Homes from 1970 were designed for a different era of power consumption, with an average of 8-10 circuits. Your original NM-B Romex wiring, now 56 years old, was likely installed for a 100-amp service that supported basics like a refrigerator and a few lights. Modern 2026 kitchens and home offices demand far more concurrent power. That dimming indicates your system is overloaded at the bus bars, struggling to supply your microwave, AC, computer, and phone chargers all at once.

Your Federal Pacific panel is a known hazard; its breakers have a high failure rate and should be replaced regardless of other plans. Adding a 40-50 amp Level 2 EV charger to an existing 100-amp service from 1970 is not feasible. It would require a full service upgrade to 200 amps. We must first replace the dangerous panel with a modern one equipped with AFCI breakers, then upgrade the service entrance conductors and meter base to support the new charger and other modern loads safely.

The moist, sandy soil common in Groton Heights can accelerate corrosion on underground grounding electrodes like ground rods. This increases ground resistance, compromising the safety path for fault currents. During your next panel inspection, we should test the grounding electrode system's resistance. We may need to drive additional rods or install a concrete-encased electrode (Ufer ground) to achieve the low-resistance connection required by the NEC for reliable operation of your breakers.

Any service upgrade or panel replacement requires a permit from the Groton Building Department and a final inspection. As a Master Electrician licensed by the Connecticut Department of Consumer Protection, I handle that paperwork. The work must be performed to the current adopted code, which is the NEC 2023. This ensures safety features like AFCI protection for living areas and correct sizing for your new service are met, protecting your home and satisfying the insurer's requirements.

For an active electrical smell, we treat it as a priority dispatch. From our starting point near Thames Street, we can use I-95 to reach most Groton Heights addresses within that 5-8 minute window. Do not attempt to reset the breaker again. That smell often indicates a failing connection at the breaker terminal or a damaged bus bar, which requires immediate professional diagnosis to prevent an arc fault or panel fire.

This is typically a combination. Eversource's overhead lines in our area are susceptible to ice and wind, causing momentary grid fluctuations. However, if your home's electrical system lacks proper protection, those external surges travel inside. Your sensitive 2026 electronics, like routers and smart devices, need defense. Installing a whole-house surge protector at your main panel, compliant with NEC 2023, will clamp these transient voltages before they reach your outlets.

Overhead service masts are exposed to the coastal weather. We frequently see mastheads corrode, service cable insulation degrade from UV exposure, or the mast itself loosen from wind load. This can lead to water ingress into your meter base or a complete mast failure. During a panel upgrade or inspection, we check the mast's structural integrity, the weatherhead seal, and the condition of the service drop conductors from Eversource to ensure a secure and watertight connection.

Start with a load calculation on your 100-amp service to understand its limits. For winter, ensure critical circuits for heat and refrigeration are clearly labeled for a potential generator hookup, using a proper transfer switch to avoid back-feeding the grid. For summer reliability, consider a service upgrade to handle central AC without brownouts. A whole-house surge protector is also critical year-round to shield electronics from ice-storm induced grid switching surges.
