"I recently hired Gary to upgrade my electrical panel, install new backyard lighting, redo some outdated wiring throughout my home and install a sauna — and I couldn’t be happier with the results. From the beginning, he was incredibly professional, communicative, and punctual. He took the time to walk me through the scope of work, explained everything clearly, and provided a fair and transparent estimate. The backyard lighting installation turned out beautifully and as for the wiring, he did a clean and thorough job, correcting issues I didn’t even know existed. It’s clear he takes pride in his work, and I really appreciated the attention to detail and safety. Highly recommend Gary if you’re looking for a skilled, trustworthy electrician. "

"Voltaic Electric Inc. completed a ?whole-house rewire? at my home in July 2025, but by January 2026 multiple outlets failed. A licensed electrician found unsafe wiring, including 110V wiring used in a 240V system, and we even noticed a burning smell. This is a serious fire hazard. Very disappointed and still waiting for them to take responsibility and fix it."

FAQs for electrical wiring or panel upgrade projects in Simi Valley, 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.
