"All Solution Electric came and installed bathroom fans in two of my bathrooms, and were very patient and helpful throughout the process as some hurdles arose in terms of the fans I had bought being faulty (thanks cheap Amazon quality control), waiting while I ran to purchase a new fan that day, installing around the old construction ?character? of the house, and coming back to quickly fix a wiring issue. The price was also totally reasonable and I?d recommend them to anyone needing electrical work done. They?re great guys and I?ll work with them again if the need arises."

"I could not be more pleased with DiMasi Electric. We were having an issue with some outlets in our kitchen. The DiMasi team was super responsive from our initial inquiry through completion of the job. As soon as I explained the issue, they knew how to solve it, and when they arrived exactly on time a few days later, had it fixed in an hour. They were also very upfront about pricing and came in well below the estimate they provided us. DiMasi will be our first call the next time we need electrical help!"

"Adam and his apprentice arrived early. Job involved some investigation to find the problem. Adam explained everything as he went along. While checking out the breaker panel, he recommended I upgrade the breaker panel, soft sell, but explained and showed frayed wires and with my ok, did the upgrade right then. With some work in tandem with his apprentice, they found the original issue that I had called for. House is over 40 years old, I think they worked efficiently to find and fix the problem. Adam came prepared for the work at hand as well as upgrading the breaker panel and two outside outlets. I’m extremely impressed with Peak Power NH. Both guys were very professional and explained everything thoroughly. I will use them again if needed and have already recommended them to a few family members. "

FAQs for electrical wiring or panel upgrade projects in Concord, NH

While homeowners with substantial electrical knowledge might technically attempt a subpanel installation, most local building departments require permits and inspections for this type of work. Professional electricians understand local code requirements, can obtain necessary permits, and ensure the installation meets safety standards. Given the significant safety risks associated with incorrect electrical work, most homeowners benefit from hiring a licensed professional.

A standard subpanel installation takes an average of four to eight hours. This timeframe may extend if you're installing multiple subpanels or adding specialized circuits like those for spa equipment. Factors such as difficult access points, complex wiring paths, or permit processing times can also affect the overall project duration.

Adding a subpanel doesn't directly reduce electricity consumption or lower your utility bills. A subpanel simply redistributes power from your main panel to additional circuits. However, organizing your electrical system more efficiently may help prevent overloaded circuits and the associated problems. For actual cost savings, consider energy-efficient appliances and lighting instead.

The appropriate subpanel size depends on your specific electrical requirements. Consider the number and type of devices you'll be powering, potential future needs, and the capacity of your main electrical panel. An electrician can perform a load calculation to determine the most suitable amperage rating for your situation, ensuring you have adequate power without overpaying for unnecessary capacity.

A main electrical panel connects directly to your utility's power supply and contains your home's primary service disconnect. It distributes electricity throughout your entire house. A subpanel, by contrast, receives power from the main panel and redistributes it to a specific area of your home. Think of the main panel as the primary distribution point and the subpanel as a secondary branch that extends your electrical system's reach.

While electrical upgrades aren't as immediately visible as kitchen or bathroom renovations, they can contribute to your home's functionality and safety. Prospective buyers often appreciate updated electrical systems that can accommodate modern power demands. A properly installed subpanel that provides additional capacity for workshops, home offices, or future expansions could be an attractive feature for certain buyers, though the direct impact on home value varies by market.
