"Our project was a panel upgrade and generator install. From the first point of contact through point of completion Kevin's level of professionalism, customer service and follow through were beyond exceptional. He is very skilled and knowledgeable in the electrical field. He was able to answer all of our questions and we knew we made the right choice. Once the scope of work was determined and a date/time established he arrived on time and completed the work promptly and neatly. We are extremely pleased with Kevin's work. In fact we have other electrical projects planned in the near future and we will be reaching out to Kevin. For anyone searching for an electrician Kevin is the right person and I can assure you that you will not be disappointed."

From the moment I contacted him for an estimate, I was impressed by their professionalism and promptness. They arrived on time, fully equipped, and ready to tackle the job. They explained everything clearly, answered all my questions, and offered valuable advice on how to improve the safety and efficiency of my electrical systems. The quality of work was exceptional – they completed the job efficiently and left the work area clean and tidy. I also appreciated their transparency regarding costs, with no hidden fees or surprises. I highly recommend JB Electrical to anyone in need of electrical services.

"I had Harland Electric come out and check out my electrical panel due to an issue where the electric dryer kept tripping the circuit breaker. (There was water near the breaker that I observed when it did this.) I had a few other minor things I wanted to have them check at the same time. The guys (Kevin and Derek) were great and knowledgeable and recommended I replace the panel due to the corrosion. I got an e-mail from Bill Harland who gave me information on what my options were and some estimates. I asked a bunch of questions and Bill was a great help in making a final decision. I felt he was honest about his recommendation as I debated doing a more expensive upgrade and Bill felt for my situation it would be overkill. I opted for a full replacement 100amp with the feed from the outside. (My house is very small and 100 amps has always been more than sufficient) Kevin and Mike showed up on time for the appointment and did an awesome job on the replacement. The work was high quality, neat and professional. The guys were also great around the young children (2 and 5), they very friendly and even my wife was comfortable (and that's impressive). They cleaned up completely and even took care of a couple of additional things that I had hoped (but didn't expect) they'd be able to get to. There were no surprises with the bill and within the estimate (even with the extra stuff). Judy in the office was also very nice and great with setting up schedules and dealing with the deposit. I will definitely use Harland again if I need electrical work done."

FAQs for electrical wiring or panel upgrade projects in North Chelmsford, MA

A whole-house surge protector blocks voltage spikes from lightning, grid issues, or even large appliances before they can fry your wiring or electronics. By diverting excess current at the main panel, it shields everything from your HVAC to your phone chargers and can extend the life of pricey appliances. Homeowners in storm-prone regions or with older panels see the biggest payoff, but any home that relies on sensitive electronics benefits.

Most whole-house surge protectors work for two to three years. Low-level spikes—too small to notice—hit your panel every day and slowly wear down the internal components. Once the unit’s capacity is depleted, it can’t prevent a larger surge, so plan to replace it on schedule (or sooner if a major lightning strike occurs) to keep your electronics and HVAC equipment safe.

A surge protector begins guarding your circuits the moment an electrician snaps it into place. Whether the spike originates from a nearby lightning strike or your fridge kicking on, the protector shunts the extra current to ground before it can reach outlets or hard-wired systems, such as your AC. That instant response is why a small upfront cost can save thousands in appliance repairs.

The unit mounts on or next to your main electrical panel. Type 1 models sit on the supply side, catching outside spikes before they hit the breaker. Type 2 devices snap inside the panel and tame surges that start within the house. Either way, placement at the panel lets the protector guard every circuit at once.

Plan to swap the device every three to five years—or sooner if you upgrade your panel, add high-demand appliances, or notice flickering lights and tripped breakers. Relying on a maze of power strips is another red flag that your current setup isn’t keeping up. Replacing the surge protector at these milestones keeps your electrical system on safe footing.
