"Fred arrived on time, and was courteous, friendly, knowledgeable, and efficient. It was a simple problem to fix: we just needed to press the reset button on one of the outlets. Fred found the right outlet hidden behind some stuff, pressed the button, and voila! All three outlets started working. Here's the good part: He in no way made us feel foolish for not figuring it out for ourselves. I would not hesitate to call him again."

"Evans Electric was very responsive, which is becoming rare for most service providers. We had a 61 yo fuse panel that was a fire hazard and was replaced with a circuit breaker panel. Matt was quick to provide a quote and scheduled the service for the same week. He came on time and finished the job much quicker than we expected. Definitely five star service."

"These guys are the best! I had an EV charger installed and their bid beat the competition by $1k. They arrived when they said they would. They were respectful of our property and our time. There was great communication throughout. And their work was outstanding! The city inspector took five minutes, basically said "these guys obviously knew what they were doing," and he immediately signed off on the work. And Joe, our electrician, is friendly, creative, and efficient-- a real pro! I will definitely use Mr. Electric for all of our future electrical needs!"

I chose to work in this industry because I was always interested in electrical, and was offered to enroll in an apprenticeship program with my first electric company in Nashville, TN. It was mostly a commercial company. There I gained lots of valuable knowledge. After graduating from the 4 year trade school I became a foreman. Then moved back to Dallas TX to work for a residential service company. I also enjoyed this aspect of electrical. There is more troubleshooting involved. The owner of this company taught me a lot and we still keep in touch. Then I moved to North Carolina to pursue my own business. I can do most commercial and residential projects. I look forward to hearing from you.

Electrical questions, answered by experts

Most 200-amp panels have 40 to 42 slots, which can accommodate 40-42 single-pole breakers or 20 double-pole breakers. Some panels can accept even more circuits through the use of tandem breakers. The exact number of breakers allowed is determined by the panel manufacturer's rating, which you can find on the panel itself. It is important to avoid using all breakers at the same time; as a general rule, you should not use more than 160 amps of power at once to prevent overloading your 200-amp system. For specific guidance, it's best to check your panel's rating or consult with a qualified electrician.

If your thermostat does not have a C-wire, you can hire a professional to check for an abandoned C-wire hidden in the wall, install a new C-wire, repurpose an existing G-wire to function as a C-wire, or purchase a C-wire adapter kit. 

There are some smart thermostat models that do not require a C-wire, but this will limit the functionality of the smart technology.

Modern homes have a lot of devices and appliances running at once. That means there are many different wires and cables throughout the house. Service entrance conductors (also known as service entrance cables or service feed wires) connect the external weatherhead for the utility pole to the circuit breaker box. This is your home’s connection to your local power grid.

When combined with a substantial solar system, if you have enough Powerwalls, you could go off-grid and be energy independent. But remember, you'd need enough Powerwalls to power your whole home continuously because a single Powerwall can’t power large appliances for extended periods. One Powerwall is able to power an average-sized home's emergency circuits, lights, and outlets. To power large appliances, you likely need two or three Powerwalls.

It’s not a good idea to mix LED and incandescent Christmas lights if you can avoid it. LEDs and incandescents can have significantly different electrical current needs. This difference can lead to a higher risk of problems and failure for both light strands. When possible, switch all your lights over to one kind or the other for the best results. Do not connect the different types of light strings to each other, and avoid linking them to the same circuit.
