"I have found my forever electricians (at least while I live in the New Haven area)! From start to finish my experience with Power Forward was an absolute pleasure. Company owner, Ian, was responsive, punctual, and incredibly informative when it came to walking me through the details of the scope of work I was requesting, and was thoroughly transparent and fairly priced when it came to his estimate. Once we accepted the quote, scheduling with Morgan was easy and efficient, and Chris arrived onsite within a day of me accepting the estimate. Chris was a consummate professional, a super clean worker when it came to caring for our house and the cleanliness of his cable paths, and was truly dedicated to doing the job â the right wayâ not just the easy and cheap way. He took his time and planned his cable runs and circuiting carefully to ensure both minimal cutting into our walls and convenient receptacle placement. Once he was finished, he took care to clean every area heâ d worked in and probably left some of the rooms cleaner than when he arrived! I would recommend Ian and Power Forward to anyone who appreciates work that is done with care, safe, and efficient. I think you get what you pay for when it comes to hiring trade professionals, and electricity is not something you want to cut corners with: hire Ian and his team, and have it done right and safe the first time."

Electrical wiring or panel upgrades FAQs

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.
