"I will recommend Champion Electrical Services to anyone interested in hiring competent, reliable and honest electricians. It starts with salesmen Jayron Diaz who submitted the job estimate to upgrade an electric panel to code. There was no surprise costs. Jayron was very professional and honest about the work. On the day of the service, Matt Wood and Sean arrived at the scheduled time as promised. Matt explained what they were going to do, how long it would take, and if I had any questions. Matt estimated the job would take approximately 6 hours. It actually only took 4 hours from start to finish and that included cleanup and minor repairs. I think Champion did an awesome job and I will call upon them for my next project."

"They were the only company to respond quickly get me a quote. All the other companies listed near me on angies list were heavily booked or gave me a quote site unseen that I felt was extremely high. Scott came in and inspected the site before hand and gave me a fairly priced quote. We scheduled a date that had to be moved a few times because of weather. That isn't their fault as the install was outside. Eventually we got a good day and Scott came with another tech and got it all wired up and tested quickly. It is working perfectly and I haven't had any issues what so ever."

"Had a Tornado hit my house and ripped out my mains power. Figured I'd upgrade the panel while I was at it and have a generator outlet installed for when I lose power again. Nick was VERY professional - gave me a quote, showed up on time, answered all of my questions, and the price was exactly where I expected it to be. Job was very well done. When the power went back on, my fridge didn't have power. He helped me pull the fridge out to find a GFI outlet, and he helped me reset it. Was really just a huge help! The guy is clearly a hard worker who really knows what he's doing. What I love is that I didn't talk to a sales guy who then sent a couple of kids to do the job. I got a quote, and the guy I spoke to did the work. That's awesome. I can't recommend this guy highly enough! Will reach out for any and all electrical work in the future."

"Everything went perfect from start to finish. Chris responded to my inquiry that very evening and we set up a date to have an estimate for the replacement on my old fuse box panel. Randy his technician went through everything in detail that needed to be done to upgrade my sevice to 200 amps and the added safety features. At that point I knew I had the right person for the job. I signed the contract that day to have the work done. Randy and his co-worker (sorry forgot his name) arrived on time and completed the work that day and for the exact price I signed the contract for. I'll be calling them back in September to have more work done. Don't hesitate to call Chris."

The team was professional, arrived on time, and completed the work efficiently with great attention to detail. Their pricing was very reasonable, and the quality of the work exceeded our expectations. Everything was clean and working perfectly when they finished. I would definitely recommend them to anyone looking for reliable and professional electrical work."

"I recently had Cristian upgrade my electrical service, and I couldn’t be more pleased with the experience. From start to finish, Cristian was polite, professional, and extremely knowledgeable. He took the time to clearly explain everything he was doing, which gave me a lot of confidence in the work being performed. What really stood out was his patience and attention to detail. He made sure every part of the job was done carefully and correctly. I would absolutely use Cristian again and highly recommend him to anyone looking for a skilled and trustworthy electrician"

FAQs for electrical wiring or panel upgrade projects in Harmony, RI

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.
