Your home's electrical system is now 50 years old. In 1976, a 100-amp service with NM-B Romex wiring was standard, designed for far fewer appliances than a modern household uses. Today's kitchens and entertainment centers demand more power, and original circuits from that era often lack the capacity for simultaneous high-draw devices. This overloads the circuit, causing voltage drop, which manifests as dimming lights.

Inspect the mast head and the service drop cables for weathering, especially after coastal storms. Look for cracked or missing weatherheads, frayed cable sheathing, or any signs of corrosion on the mast itself. The mast should be securely anchored to your house without sagging. Any damage here is the utility's responsibility up to the weatherhead, but the mast and connections to your meter are yours and require a licensed electrician to repair.

Coastal storms bring a moderate surge risk from Unitil's overhead lines, which can send damaging spikes into your home's electronics. While your internal wiring may be part of the equation, the primary defense is a whole-house surge protector installed at your main electrical panel. This device acts as a barrier, clamping dangerous voltage spikes before they reach your sensitive electronics and network equipment.

Proceeding with a major upgrade like a heat pump without addressing your Federal Pacific panel is not advisable. These panels have a known failure rate for breakers not tripping during an overload, which is a significant fire hazard. Furthermore, a 100-amp service from 1976 is often at its limit with modern loads; adding a heat pump's dedicated circuit typically requires a service upgrade to 200 amps for safe, reliable operation.

Yes, sandy soil has high electrical resistance, which can impair the effectiveness of your grounding electrode system. A proper ground is critical for safety, as it directs fault currents safely into the earth. We often need to drive additional ground rods or use a ground ring to achieve the low-resistance path required by code, especially in older Hampton Beach homes where the original ground may have degraded.

Any service upgrade or panel replacement requires a permit from the Hampton Building Department and a final inspection. As a Master Electrician licensed by the New Hampshire Electricians Board, I handle the entire process: pulling the permit, performing the work to NEC 2023 standards, and coordinating the inspection. This ensures the installation is documented, safe, and compliant, which is crucial for both your safety and home insurance.

For a burning smell, we treat it as an immediate safety dispatch. From our staging near Hampton Beach State Park, we can typically be on-site in your neighborhood within 8 to 12 minutes using NH-101. Your first action should be to go to your main panel and shut off the breaker for that circuit if it's safe to do so. We will diagnose the source, which is often a failing connection at an outlet or within the panel.

For winter preparedness, ensure your heating system's electrical components are serviced and consider a hardwired backup generator with a proper transfer switch. Summer brownouts, caused by grid strain from widespread AC use, underscore the need for that whole-house surge protection. Managing your load by staggering high-use appliances can also help prevent tripping your main breaker during peak demand.
