"Martin called back as soon as I contacted Atomic Electric. I explained that a 20 amp circuit breaker would not remain set for more than 15 minutes, and might need to be replaced. He said replacement might not be necessary, and pointed out that a faulty/shorted lamp might be the cause of the problem. He was right. Saved us both a lot of time and effort. I will certainly call Atomic Electric again, should any other electrical issues arise."

"They did an awesome install and even installed a sound bar and Steven stayed to help debug some Comcast connectivity issues. That was really outside of what he was sent to do but he hung in there until I was able to watch a movie! Also, Bronson helped me find a better value on my TV purchase through them. A+ plus customer service all the way around and everyone was so pleasant to work with. Yes, I probably could have either gotten it cheaper or even had some of my friends help out and install it. But, when they would have finished, I would have been hiring someone else to repair or replace the drywall. Sometimes, you get what you pay for. Would definitely hire them again for future projects! Thanks Bronson and Steven!"

"Greg came on schedule and discussed the project with us. He suggested LED pancake lights and dimmer. We originally planned to put in lights on either side of the room. He e-mailed a price by the end of the day. It was a fair price but over our current budget. We really only needed the lights on one side of the room (over the new office area), so I asked Greg to revise the estimate. It was not trouble and he did not try to push me into the original quote. We agreed on the price and he scheduled the work. Brennan came promptly and even texted me when he was close by so I could put the dog in another room. He completed the work very efficiently, cleaned up everything and was just awesome really. Everything is wonderful!!! I have found my electrician from now on!!!"

"Contracted to install new panel which will support plug in generator. Installed what I needed/ wanted, no up sell. His estimate was reasonable, but unlike other contractors, he did not ghost me, he showed up when scheduled and did the job."

FAQs for electrical wiring or panel upgrade projects in Knoxville, TN

Yes, a licensed electrician is essential for this project. Running an electrical service from the road to your house involves connecting to utility power lines, complying with national and local electrical codes, and safely handling high-voltage systems. 

Licensed professionals understand proper wire sizing, grounding requirements, and voltage drop calculations needed for safe installation. Most jurisdictions require permits and inspections that only certified professionals can obtain. The safety risks and potential for property damage make this project inappropriate for DIY attempts.

Overhead installations are less expensive than underground options. For a 1000-foot run, overhead service costs between $8,000 and $15,000, while underground service ranges from $10,000 to $25,000. 

Overhead lines require less labor and fewer materials since they don't need trenching or conduit. However, underground lines offer better protection from weather events and aesthetic benefits. Your decision should balance your budget constraints with long-term reliability and visual preferences.

You might need to upgrade your electrical panel depending on your power requirements. If your existing panel cannot handle the additional load from the extended service, upgrading to a 200-amp service (costing $750 to $2,000) may be necessary. 

A licensed electrician can evaluate your current system and determine if an upgrade is required. Factors include what you'll be powering at the end of the line, existing electrical demand, and whether voltage drop over the distance will affect performance.

Running electric service from the road to a house requires electrical permits from your local building department, costing between $500 and $2,000 depending on your location. You may also need excavation permits for trenching work if installing an underground service. Your utility company will have its own application process for connecting to its grid. A licensed electrical contractor can handle all the necessary permit applications as part of their service, ensuring your installation meets all local code requirements.
