Questions and Answers
My Sandown Center house was built in 1991 and still has the original wiring. Why are my lights dimming when the microwave and space heater run together?
Your 35-year-old NM-B Romex wiring is likely struggling with a modern 2026 appliance load it wasn't designed to handle. Circuits from that era were planned for far fewer high-demand devices. Simultaneous use of heating appliances and kitchen electronics can overload a single 15 or 20-amp circuit, causing voltage drop you see as dimming lights. A capacity evaluation of your 150A service panel and circuit layout is a prudent next step.
We have a lot of tall trees around our property near Sandown Town Hall. Could that be causing our intermittent electrical issues?
Heavy tree canopy directly impacts electrical health. Branches contacting overhead service drops or mast heads can cause arcing, interference, and intermittent faults. Furthermore, the root systems and rocky, uneven soil common in our terrain can compromise your home's grounding electrode system over time, leading to erratic breaker trips and poor equipment performance. An inspection should assess both the overhead service condition and the ground rod integrity.
My smart lights and router keep resetting during storms. Is this from Eversource's grid, and what can I do about it?
Eversource's grid in our area faces moderate surge risk, especially from seasonal ice storms that can cause line faults and momentary outages. These micro-surges and brownouts are particularly hard on sensitive smart home electronics. Installing a whole-house surge protector at your main service panel, compliant with NEC 2020 standards for Type 1 or 2 protection, is the most effective defense for your devices.
I need a panel upgrade. What permits and codes do I need to follow in Sandown, and does the electrician handle all that?
All panel work requires a permit from the Sandown Building Department and must comply with the adopted NEC 2020 code. As a master electrician licensed by the New Hampshire Electricians Licensing Board, I secure the permit, schedule the required inspections, and ensure the installation meets all current safety standards, including AFCI breaker requirements and proper grounding. This process protects your home's value and ensures your insurance coverage remains valid.
My power comes from an overhead line on a mast. What are the common maintenance issues I should watch for with this setup?
Overhead mast service, standard in Sandown, is exposed to the elements. Common issues include mast head corrosion, weatherhead seal failure allowing moisture into the conduit, and service cable wear from swaying in the wind. Heavy ice accumulation can also stress the mast and connections. Regular visual checks for these signs, especially after severe weather, are important. Any repair to the mast or service entrance conductors requires a permit from the Sandown Building Department.
I'm in a 1991 Sandown home with a 150A panel and I want to add a Level 2 EV charger. Is my current electrical system safe and sufficient?
A 150A panel from 1991 provides moderate EV charger compatibility, but a load calculation is essential before installation. More critically, we must verify your panel brand. Many Sandown homes from that era have recalled Federal Pacific panels, which pose a serious fire hazard and must be replaced before adding any significant new load like a 240V EV charger or heat pump. Safety and code compliance come first.
I smell something burning from an outlet and the power just went out in part of my house. How fast can a master electrician get to me in Sandown Center?
For an urgent issue like a burning smell and partial power loss, we dispatch immediately. From our start point near the Sandown Town Hall, we can use NH-121A for direct access, aiming for a 5 to 10-minute arrival window. Our first priority is to safely isolate the fault at your panel to prevent a potential fire, then diagnose the damaged outlet or wiring.
How should I prepare my Sandown home's electrical system for winter ice storms and potential brownouts when the heating is running full blast?
Winter heating surge during a -10°F cold snap strains the entire electrical system. Start with a professional inspection of your heating equipment's dedicated circuits and connections. For backup during extended outages, a properly installed and permitted generator with a transfer switch is key. We also recommend point-of-use surge protection for critical electronics, as power restoration after an ice storm often comes with damaging voltage spikes.
