It's very likely. A 56-year-old NM-B Romex system in your neighborhood was sized for a different era, with far fewer high-draw appliances. Modern microwaves, air fryers, and HVAC equipment can create significant voltage drop on those original circuits. This dimming is a clear sign your electrical capacity is struggling to meet 2026 demands, and an evaluation of your load calculation and panel health is the first step toward a solution.

Treat any burning smell as an immediate fire hazard and shut off power to that circuit at your panel. For an emergency like this, we can typically dispatch from near the Fennimore Memorial Building and be on-site in 3 to 5 minutes using US-18. The priority is rapid response to isolate the fault and prevent an electrical fire, which is why we keep a truck ready for downtown calls.

Your current 100-amp service is likely insufficient, and the presence of a Federal Pacific panel adds a critical safety concern. These panels are known for faulty breakers that fail to trip during overloads, creating a serious fire risk. Adding a heat pump's substantial load requires a full service upgrade to at least 200 amps and the mandatory replacement of that hazardous panel before any new equipment is installed.

Overhead mast service requires you to visually inspect where the utility drop connects to your house. Look for weathering, sagging, or damage to the masthead and conduit, especially after severe weather. The homeowner is responsible for the mast and weatherhead assembly. Any issues here can let moisture into your main panel, so address repairs promptly to maintain a watertight service entrance.

Flickering during Alliant Energy grid disturbances from seasonal thunderstorms is common here. These voltage fluctuations and potential surges absolutely pose a risk to sensitive modern electronics like computers and smart home devices. Installing a whole-house surge protector at your main panel is a fundamental defense, as typical power strips offer inadequate protection for these grid-level events.

Yes, a permit from the Wisconsin Department of Safety and Professional Services (DSPS) is legally required for a panel replacement. As a master electrician, I pull all necessary permits and schedule the final inspection. This ensures the work complies with the current NEC 2020 code and is logged with the utility, which is mandatory for them to reconnect your upgraded service safely and legally.

Winter peak loads from heating systems strain the grid, making brownouts possible. Ensure your heating equipment is serviced and on dedicated circuits. For critical backup, a properly installed and permitted transfer switch for a generator is essential; never use a generator through a household outlet. This setup provides safe, isolated power for essentials during an extended outage.

Yes, the rocky, variable soil common in the Driftless Area can challenge grounding electrode conductivity. A proper ground is non-negotiable for safety and surge dissipation. We test ground resistance at installations to ensure your grounding electrode system meets NEC standards, which is especially important with the moderate surge risk from our hilltop thunderstorms.
