Does Your Panel Need an Upgrade?
Electrical problems rarely fix themselves. If you're noticing these issues, it's time for a professional assessment. Not sure? Our troubleshooting service can diagnose the root cause.
Breakers Trip Frequently
Circuit breakers that trip regularly signal your panel can't handle your home's electrical load.
Flickering or Dimming Lights
Lights that flicker or dim when appliances turn on indicate insufficient capacity.
Panel Feels Warm or Buzzes
Heat or buzzing sounds from your panel are serious warning signs of loose connections.
Relying on Power Strips
If you need power strips everywhere, you've outgrown your electrical system.
Older Homes
Older homes often need rewiring and panel upgrades for modern demands.
Planning for EV or HVAC
Adding an EV charger, heat pump, or whole-home generator? These often require 200-amp service.

Is 100-Amp or 200-Amp Service Right for Your NH Home?
Most older homes across southern NH and northern MA were wired for a fraction of the load a family runs today. Here is how the common service sizes stack up.
| Service Size | What It Comfortably Powers | Best Fit For |
|---|---|---|
| 100 Amp | Lights, standard outlets, one AC unit, and gas heat. No room for a Level 2 EV charger or a heat pump. | Small older homes and condos that have not added big electrical loads. Usually the first candidate for an upgrade. |
| 150 Amp | Central AC plus an electric range and dryer, with a little headroom left over. | Mid-size homes that stop short of EV charging, a heat pump, or a workshop. |
| 200 Amp Standard | The full modern load: HVAC, electric range, heat pump, Level 2 EV charger, and a finished basement, all at once. | The current standard for most NH and MA homes. This is the upgrade we install most often. |
The only way to size your service for certain is an on-site load calculation. Brenden does that free, before he quotes a number.

Panel Upgrade FAQs
Most 200-amp upgrades in New Hampshire start around $3,000, and a same-size panel swap starts near $1,800. The final number moves with the condition of your service entrance, meter base, and grounding. You get a written quote after a free on-site assessment, and no work starts until you approve it.
Many 100-amp panels need an upgrade for Level 2 EV chargers. We assess your capacity during a free consultation. Learn more about EV charger installation.
Most panel upgrades are completed in one day. Complex installations may take 2-3 days.
The federal Energy Efficient Home Improvement Credit (IRS Section 25C) used to offer up to $600 toward qualifying panel upgrades. Under the 2025 federal tax law, that credit ended for any work completed after December 31, 2025, so it does not apply to new 2026 installations. Some state, local, or utility rebate programs may still help, and these change often. Check with your local utility and a tax professional for what currently applies to your project. This is general information, not tax advice.
Yes, we handle everything - permits, utility coordination, inspections, and ensuring everything passes code.
It depends on your town. Eversource serves most of southern NH, while Unitil covers Seacoast towns like Hampton and Exeter. In northern MA, that role falls to National Grid. Moore Electric files the disconnect request with whichever utility serves you and schedules the reconnect once the panel passes inspection.
