Your 88-year-old electrical system is facing a fundamental capacity issue. Knob and tube wiring from 1938 was designed for lighting circuits, not the continuous high-wattage loads of modern appliances. A microwave and a space heater operating simultaneously can easily overload a single, antiquated circuit. This causes voltage drop, which manifests as dimming lights, and creates a significant fire risk due to overheating insulation.

With that setup, it is not just difficult—it is unsafe to attempt. A Federal Pacific panel is a known fire hazard due to breakers that can fail to trip during an overload. Furthermore, a 60-amp service lacks the capacity for major new loads. Installing a Level 2 charger or a heat pump requires a full service upgrade to at least 200 amps and the mandatory replacement of that hazardous panel. This is a foundational project that must come first.

Inspect the mast head and the conduit for rust, damage, or any sagging. The service drop wires should have clear clearance from trees and the roof. Overhead services are common here, but they are vulnerable to falling branches and ice accumulation. If you notice any wear on the mast or the weatherhead, have it assessed. Any upgrade to your electrical service will involve bringing this mast and entrance cable up to current code standards for your safety.

Winter preparedness starts with ensuring your heating system's electrical circuits are robust and on dedicated breakers. For extended outages, a properly installed generator with a transfer switch is key—never use a portable generator plugged directly into a household outlet, as it can back-feed and kill utility workers. Given the surge risk from ice-damaged lines, verifying your surge protection is active before peak season is a prudent step.

It is likely a combination of both. Eversource's overhead lines in our area are susceptible to interference from seasonal ice storms, which can cause momentary surges and flickers. However, knob and tube wiring provides no inherent surge protection and its degraded connections can amplify these problems. To protect sensitive electronics, a whole-house surge protector installed at your upgraded service panel is a critical defense against grid-borne transients.

Yes, all work must comply with the 2020 National Electrical Code, which is adopted statewide. You will need an electrical permit from the Greenville Building Department, and the work must be performed by a master electrician licensed by the New Hampshire Electricians Board. As your contractor, I handle pulling the permit and scheduling the required inspections. This process ensures your upgrade is documented, safe, and adds value to your home.

Absolutely. Rocky, high-resistance soil makes establishing a low-resistance grounding electrode system more challenging. A proper ground is essential for safety, as it gives fault current a direct path to earth and stabilizes voltage. On a hillside, we often need to drive multiple grounding rods or use a concrete-encased electrode (Ufer ground) to meet NEC requirements. Poor grounding can lead to erratic appliance behavior and reduce the effectiveness of surge protection.

For a burning smell, we treat it as an urgent safety dispatch. From our starting point near the Souhegan River Bridge, we can typically reach most Greenville Center addresses via NH-31 within 3 to 5 minutes. Please turn off the main breaker at your service panel if it is safe to do so and exit the immediate area. A burning odor often indicates an active failure at a connection or within a Federal Pacific panel, which requires immediate professional diagnosis.
