It's often both. Public Service of New Hampshire (Eversource) manages the grid, and seasonal ice storms in our area cause moderate surge risk from downed lines and switching operations. Your 1952-era wiring lacks the whole-house surge protection needed for sensitive 2026 electronics. We install surge protection at the main panel to defend against external grid events and internal surges from large appliances cycling on and off.

Your home's electrical system is 74 years old. The original cloth-jacketed copper wiring was designed for a few lamps and a radio, not the simultaneous high-wattage demands of 2026 appliances. Dimming lights indicate voltage drop across undersized circuits, a common issue in historic neighborhoods. This constant strain can degrade the old insulation, creating a fire hazard that requires a professional evaluation and likely a service upgrade.

For a burning smell, we treat it as an immediate fire risk. From our dispatch point at Hillsborough Town Hall, we can typically be on-site in Downtown Hillsborough within 5 minutes via NH-9. Your first action should be to shut off the breaker for that circuit at the main panel and call. We prioritize these calls to prevent a smoldering wire inside your wall from igniting.

Overhead mast service is standard here but has specific vulnerabilities. The mast head or weatherhead can degrade, allowing moisture and ice to enter the service entrance cables. In heavy snow or ice storms, the weight on the overhead drop line can strain the mast or even pull it from the house. We inspect the mast's structural integrity, the condition of the service entrance conductors, and the seal where they enter your meter base to prevent water damage and connection failures.

Winter heating surges are the peak season for electrical failures here. Before a storm, ensure your heating system is serviced and all vents are clear. For extended outages, a properly installed generator with a transfer switch is the safest backup. We also recommend installing AFCI breakers in living areas, as they are far more effective than old fuses at preventing arc faults—a common cause of electrical fires when systems are stressed by continuous heating loads.

All major electrical work requires a permit from the Hillsborough Building Department and must comply with the NEC 2020, which is the state-adopted code. As a Master Electrician licensed by the New Hampshire Electricians Board, I handle the permit application, scheduling of inspections, and ensure the installation meets all current safety standards for AFCI and GFCI protection. This process protects your home's value and ensures the system is insurable.

A 60-amp service from 1952 is almost certainly insufficient and may not be safe, especially if the panel is a Federal Pacific brand, which is known for faulty breakers that fail to trip. Supporting a modern heat pump, let alone an EV charger, requires a dedicated 240-volt circuit and significant additional capacity. The project starts with a full load calculation and almost always requires a service upgrade to at least 200 amps to handle the new load safely.

Yes, the heavy forest canopy in these rolling hills directly impacts electrical health. Tree limbs contacting overhead service drops can cause intermittent faults and voltage fluctuations, leading to flickering. Furthermore, rocky soil common in our terrain can compromise grounding electrode conductivity, which is critical for safety. An inspection should check both the utility service mast connection and the integrity of your home's grounding system to the earth.
