Commercial Electrical Services in Colebrook, NH
New construction, fit-outs, service upgrades and lighting for businesses across the North Country.
When your business depends on power, you need an electrical crew that understands commercial work — not a residential electrician squeezing a business job in between house calls. Belknap Electric handles commercial electrical projects across northern New Hampshire's North Country and Vermont's Northeast Kingdom, from our shop at 12 NH Rte 145 in Colebrook. Owner Jason Belknap is a New Hampshire Master Electrician (License #13566M), is also licensed in the Vermont side (#06050), and the company is fully insured. We take on new construction, tenant fit-outs, service upgrades, lighting retrofits, dedicated equipment circuits, backup power, and the ongoing maintenance that keeps a building running safely.
Commercial electrical work is a priority for us, and it shows in the range of businesses we serve. We work on auto dealerships, schools, hospitals and healthcare facilities, and manufacturing plants — each with its own demands and its own code considerations. That means we plan around your schedule, keep the work area clean, and communicate clearly so there are no surprises. Whether you are opening a new location, expanding an existing one, or bringing an older building's wiring up to today's demands, we bring the same focus: do it right, do it safely, and do it in a way that holds up to daily use.
Auto Dealerships
A dealership runs on lighting — showroom floors, lot lighting, service bays, and the signage that pulls customers in off the road. We handle service upgrades to carry those loads, interior and exterior lighting, dedicated circuits for lifts and equipment, and backup power so a sales floor or service bay does not go dark at the wrong moment. We also take on the ongoing maintenance that keeps a busy lot running safely day after day.
Schools
Schools pack a lot of electrical demand into a building that has to stay safe and occupied. We handle service upgrades and panel changes, classroom and corridor lighting, dedicated circuits for kitchens and equipment, and the maintenance and troubleshooting that keep an older school building running. We plan work around the school calendar and the hours the building is in use wherever possible.
Hospitals & Healthcare Facilities
Healthcare facilities cannot afford to lose power or run on unreliable wiring. We handle service upgrades, lighting for clinical and common areas, dedicated equipment circuits, and backup power coordination so critical loads stay up when the grid drops. We work cleanly and communicate clearly in occupied care settings, and we take on the maintenance that keeps these buildings compliant and dependable.
Manufacturing Plants
Manufacturing runs on heavy, continuous loads and equipment circuits that have to be right the first time. We handle service upgrades and panel changes sized for machinery, dedicated circuits for presses and production lines, high-bay and task lighting, and backup power so a line does not stop dead in an outage. We also take on the maintenance and troubleshooting that keep a plant running shift after shift.

One Local Crew That Knows Your Building
Businesses up here are spread out across the North Country and the Northeast Kingdom, and waiting on a contractor from down south can cost you days. A local crew based in Colebrook can get to your building faster, remembers how your system is laid out, and is close enough to come back when something changes. That continuity matters when your operation runs on reliable power.
"Jason and crew were excellent. Showed up on time and did a great job with a replacement panel with surge protection and generator hookup. Very friendly and explained everything. Converted a rats nest to a professional job. Thank you. Would recommend anytime."
