The utility, Unitil, owns and maintains the overhead lines from the pole up to the connection point on your mast (the pipe on your roof). You, as the homeowner, are responsible for the mast, the weatherhead, and all wiring from that point down into your meter and main panel. If the line is sagging or damaged, contact Unitil. If the mast is leaning or the connection at your roof is compromised, that requires a licensed electrician to repair to prevent a fire or power loss.

For an active electrical emergency, dispatch from our shop near Prescott Park puts us on I-95 in under a minute. We aim for a 5-8 minute response to the South End. A burning smell indicates an immediate fire risk—turn off the main breaker at your panel if it's safe to do so and evacuate the area. Our priority is securing the hazard first, then diagnosing the failed component, which is often an overloaded wire or a failing connection at an outlet.

A 100-amp service from 1958, especially with a Federal Pacific panel, is not suitable for adding major new loads. Federal Pacific panels are a known fire hazard due to breakers that can fail to trip during an overload. Installing a Level 2 EV charger or a heat pump typically requires a modern 200-amp service to handle the sustained current. The process starts with replacing the hazardous panel and upgrading your service entrance wiring, which must be permitted and inspected by the city.

The flat, often moist soil of the coastal plain can actually provide a good ground connection, which is critical for safety. However, high water tables in these areas can accelerate corrosion on underground grounding electrodes like metal rods. We recommend testing your grounding system's resistance every few years to ensure it meets NEC standards. Proper grounding is your first line of defense against lightning strikes and faults, directing dangerous current safely into the earth.

All major electrical work in Portsmouth requires a permit from the Portsmouth Inspection Department and must comply with the 2023 National Electrical Code (NEC). The work must be performed by an electrician licensed by the New Hampshire Electricians Licensing Board. We handle the permit paperwork and schedule the required inspections. This process ensures the installation is safe, documented for future homeowners, and meets the latest standards for arc-fault and ground-fault protection now mandated by code.

Your electrical system is 68 years old, and the original cloth-jacketed copper wiring in many South End homes was designed for a much lower power demand. Modern 2026 appliances like air fryers and induction stoves draw significantly more current, which can overload the circuit's capacity and insulation. This causes breakers to trip as a safety measure and can lead to dangerous overheating behind your walls. Upgrading the wiring and panel capacity resolves this by providing a safe path for the power your home now requires.

Winter heating surges and ice storms strain both the grid and your home's electrical system. Ensure your heating equipment is on dedicated, properly sized circuits to prevent overloads. Consider installing a generator with a proper transfer switch to maintain heat during an outage. Proactively having your service mast, overhead lines, and panel connections inspected can prevent weather-related failures. Surge protection is also wise, as ice accumulation on lines can cause sudden power restorations that damage electronics.

Flickering often points to a loose connection, either at your main panel, a junction box, or the utility's service drop. While Unitil's grid in Portsmouth faces moderate surge risks from seasonal ice storms, internal house wiring is a more common culprit in older homes. A diagnostic test can isolate the issue. For protection, a whole-house surge protector installed at your panel is recommended to safeguard sensitive electronics from both external and internal voltage spikes.
