"The crew from Grifffin Electric repaired fixed the wiring issues for a 100 AMP breaker box from a recent construction job. There were several wiring issues that was corrected. The crew (Buzz and Chris) were on time, very professional and explained in details what was wrong and the necessary fixes. The repairs were easy and it didn't take much time. I would use Griffin Electric again and I do recommend them. Very Professional"

"The breaker had flipped. But they did check my outlet and wiring to ensure everything was okay. Explained why it flipped and how many volts or currents certain outlets in my house would hold."

"Mr. Electric of Greenville did excellent work. They were on-time, clean, and courteous. They replaced our electrical panel, and despite having to work through a number of difficult issues they stayed until all of the work was completed. I will definitely plan to hire them again for my next electrical work project."

"The rep suggested several improvements including upgrading to a solar heating system. We are now in the process of installing a solar heating system. With government tax incentives over the next 2 years we will finance $15K. If I just keep paying what I was paying for my monthly power bill towards the solar panels and upgrades the payback is less that 7 years. After which, my electricity is free. System has a 30 year warranty. Looking forward to the installation and will provide feedback once it is installed and in operation."

"The electrician from Star Power Electrical Contractors was absolutely amazing! When I first tried upgrading my own panel from a YouTube video, I got electrocuted and felt completely defeated. But then this guy shows up, friendly, professional and not an ounce of judgment. Hes the Planet fitness of electricians! Thankyou Star Power for turning my frown upside down!"

"My job was simple, so David was able to give me a quote over the phone. Once I asked him to do the job, he scheduled it in two days. Patrick and Jeff installed a new breaker, wiring, and crawl space outlet. They were professional, courteous, efficient, and to my wife's surprise, Patrick swept up the mess when they were finished. I will definitely call David for my next electrical project!"

FAQs for electrical wiring or panel upgrade projects in Greenville, SC

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.
