"Apollo Electric is a great company. Came out and scoped out the job and made some very nice money saving suggestions before hand. Day of the job they were onetime With a crew of 3. Unpacked all their equipment finished the entire job and packed and cleaned up in under 3 hours. They even gave me some suggestions about wiring and box placement. I would check these guys out. Great service, great suggestions and very friendly."

"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."

"Wonderful experience. Prompt, courteous, professional, honest and personable. They installed a new electrical panel which passed city inspection. The inspector complemented them on their attention to detail. An extra bonus for me was they accepted credit card payments, awesome! Will definitely hire them again for my next job."

"Saul and Juan arrived on time, determined where the fault lay, advised me on what I can do to save some labor costs by running wire myself. I have worked on some electrical equipment over the years so usually am familiar with what is needed or not needed. These guys didnâ  t try to sell me something I didnâ  t need. Very professional and I would recommend them to others. Thx. Brian Napa County"

FAQs for electrical wiring or panel upgrade projects in San Jose, 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.
