Ace Electric Company is a full service Electrical Company estabished in 1985 and we have built our reputation on honesty with integrity.We are licensed, insured and bonded. Our primary work area is Knoxville and surrounding counties and service has been our business for 30+ years. Ace Electric takes pride in our work with the goal of having repeat customers and recommendations. We feel the best advertisement is a satisfied client.

"I love Ace! This is a 1950s house with one of those low voltage switching systems that is failing. Other electricians would insist that the house had to be completely rewired in 8 rooms, which would be tens of thousands of dollars. I found Ace and asked them to help us avoid the rewiring, and bypass the switching system. They installed new wireless switches and in-line receivers to control all the overhead lights in 8 rooms. It worked perfectly and at a very small fraction of what rewiring would have cost. Chad and his crew were very prompt and professional, knowledgeable and service-oriented. Everyone that I dealt with in the office, from scheduling to billing, was great as well. On top of all that, I was way out of town and had to coordinate all the appointments and even some of the work remotely. Highest recommendation."

Electrical questions, answered by experts

If the outlet is a GFCI model, this is normal since these outlets have their own breakers that shut off when they encounter a problem—just hitting the reset button should solve the issue. Otherwise, the outlet could have bad wiring, or your circuit breaker could be having issues. If the issue started out of nowhere and is not on a GFCI outelt, it’s best to contact an electrician to diagnose the issue.

You can make a pigtail with either thermoplastic high-heat-resistant nylon-coated (THHN) wire or non-metallic (NM) cable, often referred to as “Romex.” Each pigtail requires a neutral wire, a ground wire, and a live wire. The gauge of your pigtail wires must match the gauge of those on the device. 

A piggyback circuit breaker, also known as a tandem or double-stuff breaker, combines two separate circuits into a single slot in a breaker panel. This design allows adding more circuits without a larger panel, making it a space-saving solution. Each breaker in the piggyback unit operates independently, protecting two circuits in one standard breaker slot. This is especially useful in older panels with limited space for additional breakers.

The light that your ceiling light gives off will largely depend on the type of light bulb that’s installed in it. If you’re looking to brighten a dark room, LED bulbs are the way to go. LED bulbs will emit the most light while also using less energy than standard bulbs. They can last up to 50,000 hours and will need to be replaced much less often than standard bulbs.

Yes, overheating outlets can cause fires, even if nothing is plugged in at the time. If your outlet is too hot, turn off the circuit breaker, unplug everything, and let it cool down before troubleshooting the issue. Fortunately, outlet fires are rare, but if a fire starts, suppress it with a Class C fire extinguisher or baking soda—or leave the area immediately and call the fire department.
