At Generator Supercenter, we are committed to securing your home and peace of mind with back up power solutions. When bad weather hits or an electrical circuit malfunctions, a power outage is likely. When that happens, you can recover quickly if you own a reliable home backup generator. Once your generator is installed, you’ll need reliable technicians available 24/7 and capable of providing quick services. Generator Supercenter of New Hampshire provides experienced technicians for generator installation, repair, and maintenance. Benefits of working with our team: Full-service – Whether you need a new generator, or your current one is malfunctioning, we won’t leave until your generator is up and running as it should be. Convenience – If something goes wrong with your generator, you don’t have to worry about going out to buy a new one or to replace parts. We will come to your home or business and take care of it for you. Free on-site estimate – When you call us, you’re not committed to a service—our estimates are free, so you can meet with a member of our team to learn about your options with no strings attached! Unfortunately we do not do anything with portable generators or any brands not manufactured by Generac. We are also not a parts distributor.

"Matt Sanford and the team at Generator Supercenter were professional, knowledgeable and efficient when surveying my property. They spent quality time educating me on their generator product line and monitoring services. If you're looking for a superior product, company, and team to support you throughout our long New England winters, look no further!"

We are not currently offering smaller electrical services, including outlets, fixtures, running wire or panels for things that are not in the home like rvs or boats. We only service electrical panel upgrades within the home and the average cost for this service is around 5000$ but cost will go up or vary according to scope of project. At Diamond Electrical Contractors, LLC our training and experience is second to none. For electrical work you can trust, call the professionals at Diamond Electrical Contractors today!

"I am writing to express my sincere appreciation for the outstanding work performed by Diamond Electric during a recent electrical service upgrade at our property. From start to finish, the entire crew demonstrated professionalism, punctuality, and exceptional craftsmanship. They arrived on time, communicated clearly throughout the process, and completed the work efficiently and safely. What stood out most was their attention to detail—even the smallest aspects of the job were handled with care and precision. It’s not often that you come across contractors who combine technical expertise with such a strong commitment to quality and customer satisfaction. I would not hesitate to work with them again, and I highly recommend their services to anyone in need of electrical work."

Electrical questions, answered by experts

The American Wire Gauge system calculates wire size diameters using the complicated formula D(AWG)=.005·92((36-AWG)/39) inch. A simpler rule of thumb is that every six-gauge decrease doubles the wire diameter, and every three-gauge decrease doubles the wire’s cross-sectional area. On the other hand, wavenumbers are typically measured in reciprocal meters (1/m or m−1) or reciprocal centimeters (1/cm or cm−1).

When installing an outdoor outlet, it's important to proceed with caution. Unless you have the necessary training and licensure, it's not recommended to attempt this DIY. First, choose a suitable location. Make sure that the area can accommodate the outlet without overloading the circuit. You'll also need to ensure that your project complies with building codes. Next, turn off the power to the circuit, then install and wire the outlet according to the manufacturer's instructions. Once the outlet is in place, test it. Lastly, be sure to use a cover that will protect it from moisture and other weather-related damage.

No, wiring does not need to be redone to get a dimmer switch, as they work with single-pole and three-way switches. Just ensure you choose a dimmer that is compatible with your wiring, fixture, and lightbulbs. Most homes built after 1985 have neutral wiring and work with almost all dimmers. If your home was built before 1985 and you don’t have an updated electrical system, you may have to use a non-neutral wiring dimmer.

Most LED bulbs have a plastic covering, while incandescent bulbs will be made from glass. This is because LED bulbs don’t produce as much heat as incandescent bulbs, so the covering doesn’t need to be as heat resistant. Also, an LED light bulb will usually have a marking on its base that identifies it as an LED.

At a minimum, you need an electrician to inspect the house wiring after a fire. The electrician will need to replace damaged or melted wires. If the electrical wiring is old, about 25 years or more, you should rewire the house after a fire. Old wiring can increase the risk of another fire, so replacing the wires is the safest option.
