Q&A
Can my 1985-era 100-amp panel handle adding a heat pump or EV charger?
Safely, no. A 100-amp panel from that period is likely already fully loaded. Installing a Level 2 EV charger or a heat pump circuit would require a service upgrade to 200 amps. This is especially critical if your panel is a Federal Pacific brand, which is a known fire hazard and must be replaced before adding any new major loads.
Why do my lights flicker during storms here in Seabrook?
Flickering often stems from Unitil's overhead distribution lines, which are susceptible to wind and ice during our moderate-surge-risk coastal storms. These grid disturbances send minor voltage fluctuations into your home, which can damage sensitive modern electronics like computers and smart TVs. A whole-house surge protector installed at your main panel is the recommended defense.
Do I need a permit from Seabrook to replace my electrical panel?
Yes, any panel replacement or service upgrade requires a permit from the Seabrook Building Department and must be performed by a master electrician licensed by the New Hampshire Electricians Licensing Board. The work must comply with the current NEC 2023 code. As your electrician, I handle securing the permit and scheduling the required inspections to ensure your system is legal and safe.
Why do my lights dim when the microwave runs in my Seabrook Beach home?
Your home's electrical system is now about 41 years old. Original NM-B Romex wiring from 1985 was sized for fewer, less powerful appliances than a 2026 household uses. The standard 100-amp service common in that era simply lacks the capacity for modern, concurrent loads from air fryers, computers, and HVAC systems, which can cause voltage drops seen as dimming lights.
Does living on the flat coastal plain near the beach affect my home's electricity?
The flat, sandy soil common around Seabrook Beach can create a high-resistance path for your home's grounding electrode system. This may reduce the effectiveness of surge protection and fault clearing. An electrician should verify your ground rods achieve a low-resistance connection as per code, which is crucial for safety during a lightning strike or utility surge.
What does having an overhead service mast mean for my home's power reliability?
Overhead service masts, common in this area, are your home's physical connection to Unitil's power lines. They are exposed to coastal weather, tree limbs, and aging. A mast in poor condition can lead to intermittent power or even pull away from the house. An inspection can identify if yours needs resecuring or upgrading to handle a modern 200-amp service.
My power is out and I smell something burning from an outlet, what should I do?
First, turn off the main breaker in your panel and call for emergency service. From Seabrook Town Hall, a licensed electrician can typically reach Seabrook Beach in 8-12 minutes via I-95. Do not attempt to reset the breaker or use the outlet, as a burning smell indicates an active fault that requires professional diagnosis to prevent a fire.
How should I prepare my home's electrical system for winter ice storms?
Winter heating surges and ice storms that can drop temperatures to 5°F place a heavy strain on the grid and your home's wiring. Ensure your heating system is serviced and your panel is free of Federal Pacific or other recalled breakers. Consider installing a generator with a proper transfer switch to maintain heat during an outage, protecting your pipes and family.
