For a burning smell, we treat it as a critical emergency. Dispatched from near Dartmouth Green, we can typically be on-site in Occom Ridge within 5 to 8 minutes via I-91. Our priority is immediate isolation of the fault to prevent a fire. Please turn off the breaker for that circuit if it's safe to do so and evacuate the area around the outlet until we arrive to assess and repair the damaged connection.

Yes, Federal Pacific panels are a serious concern due to a known failure of their breakers to trip during an overload, creating a major fire hazard. Replacing that panel is your top safety priority. Furthermore, a 100-amp service from 1973 cannot safely support adding a Level 2 EV charger or a modern heat pump system. A full service upgrade to 200 amps is the necessary foundation for both eliminating the hazard and enabling future electrification.

This is likely a combination of both. Liberty Utilities' overhead lines in our region face moderate surge risk from seasonal ice storms, which can cause momentary voltage fluctuations or dips. However, your home's electrical system should have the first line of defense. Installing a whole-house surge protector at your main panel is a critical upgrade to shield sensitive 2026 electronics from these grid disturbances, supplementing the utility's equipment.

Preparation involves both protection and backup. First, ensure you have a properly installed and permitted generator interlock kit on your panel for safe backup power; portable generators connected incorrectly can backfeed the grid and kill utility workers. Given the winter heating surge, prioritize circuits for your furnace, well pump, and refrigerator. Whole-house surge protection also guards against damaging surges when grid power is restored after an outage when power is restored.

Your overhead mast service is standard for many Hanover homes. The primary con is exposure; it's vulnerable to falling branches from our heavy tree canopy and ice accumulation during winter storms, which can lead to outages. The pro is accessibility for repairs and for future service upgrades. When upgrading your panel and mast head for a 200-amp service, the overhead connection often simplifies the utility's work compared to trenching for a new underground line.

Absolutely. The heavy tree canopy common in this area can cause physical damage to overhead service drops during storms and create interference on lines. More critically, the rocky, rolling topography makes achieving a low-resistance ground for your electrical system difficult. A proper grounding electrode system is essential for safety and surge dissipation, and often requires specialized installation techniques in this terrain to meet NEC 2023 requirements.

All panel replacements and service upgrades in Hanover require a permit from the Hanover Building Inspection Department and a subsequent inspection. As a Master Electrician licensed by the New Hampshire Electricians' Board, I handle securing that permit and ensuring the installation complies fully with NEC 2023. This legal process isn't red tape; it's a vital check that the work meets current safety standards, protects your home, and is properly documented for future homeowners and your insurance company.

Your home's original NM-B Romex wiring, now over 50 years old, was installed for a different era of power consumption. A 100-amp panel from 1973 was designed for basic lighting and a few large appliances, not the multiple high-wattage countertop devices, computers, and entertainment systems a 2026 household runs simultaneously. This shared load on aging circuits causes voltage drop, which you see as dimming lights—a clear sign your electrical infrastructure is struggling to meet modern demand.
