"Called in Current Electric for an emergency call as we had power out in one room, but no sign of a thrown breaker in the panel. Seemed to be some discrepancy with how the emergency call was dispatched; we called Friday and were told we needed to call later to reach the tech on-call. No, we are calling now for that. No call back on Friday evening, but Saturday we received a call from the on-call electrician asking if we still needed service -- yep, so he came out the same day. Once he was on site, he quickly diagnosed the issue (loose wire connecting to neutral bar causing arcing) and fixed it up quickly. No issues with the quality of service that Circuit provided once we had a tech on-site. Cost listed below takes into consideration the fact it was charged as emergency service, so does not truly reflect cost of parts/labor (which would have been lower during a normal priority call)."

"Preston and John were both excellent, very professional, and kept us informed at all stages of the work. Joani and I were so pleased with the work they did on running the wiring. installing the 8 recessed lighting fixtures, installing the 3 ceiling fans and installing outdoor electrical outlets that we ran out and got 2 more ceiling fans for them to wire in and install. We would recommend them without reservation!"

"Jim was a very good communicator and was able to give a general estimate over the phone based upon an inspection report we provided to him. They were able to come within our timeframe of a week, and did excellent work. Whenever my husband or I contacted Jim about anything, he always got back to us in a very short time. One of the best experiences I have had with any contractor. We would definitely hire again."

"Very friendly and communicative. Upgraded our electric panel and also happened to notice our doorbell wasn't working and helped with that too! Registered contractor with Focus on Energy so costs for panel upgrade are reduced based on income. Absolutely will call again when future needs arise."

"Two guys showed up for a one man job. They did not use the parts I had purchased with one exception. Only one guy worked at one time and both disappeared for an hour or so. Two switches and two light fixtures installed cost nearly six hundred dollars!"

"I needed a new circuit breaker panel installed. They were on time, did great work and cleaned up all of the mess. They also installed my Starlink and did internet wiring for me. I was extremely happy with the price and the work preformed. "

"He does good work, but charged for the 2nd hour despite all the work being completed in the first hour. I asked for estimates on some other projects, but he was not able to offer a free estimate that ultimately did not include a price or a time frame."

"Both technicians were prompt, professional, clean and courteous. You cannot tell that anyone was even here they did such a good job cleaning up. We had a small wiring job (new breaker circuit and multiple outlets) to be quoted and Electrician Mike completed the job immediately following the estimate. HVAC Mike arrived shortly after and completed the overdue checkup on our furnace. He even cleaned the filter on our dehumidifier -- I didn't even know it had one, lol! We will be doing a remodel on our main floor soon and will have Cardinal out to do the electrical, plumbing and gas for the job. My wife has commented twice already about how well they cleaned up after completing their respective projects!"

"Matt came right out and fixed two light switches that weren't working for one of my customers. He was quick, efficient and very professional. We especially appreciate it because it was done a Friday and we called at the last minute. We highly recommend them and will call them for all of our electrical needs in the future!"

"Did a great job on fixing my outside electrical issue of the circuit that kept tripping. Fixed so both outside outlets did not trip at same time. Unable to hardwire my security doorbell/camera where I wanted due to house being over 100 yrs old. He did however did offer some alternatives but not what I wanted. Overall really satisfied with the job he did & explaining what needed to be done "

FAQs for electrical wiring or panel upgrade projects in Sun Prairie, WI

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.
