"Very responsive business and communicated every step of the way. From what he diagnosed I had a bad wire in the ceiling of the garage that shut my breaker off and wouldnâ t reset. I had no lights or plugs in the basement for days as I tried to figure it out myself. He came in and was easily able to diagnose, fix, and get it all back up minus the one plug that relies on the one dead wire. Iâ ll be putting that in since Iâ m taking my ceiling down anyways. He has all the experience needed and professionalism a master electrician is. Definitely will hire again and will recommend to anyone who needs an electrician."

"I have used these guys for six or seven projects now and they are amazing. I have used them both for heating and cooling and their electrical services. John and Brian are amazing electricians and more importantly just great and fun to be around people. I would recommend them to literally anyone and I trusted them to work on my parents home. My lifelong contractor told me that they were the best electricians he's ever worked with. I really cannot sing their praises highly enough and if you have any hesitation about them I hope my review is somewhat helpful in allaying them. Their work quality is top notch and they're professionalism cannot be beat."

"Biagiarelli designed, installed a complete network with smart home automation. I asked Ben to use Homeseer and he did a great job. He also programmed Smart Pool Hayward. This was a very complex project which also included 200+ speakers, 32 zones of sonos, complete wife install, new alarm, under cabinet lighting, outdoor landscaping lighting and so much more. I highly recommend Biagiarelli Electric, especially if you need a technologically inclined electrician. He is friendly, knowledgable and reliable for installations and support :-)"

FAQs for electrical wiring or panel upgrade projects in Groton, CT

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.
