Electrical Work for Home Additions in NH, MA & ME
Adding a room, garage, or in-law suite changes what your electrical system has to handle. Moore Electric Inc. is your home addition electrical contractor in NH, MA, and ME - handling wiring, panel upgrades, permits, and inspections start to finish, by a licensed Master Electrician.
Your Existing Panel May Not Be Enough
When planning a home addition, the electrical systems are one of the first things a licensed electrician needs to evaluate. Most homes built before 2000 weren't designed with today's loads in mind. Add a bedroom, garage, or finished basement and you're asking your system to do more than it was wired for.
That's not a problem - it just needs to be planned for from the start. As your home addition electrical contractor, we assess your current panel capacity, design the wiring services for your addition, and handle every step from rough-in through the final inspection. No handoffs, no coordination headaches.
- Panel capacity assessed before any work begins
- All circuits planned for how you'll actually use the space
- Permits pulled and inspections scheduled in NH, MA & ME
- Coordinated with your GC or builder throughout the project
- 100% code-compliant work, every time

Electrical Wiring Services for Home Additions
From the first walkthrough to the final inspection, here's what's typically included when you hire a licensed electrician for a home addition project.
Panel Evaluation & Upgrades
We check your existing panel before any work begins. If it can't support the addition, we'll recommend the right upgrade. Most additions require at least a 200-amp panel if you don't already have one.
Rough-In Wiring
All wiring installed during the framing stage before drywall goes up. We coordinate with your builder or GC to hit the right window so the project stays on schedule.
Lighting Design & Installation
Recessed lighting, ceiling fixtures, accent lighting, and dimmer controls planned around the room layout - not just dropped wherever is easiest to wire.
Outlets & Dedicated Circuits
Code-required outlet spacing, GFCI protection where needed, and dedicated circuits for mini-splits, appliances, home offices, or EV chargers.
Kitchen & Bath Circuits
Additions with kitchens or bathrooms require specific circuit configurations - small appliance circuits, exhaust fans, GFCI and AFCI protection - all to NEC standards.
Permits & Final Inspections
We pull all required electrical permits in NH, MA, and ME and schedule the inspection. Your addition won't have loose ends when it comes time to close out the project.
Kitchen & Bath Electrical for Home Additions in NH
Kitchens and bathrooms in home additions require specialized electrical installations due to NEC safety requirements around water proximity, appliance loads, and ventilation. Moore Electric Inc. handles kitchen and bath electrical work with dedicated circuits, GFCI protection, and AFCI breakers as required by code.
| Service | Description | Why It's Required |
|---|---|---|
| Dedicated Appliance Circuits | Separate 20-amp circuits for refrigerators, dishwashers, microwaves, and other high-draw appliances | Prevents overload and tripped breakers from shared circuits; code-required for kitchen appliances |
| GFCI Outlets | Ground Fault Circuit Interrupter outlets installed at all countertop receptacles, bathrooms, and wet-area locations | NEC 2023 requires GFCI protection within 6 feet of any sink; protects against shock in wet areas |
| AFCI Protection | Arc Fault Circuit Interrupter breakers on bedroom circuits and living space circuits in the addition | Required under NEC 2023 for all 15 and 20-amp circuits in living areas; reduces arc-related fire risk |
| Small Appliance Circuits | Two dedicated 20-amp circuits for countertop appliances in kitchen additions | NEC requires a minimum of two small appliance branch circuits for any kitchen |
| Exhaust Fan Wiring | Bathroom exhaust fans wired to a dedicated circuit or switched independently from lighting | Required ventilation for bathrooms without operable windows; code-required in new additions |
| Under-Cabinet Lighting | Low-voltage LED task lighting wired into a dedicated circuit, controlled by a dimmer switch | Improves kitchen functionality and adds resale value; best installed during rough-in phase |

Many Additions Require a Panel Upgrade
If your home has a 100-amp panel - common in homes built before 1990 - adding significant square footage can mean upgrading to 200 amps, depending on your current load and what the addition will demand. It's not always required, but it's worth checking before any work starts. A new panel sets your home up for decades of reliable power. We'll tell you straight whether you need one and give you honest pricing upfront.

Here's what to expect when you hire us for your home addition project.
Walkthrough & Scope
We meet on-site to review the addition plans, assess your current panel, and scope out the full electrical package. You'll get a clear proposal before anything starts.
Permits Pulled
We file the electrical permit with your town or city. In NH, MA, and ME, all electrical work on an addition requires a permit and inspection - we handle it so you don't have to.
Rough-In & Panel Work
Once framing is up, we run all wiring, install boxes, and handle any panel upgrades. Timed to your build schedule so nothing holds up your GC.
Rough-In Inspection
The inspector reviews wiring before drywall goes up. We're on-site and address anything that needs adjustment on the spot.
Trim-Out
After drywall, we install all devices - outlets, switches, fixtures, and cover plates. Everything gets tested before we leave.
Final Inspection
We schedule and pass the final electrical inspection. Your addition is fully permitted, code-compliant, and ready to use.
We Handle Permits in NH, MA & ME
Electrical permit requirements vary by state and municipality. We know the process in each market we serve and handle filing on your behalf.
NH License #14511
NH follows NEC 2023 with state amendments. Addition work requires a permit filed with the local building department. We coordinate with your town's electrical inspector from rough-in through final sign-off.
