"Marsh River traveled over an hour to come out to my house to redo my electrical from the panel to the pole, put the wires underground (because they were not before) put a new electrical box and meter on the pole. Did a great job and knew exactly what they were doing! Just a side note: I thought the reason the outlets on the back wall of my room didn’t work was because of mice eating our wires. Whoever did the electric before must not have done it correctly because the outlets are now working!"

"I hired this company to do electrical run from my house to my shed. I was so impressed with their work and then reasonable price for the work they did. I had another problem with electric in my kitchen. I called them to come and fix it which they did in a short amount of time for a reasonable price. I would call them anytime."

"Called right away. Came over the same day. I had anticipated a more complicated problem (circuit breaker or panel), but Mike quickly found and fixed a simpler (but atypical) problem: defective GFC in the circuit outlet."

"I hired Bill to change a 15amp outlet to a 20amp. The job was more in depth than I anticipated because of the distance from circuit breaker to outlet location and the need for new wiring. We discussed discussed other location possibilities, but Bill was confident he could complete the job as I had planned. He did so with absolute confidence and professionalism. Much appreciated!"

"After one of the snowstorms we had this last winter, we found ourselves without electricity. A tree had fallen across our power line, ripping the electric meter off the house and hurling it across the lawn. Perhaps it is needless to say that we felt like the helpless prey of the Universe. On the advice of a friend, we called C. B. Electric. This company proved to be fast and reliable. Their charges were reasonable. They were polite, really nice and reassuring people. They told us when they would be here, and they came when they said they would, which was only a day or two later. They immediately started a search for a replacement meter. When they got that, their work was fast and was performed with what I like to call "snappy exactitude." We absolutely could not have been better pleased. Electricians just don't get better than this."

FAQs for electrical wiring or panel upgrade projects in Long-island, ME

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.
