"New washer was causing circuit breakers to flip on my electrical panel. Mr. Handyman, who does my home repair and maintenance, referred me to McCurdy Electric emphasizing that they are the best in the business. Contacted McCurdy Electric and from that first phone call was in great hands. From Judy in the Office to Owner John who came out to meet and prepare estimate, professional and kind all the way. Logoed truck, always on time. Upgraded service to 100 AMP. Shebeeb and Brandon dug the trenches, ran the wires and quite honestly worked hard getting me back up with electricity before they left. McCurdy Electric even pulled the required permits and met with the City Inspector at my home. Just sat back with a book and let the professionals do their magic. Will not hesitate to contact them the next time I need electrical work done. Five Stars. --Charlene in West Peabody, MA"

"Jason and his team upgraded and replaced the electrical panels, meter sockets, and most of the outlets at a multi-family property I own. They did incredible, clean, safe work. And even communicated with the tenants! They made everything easy, and the inspection passed with flying colors. Incredible job!"

"Peter and his team did a panel upgrade for us when we bought our house in 2021. They completed tidy and well-labeled work on a tight deadline, exactly as planned, on one of the hottest days of the year. I was really impressed at the time with the clear communication about when they'd do different phases of work, what we needed to arrange with the town electric company, etc. More recently, one piece of conduit came unglued and they came by to fix it almost immediately, free of charge. I'm really impressed with this crew's standards."

"Brandon responded to my call immediately. He set up a time to meet and his co-worker Will showed up promptly as scheduled.He installed a 4 prong 220 outlet. He is very honest because he saved me $100 by using the existing wire when i thought he would need to run new wire. Both Brandon and Will were very professional and took the time to explain what they were doing. I would recommend Phillips Electrical without hesitation."

"John and crew upgraded the house to 200amps, bringing everything to code and cleaning up prior panel on top of installing new panel. Hookup of EV charger in garage was exactly to my request. They showed their experience with EV by suggesting and helping us attain rebates to help with costs. We are very satisfied with our EV charger installation."

FAQs for electrical wiring or panel upgrade projects in Cambridge, MA

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.
