All panel upgrades require a permit from the Exeter Building Department and must be performed by an electrician licensed by the New Hampshire Electricians' Board. The work will be inspected to ensure compliance with the adopted NEC 2020 code, which has specific requirements for AFCI protection, grounding, and working space. As your expert, handling this red tape is part of the job. Using an unlicensed contractor or skipping permits voids insurance and creates serious safety and legal liabilities.

A 56-year-old electrical system from 1970 is often undersized for 2026. Original NM-B Romex wiring in Downtown Exeter homes was designed for a handful of 60-watt bulbs and an outlet per room, not multiple high-wattage kitchen appliances, computers, and entertainment systems running simultaneously. This creates overloaded circuits, leading to voltage drop—the dimming lights you see. Modern living demands more dedicated circuits and often a service panel upgrade to safely distribute power.

This is likely a combination. Unitil's overhead grid in our area faces moderate surge risk from seasonal ice storms, which can cause voltage fluctuations. However, your 1970s-era wiring lacks the whole-house surge protection required by modern NEC standards to shield sensitive electronics. The issue originates on the grid but enters your home. Installing a service entrance surge protective device at your meter is the most effective defense for your smart home systems.

Overhead mast service, standard for many Exeter homes of your era, has specific vulnerabilities. The mast head and weatherhead can degrade, allowing moisture to enter your service cables. The mast itself must be securely anchored; ice load from winter storms can pull it away from the house. Visually inspect for any sagging, corrosion, or damaged conduit. Any tree contact, as noted, is a hazard. Upgrading this mast is often part of a full service upgrade to support modern electrical demands.

Winter lows near -10°F and heating surges strain the grid. First, ensure your heating system is on its own, properly sized circuit. Consider a professionally installed standby generator with an automatic transfer switch to maintain heat and refrigeration during extended outages. For brownouts or brief surges, the whole-house surge protector mentioned earlier is critical. These steps protect both your family's comfort and your major appliances from damaging voltage sags.

Call a licensed electrician immediately for a burning smell, as it indicates a potential fire hazard. A local master electrician familiar with Downtown Exeter can typically dispatch from a central point like the Exeter Town Hall. Using NH-101, a response time of 5-8 minutes to most neighborhoods is standard for urgent calls. Do not attempt to reset any breakers or touch the panel until a professional assesses the situation.

Absolutely. The heavy tree canopy common around Downtown Exeter and the Exeter Town Hall is a primary cause of power quality issues. Branches rubbing against overhead service lines can cause interference, arcing, and momentary outages. During storms, falling limbs are the main cause of prolonged power loss. Furthermore, rocky New England soil under that canopy can challenge grounding electrode installation, making a proper ground connection more difficult but no less vital for safety.

No, you cannot safely add those major loads with your current setup. A Federal Pacific panel is a known fire hazard due to breakers that can fail to trip, and a 100-amp service from 1970 lacks the capacity. Installing a Level 2 EV charger or modern heat pump requires a new, code-compliant 200-amp panel and service upgrade. This is a multi-step project that starts with replacing the dangerous panel before any new circuits are added.
