"While they did a great job job with the installation there was no instruction on the runn of the generator such as how to operate the em shut off switch. As far as as I know they didn?t test to see if the generator work properly if the power was off. Also we were told by the per who gave us the estimate that if we went with Cote Electric that we would receive 6 sealed hardwired combo smoke wired smoke and co2 detectors which we?ve heard nothing about and it been almost 3 weeks since installation"

"I called Fralick electric on Memorial day in the evening because I had problems with my electric panel. I sent him over some pictures and he knew right away what was wrong. He told me he could be over in the morning. The next day he came in replaced my electric box within three hours. He did a great job at a very reasonable price. I would definitely hire them again."

FAQs for electrical wiring or panel upgrade projects in Plymouth, NH

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.
