"Ted and his crew were prompt, professional and got the job done in the time estimated. They understand how to deal with permitting, inspections and scheduling each step in the process. Specifically, Ted is very familiar with local nuances in each city, related to inspections. My house, being an older structure with older wiring and an oddly placed riser pole, was not a straight forward project, but it was no problem for the crew. They completed the work as planned, kept a clean job site and were very courteous throughout the project. I was very pleased with the work done by the Apollo and would hire them again and highly recommend them to others."

"I hired JC Electric (Jaime) for two projects: a panel upgrade and an EV charging installation. In both cases, Jaime was meticulous, reliable, and highly skilled, ensuring the projects were completed on time. Beyond his expertise, he is an honest and trustworthy professional. I would gladly work with him again on future projects and highly recommend his services."

"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."

"I've used Alphonso several time for various jobs. The first job was to diagnose a HVAC unit that was not working. Another was to install electrical conduit on the outside of a house for motion lights. Another time was to pull wire in order to create a 220 A outlet for an electric range. The most recent job was to check the wiring of an older home and upgrade the 2-prong outlets to 3-prong. Each time Alphonso did an outstanding job. He was punctual, professional and performed all of the work lawlessly. He rates are competitive. I will continue to use Pellegrin Electric/Alphonso for every future electrical need."

"The team at Avant is next level. From planning, to prep and through final inspections, Avant’s skilled approach allows the home-owner to get from ideation to ”finished” without any pressure to do more than our budget allowed. We upgraded our panel; moved the PG&E drop so the wifi meter was no longer next to our master suite; installed a new EV fast-charger; installed a new home security system; upgraded indoor and installed new automated outdoor lighting AND re-wired all our 220a appliances. I’d recommend Avant for any home-owner seeking high value excellent workmanship!"

FAQs for electrical wiring or panel upgrade projects in Cupertino, 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.
