Making the switch to an electric vehicle is an exciting step toward cleaner, more efficient transportation. But to get the most out of EV ownership, you need a licensed electrician who understands both the technical requirements and local regulations. R&A Langevin provides expert EV charger installations throughout Southern New Hampshire and Northern Massachusetts — installed safely, efficiently, and in full compliance with NEC Article 625 and all local codes.
Installing a home EV charging station isn’t just about mounting a unit on your garage wall. It requires careful assessment of your home’s electrical infrastructure, proper load calculations, and adherence to safety standards that protect both your vehicle and your property. Based in Pelham, NH, we bring deep knowledge of local building codes, permit requirements, and the unique electrical challenges facing homeowners in our region.

We perform load calculations before any work begins to confirm your panel can handle the continuous 40–60 amp draw of Level 2 charging — or we'll tell you upfront if an upgrade is needed.

Our electricians hold current licenses in both states, meeting all safety requirements and qualifying you for available rebates — including the NH Electric Cooperative's $300 charger incentive.

Every install meets NEC Article 625 requirements — proper GFCI protection, correct grounding, and dedicated circuit specifications for EV charging systems.

We handle all permitting and inspection requirements with your local authority — so your installation is on record, inspected, and fully compliant from day one.
Most homeowners installing an EV charger will want a Level 2 charger, which operates on 240 volts and can fully charge most electric vehicles in 4–8 hours — perfect for overnight charging. Level 2 charging requires specific electrical infrastructure that many homes don’t have in place yet. Here’s what’s involved:
EV chargers are continuous loads under the National Electrical Code, requiring a dedicated 240V circuit sized at 125% of the charger's rated amperage. For a typical 40-amp charger, this means a 50-amp breaker and appropriately sized wiring throughout the run.
We evaluate your existing panel for both physical space and adequate capacity to handle the additional load. Many older homes with 100-amp service may require an upgrade to 200 amps to safely accommodate EV charging alongside other household demands.
Current code requires ground-fault circuit interrupter (GFCI) protection for EV charging equipment. We install GFCI breakers or GFCI-protected receptacles as required by your specific installation and any local amendments to the electrical code.
Proper grounding is essential for safety. We ensure your EV charging circuit is correctly bonded to your home's grounding system, meeting all NEC requirements for fault protection.
We visit your property to evaluate your electrical panel, determine the optimal charger location, measure the distance from panel to charging point, and calculate your home’s current electrical load. This comprehensive assessment allows us to provide an accurate quote and timeline, including any necessary panel upgrades or electrical service work.
Once you approve the proposal, we pull all required permits from your local building department and coordinate inspection schedules. Our licensed electricians then install your dedicated 240V circuit, mount your EV charging station, and ensure all connections meet manufacturer specifications and local code requirements. We work efficiently to minimize disruption to your household.
Before we leave, we thoroughly test your charging station to confirm it’s operating correctly and safely. We provide a complete walkthrough of your new system, explaining how to use it, what maintenance it requires, and answering any questions you have. Your installation is backed by our service guarantee and one-year warranty on workmanship.

Arron and his crew were wonderful to work with. It started with a professional consultation, where Arron ask what our needs were for the bathroom renovation. He offered suggestions and talked through all of my questions. He really took the time to make sure our needs were being met and had great style recommendations and really helped to elevate our remodel. The crew that completed the work were kind, hardworking, and easy to have in our home. They cleaned up after themselves and left the job site looking better than it had when they got there. I would 100% recommendations them to anyone looking for an electrician. They are dependable and fast workers. Worth every penny to know you are having a job done right the first time around. Gary NiggTrustindex verifies that the original source of the review is Google. Just moved into a new house in Littleton wired by Arron and team. My inspector was highly impressed with the organization of the electric panel and the electrician's attention to detail. After closing there were a few items left on the punch list. Arron was responsive, extremely personable, and cooperative. One of his team members Paul went out of his way to come a couple of days earlier than expected. Punchlist is done and I am very happy with how this went. Thanks Arron and Paul! ROSSTrustindex verifies that the original source of the review is Google.

GraceTrustindex verifies that the original source of the review is Google. Arron and team took what seemed like a nearly impossible problem and made it look easy to fix! We had a gas oven and wanted an electric (the plugs in the back of the oven were not compatible) so the entire downstairs needed to be rewired. Arron and his team were so responsive, helpful, professional, and fixed our problem with ease. We really enjoyed working with them and will be using them in the future!! Thank you! George LloydTrustindex verifies that the original source of the review is Google. We have a complicated old house with a history of sub-standard electricians. Every switch in the house needed some level of attention. R&A came in and seriously made it right. Listened carefully to my long list of fixes and went to work in a focused efficient fashion. With some larger stuff that included busting walls and moving switches, these guys were quick on their toes, worked fast through the long list all about the house and cleaned up as though they were never there. Polite, efficient, capable. Great work! We have found our electricians going forward. James PattersonTrustindex verifies that the original source of the review is Google. Immediately responsive when we had a problem and quickly got a great crew out to us who quickly fixed the issue we had, clearly explained what the problem was and were all around fantastic.
