Both lights were over 14 feet high. "

If it is wired, we can help! We offer quality and affordable electrical services.

"Luis of Gav electric came to my house when other electricians kept dropping the ball and not showing up. He took 30 minutes assessing the issues and fixes I needed, gave me a fair quote, which I was astonished at the fair price and honesty that he provided, and said he could start right away. He got started that day and finished by the next day doing a panel upgrade, outlet upgrades and installations, and some recessed lighting along with other minor fixes. I have hired Gav electric for other electrical issues/upgrades that come up and each time Luis shows up promptly, keeps me informed and finishes the work with no delays or excuses. I have not had one issue with any of the work performed. Very professional and skilled electrical contractors."

I started in the electrical union and have experience in residential, commercial and solar electrical. I can do anything from outlet repair and installation, to full panel upgrades. I can quickly install new lighting and/or fans, EV chargers, as well as troubleshooting. I have extensive knowledge in commercial electrical pertaining to panels, switch gears, transformers, wire pulling and conduit installation.

"Ty did a solid job installing 3 GFCI outlets and 1 light switch for my kitchen. He provided a fair/competitive price and executed the work professionally. He was a pleasure to talk to and patient to answer all of my questions. He even left me a free receptacle tester for the safety of my home to test the outlets. Recommend him to anyone that needs electrical work by a professional electrician. 5+ stars"

FAQs for electrical wiring or panel upgrade projects in Winchester, CA

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.
