Question Answers

I smell something burning from an outlet. How fast can an electrician get to my house near the South Dennis Free Public Library?

Treat any burning smell as an immediate fire hazard—shut off power at the breaker and call. For a verified emergency, we dispatch directly from our local base. From the South Dennis Free Public Library, we can typically be on-site within 5-8 minutes using Route 6. That rapid response is critical to prevent a smoldering connection inside your walls from escalating.

Our lights dim when the air conditioner kicks on. Is this just old wiring in our 1976 South Dennis Historic District home?

It's a common sign your electrical system is showing its age. Your original NM-B Romex wiring is now 50 years old and was designed for a much lower appliance load than a 2026 household demands. The 100-amp service panel, standard for its time, is now at capacity with modern electronics, multiple kitchen devices, and central air. This strain on an older system can lead to overheating connections and is a primary reason for service upgrades in the neighborhood.

How should I prepare my home's electrical system for a Cape Cod winter ice storm or a summer brownout?

Preparation starts with a professional inspection of your service mast, meter base, and main panel connections for weather integrity. For winter, ensure your generator transfer switch is properly installed and permitted to avoid back-feeding dangerous power onto the grid. For summer peak loads, consider a managed energy audit to balance your AC usage with other large appliances, reducing the risk of an overload during a brownout. Whole-house surge protection is recommended year-round.

We have very sandy soil here on the flat coastal plain. Could that affect my home's electrical grounding near the library?

Absolutely. Proper grounding relies on good soil conductivity, which sandy soil often lacks. This can lead to higher resistance on your grounding electrode system, potentially compromising surge dissipation and the safe operation of GFCI and AFCI breakers. During an inspection, we test grounding electrode resistance and may recommend driving additional ground rods or using a ground enhancement material to meet NEC requirements for your specific soil conditions.

We have overhead lines coming to our house. Does that make us more vulnerable to power outages than homes with underground service?

Overhead service lines are more exposed to weather, trees, and salt air corrosion, which can lead to more frequent localized outages. The mast where the service drop attaches to your house is a critical point of failure in high winds. The key is ensuring your mast, weatherhead, and service entrance cables are in sound condition and properly secured. While underground service is generally more reliable, well-maintained overhead service with a properly installed mast is perfectly safe and code-compliant.

Our home inspection flagged a Federal Pacific panel. Is this why we can't add an EV charger or heat pump to our 1976 house?

Yes, the Federal Pacific panel is the first and most urgent issue. These panels are known for faulty breakers that fail to trip during overloads, creating a serious fire risk. Even if it weren't for that brand, your existing 100-amp service is insufficient for adding a Level 2 EV charger or a modern heat pump. Both require a dedicated 240-volt circuit and significant capacity, making a full service upgrade to 200 amps the necessary and safe path forward.

Our smart TVs and computers keep resetting after storms. Is this an Eversource grid problem or something in my house?

It's often a combination. Eversource manages the grid, which faces moderate surge risks from our coastal storms. Those surges travel into your home and can damage sensitive electronics. However, if the problem is isolated to your property, it could point to outdated whole-house surge protection or loose service connections. Installing a UL 1449 Type 2 surge protective device at your main panel is a standard defense to supplement any utility-level protection.

I want to upgrade my electrical panel. What do I need to know about permits with the Town of Dennis and Massachusetts electrical codes?

Any service upgrade or panel replacement requires a permit from the Town of Dennis Building Department and a final inspection. The work must comply with the 2023 NEC, which is the current enforceable code in Massachusetts. Only a licensed electrician holding a license from the Massachusetts Board of State Examiners of Electricians can pull this permit. We handle the entire process, ensuring the installation meets all code requirements for AFCI protection, grounding, and load calculations before scheduling the required inspections with the town and utility.
