"Very professional and extremely friendly contractor. Alberto and his apprentice Chandler arrived on time and after introductions started their work. Panel upgrade with breaker and wiring installation was performed efficiently with only necessary disruption to home electrical service. Testing completed and panel breaker labeling done from old panel door. Cleanup was thorough and appreciated. I enjoyed the conversation we had during and after the job including my own DIY electrical experience. If I was going to sum my experience with A & A Electrical Contractors LLC, it would be that it is a great model for professionalism and consumer oriented business. I was given more options than other contractors. Reasonable contract pricing. Highly recommended and definitely a return customer for any future electrical needs requiring experienced professionals.

"Upgraded to a 200 Amp service and added a lockout switch for a generator. He did an excellent job with the work. Biggest problem was working with the town and he was always communicating the status of the problems and able to work them out. Very good customer service."

"I have known Doug and his son Mark from On the Grid Electric for many years. They have done electrical work for myself, my family and friends as well as a number of my real estate clients. They are knowledgeable, dependable and honest. They make sure that everything is done correctly and meets or exceeds code. It’s why I don’t hesitate to recommend On the Grid Electric, LLC."

FAQs for electrical wiring or panel upgrade projects in Glastonbury, CT

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.
