Your home's NM-B Romex wiring is over 50 years old, installed around 1972. While the copper itself is sound, the system was designed for far fewer and less powerful appliances than we use today. A 100-amp service panel, common for its era, is now often overloaded by modern air conditioners, kitchen gadgets, and entertainment systems all running simultaneously. This voltage drop under heavy load is what causes your lights to dim.

Winter temperatures dipping into the teens place a heavy strain on heating systems, creating peak demand that can lead to brownouts. Preparing involves ensuring your heating equipment is on a dedicated, properly sized circuit and that all connections at the panel and within the system are tight. For extended outages, a permanently installed generator with an automatic transfer switch is the safest and most reliable backup, keeping essential circuits powered without the risks of extension cords or portable units.

The KUB grid, especially in our region near the foothills, experiences frequent and powerful lightning strikes. These surges can easily overwhelm basic power strips and travel through your home's wiring. To protect sensitive smart home electronics, a professionally installed whole-house surge protector at your main panel is recommended. This device acts as a first line of defense, clamping down on voltage spikes before they reach your circuits.

A Federal Pacific panel, common in homes from that period, presents a significant safety risk due to a known failure to trip during overloads. Before considering any major addition like a Level 2 EV charger or a heat pump, replacing this panel is non-negotiable. Furthermore, your existing 100-amp service is insufficient for these high-demand appliances; a full service upgrade to 200 amps is the required foundation for a safe, modern electrical system.

Overhead service masts, while common, are vulnerable points. You should visually inspect where the utility cable attaches to your house for any signs of wear, sagging, or damage from weather or tree limbs. The mast itself must be securely mounted to your home's structure. Any work on this point of connection requires coordination with KUB and must be performed by a licensed electrician to meet strict clearance and anchoring codes.

The rocky, uneven soil common in these foothills can challenge the effectiveness of your home's grounding electrode system, which is critical for safety. Furthermore, the heavy tree canopy in these areas can cause service line interference during high winds or ice accumulation, leading to flickering or momentary outages. An electrician can test your grounding resistance and inspect the masthead where the utility service attaches to your home to ensure integrity.

All panel upgrades in Knoxville require a permit from the Knoxville Plans Review and Inspections Division and a final inspection to ensure compliance with the 2020 National Electrical Code. Tennessee law mandates that this work be performed by a contractor licensed by the Tennessee Department of Commerce and Insurance. As a Master Electrician, I handle the entire permit process, ensuring the installation meets all current safety standards and passes inspection without issue for you.

We dispatch immediately for electrical emergencies. From our starting point near Ijams Nature Center, we can be at most John Sevier/South Knoxville homes in 12-15 minutes using US-441 / Chapman Highway. Upon arrival, our first priority is to make the situation safe by identifying and isolating the fault, which is often a failing connection or overloaded circuit causing that burning odor.
