"Nery and his crew did an excellent job installing both a new electric panel upgrade and a 240V EV charger. They were open to discussing and negotiating a reasonable price and working with the city to have the new panel inspected. I would highly recommend Single Line Electric Company to others and would use their services again if needed."

"I am updating my rating for CA Electrical (Unfortunately Angi will not allow me to edit, so I am posting this as a new review). After posting my original review I was contacted by CA Electrical. The supervisor assured me that my experience was not their normal practice and that they normally made sure to call if there was a change of plans. I felt that they were earnest in trying to make things right, so I agreed to give them another chance. I ultimately decided to select them for my project to replace sub panel and install outlets. The crew was excellent and professional. They showed up on time, were professional and friendly, took extra care to ensure work spaces were left clean. Their workmanship was excellent and they did a great job of cleaning up some messy electrical wiring that had been there before. As an electrical engineer, I also appreciated the crews knowledge of code and ability to explain the technical side of the installation. I would use them again."

"Hamilton Electric was so quick to respond, quoted a price and was able to come out to do the work as quickly as I needed. We had a bit of a delay from PG&E and Brian was very patient and helpful even with the changes in timeline. Technician came out today and was quick and efficient. We thought we would be without power all day, but instead it was only a few hours. We will definitely call Hamilton Electric for any other electrical needs at our home."

"We had a great experience with OSJ Electric working on our garage remodeling project. Ossamu is a very detail oriented person, he thinks out all the possible options and comes up with the final solution. We got our electric panel upgraded, adding another panel and new wiring for adding more capacity, cleared all the walls of conduits and external wiring, running everything inside, installed recess lights, multiple new outlets, new focus lights on the outside moved solar panel to clear wall space and installed Tesla EV charger. The final outcome was much better than what we envisioned. Ossamu’s work is beyond expectation. He is creative and comes up with solutions to any electrical need we have. Their pricing is reasonable for the quality of work and service. I will highly recommend OSJ for any electrical work and would definitely go with them for any future electrical projects."

FAQs for electrical wiring or panel upgrade projects in San Ramon, CA

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.
