Overhead service masts require periodic visual inspection. Focus on the point where the mast enters your roofline for signs of rust, paint failure, or separation, which can allow water into your structure. Also check for tree limbs within 10 feet of the service drop conductors. In winter, be mindful of heavy ice accumulation pulling on the mast head or lines, as this stress can damage the service entrance hardware.

Yes, the dense tree cover common in Somersworth's terrain can directly impact electrical health. Overhead service lines running through heavy canopy are susceptible to wind-induced movement and minor faults, even on calm days, which cause flickering. Furthermore, rocky soil in hilly areas can challenge grounding electrode systems, making proper ground resistance checks vital for safety and stable voltage.

For an active emergency like a burning smell, we prioritize immediate dispatch. From Somersworth City Hall, we use NH-108 for direct access throughout the Downtown neighborhood, typically arriving within 3 to 5 minutes. Your first action should be to safely turn off the main breaker at the service panel if you can do so without risk, then evacuate the immediate area and call for help.

Your electrical system is over 55 years old. NM-B Romex wiring from that era, while still safe if undisturbed, was installed for a different era of appliance use. Modern 2026 loads like microwaves, computers, and space heaters demand more consistent power. The issue is likely undersized branch circuits from the original design, which can't deliver the steady amperage today's devices require without causing noticeable voltage drop.

A 100-amp service from 1970 is almost certainly insufficient for those additions and may not be safe if it's a Federal Pacific panel. Those panels have a known, widespread failure risk and are not code-compliant. Adding a heat pump and Level 2 EV charger requires a service upgrade to 200 amps. We must first replace any Federal Pacific equipment with a modern panel featuring AFCI breakers to establish a safe foundation for expansion.

This points to transient voltage surges, a common issue here. The Eversource grid in our area faces moderate surge risk, particularly from seasonal ice storms which can cause line faults and power flickers. These micro-surges are often invisible but are harsh on modern electronics. The solution isn't just better grid power; it requires installing a whole-house surge protector at your main panel to clamp these spikes before they reach your devices.

Winter preparedness centers on reliable heat and surge protection. The peak heating surge can strain an older 100-amp panel. Have a licensed electrician verify your furnace circuit and emergency heat strips are on dedicated, properly sized breakers. For extended outages common with ice storms, consider a professionally installed generator interlock kit. This provides safe backup power without the risks of using extension cords through windows.

A panel replacement always requires a permit and inspection in Somersworth. Only a master electrician licensed by the New Hampshire Electricians Board can pull this permit from the Development Services Department. We handle this red tape, ensuring the work meets NEC 2020 standards for safety devices like AFCI breakers and proper labeling. This formal process protects your home's value and insurability.
