Winter's -10°F lows and heating surge demand strain older systems. Ice storms can knock out overhead lines for extended periods. We recommend installing a generator transfer switch and ensuring your heating system's circuits are properly dedicated and protected. Proactive maintenance, like tightening connections in your panel, also prevents failures when you need heat the most during a brownout or outage.

Flickering often points to loose connections in your home's wiring or at the service entrance. However, Public Service of New Hampshire's grid faces moderate surge risk from seasonal ice storms and lightning. These grid disturbances send voltage spikes that can damage sensitive electronics like routers and computers. Installing whole-house surge protection at your main panel defends your entire home against these external surges.

Homes here built around 1976 have 50-year-old electrical systems. Original NM-B Romex wiring and a 100-amp panel were designed for far fewer devices than we use today. Modern appliances like air conditioners, microwaves, and home offices create simultaneous loads that can overload circuits, causing dimming lights and tripped breakers. An evaluation can determine if your system needs circuit balancing or a capacity upgrade to meet 2026 demands.

Overhead mast service is common here. The mast, weatherhead, and service drop wires are exposed to ice, wind, and tree damage. It's crucial to keep the path from the utility pole to your house clear of branches. We also check that the mast is securely anchored and that the SE cable entering your meter is intact. Any sagging or damage to these components requires immediate professional repair to prevent a service pull-down or fire hazard.

For an emergency like a burning smell, we treat it as a priority dispatch. From the Pembroke Town Library, we can typically be on US-3 and at your door in 5 to 8 minutes. The first step is to safely shut off power at the main breaker if possible. This immediate response is critical to prevent a potential electrical fire from spreading within the walls.

A Federal Pacific panel is a significant safety hazard and must be replaced before any major upgrade. Your 100-amp service from 1976 also lacks the capacity for a Level 2 EV charger, which typically requires a dedicated 50-amp circuit. We would first replace the hazardous panel and likely upgrade your service to 200 amps. This creates a safe, modern foundation capable of supporting an EV charger, heat pumps, and future loads.

The process starts with a licensed master electrician filing detailed plans showing load calculations and compliance with the current NEC 2020 code. The Pembroke Building Department reviews this before issuing a permit. After the upgrade, the work must be inspected and approved. As a licensee of the New Hampshire Electricians Board, I handle this entire process, ensuring all red tape is managed and your upgrade is fully legal and insurable.

Pembroke Hill's heavy tree canopy and rolling hills directly impact electrical health. Tree limbs contacting overhead service lines can cause flickering, noise, and intermittent faults. Furthermore, rocky soil common in hilly areas can challenge proper grounding electrode installation, which is vital for safety. An inspection can assess line clearance and test your grounding system's resistance to ensure it meets code.
