Frequently Asked Questions
What's involved in getting a permit from the Littleton Building Department for a panel upgrade?
As a New Hampshire Electricians Board licensed master, I handle the full permit process. For a panel upgrade, the Littleton Building Department requires a detailed application with load calculations and equipment specs. All work must comply with NEC 2020. After inspection, they issue a certificate of compliance. You never deal with the red tape; we ensure the project is filed, inspected, and closed correctly.
My 1961 Littleton home has original cloth wiring. Why do my lights dim when I use the microwave and space heater together?
Your home's electrical system is now 65 years old. Cloth-jacketed copper wiring from that era was not designed for the simultaneous loads of modern 2026 appliances like microwaves and space heaters, which can draw 15-20 amps each. This causes significant voltage drop on the 100-amp service, dimming lights and overheating wires. Downtown Littleton homes with this original infrastructure often need a panel and service upgrade to handle today's safe capacity.
The breaker panel in my Downtown apartment smells like burning plastic. How fast can a master electrician get here?
For a burning smell at the panel, dispatch is immediate. From our shop near the Littleton Opera House, we're on I-93 and can typically be at your door within 3-5 minutes. This is a fire-hazard priority, so we'll secure the main breaker on arrival and diagnose the source—often a loose connection at an overheated bus bar or a failing Federal Pacific breaker.
How can I prepare my Littleton home's electrical system for a -20°F winter storm and potential brownout?
Winter heating surges strain an older 100-amp service. Before peak season, have an electrician verify all connections at the panel and service entrance are tight to prevent heat buildup. For brownout protection, a professionally installed manual transfer switch and generator provide essential backup. We also recommend AFCI breakers, required by NEC 2020, to prevent arc faults from overtaxed, aging circuits.
My home on the rocky hillside near the river has frequent minor power flickers. Could the terrain be a factor?
Yes. The rocky soil in Littleton's river valley can challenge grounding electrode systems, leading to poor earth connection and erratic neutral performance. Combined with heavy tree canopy on hillsides causing line interference to overhead services, this can create flickering. An electrician should test your grounding resistance and inspect the masthead service for tree contact.
I have a 100-amp Federal Pacific panel and want to install a heat pump and EV charger. Is my current setup safe for that?
No. A Federal Pacific panel is a known fire hazard due to breakers that fail to trip, and a 100-amp service from 1961 lacks the capacity for major additions. Installing a Level 2 EV charger or a heat pump requires a full service upgrade to at least 200 amps and replacement of the recalled panel. We handle this as a single project with Littleton Building Department permits to ensure your system is both powerful and safe.
I see the overhead power lines coming to my house. What are the common issues with this type of service in Littleton?
Overhead mast service, common here, exposes your home to weather and wildlife. Ice accumulation can weigh down the service drop, damaging the mast. Squirrels and birds can cause shorts or outages. We inspect the mast head, weatherhead, and service entrance cables for integrity. Ensuring proper mast height and securing the service wires prevents many of these issues.
My smart TV and computer keep resetting during Littleton ice storms. Is this an Eversource grid problem or my wiring?
It's likely both. The Eversource grid in our region experiences moderate surge risk from seasonal ice storms, which can cause momentary outages and voltage spikes. Your 1961-era wiring and panel lack modern whole-house surge protection. Installing a service entrance surge protector at your meter and point-of-use protectors for electronics defends against these grid events.
