial and Professional Regulation. The work will be inspected to ensure it complies with the 2023 National Electrical Code (NEC) and local amendments. As your Master Electrician, I handle the entire permit process—application, scheduling inspections, and providing the required documentation. This ensures your upgrade is not only safer and more capable but also fully legal and documented for future home sales.

Flickering during storms points to grid-side disturbances, which are common with ComEd's overhead lines during our moderate-to-severe seasonal thunderstorms. However, your home's internal protection is also a factor. Old wiring and panels offer little defense against these surges. Modern smart home electronics are sensitive to even minor voltage fluctuations. Installing a whole-house surge protector at your main panel is a critical upgrade to shield your devices from both external grid surges and internal spikes from large appliances cycling on and off.

Preparation focuses on reliability and safety. For winter ice storms that can bring down power lines, consider a permanently installed generator with an automatic transfer switch to keep heat and sump pumps running. For summer brownouts caused by peak AC demand, ensure your panel and wiring connections are tight—loose connections heat up more under low-voltage conditions. In both seasons, a whole-house surge protector is advisable to handle the surges that inevitably occur when grid power is restored after an outage.

Overhead mast service, standard for your 1962 home, has specific vulnerabilities. The mast itself must be securely anchored; winter ice and high winds can strain it. The service drop wires from the pole are exposed to tree limbs and weather. We also check where the service entrance cables enter your meter socket and main panel, as these are common points for water infiltration and corrosion over decades. Ensuring these entry points are properly sealed and that the mast hardware is not rusted is a key part of maintaining a safe overhead service.

Absolutely. The heavy tree canopy common in this area directly impacts your electrical health. Branches rubbing against overhead service lines can cause interference, noise, and even create a fire hazard. More subtly, tree root systems can disrupt your home's grounding electrode system if they've grown around or damaged the underground grounding rod. Proper grounding is essential for safety and surge protection. It's wise to have an electrician inspect both your overhead service mast connection and your grounding system during a routine evaluation.
