"The team at Current Electric was very friendly, professional, and knowledgeable. Work was performed well. Communication and punctuality were top notch. My only minor complaint is they are on the pricier side of electrical contractors. But with most work you get what you pay for."
Current Electric is locally owned and operates from Wauwatosa, WI.  We've been serving SE Wisconsin since 1983.
Our team did all of the electrical design and installation for this beautiful kitchen.
Whether you are building a new home or just need a few new outlets, Current Electric can accommodate all of your electrical needs.

Customers say: Quality work

"Jim & his team did a great job fixing the electrical system in my new house. The house had an ancient relay system from the 50s. Excel did all of the work on time & in budget. Because the system was so old there were random issues that popped up later. Jim & his team came back right away every time I called. I highly recommend Excel Electric."

"We had our house inspected and found an old mouse nest in one of the electrical panels. The buyers wanted it looked at to make sure no wires were cut or bad. The service guy came was able to come out 2 days after we called. He looked over the box, made a few wires cuts, and plugged the access holes in the bottom of the box so that no more rodents could enter. He also checked out our bathroom light to make sure it was code (we have crazy buyers) without any charge. All in all, he was quick and inexpensive.

"Very communicative! Not only did they call me back, they got in touch to let me know about anything that impacted my appointment. I also really liked how everything they do is on a menu with set prices. It was also great to have the work done the same day as the quote, since the work I needed done could be completed in an afternoon. The electrician also presented estimates for options and work that may need to be done in the future. WireOne will be my first thought next time I need electrical work."

"Unstoppable Electric LLC just installed our Tesla Wall Connector, and wow—what an incredible experience. They were super responsive from the first message, easy to schedule, and showed up right on time. Max is very knowledgeable, professional, and genuinely nice to talk to. He took his time to do everything perfectly—clean, precise, top-quality work with no rush whatsoever. Explained everything clearly, made smart suggestions, and left the garage looking flawless. Pricing was fair and transparent—no surprises. Definitely now my go-to electrician in the area! 10/10 recommend! Thanks again for the stellar work! ⚡️🚗"

"Hired Precision Power twice to help with various electrical needs… rewired my kitchen and then again to help with the finish trim outs. We will continue to hire him. Currently just waiting for our new chandelier to arrive so we can have him back out again! Thanks for the quality work and dependability!"

"This is a truly great company. They provide great customer service and spend time explaining the details and answering questions. My husband obsessed about every single detail and could not deny that it was a no brainer. Our first electric bill since installing the panels was a CREDIT! I was not expecting that. If you have ever considered solar, seriously, just do it. Long term, you can not go wrong."

Electrical questions, answered by experts

Although homeowners can turn off a breaker, it’s vital to follow safety precautions when doing so to prevent serious and potentially fatal injuries. For instance, you want to ensure there is no water on the floor when you touch the breaker and wear protective gear such as safety glasses. Anytime you deal with anything electrical, it’s always best to be as safe as possible.

A 100 amp electrical service panel can't convert into a 200 amp panel simply by switching the breakers or adding circuits. Upgrading from 100 to 200 amps typically requires replacing the circuit box and updating the electrical service coming into the house. Your electrician will handle the details of the project to ensure a safe and thorough installation.

The size of your home will help determine the size of your electrical panel. Usually, the decision comes down to a 100-amp electrical panel versus a 200-amp panel. Smaller homes, especially those without an HVAC system, may be able to get by with a 100-amp panel. 

If you have a larger home or need to power AC, a 200-amp panel should be the best fit. It’s unlikely that you’ll need a larger panel than that unless you have a larger home or unique electrical needs, but an electrician can help you make the final call.

Electrical fires are unique from other fire types because they have the potential to deliver electric shocks in addition to being on fire. Avoid serious injury from possible electrical emergency situations by avoiding the use of water, foam-based fire extinguishers, wet-chemical fire extinguishers,  flour, or baking powder to put out an electrical fire. 

On average, replacing an electrical breaker panel, such as the Federal Pacific Electrical breaker panel, costs about $1,300. The price range for replacing electrical panels is between $550 and $2,100, depending on your location, the electrical panel’s location, and the extent of the work required to replace the panel. This kind of electrical work is dangerous and should only be done by a licensed electrician.
