"I loved working with Dalcon. From the estimate and working with Zachary to the excellent wiring by Reggie and Christian, they are very professional. I had an ancient main panel replace with a newer larger main panel. In addition they added 6 new circuits. The main panel wiring was so well done that the inspector said he had not seen work that good in years. Dalcon is expensive but I believe that it was well worth it."

"Excellent service. I needed to upgrade my electric panel, Ben did an excellent job very professional. Installing switches, circuit breaker panels, relays, and other electrical control and distribution equipment was the right call. I look at several electricians with reasonable prices and CA Electrical Group was definitely the right call. I will highly recommend CA Electrical Group to all my friends. What was important to me was his daily commitment to start and finish the job the dates we agreed on."

"Jacob installed my new EV charger. He did an excellent job taking great care in cutting my drywall in the garage to access the main panel outside and then place the wiring in a manner that was as hidden as possible- all at a very fair price. I would recommend him highly and will call on him for future jobs."

"Ray gave me a call while I was in the process of finding an electrician to troubleshoot a wiring problem at our office space. I told him that some of the outlets were working while some of them were temperamental. Ray came to the office with a sense of urgency, and not only checked out the electrical panel, but looked at every individual outlet that was not working. He explained what the problem was in great detail, and was very confident that he could fix the problem, and scheduled for two of his workers to come out the following day to tackle the issue. They were able to fix it in about an hour, and everything is working perfectly now. I immediately asked for a way to give a review, so here I am right now. 10/10!!!"

FAQs for electrical wiring or panel upgrade projects in Portola Valley, 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.
