Q&A
Why do my smart home devices keep resetting during storms in Londonderry? Is it Eversource's fault?
Eversource manages the grid, but seasonal ice storms and lightning in our area create moderate surge risk. These transient voltage spikes can bypass basic power strips and damage sensitive electronics. Installing a whole-house surge protector at your main panel, rated for the service entrance, is the most effective defense. It clamps these surges before they reach your circuits and smart devices.
My power comes in on an overhead mast. What should I watch for with this type of service?
Overhead mast service, common here, is exposed to the elements. Visually inspect the mast head and weatherhead for ice damage, rust, or animal intrusion. Ensure the mast is securely anchored to the house structure. The service drop conductors should have clear clearance from trees and roofs. Any sagging lines, damaged conduit, or loose connections at the mast require immediate attention from a licensed professional to prevent a safety hazard.
I found a Federal Pacific panel in my basement and want to add an EV charger. Is this safe?
Federal Pacific panels have a known failure rate and are not considered safe for continued use, especially under new loads. Your existing 100-amp service from 1983 also lacks the capacity for a Level 2 EV charger, which typically requires a 40-60 amp circuit. The necessary full service upgrade to 200 amps will include replacing the hazardous panel, providing a stable foundation for modern electric vehicles and heat pumps.
Does the wooded, hilly land around Mack's Apples affect my home's electricity?
The rolling hills and dense forest common in this area can impact electrical health. A heavy tree canopy near overhead service drops can cause interference and increase the risk of limb-related outages. Rocky soil found in hills can also challenge proper grounding electrode installation, which is critical for safety. An inspection can verify your grounding system's integrity and assess any tree-related service line hazards.
Do I need a permit from the Londonderry Building Department to replace my electrical panel?
Yes, a permit is legally required for a panel replacement or service upgrade. The Londonderry Building Department must review the work to ensure it complies with the current NEC 2023 code and local amendments. As a master electrician licensed by the New Hampshire Electricians Licensing Board, I handle the entire permit process, from application to final inspection, ensuring the installation is safe, documented, and adds value to your home.
Who do I call for an electrical emergency like a burning smell or total power loss in Londonderry?
For a burning smell or sparks, shut off power at the main breaker and call 911 first, then a licensed electrician. From a landmark like Mack's Apples, our service truck can typically reach most North Londonderry homes via I-93 in under 12 minutes for urgent dispatch. Having a master electrician diagnose the fault at the panel prevents further damage and ensures a code-compliant repair.
My 1983 house in North Londonderry has flickering lights when the air conditioner kicks on. Is my original wiring too old?
A home built in 1983 is now over 40 years old. The original NM-B Romex cable is generally safe if undisturbed, but it was installed for a different electrical lifestyle. Modern loads from multiple large-screen TVs, computers, and kitchen appliances can exceed the original circuit design, causing voltage drops that appear as flickering. An assessment can determine if your 100-amp service and branch circuits need updating to meet 2026 demands safely.
How can I prepare my home's electrical system for a winter ice storm and potential brownout?
Winter heating surges and ice storms strain the grid. Beyond a whole-house surge protector, consider a hardwired backup generator with an automatic transfer switch. This system provides essential power during an outage and prevents damage from frequent utility brownouts. Ensuring your panel and wiring are in good health before the peak season reduces the risk of failure when you need heat the most.
